  • GPS Surveying - Point Positioning

    Credits: 2 PDH

    PDH Course Description:

    This course covers the general concepts of performing absolute/autonomous point positioning and discusses some of the inherent errors associated with this process. The GPS was originally designed to provide point positioning and velocity for users, either through absolute or autonomous positioning with a single hand-held GPS receiver. This method is widely used for real-time navigation and location in military and commercial applications. However, it may not be accurate enough for precise surveying, mapping, or hydrographic positioning due to potential errors.

    Topics:

    • Absolute or Autonomous Point Positioning
    • GPS Absolute or Autonomous Position Solution Process, Pseudoranging
    • GPS Point Positioning Accuracies
    • Positional Accuracy Statistics, Root Mean Square
    • GPS Range Error Budget
    • User Equivalent Range Error
    • Satellite Geometry Effects on Accuracy, Dilution of Precision
    • Resultant Positional Accuracy of Point Positioning
