Evaluation of Geometric and Atmospheric Doppler for GNSS-RO Payloads
AUT Journal of Electrical Engineering, 2016 To reduce the sampling rate in global navigation satellite system (GNSS)-radio occultation receivers, it is essential to establish a suitable estimation of Doppler frequency from the received signal in the satellite onboard receiver. This receiver is usually located on low earth orbit satellite and receives GNSS satellites signal in the occultation ...
