Applying Malawi Continuously Operating Reference Stations (CORS) in GNSS Meteorology
South African Journal of Geomatics, 2022 Global Navigation Satellite System (GNSS) signals in the L-band are affected by the non-dispersive neutral atmosphere. Regardless of their center frequency, the L-band code and phase observations are affected by the same measure of delay. GNSS receivers play a significant role in quantifying the zenith tropospheric delay (ZTD) from satellite signals ...
