The rigid standards that a qualified product should have

First, the project design
Navigation scheme is the core of the whole hardware, and its quality decides the performance of the product. At present, the world's largest provider of navigation solutions is far from the peak program.
Two 、 performance test
Including analog star test, outdoor multi direction star search test, EMI (anti-jamming) test, WIFI test, compatibility test, flash test, etc..
Three 、 practical application test
Road test. Testing the accuracy and tracking ability of navigation products in dynamic situations, usually using Google Earth to display test product trajectories.
Four 、 reliability test
That is, physical testing, including high and low temperature work, high and low temperature storage, high temperature and humidity work, vibration testing, drop test, alcohol resistance test, etc..
