Problems solved by technology
The traditional satellite navigation terminal test is generally performed in a dark room, and the closed-loop test is mainly performed by simulating and broadcasting different scenarios through a simulator. The tested equipment is also mainly an ordinary user terminal, and it is impossible to carry out tests on directional user terminals and high-dynamic user terminals.
However, testing outdoors against the sky has the limitations of the test equipment, and it is impossible to carry out tests in high-dynamic scenarios, and can only achieve tests in static or low-dynamic scenarios.

The invention discloses a method for dynamically testing the height of a navigation terminal to the sky, and belongs to the technical field of satellite terminal testing. The method comprises the following steps that 1, a high-dynamic scene initial state and a working mode for are set for a high-precision rotating platform through an upper computer; 2, a Beidou time service receiver sends time service information and a 1PPS synchronizing signal to a control circuit module of the high-precision rotating platform; 3, the upper computer sends motion information to a control circuit module of the high-precision rotating platform, so that the high-precision rotating platform performs high-dynamic scene rotation; 4, after the upper computer resets the tested equipment, setting a working mode of the tested equipment; 5, the upper computer receives and stores the position information reported by the high-precision turntable and the tested equipment at each moment; and 6, the upper computer compares the reported position information of the high-precision turntable with the position information reported by the tested equipment to obtain a test result. According to the invention, the application field of high-dynamic navigation terminal testing is expanded.
Description
technical field [0001] The invention relates to the technical field of satellite terminal testing, in particular to a method for dynamically testing the height of a navigation terminal against the sky. Background technique [0002] At present, with the rapid development of satellite navigation technology, the test requirements of satellite navigation terminals are becoming more and more diverse. Traditional satellite navigation terminal tests are generally performed in a darkroom, and the closed-loop test is mainly performed by simulating and broadcasting different scenarios through a simulator. The devices under test are also mainly ordinary user terminals, and it is impossible to carry out tests on directional user terminals and high-dynamic user terminals. However, testing outdoors against the sky is limited by the test equipment, and it is impossible to carry out tests in high-dynamic scenarios, and can only achieve tests in static or low-dynamic scenarios.
