We are pioneers and global leaders in satellite-based correction services with our highly reliable and available TerraStar services. Superior GNSS reference stations, redundant system architecture and continuous quality monitoring contribute to an exceptional service that is available anytime, anywhere. TerraStar Correction Services transmit correction data in real-time, with minimal latency, directly to NovAtel receivers via satellite link or Internet connection to provide a robust solution, no matter where you are in the world.

TerraStar is available for use in a variety of applications including precision agriculture, construction, survey, UAV and ground truth systems. With a range of options to fit your needs, TerraStar is as precise as you need to be. With the highest reliability clock and orbit data from our world-wide reference network means you have assured, reliable positioning anywhere, anytime.

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.
