Overview of GPS Antenna performance
The performance of GPS antenna mainly includes sensitivity, gain, beamwidth, polarization mode, anti-jamming ability and so on. Sensitivity is the ability of GPS antenna to receive weak signal, which directly affects the positioning speed and accuracy. Gain represents the ability of antenna to amplify the signal, which plays an important role in improving positioning accuracy and reducing error. Beamwidth reflects the orientation of the antenna and is very important to improve the quality of signal reception. The polarization mode determines the way the antenna receives the signal, which affects the stability and anti-jamming ability of the signal.
