Hemisphere GNSS

Atlas™ is Hemisphere GNSS’s new L-Band GNSS correction service, offering an innovative service that provides performance that meets or exceeds that delivered by other industry leaders, at market-leading prices.

Atlas L-Band service is the most flexible service on the market, delivering its correction signals via L-Band satellites or over the Internet at accuracy ranging from sub metre to sub-decimeter levels. With approximately 200 reference stations worldwide and L-Band satellites distributing coverage from 75°N to 75°S to ensure all of the earth’s landmass is covered.

There are 3 subscription levels - H10 gives approx. 10 cm accuracy. H30 gives 30cm accuracy and the Atlas basic gives 0.5m accuracy which is much the same accuracy when using the AMSA marine beacon. Please ring for a cost on the Atlas service.

The Atlas subscription supports the below Hemisphere GNSS receivers. The Atlas Link, the R330 and the S321.


The Atlas Link is Hemisphere's GNSS Smart Antenna which uses the 3 main satellite constellations USA's GPS, Russia's 'GLONASS' and China's 'BeiDou'.  An approximate cost for this receiver is $3,750 exGST.
