Myriade

In today's world, Myriade is a topic of great relevance and interest to a wide spectrum of society. As time has passed, Myriade has gained increasing importance in various fields, from politics to popular culture. In this article, we will thoroughly explore the impact and relevance of Myriade, analyzing its implications in everyday life, its evolution over the years and its influence in different areas of study. From its origins to the present, Myriade has been the subject of debate and reflection, and it is crucial to understand its importance in the current context. Therefore, it is essential to delve into this analysis to fully understand this topic that is so relevant today.

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:

  • PARASOL, a French-built Earth observing research satellite - launched in December 2004.
  • Essaim, a French military reconnaissance microsatellite constellation - launched in December 2004.
  • Spirale, a demonstrator system which includes two 120 kilograms (260 lb) microsatellites - launched in February 2009.
  • Picard, dedicated to the simultaneous measurement of the absolute total and spectral solar irradiance, the diameter and solar shape, and to probing the Sun's interior - launched in June 2010.
  • ELISA : ELISA 1, ELISA 2, ELISA 3 and ELISA 4 are a suite of French military satellites - launched on December 17, 2011.
  • MICROSCOPE, ministallite designed to test the weak equivalence principle to two orders of magnitude better than can be achieved by ground-based experiments.[1][needs update] Launched in 25 April 2016.
  • TARANIS,[2][3][4] launched in November 2020 but experienced launch failure (due to rocket) and did not achieve orbit.
