TOPGNSS Hand-held spiral GNSS antenna
TOPGNSS The antenna has a built-in GNSS L1+L5 helical antenna design, which has the characteristics of small size, high positioning accuracy, and light weight, which can meet the requirements of high-precision rtk positioning.
Feature 1: Lightweight. The total weight of the antenna is less than 16g, which is suitable for drones, high-precision handheld gnss equipment, small unmanned vehicles, unmanned ships and other high-precision navigation equipment. Can greatly reduce the load burden.
Feature 2: Easy to install, the antenna adopts standard SMA connector for feeding and transmission.
Feature 3: The antenna adopts a four-arm spiral structure, with excellent omnidirectional radiation characteristics, better low-elevation gain and wide-angle circular polarization characteristics, and can receive more low-elevation satellite signals.
