Abstract

The project proposal is the development and production of a prototype of a digital subsystem of telemetry and remote control for satellites. This is a essential equipment in a satellite, and it is a mandatory embedded subsystem for all satellites to be send into space. So it's a critical equipment for any mission and its survival in space implies the survival of all space mission. The idea of the development is to implement the complete Intermediate Frequency section (IF) of a TMTC transponder with a reconfigurable microprocessor with a FPGA (in the same DIE). On the FPGA (Processing Unit - PU) will be performed every sampling and processing in baseband, modulation and demodulation. On the processor (Control Unit - CU will be performed the housekeeping of the subsystem. The processing unit will be fully developed by the company and described in hardware language (Verilog Hardware Description VHLD-Language). The processor is a 32 bit SPARC V8 high performance and low power consumption, that could be space qualified. The prototype will be developed with a commercial version of the mentioned FPGA. This microprocessor and associated components are free of import restrictions such as ITAR. Using this reconfigurable microprocessor will offer great flexibility to the machine and can be used in different types of space missions. The company is already working on a development of a TMTC subsystem with analog components, with internal financing. From this internal developing became necessary the digital data processing and also the development of a new modern equipment, comparable to those available in major space markets such as United States and Europe. At the end of this project there will be a working prototype of the entire subsystem ready to go to to the space qualification model project. A very simple Front-End will be developed with COTS to allow the test of the subsystem. (AU)
