Technical principle of GPS measuring Antenna
GPS measurement antenna is the key equipment to receive GPS satellite signal. Its main function is to convert the received GPS satellite signal into disposable electrical signal. Its technical principle mainly includes the following aspects:
1. Satellite signal reception: the GPS measuring antenna obtains the position information of the satellite by receiving the radio frequency signal transmitted by the GPS satellite.
2. Signal conversion: the antenna converts the received RF signal into electrical signal for analysis by the subsequent signal processing circuit.
3. Data processing: after the signal received by the antenna is processed, the position and time of the satellite are extracted, and the distance between the receiver and the satellite is calculated.
4. Positioning and navigation: through the distance information of multiple satellites, the GPS measuring antenna can calculate the position of the receiver (longitude, latitude and altitude), thus realizing the function of positioning and navigation.
Types and characteristics of GPS measuring Antenna
According to the usage scenarios and performance requirements, GPS measurement antennas can be divided into many types, including:
1. Portable GPS measurement antenna: small in size and light in weight, suitable for field survey, geological exploration and other fields.
