Hemisphere - Model S321 -GNSS Survey System

The newest GNSS antenna from Hemisphere, the S321 is one of the best units available today. Feature-packed, it takes survey grade accuracy and functionality to a new level, and it’s intuitive user interface makes it much simpler to setup and operate than any other survey receiver we’ve ever used. Utilizing the latest Athena GNSS engine, the S321 converges to RTK fix in a matter of seconds, works extremely well in tough conditions such as near trees and buildings, and offers class-leading performance over long baselines – even up to 50km on our CORS network we’ve experienced 2″ or better repeatable accuracy and very fast convergence times.
