Product introduction
The antenna adopts a four-arm spiral structure with a relatively stable phase center, which reduces the influence of the antenna on the measurement error; The antenna gain is high, the beam pattern is wide, and the effect of receiving low elevation signals is good, ensuring that the antenna can receive the satellite in different attitudes; The antenna is equipped with a high-band out-of-band suppression low-noise amplifier circuit, which can effectively resist external electromagnetic interference, and has low power consumption to ensure the endurance of the device; The antenna is small in size and light in weight, and is suitable foruse on various devices that require antenna weight, such as drones and various handheld terminals.
Application
This antenna is a full-band measurement choke antenna covering GPS L1 / L2, GLONASS L1 / L2, BDS B1 / B2 / B3, Galileo E5a / E5b / E2-L1-E1, which meets the requirements of multi-system compatibility of current measurement equipment And extremely high-precision micro-deformation measurement; it is mainly used in some places that have extremely high measurement accuracy requirements, such as earthquake prediction, high-precision differential reference stations, and other demanding applications.
