APPLICATION
-
The antenna adopts a four-arm spiral structure, ensuring a small error between the antenna’s phase center and geometric center. This effectively reduces measurement errors caused by the antenna.
-
The antenna has high gain, a broad directional beam, and performs well in receiving low-elevation angle signals.
-
The antenna is compact, lightweight, and suitable for devices with weight requirements, such as in the field of unmanned aerial vehicles (UAVs). The antenna has low power consumption, effectively ensuring the device’s battery life.
SPECIFICATION
This antenna is a seven-frequency four-arm active spiral antenna that covers GPS L1/L2, BDS B1/B2/B3, GLONASS L1/L2. It is widely used in navigation dispatch, tracking monitoring, measurement and control, and other fields. It is particularly suitable for various applications such as drones, including aerial photography, traffic monitoring, remote telemetry, etc. Additionally, it can be applied to various handheld terminals and high-precision positioning modules.
