A new national positing systemDRUK CORSNet was launched by the National Land Commission yesterday.

According to the National Land Commission Secretariat (NLCS), it is a significant milestone in the national positioning system was reached with the launch of this system. It consists of a network of nine ground stations with a command center in Thimphu that track global navigation satellites and transmit real-time correction signals to users 24/7.

The existing network located in Thimphu, Phuentsholing, Gelephu, Deothang, Kanglung, Lhuentse, Bumthang, WangduePhodrang and Dagana provide coverage to most of the settlements in the country.

New stations are planned to be built in Ha, Samtse, Zhemgang and Gasa in the coming financial year to achieve nationwide coverage.

It states that this new system will provide a couple of centimeter accuracy in real-time, which meets requirements of most surveying applications. As of now, close to 200 users from government, corporation and private sectors have subscribed to the CORSNet. Users apply the technology in diverse fields in cadastral, topographical, engineering, geophysical, mining, resource mapping, geodynamics and academic research.

Besides providing an automated quality control and quality assurance system for surveying, real-time kinematic surveying based on CORSNet presents tremendous efficiency gains compared with other modes of surveying.

According to the NLCS, in the coming years it inspires to introduce network RTK and virtual reference system to further enhance the accuracy and reliability of CORS service.

The Land Act 2007 and the Geoinformation Policy 2018 of the Kingdom of Bhutan require all surveying and mapping to be based on the national geodetic datum. DRUKREF03 is the existing national geodetic datum. Surveys with ties to DRUK CORSNet will by default yield coordinates based on DRUKREF03.
