Airborne GNSS

Overview
  • · High-gain, wide-beam characteristics deliver excellent reception performance even at low elevation angles, enabling reliable satellite signal reception in heavily shielded environments
  • · Front-end and multi-stage filtering architecture effectively suppresses out-of-band jamming and interference
  • · An integrated voltage stabilisation circuit ensures stable operation across a wide input voltage range
  • · Features an integrated waterproof design with a protection rating of IP65
Description

Aviation GNSS antennas are designed to provide stable and reliable satellite navigation signal reception for aircraft, unmanned aerial vehicles (UAVs), and high-speed mobile platforms. Taking into account the demanding conditions of aviation environments—such as high-speed movement, vibration, and variations in air pressure and temperature—these antennas are engineered with a strong focus on lightweight construction, environmental robustness, and signal stability.

Aviation GNSS antennas are typically configured in a mini airborne antenna form factor, featuring a compact and low-weight design optimised for integration into airborne platforms and other applications where size, weight, and performance are critical.
