Eristav GPS võib suurendada GPS-i täpsust umbes tuhat korda, vähendades määramatust umbes 15 meetrilt (1 kuni 3) sentimeetrini.
Hea teada
Eristavad GPSid koosnevad fikseeritud asukohaga maapealsete tugijaamade võrkudest, kus iga tugijaam arvutab erinevuse oma ülitäpse teadaoleva asukoha ja vähem täpse satelliidilt saadud asukoha vahel.
A differential GPS for GPS can increase accuracy by about a thousandfold, from approximately 15 metres to (1 –3) centimetres.
Hea teada
Differential GPSs consist of networks of fixed position, ground-based reference stations, where each reference station calculates the difference between its highly accurate known position and its less accurate satellite-derived position.
