1.0 Introduction to the NOAA KLM System

The National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA) jointly administer the civilian polar orbiting spacecraft system for the United States. Upon successful achievement of orbit, NASA conducts an engineering evaluation and checkout of each satellite. During the instrument turn-on checkout period, the NASA team directs the satellite, and obtains and analyzes engineering data necessary to the evaluation. Upon completion of testing, the satellite is turned over to NOAA for routine operational control.

In the Spring of 1998, a new series of NOAA Polar Operational Environmental Satellites (POES) commenced with the launch of NOAA-K. NOAA-K and its immediate successors, NOAA-L and NOAA-M, represent an improvement over the previous series of satellites that began with TIROS-N (launched in October 1978), and continued with NOAA-6 through NOAA-14 (launched in December 1994).

The launch of NOAA-K POES has mandated the existence of this document. In order to eliminate redundancy for NOAA's polar orbiter customers, it has been decided that the NOAA Polar Orbiter Data User's Guide, the NOAA Technical Memorandum NESS 95 (The TIROS-N, NOAA A-G Satellite Series), the NOAA Technical Memorandum NESS 107 (Data Extraction and Calibration of TIROS-N/NOAA Radiometers) and the TIROS-N Series Direct Readout Services Users Guide would be combined into one document. The contents of this document (NOAA KLM User's Guide) includes an introduction to the NOAA-K, -L, -M system (henceforth, referred to in this document as NOAA KLM), descriptions of the spacecraft characteristics, orbital considerations, sensor package, real-time data systems for local users, tracking procedures to acquire data from real-time transmission systems sensors, ingest and preprocessing, calibration, and formats for Level 1b data and Operational products.
