Embodiment Construction

[0026] like figure 1 As shown, the device of the present invention is composed of a time-frequency signal generator 1 , uplink injection signal testing equipment 2 , downlink navigation signal receiving testing equipment 3 , time interval counter 4 and testing and evaluation software 5 .

[0027] Example by figure 1 connection shown. The time-frequency signal generator 1 provides time-frequency reference signals and unified time standards for all equipment of the RNSS payload test device; the uplink injection signal test device 2 is driven by the time-frequency signal provided by the time-frequency signal generator 1 to receive the test evaluation software 5. The time signal, control command, parameter setting and message information sent out will generate an uplink injection signal containing message information and adjust it to an appropriate level, and then send it to the satellite RNSS payload (device under test) for the uplink payload test; the downlink navigation signal...

Abstract

The invention discloses a universal apparatus which can be applied to navigation satellite RNSS payload tests. The apparatus integrates a time frequency signal generator, an uplink injection signal testing device, a downlink navigation signal receiving testing device, a time slot counter and a test evaluation software. The apparatus can generator an uplink injection signal which is intended for testing the performances of a RNSS payload uplink injection receiver. The apparatus can also receive a RNSS payload downlink navigation signal which is intended for testing the performances of a RNSS downlink straight launching payload. The apparatus has the characteristics of high device integration, comprehensive testing coverage, and excellent flexibility. The apparatus also supports batch testsof satellites, and fills the blank in the field of RNSS payload testing. The apparatus also ensures test effectiveness by adopting a special-purpose test evaluation software.

Description

technical field [0001] The invention relates to the integration and versatility of payload testing equipment in the satellite navigation field, and is especially suitable for RNSS load batch testing and index evaluation in the satellite navigation field, with comprehensive test coverage, greatly saving satellite RNSS payload testing time, and improving testing efficiency . Background technique [0002] The RNSS payload test device in the navigation system is a high-precision and high-reliability satellite payload test device, which can generate uplink injection signals for RNSS payload uplink receiver performance testing; can receive RNSS payload downlink navigation signals, and use It is used to test the performance test of RNSS downlink direct load. Due to the complex system of uplink and downlink signals, different bandwidths and frequencies, and various types of messages, the RNSS payload test device must have sufficient versatility, flexibility and integration. At pre...
