How to test the high precision positioning module?

       As a company specializing in GNSS modules and wireless communication products, technology development and application promotion, each GPS module from production to shipment are subject to a strict quality inspection process.

       Ensure that each piece of GPS module to the hands of customers are quality assured, in addition will provide a complete GPS module specifications, test reports, use of documents and other related information, for customers with GPS module testing needs, will also provide supporting detailed manual. This experience sharing, a brief introduction to the test method of high-precision positioning module.

Prepare the computer, high-precision positioning module (SKG12UR), EVB board, high-precision positioning antenna, Micro USB power cable, as shown in the figure:

High-precision positioning module test

1、According to the instruction manual, supply power correctly to the high-precision positioning module soldered on the EVB board; and according to the example diagram, connect the high-precision positioning antenna, and the active antenna needs to be powered correctly;

3. The module outputs NMEA statement from the serial port, connects to the Internet, uses the SKG account to get the differential data, and runs the SKG SDK to solve the position.

    The above is the test method of high-precision positioning module. There are various methods, this article is only experience sharing for reference.
