Navigation antenna layout method suitable for dual-side-looking work remote sensing satellite

Abstract

The invention discloses a navigation antenna layout method suitable for a dual-side-looking work remote sensing satellite. The method includes the following steps that 1, according to the configuration layout space constraint of the dual-side-looking work remote sensing satellite, by means of whole satellite three-dimensional model analysis, available single-machine layout space on the outer side of a satellite body is found, and the position of the available layout space least shielded by a single machine is determined; 2, capture satellite number simulation analysis of navigation antennas is developed according to the performance of the navigation antennas and the available space position, and the optimal direction of the navigation antennas in satellite body layout positions is determined according to the simulation result. The problem about the navigation antenna layout of the dual-side-looking work remote sensing satellite is solved, the number of the navigation satellites can be captured by increasing available effective view fields and in-orbits of the navigation antennas in a common work mode, therefore, the positioning and speed measuring precision of the satellite in-orbits is improved, measuring errors of satellite in-orbit running rails are reduced, and a solid foundation is laid for high-definition imaging of load antennas.

Description

technical field [0001] The invention relates to the technical field of satellite overall design, in particular to a layout method for remote sensing satellite navigation antennas suitable for double-side-view work. Background technique [0002] With the rapid development of satellite technology, improving the quality of high-resolution imaging has become an urgent problem for satellite models. Remote sensing satellite imaging needs to eliminate the influence of orbit measurement errors. Generally, satellites fly in orbit in a side-view working mode, and the imaging resolution The rate is relatively low. At this time, the use of ground or on-board measurement methods can solve the influence of satellite orbit measurement errors. For the impact on positioning, ground imaging processing directly uses high-precision navigation orbit measurement data. The accuracy of navigation orbit measurement data largely depends on the effective field of view of the navigation antenna and th...
