RBMC -Brazilian Network for Continuous Monitoring
Introduction
The use of GPS technology (Global Positioning) was a real revolution in this last decade, in the activities of navigation and positioning. The geodetic and topographic works can be done in a quicker, economic and more precise way. These advantages are providing great improvements, as equipment, observation methods and processing techniques evolve. It is in this context that RBMC is found.
In the GPS geodetic and topographic applications the use of the relative method is implicit. This means, at least one station of known coordinates is also occupied simultaneously to the occupation of the points of interest. Before the RBMC, the user interested in obtaining, with GPS, the geodetic coordinates of any point in the national territory, had to work with two receivers, occupying the point of interest and a close mark of the Brazilian Geodetic System.
The stations of the RBMC have the function of representing the point of the known coordinates, eliminating the need for the user to immobilize a receiver in a point, which several times, offers great difficulties of access. Besides this, the receivers which equip the RBMC stations are of high performance, providing observations of great quality and reliability.
Observation: we request RBMC users to quote in their works that the data were provided by IBGE, maintainer of the RBMC project. We also demand not to repass the data, but instead, inform other users interested to download the data through the IBGE’s website (RBMC) or to ask directly IBGE.
