Anwendungsbeispiel: Lokalisierung von Denkmälern auf einem Feld mithilfe von GPS-Geräten

Surveyors are tasked with determining the location and elevation of two monuments in a park using the Global Positioning System, or GPS technology. 

The survey begins with mission planning. Using the software, the team identifies optimal satellite visibility, ensuring low Position Dilution of Precision or PDOP for accuracy. A 2-hour window with strong satellite coverage is selected.

A geodetic control point serves as the base station. At this point, the team sets up a GPS receiver and records the antenna height.

A rover GPS receiver is positioned near each monument's site. Obstructions like trees are cleared to maintain a clear satellite view.

Data is collected using the static GPS method, with 30-minute observations at each site. PDOP values are monitored throughout to ensure optimal accuracy.

The surveyors use correction software to refine the raw GPS data, eliminating errors from ionospheric delays and signal multipath effects.

Elevation data is calculated using GPS-measured heights and geoid heights from geodetic models. The results are validated against known control point data for accuracy.

Final coordinates and elevations are documented, ensuring accurate survey records for the monuments.
