Road based mapping

Robust and accurate mobile mapping over long distances

Road-based mobile mapping faces unique challenges compared to other types of surveying: 

  • The distances are far greater than a drone survey might cover. Surveyors need a way to protect the accuracy of their localisation data over those long distances, where IMU and GNSS drift could start to have a negative impact.
  • Urban mapping and similar activities cover areas with poor or even no GNSS signal. Surveyors need tools to provide continuous localisation accuracy even in those areas, to ensure the usability of the final survey data.
  • Urban mapping and similar activities cover areas with poor or even no GNSS signal. Surveyors need tools to provide continuous localisation accuracy even in those areas, to ensure the usability of the final survey data.

The OXTS solution for road-based mobile mapping

Using an OXTS localisation solution for road-based mobile mapping means you get precision and accuracy for the full length of your survey, whatever environment your vehicle travels through. From open skies to urban surveys, our solutions can help. 

  • 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, with form factors suitable for mounting on drones.
  • Mobile mapping-specific capabilities
    Unlock specific features in your GNSS/INS such as advanced gx/ix processing, external data logging, compatibility with our specialist georeferencing software, and our unique new LiDAR Boost capabilities for enhanced accuracy in GNSS-denied environments.
  • Software to make your project easier
    As well as our free NAVsuite applications for configuring and monitoring your GNSS/INS, we have mapping-specific tools including OXTS Georeferencer and our boresight calibration tool.
  • Accessories
    Mounting struts and dual antenna roof mounts ensure that your survey results are the best they can be.

GNSS/INS features for road-based mobile mapping

Road-based surveying requires an additional level of precision, even in areas where GNSS signal is limited like urban spaces. The following optional features are all included in the LiDAR mapping feature bundle: 

  • Advanced gx/ix tight-coupling – Speeds up RTK reacquisition after transient but complete GNSS outage meaning more accurate navigation data for longer (see example below).
  • PTP and gPTP time synchronisation – Master and client functionality makes it easier to integrate your GNSS/INS into an existing system.
  • External file logging – log data to an external storage device for longer missions.
  • OXTS Georeferencer – use Georeferencer to quickly and easily georeference your point cloud data, and to calibrate your LiDAR and GNSS/INS coordinate frames to remove point cloud blurring and double vision.

gx/ix™ tight-coupling processing 

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.

Tools for your project

01

OXTS Georeferencer

Quickly and easily combine localisation data from your GNSS/INS with raw LiDAR data to create georeferenced point clouds, and precisely calibrate your LiDAR and GNSS/INS for crystal clear point cloud data. 

02

LiDAR Boost

An advanced solution that uses data from any 32-laser, 360° LiDAR to compensate for missing or erroneous GNSS updates, either in post process or in real time. LiDAR Boost gives you better quality localisation data in GNSS-denied environments for georeferencing your survey data. 

03

NAVsuite

  1. Configure your OXTS GNSS/INS. 
  1. Monitor the navigation data from your GNSS/INS in real time.
