Product Description
Summary
MyRTKnet is Malaysia's first and only nation-wide GPS network and system infrastructure developed for GPS users to provide RTK and DGPS services with unmatched accuracy and coverage for positioning applications across the country. As a wide-area satellite based service, the broadcast My RTKnet corrections can be obtained anywhere in Malaysia using a custom-built MyRTKnet GPS receiver. The positioning data from MyRTKnet reference stations is optimised for Malaysia, resulting in superior centimeter-level accuracy with most GPS receivers. MyRTKnet is provided exclusively by JUPEM using the advanced GPS technologies of Trimble GPSnet and the latest in cellular communications.
Its easy, step out onto the project site and start collecting data at survey grade accuracy in a matter of minutes. One person, one GPS rover and one high accuracy reference station network. Now, you can perform cadastral surveying, construction stakeout, topographic surveying, precision GIS data collection and machine control without setting up your own GPS base station and without paying an employee to man the base station. Thinking of a GPS purchase? With MyRTKnet you can now perform RTK operations with the purchase of just one rover. Your investment to implement RTK into your company and department has just been cut in half.
MyRTKnet will drastically increase your production and provides our customers a strategic advantage to complete projects more efficiently than ever before. Work Smart.
Description
The present coverage of MyRTKnet includes three dense networks that provide centimeter accuracy around Lembah Klang, Pulau Pinang and Johor Bahru, (Figure 1) and a sparse network covering the whole nation. Other areas in the vicinity of 30 km radius from the permanent reference stations will also provide centimeter accuracy. This coverage is expected to be further densified in the years to come as JUPEM endeavours to provide better extent of the facilities to GPS users.
MyRTKnet provides various levels of GPS correction and data. Their use will depend on the technique and application to be employed by the users. Virtual Reference System (VRS) data, Single Base data and Network Base DGPS data are meant for real time applications whereas Virtual RINEX and RINEX data are for post-processed applications.
In the usage of VRS data, the user must provide its approximate rover position to the control centre. This is done via cellular modem using the standard NMEA GGA string. The control centre automatically receives this positioning information, interpolates and applies corrections for ephemeris, tropospheric and ionospheric errors and generates the virtual reference station for that individual rover. It then produces a set of standard format correction messages as if they were coming from the virtual reference station and transmits them via cellular modem back to the rover.
This Single Base data is provided for areas within 30 km from any of the MyRTKnet single permanent reference station. The rover will select the reference station required through cellular phone connection and the corresponding differential data will be transmitted from the control centre to the rover.
The Network base DGPS data is provided for the whole of Peninsular Malaysia and areas within 150 km radius from Kota Kinabalu and Kuching. This could be utilized in applications such as sub-meter mapping and navigation. Any receiver that is capable of handling Real Time Corrections and cell phone data service can be used to receive DGPS solutions Real Time RTCM corrections. Distance dependant errors are eliminated for users observations due to DGPSs array of base station locations.
Virtual RINEX data are GPS RINEX format data generated by MyRTKnet system based on approximate coordinates provided by users. These data are the virtual reference station data and are available for downloading through the website which will be used as a reference by users for baseline computation. Similarly, the observed permanent reference station data in RINEX format are also available on the website. Data can be downloaded at any interval ranging from 0.1 second to 60 seconds.
Further information with regards to MyRTKnet usage, a user guideline has been provided through the Director General Circular No. 9/2005 which can be viewed at the JUPEMs website.
