From GPS Receiver to GNSS Reflectometry Payload Development for the Triton Satellite Mission
Remote Sensing, 2021 The global positioning system (GPS) receiver has been one of the most important navigation systems for more than two decades. Although the GPS system was originally designed for near-Earth navigation, currently it is widely used in highly dynamic ...

Effective Surface Roughness Impact in Polarimetric GNSS-R Soil Moisture Retrievals
Remote Sensing, 2023 Single-pass soil moisture retrieval has been a key objective of Global Navigation Satellite System-Reflectometry (GNSS-R) for the last decade. Achieving this goal will allow small satellites with GNSS-R payloads to perform such retrievals at high ...

Software tools for GNSS interferometric reflectometry (GNSS-IR) [PDF]
GPS Solutions, 2018 GNSS-R interferometric reflectometry (also known as GNSS-IR, or GPS-IR for GPS signals) is a technique that uses data from geodetic-quality GNSS instruments for sensing the near-field environment. In contrast to positioning, atmospheric, and timing applications of GNSS, GNSS-IR uses the signal-to-noise ratio (SNR) data.
