MOMS
Full Name: Modular Optoelectronic Multispectral Scanner
Phase: Past
Launch Date: June 18, 1983
The Modular Optoelectronic Multispectral Scanner (MOMS) is a scanning
system (based on CCD technique) for airborne and predominantly spaceborne
geoscientific remote sensing application. The first version MOMS-01
(with a dual channel mode: 600 nm and 900 nm) has been developed by
order of the German Minister for Research and Technology under contract
from the German Aerospace Research Establishment (DLR, previous DFVLR)by
Messerschmitt-Boelkow-Blohm (MBB). Scientific guidance for the experiment
has been provided by the University of Munich/FRG.
Most important characteristic of MOMS is the modular arrangement
of the CCD-sensor, electronics, optical lens system and filters that
allow the instrument to be adapted for completely different geoscientific
tasks or missions, as well as the refurbishment of the system between
missions as demonstrated in practise.
The multispectral mode of the MOMS family envisages geoscientific
data application for: general geologic mapping, mineral resources
exploration, hydrology; mapping and monitoring of renewable resources
(agriculture, forestry, urban and regional planning); coastal zone
monitoring; topographic mapping with conventional methods.
The first two flights of the space qualified MOMS-01 took place
on board of Space Shuttle with the missions STS-7 in June 1983 (total
recording time: 26 min) and STS-11 in February 1984 (total recording
time: 30 min). The sensor was placed with magtape recording unit (HDDT)
on the SPAS-01 platform, built by MBB, which was loosely connected
to the Shuttle by a specific bus system for system control. Both
flights yielded high-resolution images with 20x20 m ground pixel size
from about 300 km orbital altitude. Data takes are available over
Africa/Arabia, Australia, East Asia, India, South America, South East
Asia, and USA.
Data processing, archiving of products and their distribution to
users is made by the German Remote Data Center (DFD) in Oberpfaffenhofen,
FRG. Data products include CCT copies (1600,6250 bpi), film negatives
and B/W paper copies (scale1:800000) and appropriate image enlargements.
