RTK GPS technology takes global navigation satellite systems to the next level, enabling centimetre-level real-time accuracy for a wide range of professional applications. By utilising carrier phase measurements, real-time correction of errors, relative positioning and high update rates, RTK systems achieve a precision far beyond basic GPS. RTK is a sophisticated technique that enhances GPS data to achieve centimeter-level accuracy. It hinges on the interaction between several critical elements: GNSS inaccuracies, RTK receivers, and RTCM (Radio Technical Commission for Maritime Services) correction data. 1. GNSS Inaccuracies. GNSS systems, while globally operational, are subject GPS 機構では、これらのGPS基準局運用を通じて蓄積された海上測位技術のノウハウを平成18 年に「港湾・空港におけるRTK-GPS利用ガイド」としてとりまとめました。. 今般これを再整理し、要点を簡略化するとともに新たな知見も加え、「港湾空港GPS利用手引 These four lines enable the four RTCM output messages needed for a second GPS-RTK to receive correction data. Once these sentences have been enabled (and assuming a survey process is complete) the GPS-RTK base module will begin outputting RTCM data every second after the NMEA sentences (the RTCM_1230 sentence will be output once every 10 seconds). RTK updates to the vehicle will begin immediately. Once RTK data is being processed by the vehicle's GPS, its status will change to "RTK float" and then to "RTK fixed" in the GCS HUD indicating that it is ready for use. "RTK float" means that it is using correction data, but has not moved to the highest precision mode yet.
