Macao Satellite Positioning Reference Station

In order to support the development of basic surveying and mapping services in Macao, improve the quality of measurement results and work efficiency, and promote the application of Global Navigation Satellite System (GNSS) in topography, geographic information collection, and relevant fields, Cartography and Cadastre Bureau of the Government of the Macao SAR established three satellite positioning reference stations in the Macau Peninsula, Coloane Island, and Taipa Island in 2002, 2006, and 2008, respectively, at an interval of 4-9km. The scope of services of the three satellite positioning reference stations covers the whole Macao.

Fortaleza do Monte GPS Reference Station (FOMO)

FOMO, built in 2002, is located to the east of the Macao Museum on "Fortaleza do Monte". It was the first all-weather satellite positioning reference station in Macao.

Coloane Alto GNSS Reference Station (COAL)

COAL, built in 2006, is on "Alto de Coloane", Estrada do Alto de Coloane.

Taipa Grande GNSS Reference Station (DSMG)

DSMG, built in 2008, is located on the top floor of the office building of the Macao Meteorological and Geophysical Bureau, the Macao SAR Government, on Taipa Grande.


All the three satellite positioning reference stations work 24hx7. They constantly receive the signals from the US GPS, the Russian GLONASS, and the Chinese Beidou Navigation Satellite System (BDS). Connected with the control center of the Macao Cartography and Cadastre Bureau, the three stations return the real-time signals received to the control center. After the data are processed and analyzed, the stations will provide the satellite positioning service required by the user to meet the requirement of precise satellite positioning and enhance the efficiency of measurement and satellite positioning.

In 2009, the Macao Cartography and Cadastre Bureau established Macao Satellite Positioning Reference Station Service (MoSRef) to further disclose the data of the satellite positioning system and offer automatic coordinate calculation function. In November 2012, the Macao Cartography and Cadastre Bureau introduced NTRIP. Through the mobile telecommunication network and NTRIP, the user can utilize the correction message provided by MoSRef and services like Differential Global Positioning Systems (DGPS) and Real-Time Kinematic (RTK) for positioning. The issue of failure to receive the MoSRef service in an environment with poor receipt of radio signals was solved. Moreover, the demand of user devices was reduced. Hence, satellite positioning services can be applied more widely.


Currently, MoSRef provides the following services:

1. Raw data download
2. Automatic coordinate calculation
3. Real-time positioning for measurement
  • DGPS
  • RTK
  • Network RTK
