Software Engineering of LAPAN Satellite Autonomous Operation and Control

The number of passes will be a significant consequence for the operation of LAPAN A-2 satellites that have near-equatorial orbit. This is beneficial for mission operations, but also a challenge for the satellite operator to regulate the process of monitoring, control and data acquisition. Repetitive process of monitoring, control and data acquisition would be more efficient if it is done automatically. This paper will discuss the design, implementation and testing of LAPAN satellite system software automation. Requirements-based software design has been carried out and implemented starting from the level of modules up to the system level. Software testing results indicate there are 2 seconds differences in the performance of a data processing satellite telemetry already in orbit compare to test in the laboratory for 112 bytes telemetry data. As for the size of 213 bytes of data there is a difference of 3 seconds.
