The invention provides a ground verification system based on a microsatellite navigation system. The ground verification system comprises a non-cooperative small-sized target simulation system and the microsatellite navigation system. The microsatellite navigation system comprises an approaching microsatellite. The non-cooperative small-sized target simulation system is used for simulating the relative movement between the non-cooperative small-sized target simulation system and the approaching microsatellite. The microsatellite navigation system is used for navigating the relative movement between the non-cooperative small-sized target simulation system and the approaching microsatellite. The invention further provides a corresponding method. The non-cooperative small-sized target simulation system comprises an unmanned aerial vehicle, a triaxial cloud deck and a non-cooperative small-sized target simulator. The unmanned aerial vehicle is connected with the non-cooperative small-sized target simulator through the triaxial cloud deck. By the adoption of the ground verification system and method, the advanced unmanned aerial vehicle is adopted, and the relative movement between the approaching microsatellite and a non-cooperative small-sized target can be simulated in a high-precision mode.
Description
technical field [0001] The invention relates to satellite navigation technology, in particular to a ground verification system and method for a micro-satellite navigation system based on the approach of a non-cooperative small-size target. Background technique [0002] In the field of aerospace, there are usually two methods of semi-physical simulation and air-floor table for ground verification of satellite navigation systems based on target approach. The semi-physical simulation method means that the satellite navigation system uses real products and algorithms, uses computers to simulate the state characteristics and motion characteristics of the approached target, and inputs the above information into the measurement components of the satellite navigation system through the ground test interface. The air-floor platform method is to install special air feet on the satellite and the approached target, and make the satellite and the approached target suspended on the air-fl...
