Description
The master task interrogates temperature sensors and applies Lockheed-provided algorithms to determine heater-switch positions for the next cycle.
Note: It is the responsibility of LAT FSW to maintain the LAT instrument temperature within a narrow range to benefit the physics analysis (mechanical stability of the instrument and electrical stability of the read-out electronics). It is the responsibility of the spacecraft to maintain the LAT instrument temperature within (much wider) survival limits.
