Abstract	(?)	The Brazilian Environmental Data Collection System provides data collection services based on SCD-1 and SCD-2 satellites to an increasing user community. The SCD-1, in spite of 19 years in flight operation, is operating in a degraded mode as well as SCD-2 with 14 years in operation continues to offer 24 hours/7 days data relay function to more than a 1000 platforms. Several effort actions to improve the ground infrastructure to receive and to process the relayed messages have being performed. A Data Collection Processor, named PROCOD, is a ground receiving station equipment that process the down linked relayed frequency band and recover the messages transmitted from the data collection platform networks. A new PROCOD version was developed and installed in the Cuiaba ground station by mid-2012. The development cycle follows the traditional space project phases, starting from specification to acceptance tests and field validation. The exceptional performance obtained with PROCOD III version during field tests in Cuiaba ground station is presented in this paper, as well as the concepts used in the design. This equipment employs digital processing technology, field programmable gate arrays components and more than 20 years of INPE experience in ground equipment development. The measured operational results show a 121% improvement in message recovery compared to PROCOD-II for SCD-1 passes and an 85% improvement for SCD-2. Although these exceptional results obtained, a new PROCOD version is being in discussion to meet demands for increasing numbers of platforms and applications.
