Antenna receiving gps (Antenna receiving GPS, exploring the core components of modern positioning technology)
With the wide application of Global Positioning system (GPS) technology, antenna receiving GPS signal plays an important role in various fields. From automobile navigation, smart phone positioning to aerospace field, GPS technology can not be separated from antenna receiving GPS signal. This paper will introduce the basic principle, type, application and future development trend of antenna receiving GPS in detail.
The basic principle of Antenna receiving GPS
GPS system is based on satellite signals for positioning, and the antenna is the key equipment to receive these signals. The basic principle of antenna receiving GPS signals is as follows:
1. Transmitting and receiving: GPS satellites continuously transmit radio frequency signals, and ground equipment receives these signals through antennas.
2. Signal processing: the received GPS signal is amplified, filtered and converted to extract the pseudorandom noise code (PRN code) and carrier frequency information of the satellite.
3. Positioning calculation: by measuring the signal propagation time of multiple satellites received, combined with the satellite position information, the geographical position of the receiver is calculated.
Type of GPS received by the antenna
According to the use and performance requirements, the antenna receiving GPS can be divided into many types, including:
1. Vehicle GPS antenna: mainly used in automobile navigation system, which has the characteristics of small size, light weight, strong anti-interference ability and so on.
2. Handheld GPS antenna: suitable for hiking, outdoor sports and other scenes, with portable, easy to operate and other advantages.
3. Aerospace GPS antenna: used in aircraft, UAV, spacecraft and other high-end fields, with high precision, high stability and other requirements.
4. Base station GPS antenna: used in network positioning, time synchronization and other fields, it is required to receive multiple satellite signals with high performance.
Application of Antenna receiving GPS
