Hemisphere GNSS is offering a series of enhancements to its Atlas GNSS global correction service, including Atlas Basic, Atlas AutoSeed and the addition of global ionospheric modeling to the system. Atlas is a flexible, scalable GNSS-based global L-band correction service, providing robust performance and correction data for GPS, GLONASS and BeiDou.
“Having the ability to easily scale your correction service levels based on specific use cases is essential to our customers and OEM partners,” says Miles Ware, director of marketing for Hemisphere GNSS. “With the addition of Atlas Basic, we are making it easier for anyone with an Atlas-capable single- or multi-frequency, multi-GNSS receiver to achieve sub-meter, SBAS-equivalent positioning accuracy virtually anywhere on earth.”
Delivering its correction signals via L-band satellites at accuracies ranging from meter to sub-decimeter levels, Atlas also leverages approximately 200 reference stations worldwide, providing coverage to virtually the entire globe. Hemisphere is now offering Atlas Basic. Atlas Basic provides users of both single- and multi-frequency Atlas-capable hardware the ability to achieve SBAS-equivalent performance anywhere in the world where the Atlas correction service is available. Atlas Basic is a new feature that offers a proven accuracy of 30 centimeters to 50 centimeters, and offers instantaneous sub-meter accuracy allowing for DGPS-level accuracy.
Also included in the enhanced Atlas system is the addition of global ionospheric modeling. Using real-time ionospheric data, Atlas adjusts its corrections accordingly, providing instantaneous convergence for sub-meter accuracy. Atlas’ new AutoSeed technology allows users to suspend Atlas use for any period, and upon returning to their last location, AutoSeed rapidly re-converges to a high-accuracy converged position.
Atlas is available on all Hemisphere Atlas-capable single- and multi-frequency, multi-GNSS hardware and complements third-party GNSS receivers by allowing them to use Atlas corrections with Hemisphere’s innovative SmartLink and BaseLink capabilities. When using multi-frequency hardware, Atlas corrects more satellites than ever before, to create 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.
Hemisphere is currently offering Atlas Basic as activation on all Atlas-capable single- and multi- frequency Hemisphere products purchased before Feb. 1, 2018. Correction service users will no longer need subscriptions for Atlas Basic service levels at 50-centimeter (95%) accuracies.
