Satellite navigation signal simulated source magnitude calibration method

Abstract

The invention discloses a satellite navigation signal simulated source magnitude calibration method, which comprises the following steps: (1) setting and performing a transmission standard, checking whether the transmission standard is stable, and if so, transmitting, otherwise, continuing checking; (2) examining a simulated source to be calibrated, judging whether the simulated source is in a controlled state, and if so, performing a step (3), otherwise, interrupting; (3) measuring the navigation signal simulated source to be calibrated by using a client end through the transmission standard, and after the measurement, returning measured data and the transmission standard; (4) rechecking the returned transmission standard, judging whether the returned transmission standard is stable, and if so, performing a step (5), otherwise, interrupting; (5) judging whether the measuring process is in a controlled state according to an examination standard, and if so, performing a step (6), otherwise, interrupting; and (6) generating a calibration report, and returning the calibration report to the client end to form a closed loop. The invention has the advantages that the satellite navigation signal simulated source magnitude calibration method has a simple principle, is easy and convenient to operate and easy to implement, ensures accurate and reliable measurement and the like.

Description

technical field [0001] The invention mainly relates to the field of satellite navigation, in particular to a method for verifying the magnitude value of an analog source of a satellite navigation signal. Background technique [0002] The Global Navigation Satellite System (GNSS) can provide all-weather precise position and time information for any place in the earth and near-Earth space. Satellite navigation signal simulation technology and its equipment are high-precision simulations of real satellite navigation systems, which can provide critical information for the development, production, application, testing, and simulation training of GNSS receivers and their systems in a controlled laboratory environment. testing and validation support. The satellite navigation signal simulation source can provide a reliable and efficient testing method for GNSS receivers and various systems that rely on GNSS receivers. [0003] According to the provisions of the metrology law, the ...
