Embodiment Construction

[0076] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0077] Such as figure 1 As shown, it is a schematic flowchart of the verification method of the satellite navigation signal analog source value of the present invention, which mainly includes a transmission process, a verification process and a data processing process. The value verification of all satellite navigation signal analog source key technical indicators is all completed on the basis of the flow process of the present invention, and its specific flow process is:

[0078] Step 1: Start testing. For example, the user laboratory applies to the metrology institution to start the quantitative verification of the key technical indicators of the satellite navigation signal simulation source.

[0079] Step 2: Set and communicate delivery criteria, then check. The metrology institution selects a general-purpose instrument as the t...

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 ...
