GomX4 A



GomX-4A (Ulloriaq) and GomX-4B will test intersatellite communication links and propulsion while orbiting up to 4500 km apart. The two satellites are based on the CubeSat models that are nanosatellites based on standardized 10×10 cm units. GomX-4B is a ‘6-unit’ CubeSat, double the size of its predecessor GomX-3, which was released from the International Space Station in 2015. The two small satellites will test intersatellite link technology, routing data from one satellite to the other, then down to the ground station. Part of the ground testing ensured they could indeed talk to each other and the actual ground station on an end-to-end basis.
