Myriade
Myriade is a European miniaturized satellite platform developed by EADS Astrium and CNES. EADS Astrium offers the Myriade bus under the commercial name Astrosat-100. CNES began developing Myriade in 1998, as a continuation of the Proteus program. Description. Myriade satellites are cube-shaped, measuring 60 cm along one side, and weigh between 100 and 200 kg. The control system is a Transputer T805 with 1 Gigabit of memory and capable of 5 MIPS. It is interfaced via i2c to FPGA and PIC microcontrollers that control onboard equipment. Power is provided by one steerable gallium arsenide solar array. Communication is  by two S band transceivers, offering downlink rates of up to 400 kbit/s, and an optional X band system with downlink rates of 18-72 Mbit/s. Launched Myriade satellites. The first Myriade based system was Demeter (Detection of Electro-Magnetic Emissions Transmitted from Earthquake Regions), launched in June 2004. Since then, missions have included:
