precise tie image points complement the insufficient MOLA
geometry. With these precise measurements, MOC exterior
orientations are adjusted. The mis-registration of MOLA that is
around 325 meters along the flight direction is removed so that
MOLA profiles are registered to the same position on the two
stereopair images. Results from all of the three study sites
support this conclusion. Consequently, the proposed bundle
adjustment can overcome the scarcity of Martian ground
control points by a combined processing of MOLA and MOC
data under one unified mathematical frame. Our study suggests
that handling MGS data collected at considerately different
dates may be problematic due to the large inconsistency in the
trajectory data.
