RTK From the Sky tech transforms TerraStar-C PRO service with 3-minute global convergence

January 25, 2022  - By

TerraStar-C PRO is the first global correction service from Hexagon to incorporate RTK From the Sky technology to achieve RTK-level accuracy in three minutes with 99.999% availability

In late 2020, Hexagon’s Autonomy & Positioning division announced its technological breakthrough of global RTK From the Sky, demonstrating a future where instantaneous PPP and global RTK-level accuracy is possible.

Integrating this innovation into the core of TerraStar-C PRO, NovAtel’s corrections service, is the first phase in implementing RTK From the Sky technology into the company’s diverse portfolio of correction services for users worldwide.

As a result, TerraStar-C PRO has become the fastest global correction service to provide centimeter-level accuracy, not just in open-sky environments but also across challenging conditions created by buildings and foliage, according to Hexagon | NovAtel.

“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,” said Michael Ritter, Autonomy & Positioning division president and CEO. “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.”

TerraStar-C PRO now converges in less than three 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.

Hexagon is a consistent innovator in GNSS, as seen in its role in developing RTK and PPP solutions. With this next-generation modernization of PPP correction generation and algorithm development, the company continues this tradition in providing the highest quality and best performing global positioning experience to users with land- and air-based applications.

“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,” said Leos Mervart, head of PPP algorithm development at Hexagon’s Autonomy & Positioning division. “I’ve worked with PPP technologies since the beginning of my career and am proud to say that this is a new era of what global positioning can look like.”

The 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.

Future firmware releases will include global RTK From the Sky technology throughout Hexagon’s correction service portfolios for its global client base, including precision agriculture and marine applications.
