Autonomous Robotics | TerraStar

Autonomous Robotics

Robotic and autonomous vehicles require an accurate absolute position and relative position to other vehicles for safe operation and navigation. Centimetre-level accuracy without being tied to base stations is key for mobile operations and maneuvering through sub-optimal conditions. Precise point positioning (PPP) correction services through TerraStar ensure your solution consistently knows its location relative to other vehicles or obstacles as it navigates through the world.




Reliable GNSS corrections with built-in redundancy

TerraStar Corrections are delivered through Terrastar Demoredundant IP and L-Band channels, ensuring your solution maintains its precise position even through challenging conditions like a reduced view of the sky. With an availability of 99.999%, users can trust they’ll receive correction data when and where it's needed.


Why does consistent availability matter?

Positioning resiliency

Building a layer of protection against multipath and suboptimal operating conditions. Redundant and reliable delivery of corrections to the vehicle ensure quick response times to adapt to a changing environment for operational success.

Unlimited range

Maintain RTK-levels of accuracy without being tethered to a base station. Improve your overall position, navigation and timing through highly accurate and available corrections.

Simple integration and scalability

Consistent global performance makes TerraStar subscriptions simple and scalable across fleets of autonomous vehicles and robotic units. Our RTK ASSIST subscriptions improve the availability and range of existing RTK systems to improve your existing solution.


How can TerraStar improve your positioning solution? 

TerraStar corrections can provide the added availability, reliability and highly precise accuracy you require for autonomous applications. 

I need an easy-to-integrate solution

With TerraStar, all you need is a GNSS/GPS receiver and antenna from Hexagon | NovAtel with an active subscription. It’s a simple setup from a complex system providing 99.999% availability, full reliability and RTK-level accuracy worldwide.

I need bridging through RTK interruptions

Our RTK ASSIST and RTK ASSIST PRO services extend your RTK positioning through any outages. Leveraging PPP corrections to augment RTK allows TerraStar to extend your usable RTK operating conditions through any correction outages, enabling reconvergence in seconds. The satellite connection runs in the background, delivering corrections over L-Band frequencies to your L-Band enabled receiver, meaning that no additional devices, antennas, cables, or communications connectivity are required. 

I need corrections that are reliable and robust

TerraStar services like TerraStar-C PRO and RTK ASSIST PRO provide corrections for multiple constellations, including GPS, GLONASS, Galileo and BeiDou signals. This multi-constellation support empowers users to take advantage of more visible GNSS signals, helping build a positioning solution that is more reliable and robust enough to withstand GNSS interruptions or outages. 

I need a solution with rapid convergence

TerraStar-C PRO and TerraStar-X provide rapidly converging PPP solutions and reconverge in under one minute after GNSS signal interruptions. For established RTK users, RTK ASSIST and RTK ASSIST PRO reliably bridge your RTK position, converging at the same rate as your RTK solution while maintaining independent centimetre-level positioning.

I need a service with 99.9% availability or better

Availability describes the percentage of time that correction data is actively transmitting. 99.999% availability means data transmission is always on. If you do the math on 24/7/365 availability, 99.999% of reliability means a maximum outage of 5.3 minutes across the year.

This level of signal availability underlines the reliability users expect from TerraStar services. We’ve delivered services with 99.999% availability for several decades, ensuring our users have the corrections required for accurate positioning across environmental conditions. TerraStar is the trusted source for high-demanding users who can’t afford any interruptions or downtime. Visit our RTK From the Sky hub page to learn how we measure availability in our correction services.
