MMRS (Multispectral Medium Resolution Scanner)

The MMRS, Multispectral Medium Resolution Scanner is a five channel camera with detection capability in VIS, NIR and SWIR ranges. On-ground pixel size is 175 m and spectral bands were selected to fit land and coastal study requirements.
On board stored and real time operation modes outline the mission. In addition a Data Collection System (DCS) allows the use of both, images and Data Collection Platform's data, together in order to enhance the data use.
INVAP is the prime contractor for the design, construction and testing of the MMRS. Optical design tools and special clean optical laboratories were acquired and are at present fully operative at Villa Golf INVAP facilities for the development of this tasks. Thermal-vacuum and vibration test facilities are also available at INVAP facilities.
The goal of MMRS is to bring to the scientific community a remote sensing system specially suited for studies in great extension areas, such as plains and forestry of the American continent.
MMRS is the main instrument of SAC-C (Scientific Applications Satellite) CONAE's satellite which is scheduled to be launched in May 1999 with a 4 year lifetime .SAC-C is planned for heliosynchronous circular orbit and 9 days of revisit time, with 702 km nominal altitude, 97.8° inclination and 97 min orbital period.
MMRS observations will help to visualize the dynamics of desertification processes in Patagonia and the results of experiments carried to minimize it, the land usage in productive areas, flood processes (NW of Buenos Aires Province), forestry analysis, coast contamination and water chlorophyll contents, among others. 

MMRS is a space scanner pointed to bring assistance in land uses, however two bands have been included to generate helpful information for coastal applications.
