AbstractOperational experience of the Landsat 1 spacecraft pointed out the need for additional on-board command storage. Landsat 2 was launched on January 22, 1975 with a general purpose computer programmed for command storage and spacecraft "monitor and reaction" tasks. The computer, software, and its I/O interface to the spacecraft, called ERTS Command Auxiliary Memory (ECAM), was designed to supplement the existing command subsystem. The computer selected for the task was the Advanced On-Board Processor (AOP) which has subsequently been designated the NASA Standard Spacecraft Computer.
