Global Positioning System (GPS) Overview
• Initiated in 1973, maintained by DOD • A minimum of 24 satellites in the constellation
provide world-wide “coverage” 24/7 • Minimum of 4 satellites need to be tracked
and processed by a receiver for XYZ • Various accuracy levels for receivers:
– Consumer grade ~ 15 meters and better – Resource grade ~ 1 meter and better – Survey grade ~ Centimeter

GPS Applications
• Navigation – Fishing/hunting spot, geo-cache – Locate features or stake points
• Geospatial Data Collection – Recreational – Collect a waypoint! – Resource grade – Collect GIS features – Survey grade – Collect benchmarks and topo

Errors in GPS
• Obstruction • Multi-path (esp. off of chain-link fences) • Atmospheric conditions • Clock bias • Receiver hardware • User

Key GPS Requirements
• Line of sight to satellites is critical – No visibility = no GPS positions – Poor visibility = poor GPS accuracy
• Antenna placed at feature to be captured • Differential correction for accuracy
– Correction sources depend upon receiver type and accuracy capabilities
• Vertical accuracy is ~ 1.5 – 2 X horizontal

Laser Mapping Applications – The Keys
• Map where satellites cannot be “seen” at all or where GPS reception is poor
• Map hard/impossible to reach spots – Across a river channel
• Map multiple features from a single position
• Add height, range and azimuth as attributes
