GPS performs positioning or navigation by receiving satellite signals.To receive signals, an antenna must be used. 

Most GPS antennas are right-hand polarized ceramic media, and their components are: ceramic antennas, low-noise signal modules, cables, and connectors.

Antennas are generally placed outdoors and exposed to exposure to the sun, wind and rain.Therefore, its waterproof performance must be good, otherwise it will easily destroy the collected information and affect the accuracy of positioning or navigation.

What I want to share this time is aboutGPS antenna air tightness detection case。

Testing method: Use direct testing method to design the mold and tooling according to the shape of the GPS antenna.

Testing equipment: Hairis HC classic seriesAir tightness detector

After the mold and tooling are in place, place the antenna on the mold, select the set program, and press the start button. The mold will block the GPS antenna, and the instrument will enter the test program, and the instrument will pump air, stabilize voltage, and test.The system automatically determines the test results as OK or NG based on the set parameters.

Program parameters: air intake pressure 12.5Kpa, air intake time 10s, pressure stabilization 10s, test time 5s, deflation time 2s.If the leakage value does not exceed 30pa, it means that the air tightness test of the controller has passed, and the test result will also show OK.
