2 DAYS
This course is for surveyors and engineers who need to gain a greater understanding of GNSS theory, survey and data processing. The bias is towards collecting and post processing static GNSS data for Control installation.
Tuition is also provided on setting up a GNSS Base station and performing a site calibration.
Guidance will be provided during the baseline processing segment regarding acceptable error margins and the utilization of precise ephemeris data. Additionally, the network adjustment session will involve refining shorter occupation points to align with longer occupation points. Ordnance Survey RINEX data will be employed to adjust the longer occupation points to precise coordinates, ensuring accuracy and consistency throughout the process.
Through this training, participants will be equipped to handle GNSS equipment more effectively, understand the technicalities of GNSS data processing, and mitigate common sources of error in GNSS surveying.
