Gps Antenna requirements
With the wide application of Global Positioning system (GPS) technology, the performance requirements of GPS antenna, as the key equipment to receive GPS signals, are becoming more and more stringent. The purpose of this paper is to discuss the requirements of GPS antenna and analyze its application in different fields.
Basic requirements of GPS antennas
1. Reception sensitivity: the GPS antenna should have good reception sensitivity to ensure that it can work stably in the weak GPS signal environment.
2. Anti-jamming ability: GPS antenna should have strong anti-jamming ability to deal with electromagnetic interference in the environment and ensure the stable reception of the signal.
3. Polarization mode: the polarization mode of GPS antenna should match the polarization mode of satellite signal transmission, which is commonly used in circular polarization and linear polarization.
4. Frequency range: GPS antennas should cover the frequency range of GPS signals to ensure full reception of satellite signals.
5. Stability: the GPS antenna should have excellent stability, including temperature stability, aging stability, etc., in order to ensure long-term and stable performance.
6. Anti-jamming performance: for complex environment interference such as multipath effect, GPS antenna should have excellent anti-jamming performance.
