An Accuracy Prediction of OBC System Reset LAPAN-A3/LAPAN-IPB Satellite

Currently LAPAN has launched three A-series
satellites which are still in orbit. One of them is LAPAN-A3/LAPAN-IPB satellite that has various missions, such as earth observation using multispectral camera and digital space camera, global maritime awareness support using AIS receiver, and scientific mission using magnetometer. With these various kinds of complex missions, reliability are needed for all satellite subsystems and operation. OBC is one of the subsystems that has a role as satellites brain. On LAPAN-A3/LAPAN-IPB satellite, it equipped with fault tolerant system in form of external reset system to keep it reliability. When the reset occurs, all subsystems will be restored to the initial setup, therefore all operators must know when it will happen in order to anticipate that condition to keep all satellites mission operations continues. The accuracy of LAPAN-A3/LAPAN�IPB satellite OBC’s reset system time prediction will be analyzed using LAPAN-A3/LAPAN-IPB satellite log files in this paper. Based on the analysis of log files data, it is known that the OBC’s reset system time prediction is 37 seconds slower than the actual reset system time.
