mode, the high resolution spectral mode and a combi-
nation of multispectral with one of the stereo channels.
Because of the different figure in altitude the ground
pixel resolution results in 5.2 - 6.1 m for the high reso-
lution panchromatic channel and 15.9 - 18.2 m forthe
lower resolution channels.
The camera with its data recorder will be mounted
on top of the segment PRIRODA. One further compo-
nent for this mission is a NAV-package allowing GPS
positioning with an accuracy of about +- 5 m and at-
titude determination with an accuracy of +- 9 arcse-
conds. The data takes during that preparational mis-
sion should allow mapping and updating of GIS data
bases. The operation scenario should be as follows: data
takes will be made on demand by the users; the recor-
ded data are transmitted to earth via parabolic an-
tennae to Neustrelitz near Berlin and to Moscow. It is
expected that this scenario can fulfill several require-
ments on earth observation data.
6. CONCLUSIONS
The MOMS programme of Germany is up to now very
successful. About 30 Million DM have been spent for
camera development and instrumentation — not too
much in comparison with activities of the Landsat pro-
gramme of The United States and the French Spot fa-
cilities. The camera itself has the highest ground pi-
xel resolution of a digital space sensor ever flown; its
along-track stereo capability allows for photogramme-
tric stereo restitution and automatic DTM generation.
Furthermore, as shown by first data processing, the
optimization of the width of multispectral bands leads
to clear separation of vegetation, which could not be
solved as efficient as desired in the recent past. The
MOMS Science Team is very optimistic to obtain the
accuracies predicted.
Integration of photogrammetric and remote sensing
data in GIS is a necessity. Therefore, as shown by the
MOMS example the cooperation of different experts in
the disciplines of photogrammetry, remote sensing and
geographic information systems has led to a develop-
ment capable to manage geometric (stereo) and thema-
tic (multispectral) data acquisition simultaneosly. The
integration of the processed data in GIS can be done in
different ways: a simple strategy is the layer oriented
storage of different thematics — as far as DTM orga-
nization is concerned a more rigorous way is a total
merge of planimetry with the DTM data. The MOMS
programme is the optimum example of synergy; it is
expected that during processing of the MOMS02/D2
data and MOMS02/P data further details for earth ob-
servation will be worked out which will have influence
on further sensor design and permanent monitoring of
the earth surface from space.
