Demonstrate GNSS reflectometry at low grazing angles for altimetry for sea ice detection using a new software-defined GNSS receiver.

Description

Demonstrate the technique of GNSS Reflectometry at low grazing angles for altimetry (primarily for sea ice detection) using a new software-defined GNSS receiver. Additionally, a miniaturised radiation dosimeter will also be tested in flight. System for so-called passive reflectometry, among other things, which allows for measurements of height to be carried out in the decimetre and centimetre range,

PRETTY hosts two payloads for environmental monitoring: a GNSS-Reflectometer to determine various geophysical properties (sea-surface height, sea-surface roughness, wind speed, etc.) and a dosimeter to assess the space radiation environment and its effects on electronics. The GNSS-Reflectometer operates on the L5 frequency and implements both the interferometric approach (iGNSS-R) and the clean-replica approach (cGNSS-R). The dosimeter payload is SATDOS-1, a stand-alone dosimeter payload for nanosatellites which provides total ionizing dose (TID) and single event effect (SEE) assessment in orbit.
