There is an increasing demand world over for launch services for small satellites. The Small Satellite Launch Vehicle (SSLV) of the Indian Space Research Organization (ISRO) is developed for the purpose of on-demand launching of small satellites to low earth orbit in a fast turn-around mode. The avionics system for SSLV thus needs to be low cost, miniaturized and simpler in architecture, making it amenable to mass production and fast integration. The telemetry system for SSLV is developed with a view to acquire the launch vehicle performance parameters and provide a formatted, serialized telemetry data. Low cost industrial grade, low form factor state of the art electronic components, with high level of functional integration, is used in the subsystem designs. The designs also implement processing in re-programmable Field Programmable Gate Arrays (FPGA) and use indigenous components wherever available to mitigate obsolescence-related issues. The miniaturized telemetry system has flown successfully in two missions. The flight data is analyzed and the performance of the system is normal. The new system provides a considerable reduction in size, mass, power and cost compared to the telemetry systems used in conventional launch vehicles without sacrificing the stringent performance and reliability requirements of aerospace application. This makes it a suitable candidate for future space missions like Reusable Launch Vehicle (RLV) and inter-planetary missions.
