NOAA KLM User's GuideSection 4.1 |
The High Resolution Picture Transmission (HRPT) system provides data from all spacecraft instruments at a rate of 665,400 bps. The S-band realtime transmission consists of the digitized unprocessed output of five AVHRR/3 channels, plus the TIP (HIRS/3 for NOAA KLM and HIRS/4 on NOAA-N, -P, SBUV/2, SEM, DCS/2) data and AMSU data. All information necessary to calibrate the instrument outputs is included in the data stream.
During NOAA-K activation and evaluation, it was determined that AMSU-A channels 7 and 15 were switched. This switch should be transparent to Level 1b users as the channels were corrected (switched back) by the ingest software, however, direct readout users should be aware of this problem. Only the radiometric data was affected, the housekeeping temperatures of channels 15 and 7 oscillators are correct as they are now. The antenna patterns, beam efficiency and beam widths are correct as they were not affected by the switch. Band pass for channels 7 and 15 was not affected due to extremely broad rf-detectors.
The S-band transmission of time multiplexed, digital data is in a split phase format. For NOAA KLM, split phase data "0" is defined as being +68 degrees phase during the first half of the bit period and -68 degrees during the second half of the bit period. The split phase data "1" is defined as being -68 degrees phase during the first half of the bit period and +68 degrees phase during the second half of the bit period, for NOAA KLM. Note, the NOAA-N,-P satellites have a slightly different phase angle (see Table 4.1.2-2). Table 4.1.2-1 shows the general characteristics of the HRPT transmission system, while the general HRPT parameters for both NOAA KLM and NOAA-N,-P are shown in Table 4.1.2-2.

The MIRP outputs the HRPT format simultaneously with the Automatic Picture Transmission (APT), Global Area Coverage (GAC) and Local Area Coverage (LAC) formats. GAC and LAC data are not considered real time, as these data are stored on the spacecraft digital recorders for readout by the CDA stations. The HRPT data format consists of a major frame which is subdivided into three minor frames.
Of special note is the flag in the telemetry (Word 7, Bit 10) which will indicate which of AVHRR/3 channel 3 sensors (3A or 3B) is operating. When channel 3B is selected, the patch temperature data is output every scan line (during the backscan), and every other scan line when channel 3A is selected. The data output will switch instantaneously between 3A or 3B upon command, even if the scan is in the middle of a line. However, the way the flag operates there is one scan line of uncertainty when switching from 3B to 3A, and two lines of uncertainty when switching from 3A to 3B.
On NOAA KLM, TIP and AMSU data are updated at the major frame rate. That is, the three minor frames which make up the major frame will contain TIP data in the first minor frame, backfill in the second minor frame, and AMSU data from the AIP, in the third minor frame. In the previous series of satellites (NOAA E-J), the major frame consisted of three minor frames of only the TIP data. The details of the HRPT, AIP, and TIP minor frame formats for NOAA KLM are shown in Tables 4.1.3.1-1, 4.1.5.1-1 and 4.3.3.1-1, respectively.
Table 4.1.3.1-1 describes the minor frame format for HRPT on the NOAA KLM satellites.

On NOAA-N,-P, the HRPT format provides a major frame, which is made up of three minor frames. TIP and AMSU/MHS data are updated at the major frame rate. That is, the three minor frames, which make up a major frame, will contain TIP data in the first minor frame, backfill in the second minor frame, and AMSU/MHS data in the third minor frame. The HRPT is provided in a split phase format to the S-Band Transmitter. The S-band transmission of time multiplexed, digital data is in a split phase format. The split phase data "0" is defined as being +67 phase during the first half of the bit period and -67 phase during the second half of the bit period. The split phase data "1" is defined as being -67 phase during the first half of the bit period and +67 during the second half of the bit period. The time code contained in each minor frame indicates the spacecraft time 1.13 ± 0.5 milliseconds before the beginning of bit 1 of word 1. The HRPT minor frame format for NOAA-N,-P is shown in Table 4.1.3.2-1.

| Note: 1) For S/N 102 only: Read PRT temperature. Read voltage of lock detect signal and convert to temperature using the following formula: t=(8.75 x V)-23.5 where t is the temperature (in C) and V is the measured lock detect voltage signal. If the temperature given by the PRT reading and the formula are in agreement within ±5 C, then use the PRT reading as it was intended. If the temperature difference is greater than ±5 C, then use temperature interpreted from lock detect signal. At initial power on of PLLO#2 before PLLO#2 is fully self heated and stabilized, use within ±5 C rule with reference to A1-1 (PRT #33) RF-shelf temperature. The within ±5 C rule does not apply right after PLLO was operational and was switched off and then back on. In this case, wait half an hour for PLLO#2 to cool down before temperature extraction method can be selected correctly. The formula t=(8.75 x V)-23.5 is useable only between 2.5V to +8.4V or -1.6 to 50 C. | ||

Digital Data is clocked into the spacecraft AIP at a 16.64 kbps rate by the shift pulse whenever the Data Enable Pulse is presented to the instrument. The AMSU-B data is in the AIP minor frame words 48 through 97. The AIP reads the digital data output from the AMSU-B in 16 bit words.
The AMSU-B telemetry format consists of 78 minor frames of data. Minor frames 1 and 80 in each 8 second cycle are blank: i.e., no data is available in the PEU digital data FIFO during the first and last minor frames of each 8 second format. The 78 minor frames are organized as three blocks of 650 words as follows (representing one scan of the instrument):
36 spare words
540 words of Earth view pixel data
(90 x (5 channels + shaft position at mid-pixel))
26 words of housekeeping data
48 words of space view and target view data
(2 x 4 x (5 channels + shaft position))
This structure is maintained for all modes. In static modes, all pixel data locations contain the pixel data for the current antenna position.
The AMSU-B digital format is synchronized to the 8 second synchronization pulse. During each minor frame, 25 words of data are available in the PEU O/P FIFO within 16.7 milliseconds of the start of the minor frame (except in minor frames 1 and 80). Table 4.1.4.3-1 shows the AMSU-B digital data format.
Word Length: 16 bits
Serial Output: 25 - 16 bit words per 100 msec (MSB first)

| Notes: 1. The format consists of minor frames (1 to 80). Minor frames 1 and 80 are blank. This means that no data is available in the PEU output FIFO for reading by the AIP and therefore the AIP should not send any sample pulses to AMSU-B during these minor frame periods. 2. Table 4.1.4.3-2 indicates the meanings for the variables used in Table 4.1.4.3-1. 3. The format structure and definition is identical for all modes. In scanning modes, n, Sn and Tn represent pixel identification. In static modes, n, Sn and Tn have no meaning; all data values relate to the IFOV. |

The Microwave Humidity Sounder (MHS) instrument replaced the AMSU-B instrument on NOAA-N and -P. Scientifically, the MHS is very similar to the AMSU-B instrument, but the manner in which the data are output is quite different. The equivalent of "Digital" data on AMSU-B is referred to as "science data telemetry", or just "science data", for the MHS instrument and comes packaged in a "science data telemetry packet" or "Science Packet" (SCI PKT) for short.
The NOAA-N,P MHS instrument science data will be delayed by two scan lines (or 5 2/3 seconds). The operational Level 1b data accounts for the delay and provides correct geo-location information. The delay, however, is not accounted for in the HRPT broadcast. The two scan line delay is caused by data buffering within the MHS instrument and the spacecraft data handling subsystem.
Consultative Committee for Space Data Systems (CCSDS) is composed of space agencies and industrial associates worldwide, working together to provide well-engineered, standardized solutions for common space data handling needs. The benefits of using CCSDS include: reduced cost, risk and development time, as well as enhanced interoperability and cross-support. For more information on CCSDS, refer to their website at: http://www.ccsds.org/. The data packets for MHS are in CCSDS format (i.e., a primary header, secondary header and checksum).
The MHS instrument, and its associated interface unit (the MIU) on the NOAA satellites, can operate in a variety of different modes and output several different packets, or formats, of data. There are nine different modes for the MHS (see Table 4.1.4.4-1 for details). In addition, all the MHS output must be funneled through a new processor, the MHS Interface Unit (MIU), which may ignore the MHS data completely and output its own telemetry instead. Depending on what mode the MIU is in, different information will be output. For purposes of this Users Guide, only the modes in which MHS data are output will be documented.
| MHS Mode | MHS Output |

| Power-on | Empty Science Data Packet |
| Warm-up | Empty Science Data Packet |
| Standby | Empty Science Data Packet |
| Scan | Science Data Packet |
| Fixed View | Science Data Packet |
| Self-test | Extended Test Data Packet |

To determine what mode the MIU is in, the user must look at word 6 and the first half of word 7 of the AIP minor frame (see Table 4.1.5.2-1). If the MHS instrument is in bootstrap mode, then word 6 and the first 4 bits of word 7 contain three constant bit patterns (2 sync codes and an ID). Otherwise, the mode is found in bits 2-4 of word 6 (see Table 4.1.4.4-2), with one caveat. If the "TIP engineering frame enabled" flag (bit 5 of word 6) is set (1), then ignore bits 2-4. The MIU is in TIP engineering mode and these bits have no meaning. If the MIU is not in TIP engineering mode, then bits 2-4 of word 6 should be used.
There are MIU/MHS data in bytes 6-7 of each minor frame as well as bytes 48-97 (the normal MHS data, when available), bytes 98-101 and byte 205. Sections 4.1.5.1 and 4.1.5.2 contain the formats of the AIP minor frame, while Sections 4.3.3.1 and 4.3.3.2 contain the formats of the minor frame for TIP.
The MHS instrument only interfaces to the MIU box. The MIU interfaces to the rest of the NOAA-N, P spacecraft through the TIROS Command and Control Subsystem (CCS), the TIROS Data Handling Subsystem (DHS) and the TIROS Electrical Power Subsystem (EPS).
The EPS portion interfacing to the MIU is the Power Subsystem Electronics (PSE) consisting of the 28 v Bus Main, Pulse Load, and Survival Buses. All power is distributed to the MHS through the MIU. The AMSU Information Processor (AIP), the Cross-Strapping Unit (XSU) and the TIROS Information Processor (TIP) boxes comprise the DHS part, while the Control Interface Unit (CIU) is the CCS interface portion of the MIU unit. All of these boxes utilize legacy bus architecture interfaces to the MIU while the MIU implements a MIL-STD-1553B redundant interface to the MHS instrument. A single 1553 bus is used for commanding (CMD), housekeeping (HK) telemetry and for science (SCI) data telemetry packets between the MHS and the MIU. However, the MIU, being the bus controller, determines whether the primary or redundant 1553 bus is utilized. Other than the 1553 bus, there is no redundancy in the MIU. The MHS is redundant internally, having both A and B sides to its electronics. The MIU supplies telemetry (MHS and MIU) to the ground during all operational modes. It also provides MHS survival temperature telemetry to the TIP even when the MHS and MIU are not powered.
The AIP provides a serial data stream from the spacecraft, which may be transmitted to the ground or embedded into other composite data streams. Within the AIP data, information is collected from the TIP, AMSU-A1, AMSU-A2, and the MIU. The TIP controls the basic data frame timing, generating a minor frame every tenth of a second (in Orbit Mode) and repeating the entire sequence every 32 seconds, called a major frame. The AIP is synchronized to the TIP timing using the 32-second major frame synch, and the harmonically related one-tenth second (10 Hz) pulse. The AIP itself has an 8-second major frame, which means it repeats its sequence four times during a TIP major frame.
Since the TIP and AIP minor frames are both 10 Hz, they are locked together, using the TIP synch timing. The TIP 32-second major frame pulse synchronizes the AIP. AIP generates its own 8-second timing, but since that period is harmonically related, it will not drift significantly from the 32-second pulse. AIP keeps the data from the AMSU's and MIU synchronized by passing on the timing pulses as appropriate.
The AIP stores the data from all four inputs in serial buffers during one minor frame, and sequences it into the data stream in the subsequent frame. This is mechanized using two sets of alternate buffers. AIP will initiate the data transfer with the 10 Hz synch, followed by the appropriate number of word strobes, 56 in the case of the MIU. The synch serves only to define the start of the transfer. The actual timing of the strobes will differ for each data source, and in the case of the MIU may not even be continuous, but it will always follow the synch.
The MIU provides a total of 80 sets of 56 8-bit words, called minor cycles, each of which will be inserted in an AIP minor frame. A minor cycle counter within the MIU keeps track of the frame sequence, and its content is included in the 56-word data sequence. Because of the double buffer arrangement, the MIU minor cycle count may not agree exactly with the AIP minor frame. However, the 8-second synch pulse will ensure that they are sequencing together uniformly, counting the same 80 frames.
The 56-word count is synchronized using the 10 Hz pulse, so that the first word will be transferred by the strobe following the synch. The data from the MHS is partially synchronized to the TIP timing, but the MS-1553 interface bus and MHS scanning mechanics prevent an exact match. Therefore, the MIU receives the MHS data packets, and packages them along with housekeeping telemetry, to produce the 56-word AIP data.
The 10 Hz and the 8-second synch pulses are received at the MIU and applied to the software using two discrete interrupts. Although both signals are intended to be continuous over long periods, a change in system clocking may result in a jump in either one, which causes it to be early or late with respect to previous pulse timing. The MIU is expected to resynchronize itself to the new sequence.
All AIP telemetry includes the Telemetry Frame Header data in words 6-7 of every minor frame. This is the same data and format as in the TIP Telemetry described in Table 4.1.4.4-5. Table 4.1.4.4-2 contains the format of the MIU AIP data for bytes 6-7.

TIROS Information Processor (TIP) telemetry from the MIU is supplied as 8-bits in Byte 102 of each TIP minor frame (this corresponds to AIP minor frame byte 205). Byte 102 (TIP) or byte 205 (AIP) contains the commutated MHS housekeeping telemetry packet. The content of an MHS telemetry packet is essentially a subset of the science data packet. It contains telemetry data, except not as much as is found in a science data packet, but no science data (i.e., no views of earth and the warm and cold targets). The format of the MIU TIP Telemetry Frame (normal, fast dump, slow dump, and bus engineering modes) is given in Table 4.1.4.4-6.

Table 4.1.4.4-7 lists the telemetry packet types that are generated on the Science Data Bus. The lengths listed are as the data comes from the MHS instrument, and include a 12-byte packet header and 2-byte packet trailer. The MIU strips off these 14 bytes of packet header and trailer, sending the remaining bytes to the AIP to be placed into the minor frames.
| Packet Type | Total Packet Length (octets) |
|---|---|
| Science Data Packet | 1300 |
| Extended Memory Data Packet (EMDP) | 1042 |
| Extended Test Data Packet (ETDP) | 1300 |
The detailed structure of the Source Data field is given in the following sections.
Table 4.1.4.4-8 shows the fields that the Science Data Packets contain.
| Field Name | Size (Octets) |
|---|---|
| Full Housekeeping Data | 39 |
| Status Word | 1 |
| Signal Processing Status | 9 |
| Pixel Data | 1176 |
| OBCT Temperature Data | 16 |
| Spares | 45 |
The format of the "Full Housekeeping Data" field is described in Table 4.1.4.4-16.
In modes which do not generate Science Data (ie. all modes except Scan Mode and Fixed View Mode), an "Empty Science Data Packet" is generated, in which the remaining fields of the Science Data Packet (i.e., "Status Word" through "Spares") are undefined.
The format of the spares field is unallocated at present. All octets will be set to "00".
Table 4.1.4.4-9 shows the format of the Status Word.

| DC Offset Valid | Scan Control Valid | Profile | Unused | ||||
The "DC Offset Valid" bit is set to a "1" when all channels calibration targets readings lie within acceptable limits, as determined by the DC Offset Algorithm. This bit will be set only in Scan Mode when the calibration targets are sampled.
The "Scan Control Valid" bit is set to a "1" if all mid-pixel positions of the reflector during Earth, Space and On-Board Calibration Target (OBCT) views are within the limits for the Scan Mode profile, or within the limits of the requested position in Fixed View Mode. This bit will be set only in Scan Mode or Fixed View Mode.
The "Profile" code is set to:
00 : Profile 0
01 : Profile 1
10 : Profile 2
11 : No Profile calculated (profile will be manually loaded/modified)
It is intended that Profile 0 will define the Nominal Scan Mode Profile with nominal Space View position. Profiles 1 and 2 will nominally be used for the alternate Space view positions. However, any profile can be reprogrammed to another position versus time profile by reloading the Scan Control Table profile parameters.
The format of the Signal Processing Status field is shown in Table 4.1.4.4-10.

The "Valid" bit is set to a "1" when all samples of this channel for this scan revolution lie within the ADC dynamic range.
H1..H5 are the five input channels from the Receiver. The Electronics Equipment (EE) has six signal processing channels, SPE1..SPE6. In the nominal configuration, the Receiver channel is connected to the corresponding EE channel, e.g., H1 to SPE1, and SPE6 is unused.
The SPE Mux Code is used to identify which Receiver channel, if any, is connected to the EE redundant channel, as shown in Table 4.1.4.4-11.
| SPE MUX Code | Configuration |
|---|---|
| 000 | H1 to SPE 6 |
| 001 | H2 to SPE 6 |

The Science Data field can be separated into Earth, Space and OBCT View Data fields, which all follow a common format. They are differentiated only by the source of the data that is written to them. The fields are arranged as shown in Table 4.1.4.4-13.
| Field name | Number of Pixel subfields |
|---|---|
| Earth | 90 |
| Space | 4 |
| OBCT | 4 |
In Fixed View Mode, the Science Data Packet is the same format as Scan Mode, but the concept of Earth, Space and OBCT pixels does not apply. All 98 pixels are for the fixed view position. The (90 + 4 + 4) pixels are however collected with the same timing as though Scan Mode were performed.
Each of the Pixel sub-fields contain a position and five pixel values. The format of a Pixel Subfield is shown in Table 4.1.4.4-14.

The "Mid-pixel position" data is the angular position of the Reflector at the mid-point of the pixel integration period defined by:
The OBCT Temperature Data field contains the On-Board Calibration Target high precision temperature parameters. The format of this block is given in Table 4.1.4.4-15.

The full Housekeeping Telemetry Data blocks contain the following fields as shown in Table 4.1.4.4-16.
| Field Name | Size (Octets) |
|---|---|
| Mode and Subcommutation Code | 1 |
| Telecommand Acknowledgment and Fault Code | 5 |
| Switch Status | 3 |
| Temperature Data | 24 |
| Raw Current Consumption Data | 6 |
The Sub-Commutation code is not significant for the Science Data packet as all telemetry is returned.
As with other packets, the Mode Code identifies the packet as either a Science Data Packet (Scan and Fixed View Modes), an Extended Test Packet (self-test mode), an Extended Memory Data Packet (Mode Code = "1111") or an Empty Science Data Packet (all other Modes).
Note that the Telecommand Acknowledgement field of Science Data packets provides acknowledgement of commands received on the Science Data Bus. (Commands on the Command/telemetry Bus are acknowledged in HK Telemetry Packets.)
The Temperature Data Field of each packet will contain all twenty-four thermistor telemetry channel parameters, instead of the multiplexed four of the Housekeeping telemetry packet. The OBCT temperatures are not contained here, as all such values are allocated a separate field in the Science Data Bus.
The Raw Current Consumption Data Field is the internal PSU Current analog telemetry as defined in Table 4.1.4.4-17.
| MSB | LSB | ||||||

The spacecraft's AMSU Instrument Processor (AIP) collects digital data from the AMSU-A, AMSU-B (NOAA KLM), and MHS/MIU (NOAA-N, -P) sensors. This data consists of earth view pixel data, housekeeping data and space and blackbody view data.
Figure 4.1.5.1-1 shows the AIP telemetry word location in the frame format, and Table 4.1.5.1-1 contains AIP telemetry word titles, locations within the frame, and word descriptions in tabular form.
