CBERS Data Collecting System

The CBERS-1, 2 and 2B satellites integrate the Brazilian Environmental Data Collection System which is based on satellites and on a data collecting platform (DCPs) network distributed over the country. This system aims to provide to Brazil environmental data collected daily in its different regions.

The DCPs are small automatic stations usually installed in remote locations. The data received from DCPs are transmitted to the satellites which retransmit in turn to a INPE ground station, in Cuiab (MT) and Alcntara (MA). From these stations, the data are sent to the Mission Center, located in Cachoeira Paulista (SP), Brazil, where the data are processed and distributed to the users.

The registered users receive the processed files using Internet at most 30 minutes after satellite pass.

The data collected by the satellites are used in several applications, such as CPTEC (Brazilian Center for Climate and Weather Studies and Forecasting) weather forecast, ocean circulation studies, tides, chemistry of the atmosphere, agriculture planning etc. More, than 600 platforms are installed in Brazil. One important application is the hydrological basin monitoring by the ANA and SIVAM platform networks, which provides Brazilian river and rain data.
