GNSS Corrections

Seamless and accurate navigation solutions

We offer a variety of GNSS (Global Navigation Satellite System) correction options for our high performance receivers to deliver highly accurate, reliable DGPS positioning using WAAS, EGNOS, GLONASS and Satellite GS-based DGPS corrections.

You’ll find a range of options to match your system needs, from sub-meter accuracy at one end of the spectrum to sub-inch accuracy at the other. Ideal for precision farming, GIS and other applications where a rugged, simple-to-operate receiver is required.

Please note: Achievable accuracy and convergence time may vary based on capability of receiver, antenna, ionospheric activity, and multipath environment.
