NovAtel GNSS Corrections Service Upgraded with RTK-Level Accuracy

By Mike Ball / 27 Jan 2022

OEM7700 Multi-Frequency GNSS ReceiverHexagon | NovAtel has confirmed that its TerraStar-C PRO GNSS corrections service can now achieve RTK-level accuracy in three minutes with 99.999% availability, thanks to innovative RTK From the Sky technology.

Integrating this technology into the core of TerraStar-C PRO is the first phase of implementing RTK From the Sky technology into Hexagon | NovAtel’s diverse portfolio of correction services for users worldwide. TerraStar-C PRO is now the fastest global correction service to provide centimetre-level accuracy not just in open-sky environments but also across challenging conditions created by buildings and foliage.

TerraStar-C PRO now converges in less than a few minutes by utilizing quad-band receiver and antenna technology to leverage modernized BeiDou III, GPS III and Galileo E6 signals. The resulting process generates state-of-the-art corrections for all GNSS frequencies.

These TerraStar-C PRO improvements are accessible now through the 7.08.10 firmware release for users on OEM7700, OEM719 and OEM729 cards and their associated enclosures for land and air applications such as UAVs (unmanned aerial vehicles) and UGVs (unmanned ground vehicles). Future firmware releases will bring global RTK From the Sky technology across Hexagon’s correction service portfolios to the rest of the diverse global client base, including precision agriculture and marine applications.

Michael Ritter, Hexagon’s Autonomy & Positioning division president and CEO, commented: “RTK From the Sky technology is the foundation that enables our global correction services to be world-leading across agriculture, automotive, defense, survey, marine and autonomous applications. Our dedication to research culminated in an industry-changing technology; we’ll continue that commitment by providing the best positioning experience in speed, accuracy, availability and reliability anywhere in the world.”

Dr. Leos Mervart, head of PPP algorithm development at Hexagon’s Autonomy & Positioning division, stated: “It’s been a privilege to collaborate across the division to develop RTK From the Sky technology and leverage our collective expertise in correction generation, PPP algorithms and the entire positioning ecosystem. I’ve worked with PPP technologies since the beginning of my career and am proud to say this is a new era of what global positioning can look like.”
