Swegeo SA20
High Gain Reception & Reliable Low-Noise Amplifier for Optimal Satellite Tracking
It is widely used in high-precision navigation and positioning applications such as geodetic surveying/mapping, hydrographic mapping, precision agriculture, ADAS, Autonomous Driving, and Deformation monitoring where an accurate and reliable system is crucial.
Enhanced Performance and Precision
Multi-feed point 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.
