Abstract

The invention discloses an SLR station three-dimensional coordinate geometric solution method based on low-orbit satellite satellite-borne GNSS technology. According to the geometric solution method,a GNSS receiver mounted on a low-orbit satellite is used to perform continuous tracking observation, and an undifferenced method is used to perform a precise kinematic orbit determination for the low-orbit satellite; then a satellite laser ranging rangle reflection prism carried in the low-orbit satellite is used to obtain an SLR laser ranging value, the system error correction is carried out on an SLR observation material, the material is converted into a distance between a high precision SLR station and a centroid of the low-orbit satellite, and combined with a precise geometric orbit of a multi-epoh single or multiple low-orbit satellites, according to the distance intersection positioning principle, the three-dimensional geometric coordinates of the ground SLR observation station are calculated by a least-squares method. The satellite-borne GNSS data and SLR tracking observation data of low-orbit satellites are used, a geometric method is used to realize high-precision geometric coordinates solution of the ground SLR observation station, and the solution has the advantage that a complex dynamics model is avoided compared with a classical dynamics solution.

Description

technical field [0001] The invention relates to a three-dimensional coordinate geometric solution method of an SLR station based on low-orbit satellite-borne GNSS technology. Background technique [0002] Satellite Laser Ranging (SLR) is a two-way ranging method for tracking and observing satellites by measuring the round-trip propagation time of laser pulses between the ground and the satellite. , such as very long baseline interferometry (VLBI), global navigation satellite system (GNSS), satellite Doppler orbit determination and positioning system (DORIS), etc. The main difference. GNSS is a very important space technology that provides precise positioning, navigation and time services on a global or regional scale. GNSS mainly includes GPS in the United States, GLONASS in Russia, and several other emerging global / regional navigation satellite systems, such as Galileo in Europe and Beidou in China. [0003] At present, the space geodetic technology based on VLBI, SLR, GN...
