Embodiment Construction

[0040] A satellite navigation multi-beam anti-jamming test method, comprising the steps of:

[0041] Step 1: Set up the test environment

[0042] Establish a test darkroom, and set a three-axis rotating device in the middle of the darkroom. The rotating device is used to place the satellite receiving antenna, and the satellite receiving antenna is also connected with the satellite positioning and navigation equipment; the satellite receiving antenna, satellite positioning and navigation equipment together constitute the tested Equipment; set up a data transmitting device in the dark room, the data transmitting device simulates a satellite in the sky, the number of data transmitting devices is not less than 8, and the PDOP value is not greater than 4. When setting, establish the space coordinates based on the satellite receiving antenna, and ensure that There is at least one data transmitting device north of the equator. When the data transmitting device simulates the RNSS type...

Abstract

The invention belongs to a test method, and particularly relates to a satellite navigation multi-beam anti-interference test method. The satellite navigation multi-beam anti-interference test method comprises the following steps that step one: the test environment is set; step two: fixed beam testing is performed; and step three: beam tracking testing is performed. The effects of the satellite navigation multi-beam anti-interference test method are that (1) testing of both satellite navigation multi-beam pointing and anti-interference performance can be realized: one time of scene setting is performed in a dark room, and fixed beam testing, beam tracking testing and anti-interference performance testing are performed by controlling the number of satellite signals emitted by a satellite constellation simulator so that testing of both satellite navigation multi-beam pointing and anti-interference performance can be realized.

Description

technical field [0001] The invention belongs to testing methods, in particular to a satellite navigation multi-beam anti-jamming testing method. Background technique [0002] The satellite navigation signal arriving at the satellite user terminal is extremely weak and susceptible to intentional or unintentional interference. In order to improve the adaptability of satellite user terminals to complex electromagnetic environments, the militaries of various countries have put forward clear requirements for the anti-jamming capability of satellite user terminals. [0003] In recent years, domestic satellite navigation equipment has developed rapidly in anti-jamming technologies such as adaptive zeroing, beamforming, and inertial assistance. Into the engineering development stage. In the development process of satellite navigation equipment, it is necessary to design anti-jamming performance test methods according to the characteristics of anti-jamming technology, and to test a...
