Geo-reference all simultaneously collected ROMDAS survey data with GPS coordinates. The system can also use the GPS data to establish location of the vehicle or road centre line. The geo-referenced data allows for easy integration with GIS mapping or asset management software.

From real-time submeter accuracy to Real-Time Kinetic (RTK) Base stations for up to 5cm GPS accuracy, ROMDAS system can connect with a range of GNSS configurations to suit specific accuracy needs and budgets.

Experienced operators of high-speed surveying equipment know the real-world limitations of collecting GPS where civilised constructions and environmental obstructions lead to GPS drop-outs. Correcting these GPS drop-outs or outages during quality control in post-processing can be time-consuming.

ROMDAS’ GPS with Inertial Navigation System (INS) is our standard and cost-effective solution for improved accuracy, and reliability, of your GPS data. It uses dual antennas to provide continuous stream of spatial data such as position, speed and orientation of the vehicle while it is traveling. This helps to fill-in the gaps during these GPS outages (Dead Reckoning) to provide navigationally useful information. The ROMDAS GPS with INS module increases reliability of your data to give you error-free location reference points, especially useful for mobile mapping and asset inventory.

ROMDAS System can output road geometry characteristics with a simple and Geometry Upgrade to your GPS with INS module. With this economical Geometry upgrade, the system will automatically calculate and record pavement gradient, radius of curvature, and cross-fall.

Using the GPS with INS dual antennas and sensors, the unit provides real-time output of vehicle pitch, roll and yaw for accurate positioning and orientation while traveling. This information is displayed in ROMDAS data collection software at the time of survey which helps to calculate the road geometry.

Road geometry data and the data referenced with GPS coordinates, is essential for accurate mobile mapping. This collected data is easy to integrate with most commonly used GIS mapping software or Pavement Management Systems (PMS).
