UGM ground station requires a satellite tracking control system that can follow the movements of the satellite. The system proposed in this study is relying on the calculation of Two Line Elements (TLE), the reason is that the data TLE has a subtle error. The compass sensor is used to ensure accuracy; the results were [...]

Abstract
Field Programmable Gate Array (FPGA) is susceptible from hazardous radiation that leads to be in error state. In order to avoid that condition, we apply a fault tolerance technique. Most of the fault tolerances today are only using one mode, mean the fault tolerance that is applied will run all of the time without any [...]

Hazard radiation can lead the system fault therefore Fault Tolerance is required. Fault Tolerant is a system, which is designed to keep operations running, despite the degradation in the specific module is happening. Many fault tolerances have been developed to handle the problem, to find the most robust and efficient in the possible technology. This [...]
