Positioning Services

NovAtel® focuses on delivering accurate positioning services that are scalable, versatile and customizable to meet the requirements of every autonomy level. Our portfolio of positioning services includes both correction services and GNSS positioning engines and is designed to meet the challenge of precise and functionally safe positioning while giving customers the ability to customize services for their exact needs. 

Positioning Engine

The software positioning engine accepts measurements from automotive-grade GNSS chipsets and Inertial Measurement Units (IMUs) to produce an accurate position, velocity and attitude solution for vehicle or feature control. The architecture of the software positioning engine is customizable and designed to be able to accept data from a variety of IMUs and other sensors such as cameras, LiDAR and wheel sensors.


  • Multi-constellation and single or multi-frequency GNSS positioning
  • Precise positioning algorithms: Precise Point Positioning (PPP) and Satellite-Based Augmentation System (SBAS)
  • GNSS integrity and authentication for automotive applications
  • GNSS+INS fusion with dead reckoning using the SPAN® Land Vehicle profile

Correction Services

Correction services have been operational in the market for 30 years delivering clock and orbit corrections over the L-Band or IP for land, airborne and near-shore applications. Our redundant infrastructure provides the reliability that autonomous vehicles require for safe operation.

TerraStar X Technology

TerraStar X correction technology eliminates convergence time while providing high accuracy global positioning to enable instant lane-level accuracy in autonomous applications. Available through cellular networks, TerraStar X will position vehicles with 5-centimeter accuracy in under a minute. When combined with GNSS receivers, this technology allows automotive customers to evaluate positioning performance in real-time.

How Does TerraStar Corrections WorkFeatures:

  • Delivers lane–level (<50 cm) accuracy throughout entire coverage area in less than one minute
  • Scalable for high volume of users
  • Received through either GNSS or over IP/Cellular
  • Reliability and available for 24/7/365 all-weather operations
  • Lower bandwidth requirements vs. RTK

TerraStar X Technology Testbeds

Evaluate the benefits of TerraStar X technology for precise localization in automotive applications at test beds across North America and in Europe. Trial networks are currently available in California, Arizona, and Michigan over satellite or cellular network, and in Germany using cellular delivery. Commercial solutions designed uniquely for the automotive market will be available in 2019.
