EXPLORE OUR RANGE

Unmanned but not unguided

Localisation is a vital component of any UAV control system – whether you’re building a short-range drone or a long-range UAV navigation system. In either use case, a UAV positioning system needs to deliver accurate location, heading, pitch, roll and yaw data in a wide variety of environments including GNSS-denied environments. It’s also important to find a localisation system that’s commercially viable, especially if you’re building UAV navigation systems for clients.

UAV navigation solutions

For short-range craft, the size, weight and power ratio of your UAV navigation system is especially important in order to maximise mission times. For longer-range craft, the ability to withstand aerospace conditions is vital in order for your UAV navigation system to survive the mission.

Working with OXTS gives you access to hardware, tools, and capabilities to build a robust localisation solution for any UAV navigation project.

  • Smooth, high-quality PNT data from ITAR-free hardware
    Our GNSS/INS devices use careful calibration, sophisticated sensor fusion and an advanced navigation engine to deliver highly reliable data in a variety of environments.
  • Autonomy-specific features
    Unlock specific capabilities in your GNSS/INS such as Hot Start initialisation and PTP synchronisation.
  • Software to make your project easier
    As well as our free NAVsuite applications for configuring and monitoring your GNSS/INS during build and test, we have autonomy-specific tools including ROS2 drivers designed to remove complexity from your project.

GNSS/INS features for UAV navigation

To create an attractive and commercially viable autonomous UAV, you need robust navigation and user-friendly features. The following optional features are all included in the autonomy feature bundle: 

  • gx/ix tight-coupling – Speeds up RTK reacquisition after transient but complete GNSS outage meaning more accurate navigation data for longer (see example below).
  • Hot Start initialisation – enables your GNSS/INS to initialise while stationary, even without a GNSS signal, so your AMR can initialise indoors and navigate outside by itself.
  • PTP and gPTP time synchronisation – master and client functionality makes it easier to integrate your GNSS/INS into an existing payload.
  • UCOM data messaging – gives you more control over your data outputs to simplify your architecture, increase safety, and more.

GNSS vs OXTS gx/ix tight-coupling technology…

An OXTS INS can integrate single-satellite aiding data into its navigation solution, and reduce the time taken to reacquire RTK lock, in real time. Using NAVSolve, you can reprocess your raw data and still benefit from gx/ix tight-coupling processing.
