Microaccelerometers from VZLU are in orbit

On Friday, 22 November 2013 was launched the rocket Rokot from russian Pleseck Cosmodrome, which delivered a trio of European SWARM satellites to orbit. Satellites developed by EADS Astrium GmbH for the European Space Agency ( ESA), are designed to measure the Earth's magnetic field. For this purpose, they have unusual trapezoidal shape with a nine-extendable pole that pops up after reaching orbit. The three SWARM satellites are identical and will circulate around the earth polar orbit of 460 to 530 kilometers above the Earth's surface. Two of the satellites eventually come down to run 300 miles above the earth. Mission Swarm can help improve the accuracy of navigation systems or earthquake prediction. It can also help, for example, when examining ocean currents or prospecting.

The development of scientific instruments placed in the satellite participated in fifteen Czech consortium of companies led by VZLU. Each of the satellites has on board Czech microaccelerometer for measuring very small and slow acceleration, which affect the movement of the satellite. Microaccelerometer help determine the effect of non-gravitational forces on the motion of artificial satellites in orbit around the Earth. This eliminates the possible bias in the measurement of the magnetic field.

For VZLU is a culmination of great effort . VZLU deals with Space mission SWARM since 2005, when the project of the development of new micro-accelerometers started. In total were made three flight pieces and one engineering model to be tested on a Russian spacecraft Universat-2. The mission SWARM creates a new generation of micro-accelerometers. Previous types of devices have been tested along with the national project on the Russian satellite Resurs (1992), on the U.S. Space Shuttle Atlantis (STS -79, 1996) and even on the Czech satellite MIMOSA (2003).
