ASP Equipment delivers the Flight Model (PFM) of the EnMAP IPU to the instrument prime OHB-System AG in Oberpfaffenhofen, Germany.<\/p>\n\n\n\n
The German\nEnvironmental Mapping and Analysis Program (EnMAP) is a hyperspectral satellite\nmission that aims to monitor and characterize the earth\u2019s environment on a\nglobal scale. EnMAP serves to measure and model key dynamic processes of the\nearth\u2019s ecosystems by extracting geochemical, biochemical and biophysical\nparameters, which provide information on the status and evolution of various\nterrestrial and aquatic ecosystems.<\/p>\n\n\n\n
Unique is\nthe mission outline of a hyper-spectral range from 420 nm to 1000 nm (VNIR) and\nfrom 900 nm to 2450 nm (SWIR) with high radiometric resolution and stability in\nboth spectral ranges. <\/p>\n\n\n\n
A key role\nin enabling the extraordinary accuracy, resolution and stability requirements\nplays ASP\u00b4s contribution of the Instrument Power Unit (IPU). <\/p>\n\n\n\n
The IPU is\nfeaturing 2 ultra-precise Calibration Current Sources, multiplexed to eight\noutputs, several switched outputs, galvanic isolated switchable outlets up to\n10A, Latching Current Limiter functionality, 16 Heater Supplies and an UARTS\nbased RS-422 TM\/TC interface, supported through a space proof RTAX2000 FPGA.\nASP has challenged physical limits in the achievement of highest possible\naccuracy and stability of the provided electrical power outlets.<\/p>\n\n\n\n
The logical control capabilities of the IPU are developed to the extent to completely overtake the full thermal control of the EnMAP instrument, in cases where the board computer is booting or is non-operational through any other circumstances.<\/p>\n\n\n\n
