Multi-constellation, dual-polarization, and dual-frequency GNSS-R stratospheric balloon experiment over boreal forests

Scientific evaluation of the
³
Cat-2 payload (PYCARO reflectometer) has been performed from the BEXUS 19 stratospheric balloon flight with an apogee of ~ 27,000 m over boreal forests and lakes. The payload was configured in closed-loop mode during this flight. Results show the first-ever multi-constellation Global Navigation Satellite Systems Reflectometry (GNSS-R) measurements at dual-band and dual-polarization.
