Embodiment Construction

[0034] Such as figure 1 As shown, the present invention seamlessly integrates the BD2 navigation simulator and the Sporun GPS / GLONASS navigation simulator. The high-precision 10MHz signal and 1PPS signal are output by the clock synchronization unit to realize the clock synchronization of each simulator and the integrated control unit. The integrated control unit receives the dual-user trajectory information sent by the external equipment through the Ethernet, and sends control instructions and user trajectory information to each simulator to realize data synchronization of the system. The radio frequency combining unit combines the radio frequency signals output by the simulator, and finally outputs the navigation signals of the dual users.

[0035] Such as figure 2 As shown, the integrated control unit is connected to the external trajectory generator, GSS800 simulator, and CSG6000 simulator through Ethernet; the external clock signal interfaces of the GSS800 simulator and...

Abstract

The invention discloses a combined testing system integrating a BD2 navigation simulator with a GPS (global position system) / GLONASS navigation simulator. The combined testing system comprises two simulators CSG6000BD2, two Spirent simulators GSS8000, a comprehensive control unit, a clock synchronization unit and a radio-frequency combining unit. By the combined testing system, the BD2 navigation simulator and the GPS / GLONASS navigation simulator can be controlled simultaneously to be integrated seamlessly to build a GNSS (global navigation satellite system) combined testing system which can receive double user trajectories generated by an external trajectory generator simultaneously, generate GNSS navigation signals of a GPS, a GLONASS and a BD2 system simultaneously and support closed-loop testing of a flight control system and index testing of a GNSS compatible receiver.

Description

technical field [0001] The invention relates to a combined test system integrated with a BD2 navigation simulator and a GPS / GLONASS navigation simulator, belonging to the technical field of satellite navigation. Background technique [0002] With the development and construction of the global satellite navigation system, GNSS receivers have been applied in various fields and industries. The development and testing of GNSS receivers are inseparable from navigation signal simulators. [0003] At present, the multi-system GNSS test system of related foreign companies has been listed, and can provide test support for GPS / SBAS, GLONASS, Galileo and QZSS. But currently there is no simulator or simulation platform that can simultaneously generate or choose to simulate multi-system satellite navigation signals including the BD2 system. [0004] The integrated technology of BD2 navigation simulator and GPS navigation simulator can integrate the domestic BD2 navigation simulator wit...
