RTCM SC-104, or often simply the RTCM standard, is a communication protocol for sending differential GPS (DGPS) to a GPS receiver from a secondary source like a radio receiver. The standard is named for the Special Committee 104 of the Radio Technical Commission for Maritime Services (RTCM) that created it.
What is RTK GPS used for?
GPS RTK, or Real-Time Kinematic, is a GNSS/GPS technique used to enhance the precision of position data received from satellite-based positioning systems.
How does differential GNSS work?
DGPS (Differential GPS) is essentially a system to provide positional corrections to GPS signals. DGPS uses a fixed, known position to adjust real time GPS signals to eliminate pseudorange errors. DGPS has no effect on results that are based on speed data, such as brake stop results.DGPS (Differential GPSDifferential GPSA Differential Global Positioning System (DGPS) is an enhancement to the Global Positioning System (GPS) which provides improved location accuracy, in the range of operations of each system, from the 15-metre (49 ft) nominal GPS accuracy to about 1–3 centimetres (0.39–1.18 in) in case of the best implementations.https://en.wikipedia.org › wiki › Differential_GPSDifferential GPS - Wikipedia) is essentially a system to provide positional corrections to GPS signals.
