RTK Corrections

Polaris provides RTK corrections anywhere in the world — no base station required

Point One built the Polaris network from the ground up — it manages over 1440+ base stations across the U.S., Canada, Europe, Australia and more. It’s deploying additional base stations each month to meet customer demand. Works with any RTK compatible receiver (RTCM v3).

RTK corrections subscription service

The Polaris network observes the components of error present in existing satellite signals (atmospheric delay due to ionospheric and tropospheric disturbances, satellite clock errors, and satellite orbit errors) and precisely calculates a corrections data for your application.

Point One owns and manages 1400+ base stations around the world

  • Highest overall density of U.S. corrections networks
  • Extra redundancy in urban centers (top 50 cities in the US all have over 4 stations)
  • Tracks four major constellations: GPS, GLONASS, Galileo, BeiDou
  • Uses the WGS84 (G1150 Initial Epoch) coordinate reference system
  • Easy-to-expand network, driven by customer demand
  • Even in areas without cellular coverage, Polaris provides high accuracy GNSS corrections with delivery over satellite
  • 99.99% uptime

How is Point One different from standard GNSS?

Point One builds high precision GNSS solutions. Standard GNSS accuracy ranges from 1m to 10m and can be worse based on the operating environment. Point One’s high precision GNSS delivers accuracy from 10cm to 1cm, and does so even in challenging environments such as urban canyons and occluded sky-views

What is Precision GNSS?
Standard GNSS systems observe position uncertainty from sources such as atmospheric signal delay, satellite orbit variation, clock drift, and signal multi-path. Precision GNSS systems use additional sources of information, in our case from our Polaris corrections network, reducing uncertainty down to just a few centimeters.
How do I get started using Point One as a developer?
Purchase a Standard Dev Kit, purchase an Advanced Development Kit, or create a Point One account to access Polaris corrections and services.
What products already integrate Point One?
Many, including series production automobiles, consumer electronics products, and autonomous vehicle prototypes.
What is RTK?
Real Time Kinematics; a fixed base station communicates with a roving GNSS system to remove sources of error common to the base and rover (satellite clock, satellite orbit, ionosphere delay, troposphere delay). Rover performance depends on survey accuracy of base location, quality of sky view at base location, and distance between base and rover.
Can I use Polaris corrections with a non-Point One system?

Yes. The Polaris network performs as an  RTK network. Non-Point One systems can access the Polaris network using standard NTRIP protocol. Access credentials and documentation are available at app.pointonenav.com.

What is the difference between Polaris and NTRIP corrections?
Both Polaris and NTRIP are methods for delivering network RTK corrections, and both are available through the Point One Polaris service. The NTRIP standard is a legacy delivery method, used by a wide range of GNSS devices. The Polaris protocol uses secure connection methods for both authentication and transport to add layers of reliability and security to RTK corrections data.
