GNSS-R Workshop – May 2018

GNSS-R Workshop

Advances in Earth Observation with GNSS Reflectometry from space: TechDemoSat-1 User Workshop and ESA TGScatt Presentation

The UK TechDemoSat-1 (TDS-1) satellite was launched in July 2014 and carries the first GNSS Reflectometry (GNSS-R) instrument able to measure ocean surface winds globally and routinely using reflected signals of opportunity from Global Navigation Satellite Systems (e.g. GPS). The TDS-1 GNSS-R receiver is a precursor of the NASA CYGNSS constellation of microsatellites launched in December 2016 to monitor hurricanes.

This workshop was held at The National Oceanography Centre in Southampton, UK, on Thursday 24th May 2018. The current status of TDS-1 and GNSS-R wind products on MERRByS were presented, the latest findings from the TGScatt study about ocean wind retrieval, validation and impact were discussed, and recent results from CYGNSS and other applications of GNSS-R for Earth Observation were presented.
