GPS L1+L5 antenna

　　GPS L1+L5 antenna is GPS L1 and L5 dual-frequency antenna. The following is a related introduction:

　　GPS L1+L5 antenna Working principle

　　L1 band working principle: The frequency of L1 band is about 1575.42MHz, which is mainly used to transmit civil navigation signals. GPS satellites send navigation messages containing satellite position, time and other information to the receiver through the L1 band. After receiving the L1 signal, the receiver measures the time delay of signal propagation by comparing it with its own clock, and then calculates the distance between the satellite and the receiver. Combining the distance information of multiple satellites, the three-dimensional position of the receiver is determined using the triangulation positioning principle.

　　L5 band working principle: The frequency of L5 band is 1176.45MHz, which is mainly used to improve positioning accuracy and reliability. L5 signals use more advanced coding and modulation methods, and have better anti-interference and penetration capabilities. In complex environments, such as urban canyons and dense forests, L5 signals can more effectively penetrate obstacles and be received by the receiver. At the same time, the L5 signal cooperates with the L1 signal to eliminate errors such as ionospheric delay, thereby improving positioning accuracy.

　　GPS L1+L5 antenna Features

　　High-precision positioning: The L1+L5 dual-frequency antenna can simultaneously receive signals from the L1 and L5 frequency bands. The dual-frequency signal can effectively eliminate the impact of ionospheric delay on positioning, thereby improving positioning accuracy. In urban environments, positioning accuracy within 2 meters can be achieved.

　　Strong anti-interference ability: The L5 frequency band signal has better anti-interference performance. Combined with the L1 frequency band, the antenna can still stably receive satellite signals in a complex electromagnetic environment, reduce signal interruptions and errors, and improve positioning reliability.

　　Good compatibility: It can not only receive L1 and L5 signals from GPS satellites, but also be compatible with the corresponding frequency band signals of other global navigation satellite systems such as Beidou, Galileo, GLONASS, QZSS, etc., support multi-system joint positioning, and further improve positioning accuracy and availability.
