Introduction
A whole set of COMPASS antenna consists of a ceramic patch antenna, LNA, cable, connector and housing. This antenna is mainly used to receive and transmit GPS and COMPASS signals. They are widely used in devices with navigation and positioning functions, like vehicles and handsets.
Advantages
1. All our COMPASS antennas have been strictly tested on production line and the first pass yield is 99%.
2. High gain, low loss and strong ability to receive signals are our antennas’ features.
3. 28 years’ manufacturing experience in HF antennas assures our leading position in antennas industry.
4. Our products are resistant to corrosion. They all have passed 48-hour salt fog test.
5. COMPASS antennas are water proof. The water-proof degree is IP67.

Description of COMPASS
Our COMPASS antennas are developed specially for Chinese COMPASS system. BeiDou (COMPASS) navigation satellite system is a global satellite positioning and communication system developed by China. It is the third mature satellite navigation system besides American GPS and Russian GLONASS. COMPASS system can provide positioning, navigation and timing service of high precision and reliability. In addition, it has short message communication ability. COMPASS navigation system is approved as supplier of satellite navigation system by UN satellite navigation committee.
