Real Time Kinematic (RTK)
MyRTKnet is the infrastructure that has been formed by the Global Navigation Satellite System (GNSS) reference stations and Control Centre to provide the GNSS data in order to give the position in real time. MyRTKnet service has been developed in 2003 that consist of 27 GNSS reference stations throughout the country. In endeavor to give a better service to the user, another 51 GNSS reference stations have been established by Department of Survey and Mapping Malaysia (DSMM) in 2006 until 2008 and the total number of reference stations now are 78 stations.
50 GNSS reference stations are located in Peninsular Malaysia whilst 28 stations in Sabah and Sarawak. The distance between the stations is from 30 to 150 km. The stations track GNSS signals and send them via dedicated data lines to a central network server at DSMM Geodesy Section, which manages and distributes GNSS correction data to subscribers in real time. Right now, the centimeter accuracy can be achieved to all users in Peninsular Malaysia, Kuching (Sarawak) and Kota Kinabalu (Sabah). The user also can get the DGPS correction anywhere in Malaysia as long as the telecommunications coverage is there.
The MyRTKnet service provides the data as stated in table below. The data that have been supplied to the user comprising of real time and post-processed data depend on the objective of work. The post-processed data consist of RINEX and Virtual RINEX data. The data can be downloaded via DSMM website in interval from 0.1 to 60 seconds. In order to get a good result, user should follow the Director General Circular No. 9/2005 which can be viewed in DSMM website.
