You have 365 days left.


Unlike static GNSS positioning methods, real time procedures require the geospatial practitioner in the field to perform the data collection correctly with a knowledge of conditions and methods that will affect their results. This course will point to NGS guidelines for best methods in both a single base scenario as well as with using real time networks (RTN) to achieve precise and accurate data collection. Techniques that can give increased confidence with the field work will be presented and a summary table with specific criteria for achieving four different precisions at the 95% confidence level will be highlighted. Ultimately, the control is at the pole.


Upon completion of this course, the student will be exposed to:
• Using the NGS Real Time Guidelines
• Navigating the “Seven C’s” of field methods:
- Check (Equipment)
- Communication
- Conditions
- Constraints
- Coordinates
- Collection
- Confidence
• Summary & the four cardinal rules
