Beidou GPS antenna
With the continuous development of global positioning technology, Beidou GPS antenna, as the key equipment to receive Beidou satellite navigation system, is becoming more and more important. Beidou GPS antenna can not only achieve accurate positioning, but also widely used in intelligent transportation, UAV, Internet of things and other fields. This paper will deeply analyze the relevant knowledge of Beidou GPS antenna, including its working principle, type, performance index and application prospect.
Working principle of Beidou GPS Antenna
Beidou GPS antenna is a device for receiving Beidou satellite signals, which can accurately locate the target position by receiving radio signals transmitted by the satellite. Its working principle mainly includes the following steps:
1. Received signal: Beidou GPS antenna receives radio signals transmitted by Beidou satellite, which contain time and position information.
2. Signal processing: the antenna amplifies, filters and converts the received signal to facilitate the analysis of the follow-up circuit.
3. Analyze the signal: by analyzing the processed signal, the time information and navigation message of the satellite are extracted.
4. Location calculation: according to the extracted time information and navigation message, combined with the clock information of the receiver, the target position is calculated.
Types of Beidou GPS antennas
According to different application scenarios and requirements, Beidou GPS antennas can be divided into many types. Common types include:
