Some Abbreviations and Definitions
CORS Continuously Operating Reference Station - An installation of GNSS receiver that is precisely located and continuously observing GNSS data. Arrays of CORS are often linked together as part of a network to deliver precise positioning solutions over large areas.
DGNSS Differential GNSS - A basic method of processing GNSS data to achieve submeter level accuracies (often referred to as DGPS).
GNSS Global Navigation Satellite System - A global network of satellites producing navigation signals for positioning and navigation applications on earth.
VRS Virtual Reference Station - A method of NRTK which generates virtual data from data collected at nearby CORS for a specified location.
MAC Master Auxiliary Concept - A method of NRTK which provides CORS data with correction parameters generated from nearby CORS in order to optimise the solution for a specified location.
NRTK Network RTK - An enhancement of RTK which utilises data from multiple CORS to provide a uniform level of accuracy across the network.
NTRIP Networked Transport of RTCM via Internet Protocol - A method for streaming RTCM messages over the internet.
RINEX Receiver Independent Exchange - An international standard for the storage of GNSS data.
RTCM The Radio Technical Commission for Maritime Services - An international standard for real-time data streaming of GNSS data.
RTK Real Time Kinematic - A sophisticated method of processing GNSS data to achieve centimetre level accuracies in real time.
