N2 - The omnipresence global navigation satellite system (GNSS) signals have not only provided high accuracy navigation but also encouraged several remote sensing missions. In a GNSS reflectometry (GNSS-R) mission, the reflected signals are processed to form delay Doppler maps (DDMs) so that the properties including roughness, ocean wind speed, and soil moisture can be retrieved. NCKU is developing the primary payload, GNSS-R receiver, for the National Space Organization TRITON GNSS-R mission. The TRITON GNSS-R payload distinguishes from other GNSS-R receivers in its capability in processing multi GNSS signals, generating 2x DDMs, and providing finer resolution in observation. As a result, the observables may render better retrieval results in the estimation of ocean wind speed and other remote sensing variables. The GNSS-R payload that is developed has undergone several flight tests and the functionality and performance are verified. The TRITON satellite is scheduled to be launched in late 2022.
