Data Description

    IJPS Companion File - There are two types of Initial Joint Polar-orbiting Operational Satellite (IJPS) System Companion files: 1. NOAA AIP 1a telemetry file - contains the AIP minor frame data as generated on-board the satellite for the orbit. An AIP minor frame contains packed, or commutated, instrument data and other satellite data covering a time period of 0.1 seconds. 2. IJPS Ancillary file - a tar file that contains all of the ancillary input files required by the preprocessor in order to identically reproduce its output (e.g., the 1b* data sets). These files include instrument-level 1a files, control files, navigation-related files, and calibration-related files.
