The next generation of nanosatellites in GomSpace has been developed after the success of GOMX-3 in aircraft traffic monitoring and L-band communications. GOMX-4 is the demonstration mission of this new 6U platform including two satellites; GOMX-4A and GOMX-4B, which are mainly intended to test constellation capabilities for orbital control and inter-satellite communications together with additional innovative technologies. GOMX-4B is funded by ESA for In-Orbit Demonstration (IOD) purposes demonstrating the 5 payloads on-board: the 6U propulsion module from NanoSpace; the innovative Inter-Satellite Link (ISL) from GomSpace; the Chimera board developed by ESA; the HyperScout Hyperspectral Camera from Cosine and the Star Tracker from ISIS. GOMX-4A is a satellite to monitor Greenland and the artic region by capturing ADS-B, AIS and images for the Danish Defense Acquisition and Logistics Organization (DALO). The numerous in-orbit experiments and various payloads included in the GOMX-4 mission show the high performance and flexibility of the GomSpace 6U platform, flying its advanced EPS and its AOCS for the first time. The two satellites were launched on the 2nd of February 2018 on a LM-2D. The in-orbit results presented here show the extensive capabilities of these innovative nanosatellites, and opens the path for scaling to larger platforms and advanced constellations with compact communication and optical payloads.
