Oxford Technical Solutions (OxTS) has released an article discussing the important points for obtaining survey and pointcloud accuracy from a surveyor’s perspective. OxTS Product Engineer Jacob Amacker, assesses modern surveying technology and identifies contributions to final errors in point positions and ways to combat them. The following technology is discussed:
- IMU Accuracy
- GNSS Localisation
- GNSS Constellations
- Inertial Navigation Systems
- Boresight Calibration
- Accuracy Calculation
The article identifies sources of error resulting from complex systems used by surveyors and explores survey data’s sensitivity to angular errors when surveying over a long range. The importance of IMU specification and reliability and the measured relations between surveying equipment is also discussed, alongside making use of the information available to estimate and analyse errors throughout a survey and identify areas that may require additional attention.
