NOAA KLM User's Guide
The Data Collection System (DCS) on the NOAA KLM spacecraft is provided by CNES of France. This system provides a means to collect data and/or locate fixed and mobile buoy and balloon platforms. A complete description of the system is contained in Section 3.6.
If the data platforms and receive site are simultaneously in the view of the satellite, the Data Collection System provides the immediate rebroadcast of data from the platform, received by the satellite via an UHF uplink. These data are included as 32 8-bit words in the TIP minor frame. As such, it is available in both the low data rate DSB and high data rate HRPT services. Since the data rate on the new DCS/2 instrument has been increased from 1200 to 2560 bps, the number of TIP words allocated to DCS has been increased to 32 from the previous spacecraft series. However, interpretation of the telemetry remains unchanged. The DCS data in the direct broadcast services will only permit platform location computations with the proper computer software. More details can be obtained from Service ARGOS, as noted in Appendix E.
