High performance GNSS Antenna for UAV UGV RTK Aviation

GNSS Antenna

High performance GNSS Antenna for UAV UGV RTK Aviation

The external aviation antenna is a high-gain, low-wind resistance antenna. It has the characteristics of small size, exquisite appearance, high sensitivity and low power consumption, which greatly improves the accuracy and speed of positioning high-speed moving carriers. It can be used with a variety of receivers and is widely used in navigation and dispatching, tracking and monitoring, measurement and control and other fields. It is especially suitable for high-speed moving systems and fields, such as civilian drones, vehicle-mounted high-precision applications, etc. The antenna unit has high gain, a pattern beam width and more stable wide-angle circular polarization (WACP) performance. The antenna part adopts a multi-feed point design to achieve the coincidence of the phase center and the geometric center, reducing the impact of the antenna on measurement errors to minimum, thus ensuring more precise positioning accuracy..

Key Features

01

High Phase Center Stability

2018-07-16
The antenna part adopts a multi-feed point design and a completely symmetrical antenna structure, which has a relatively stable phase center and reduces the impact of the antenna on measurement errors.
01

Tracking in Challenging Environments

2018-07-16
The antenna has high gain, wide pattern beam, and good reception of signals at low elevation angles. It can receive stars normally in some situations with severe obstruction.
03

Strong anti-interference ability

2018-07-16
Adopting pre-filtering and multi-stage filtering scheme, it can effectively suppress out-of-band strong interference signals
04

Compact, lightweight, low wind resistance UV

2018-07-16
It ensures that the antenna can be used in harsh electromagnetic environments. It is compact, lightweight, and has low wind resistance. It also has an IP67 protection grade design and the outer casing effectively protects against ultraviolet radiation.
