DGPS; 1. GPS stands for Global Positioning System. DGPS stands for Differential Global Positioning System. 2. In GPS, frequency varies from 1.1 GHz to 1.5 GHz. While in DGPS, frequency varies as per agency requirements. 3. GPS uses WGS84, that is used for time coordinate system. While in DGPS, local coordinate system is used. 4. The cost of GPS So, the difference between RTK and DGPS is that DGPS is the traditional differential GPS. RTK is a specific type of DGPS. but it uses a newer technology than the traditional DGPS. RTK stands for real-time kinematic and commonly uses the RTCM protocol. The traditional DGPS uses an older antiquated protocol while RTK uses a newer algorithm, and Global Positioning System (GPS) adalah sistem radionavigasi berbasis ruang angkasa yang memungkinkan pengguna dengan alat receiver baik di darat, laut atau di udara, untuk menentukan posisi mereka, juga dapat menenghitung kecepatan dan waktu kapan saja, siang atau malam, dalam cuaca dan kondisi apapun. The primary difference between GPS and DGPS is that GPS has a worldwide coverage area for its equipment, yet, the DGPS's instruments range is local. GPS GPS (Global Positioning System) offers the accurate position of an object to the earth. GPS makes use of timely messages produced by satellites revolving around the earth. Differential GPS (DGPS) uses a network of fixed, ground-based reference stations to find the location relative to a fixed point of reference. It depends on two receivers i.e reference and rover receiver where reference receiver is the stationary receiver which is fixed to a certain position and is known to the system whereas rover is the user. survey pemetaan dan informasi geografi . Sistem GPS, yang nama aslinya adlah NAVSTAR GPS (Navigation Satelite Timing and Ranging Global Positioning System), mempunyai tiga segmen yaitu : satelit, pengontrol, dan penerima / pengguna. Satelit GPS yang mengorbit bumi, dengan orbit dan kedudukan zvLHwB.
