The news was announced on July 23 at a meeting of the Ministry of Natural Resources and Environment’s Agency for Survey and Mapping held to report the results of the project to build a network of satellite-based global positioning stations in Vietnam.

The stations will provide GPS data to support accurate positioning not only in map surveys but also in transport, geophysics, construction and agriculture.

According to head of the agency Phan Duc Hieu, the network of stations established by the project will help detect movements of tectonic plates, improve weather forecasting and provide data to the national target programme on climate change response.

The application of GNSS has proven effective with co-ordinate deviation of less than 5 centimetres, he said, adding that more than 280 organisations and individuals have registered to use the service so far and the number will increase when the stations become operational in the central and southern regions.

Vietnam is planning to build 160 CORS that will apply GNSS.
