3-axis micro-accelerometer for measuring non-gravitational forces, accurate to about 10−11 ms−2
MIMOSA (Micromeasurements of Satellite Acceleration), COSPAR 2003-031B, was a Czech scientific microsatellite. The satellite was nearly spherical with 28 sides and carried a microaccelerometer to monitor the atmospheric density profile by sensing the atmospheric drag on the approximated sphere.[1]
MIMOSA was launched on June 30, 2003, alongside other miniature satellites including MOST and several CubeSat-based satellites. It had a fairly eccentric orbit, with an initial perigee of 320 km (200 mi) and apogee of 845 km (525 mi).[failed verification][2] The satellite never became fully functional due to several technical problems on board.[3] It is no longer in orbit. NORAD reported it burnt into the atmosphere on December 11, 2011.[4]
