Launched in June 2015, Atlas™ is Hemisphere GNSS’ new GNSS correction service, offering the most innovative correction service available in the industry, providing performance that meets or exceeds that delivered by other industry leaders, at market-leading prices.

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

Atlas support is being introduced across a wide range of multi-frequency, RTK-capable hardware, including Hemisphere’s all-new AtlasLink™ GNSS smart antenna, R330u, V320, VS330u, P306 (when paired with LX-3), and H321. Atlas also supports third-party GNSS receivers via Hemisphere’s innovative SmartLink™ and BaseLink™ capabilities.
