3Cat 2

3Cat 2 [UPC]

3Cat 2 is a 6U CubeSat developed at the Universidad Politécnica de Cataluña (UPC) to demonstrate a novel dual frequency (L1+L2) GNSS-R altimeter/scatterometer and GNSS-RO.

The mission is designed to perform ocean altimetry by means of Global Navigation Satellite Systems Reflectometry (GNSS-R). The main payload is the novel dual-band altimeter P(Y) & C/A ReflectOmeter (PYCARO) which has been designed and manufactured at UPC’s Remote Sensing Lab and NanoSat Lab. It also integrates the Mirabilis Star Tracker, an experimental star tracker for attitude determination and the AMR eLISA magnetometer designed and manufactured at IEEC for the future ESA’s LISA mission.
