What are ephemeris errors?
Focus on the definition of ephemeris.
True or False: Ephemeris errors can affect the precision of GPS positioning.
Remember how GPS accuracy is tied to satellite data.
A regional survey project uses GPS for infrastructure planning. Discuss the potential impacts if ephemeris errors are not corrected and suggest methods to minimize these issues.
Consider how important precise location data is for construction.
Evaluate a real-world scenario where inaccurate GPS data caused issues due to ephemeris errors. What lessons can be learned, and how would you propose to prevent such issues in the future?
Think about the context of accuracy in emergency situations.
