The Doppler measurements of the telemetry radio signals nanosatellite CubeBel-l for a single pass over the Belarusian State University ground station were carried out. Two methods for orbit determination of a small satellite are considered. The first method is based on the SGP4 model and requires additional information from the NORAD TLE catalog of the satellite orbital parameters. An unknown small satellite is identified using the NORAD TLE catalog based on a probabilistic estimation of the elevation angle and the Doppler frequency shift of receiving telemetry signals. The second method is based on processing experimental measurements of the Doppler frequency of the telemetry radio signals and Keplerian circular motion model for the small satellite. It does not require additional information from the NORAD database of satellite orbital parameters.
