Faced with the regular challenge of harsh GNSS environments, VRT needed a solution that could provide robust positioning and orientation to aid in their underwater inspections.
VRT partnered with Applanix to design the perfect solution. VRT has two survey vessels that use Applanix POS MV to produce position and orientation solution.
In addition, VRT uses POSPac post-processing software to ensure the best quality data is achieved. Specifically, the IN-Fusion SmartBase and IN-Fusion SingleBase processing methods are used to improve the position and orientation solution, allowing noise point filtering and manual cleaning to become easier and more efficient.
If the survey area is accessible by the surveys vessels, VRT has 100 per cent confidence that POSPac provides the high quality data needed for inspection.
Even in extreme GNSS-environments like in urban canyons or beneath the bridge where GNSS data is completely lost for some time, POSPac has always made it possible to save the data.
“The improved data quality helps inspectors to make better observations and to be more confident about the information,” says Ville Mäkeläinen, Chief Business Development Officer at VRT.
