Paper Title
In Orbit Re-Programmability of Digital Subsystems of Satellite
Abstract
Every Spacecraft/ Satellite has many digital subsystems which are widely used for a various kind of controlling and data processing applications. Field Programmable gate arrays are one of the most common elements of these subsystems considering the last minute programmability. Presently, One Time Programmable (OTP) and SRAM based FPGAs are used in the space programs. Once the functionality of FPGA is fixed at ground, then it cannot be altered in space. Re-Programmability of these devices would be useful to fix the bugs, change the functionalities or addition of the new functionalities in due time course resulting in extension of mission life. Here in this project the concept of the full Re-Programmability and partial Re-Programmability of SRAM based FPGA as a part of the satellite or space craft would be demonstrated. The concept of Re Programmability of FPGA devices in orbit is achieved using rewritable program memory, re programmable rad-hard FPGA devices and a self developed unique protocol as part of the main logic/program.
