US: Engineering students at the Cornell University have designed a nanosatellite to help calibrate GPS with pinpoint accuracy. The nanosatellite is called CUSat. It will be launched on 14 September from the Vandenberg Air Force Base in Lompoc, California.
The CUSat Satellite Project has been going on for eight years. It has won the University Nanosat-4 Program, which is aimed at educating future satellite engineers. CUSat weighs about 90 pounds. Once in space, the CUSat will move into low orbit to help calibrate GPS accuracy to within 3 millimetres. CUSat is also equipped with a camera for Earth observation. It will be launched on a SpaceX Falcon 9 rocket.
