Overview
The Harxon HX-GS288A mini GNSS survey antenna receives GPS L1 and GLONASS L1 frequencies, which can be used in land survey, marine survey and agriculture applications. Customers can use the same antenna for GPS only or dual constellation applications.
It has high gain ensure the signal receiving performance of satellites at low elevation angles. The phase center of this antenna remains constant as the azimuth and elevation angle of the satellites change. Signal reception is unaffected by the rotation of the antenna or satellite elevation, so placement and installation of the antenna can be completed with ease.
All of Harxon’s antennas provide invariant response over the full range of operating voltages and operating temperatures.
Features
