SinoGNSS Devices Show Superior Performance in CORS Construction in Maldives
With the development of GNSS and surveying industry, the CORS (Continuously Operating Reference Stations) is becoming widespread worldwide. Compared with the traditional surveying method and normal 1+1 GNSS surveying, CORS network equips the following advantages.
- Cost-efficient: Comparing with the normal 1+1 rtk survey mode or static mode that requires at least 2 units of GNSS receivers. The CORS mode only need one unit, which greatly saves the cost of surveyors.
- Reliable Accuracy: For single-base mode, the nearest base station will be permanently set at a fixed location, which reduces the step of site calibration and eliminates the human error. As for VRS mode, it will provide more accurate calibration data to achieve higher measurement accuracy.
- Ease of work: Free of base station carrying and setup, the CORS mode simplifies the survey workflow and light the burden of surveyors.
Maldives, as a country where DGPS technology is widely used,has also joined the trend and started the construction of CORS. Foresight Surveyors, partner of ComNav Technolgy, who has been largely involved in the development and expansion of current day survey industry in Maldives, has set forth to connect the Maldivian islands via a CORS network (MVCORS, Maldives Continuous Operating Reference Stations).
The project is carried out in coordination with Maldives Land and Survey Authority and with assistance of an international consultant to industry standard. The MVCORS installation project is planned to be completed in two stages. The first stage is scheduled to be completed by October 2021, which will install 9 reference stations throughout the Maldives and will eventually be used as a single network connection. The second stage plans to add 12 more stations on the basis of the first stage.
M300 Plus GNSS receivers and AT600 choke ring antennas of ComNav Technology were used in the CORS reference stations construction. Featuring the strong satellite tracking capability of GPS, GLONASS, BeiDou, Galileo and QZSS, the M300 Plus can provide stable and high-precision correction streams to CORS users. Meanwhile, the web server of M300 Plus facilitate the configuration and management of the CORS provider.
With the hard work our partner and contributions of SinoGNSS devices and technicians,so far three reference stations have been successfully built up in Maldives, which are located in Seenu Hithadhoo, Laamu Gan and HDH Kulhudhufushi, providing stable and accurate CORS service to surveyors. And the remaining stations of the first stage are under active construction and will be put into use soon.
To simplify people’s work and make the world better is the driving force behind ComNav Technology. ComNav Technology is dedicated to be an innovator and leader in high-precision GNSS technology and explore more applications.
