High Gain Reception & Reliable Low-Noise Amplifier for Optimal Satellite Tracking
It is widely used in high-precision navigation and positioning applications in high dynamic environments such as aerospace, UAV, precision agriculture, ADAS, Autonomous Driving where aerodynamics play an crucial role while accuracy and reliability are not sacrificed.
Enhanced Performance and Precision
Double layer multi-feed point technology ensures high performance on right-hand circular polarization and phase center stability. It further lowers the measurement errors.
Optimized Reception
The overall design provides a high gain on low-elevation satellite signal reception so that a higher number of satellites are available for position calculation.
Improved Signal Quality
Pre-filtering on the low noise amplifier effectively suppresses out-of-band interference signals and improves the reliability of the system.
Versatile and Durable
The enclosure is rated IP67 which ensures a reliable performance in any harsh environmental conditions
