Hemisphere A52 Geodetic Antenna

The A52 is ideal for many applications such as geodetic surveys, RTK navigation, and precise guidance. It has incredible mutipath mitigation as well as great SNR’s even in tough environments. The A52™ antenna adds more precision, reliability, and value to our leading Eclipse GPS technology. A52 is a multi-GNSS precision antenna and is ideal for various applications including geodetic surveys, RTK positioning and navigation, precise guidance, and machine control. Use the A52 antenna in challenging environments (such as near buildings and foliage) as it has superior multipath mitigation, stable phase center, and strong SNR’s even at low elevations.

Hemisphere’s A52 antenna is a multi-GNSS precision antenna and is ideal for various applications. With the A52 antenna, you have a solution that is capable of performing geodetic surveys, RTK positioning and navigation, precise guidance and machine control all within the same package. With a Multi-Constellation, Multi-Frequency design, the A52 is the antenna that can perform in challenging conditions. Hemisphere’s A52 has excellent performance in environments such as those near buildings and foliage where you would otherwise not be able to get correction data. The Hemisphere A52 allows you to get the corrections you need in the environments you never thought possible.
With access to triple frequency, the A52 has superior multi-path performance. The more powerful L5 signal has better multipath mitigation, allowing you to get corrections in environments you never thought possible. Hemisphere’s A52 is also a multi-constellation receiever. With access to GPS, GLONASS, Beidou, Galileo and SBAS, the A52 is the antenna with the technology to be used years into the future. This is the antenna to be used in challenging environments you would otherwise avoid.
The A52 geodetic antenna is also built to last. With an IP69K environmental rating and an EP455 vibration rating, Hemisphere’s A52 is built to be used in places traditional antennas would become damaged. This is the antenna that can remain in the elements for years to come and suffer no damage. Capable of working in temperatures of -40 °C to 70 °C, this is the antenna you can take anywhere. With the 5/8″ thread, the antenna is simple and easy to mount on your existing equipment. With the RF TNC connector, the A52 is the antenna with the solutions you need.
