The RBMC is a set of geodetic stations equipped with high-performance GNSS (Global Navigation Satellite Systems) receivers, which provide observations for determining coordinates or transporting coordinates once a day or in real-time. This information is used in GPS survey processing software as a basis to improve the accuracy of observations, as it serves to "tie" your points to the geodetic system with well-defined coordinates.
IBGEThe RBMC has been providing files with a tracking interval of 1 second in RINEX 3 format since January 1, 2020. Detailed information about the publication and instructions for editing these data can be found below in Information on 1 Second Data. Data with a tracking interval of 15 seconds in RINEX 2 and RINEX 3 formats from all RBMC stations continue to be made available in the same manner, without changes, in HATANAKA compression, and in RINEX 3 format, only for stations with multi-constellation equipment.
