Test inter-satellite communication and multiple other technologies.

Description

GAMALINK, which is an S-band inter-satellite communication module, a novel dual band GPS/BD receiver, an AIS receiver, and an ADS-B receiver, all being designed based on SDR technologies. Also a novel cold-gas micro propulsion module based on MEMS technology will be used for orbit and constellation control.

TW-1 project consists of three CubeSats carrying different payloads and instruments with one 3U CubeSat and two 2U CubeSats, forming an along-trace satellite network and/or constellation. CubeSats networking based on Gamalink.

Monitoring sea ice and gaining the maritime traffic information in polar region based on AIS receiver and camera. Demonstration of autonomous formation flying including the along-track orbital (ATO) formation and the projected circular orbital (PCO) formation. In-orbit demonstration and validation of ADS-B receiver/ Gamalink / Micro-propulsion. Imaging the satellite separating process.
