Ground Control Points (GCPs): Why They Matter in Surveying and Mapping
Every coordinate you collect in the field, every map you deliver to a client, every drone survey that gets turned into a usable deliverable rests

The Global Positioning System that launched as a military tool in the 1970s wasn’t designed with land surveyors in mind. For years after it became
Before GPS became a household word, surveyors spent days establishing control networks just to tie a single project to a known coordinate. Today, a surveyor
Before a coordinate ever lands in your field software, your GNSS receiver has already done something most surveyors never think about: it translated raw satellite
Every RTK receiver kit used to ship in pairs. One receiver went on the base, one went on the rover, and the accuracy of your
Most people picture surveying as someone standing behind a total station on dry land, but some of the most technically demanding survey work happens where
Before GPS existed, surveyors spent days establishing control networks just to get a handful of reliable points. Today, an RTK GPS system can deliver those
A GNSS receiver sitting on a tripod looks simple enough. Point it at the sky, wait for a fix, collect your data. But the difference
Most surveyors know their RTK system delivers centimeter-level accuracy. Fewer know exactly what’s happening in the radio spectrum to make that possible. Your GNSS receiver
