%X This paper describes the Brazilian Environmental Data Collection System status and future planning actions to improve and to guarantee the system continuity. This system started its operation in 1993 with the successful launch of the first Brazilian satellite, SCD-1. The system concept is based on in situ land or sea data acquisitions by automatic platforms that collect the environmental data and transmit them to the satellite. The satellite acts as a mirror, retransmitting the received messages to a ground receiving station. The messages received at a station are sent to the Data Collection Mission Center for further processing, data store and dissemination to the users. Today more than 800 platforms are installed in the system and whose data are being used by 100 organizations. This paper also presents results and discussions over the system use, the main applications as well as the efforts being done to increase system performance and system continuity. The experience of system operation shows that major difficulties are related to the platform maintenance in the field, increasing number of new applications with demanding characteristics and difficulties to finance the development and launch data collection oriented satellites as SCD-1 and SCD-2, although all CBERS satellite series and all scientific satellites should carry on board a data collection transponder payload. The efforts in international cooperation with similar system are also presented and discussed.
