Here’s how we deliver sub-metre or centimetre-level positioning accuracy:

  1. Superior, independently owned and operated GNSS reference network provides the raw data to generate corrections.
  2. Corrections processing generates highly precise GNSS satellite orbit, clock biases and other systems parameters that can be delivered globally to any NovAtel receiver.
  3. Satellite-delivery of corrections eliminates the need for base stations or cellular data plans.
  4. The high-rate, low-latency corrections provide NovAtel receivers with centimetre-level accuracy for any application.

TerraStar Correction Services offer a seamlessly integrated solution that delivers global coverage in any environment.
