METHOD OF DETERMINING PARAMETERS OF ARTIFICIAL SATELLITE ORBIT OF THE EARTH Russian patent published in 2018 - IPC G01S5/00 

FIELD: astronautics.

SUBSTANCE: invention relates to the field of cosmonautics, namely to technique of performing trajectory measurements and determining the parameters of the orbit of an artificial earth satellite (AES), and can be used on ground and airborne flight control complexes to accurately determine the current parameters of satellite motion. This result is achieved by using a ground-based radio-technical station (GRTS) located at a position with known coordinates x_K, y_K, z_K, and N ≥ 2 radiating benchmark stations (RBS) located at positions with known coordinates where n = 1…N is the number of the RBS, and the method is based on the emission of test radio signals from the GRTS at the middle frequency ƒ₀ and N RBS of medium-frequency ƒ_n at time t₀ and the subsequent reception of these test radio signals after retransmission of the satellite by means of GRTS at time instants and at medium frequencies and respectively, and is also based on the measurement of the inclined ranges from the satellite to GRTS R_SK and before each of the N RBS , on the calculation of the satellite coordinates x₀, y₀, z₀ according to the known coordinates of the GRTS, the known N coordinates of the N RBS and the measured oblique distances R_sk, and , the calculation of the orthogonal components of the velocity vector of the satellite according to the known coordinates of GRTS, known N coordinates of RBS, the calculated coordinates of satellite x₀, y₀, z₀, the values of the mean frequencies transmitted ƒ₀, ƒ_n and adopted test radio signals, a preset frequency of shift ƒ_G operating frequency of satellite, and as the parameters of the satellite orbit, the set of satellite coordinates x₀, y₀, z₀ and the orthogonal components of its velocity vector at time t₀.

EFFECT: technical result is high speed of operation.
