About the Course

Unlocking precise GNSS Network RTK and post-processed positioning

This course is no longer delivered

Please note that this three-day course has been replaced by a new two-day course High Precision GNSS using Post-Processing.

We are pleased to offer this three day course in conjunction with Leica Geosystems. This intermediate/advanced course provides practitioners with theoretical / practical training together with best practice advice on the use of GNSS Continuously Operating Reference stations (CORS), e.g. Ordnance Survey's active network (OS Net) and SmartNet networks.

Through a series of practical and lecture sessions the key advantages of using CORS data within today's busy work schedules are covered. The third day provides an introduction to the rapidly maturing technology of network RTK from both a fieldwork (session included) and theoretical viewpoint.

Topics include:

  • Drivers for use of CORS networks
  • Reference system and transformation theory
  • Understanding and working with RINEX data
  • GNSS data processing and error handling
    • atmosphere
    • antenna phase centre variations
    • ocean tide loading
  • GNSS heighting
  • Overview of Network RTK theory
    • how it works
    • error mitigation
    • quality indicators
    • best practice guidance
    • ocean tide loading
  • Future directions for GNSS positioning
