This is a list of satellites in geosynchronous orbit (GSO). These satellites are commonly used for communication purposes, such as radio and television networks, back-haul, and direct broadcast. Traditional global navigation systems do not use geosynchronous satellites, but some SBAS navigation satellites do.

SBUDNIC was launched to test Arduino Nano and other commercial off-the-shelf technology in space, using a simple, open-source design. [2]An ambitious project is the QB50, an international network of 50 CubeSats for multi-point by different universities and other teams, in-situ measurements in the lower thermosphere (90–350 km) and re-entry research.
