Atlas GNSS Global Correction Service

Atlas is an innovative, industry-leading GNSS-based global L-band correction service, providing robust performance at competitive market prices. Atlas is a flexible and scalable service, delivering its correction signals via L-band satellites at accuracies ranging from meter to sub-decimeter levels. Leveraging more than 200 reference stations worldwide and with L-band satellites distributing Atlas corrections, the entire globe is virtually covered. The Atlas GNSS global correction service provides correction data for GPS, GLONASS, BeiDou, and Galileo constellations.

Atlas correction service is available on all Hemisphere Atlas-capable single- and multi-frequency, multiGNSS hardware. Atlas complements third-party GNSS receivers by allowing them to use Atlas corrections with Hemisphere’s innovative BaseLink® and SmartLink™ capabilities.

When using multi-frequency hardware, Atlas corrects more satellites than ever before, which creates faster convergence times and is robust and reliable in canopy or foliage covered areas. With both single- and multi-frequency hardware, Atlas achieves instant global sub-meter positioning accuracy, comparable to, and typically more robust than SBAS, since Atlas corrections contain data from multiple available constellations.
