image distortions uncommon in modem metric frame cameras.
On the other hand, temperature is expected to have an impact
on various optical characteristics of the Medusa instrument.
A thorough sensitivity analysis will be conducted at first. Block
bundle adjustment, in combination with a specific flight pattern
will be used to determine the significance of thermal effects on
the geometric performance and the system’s internal and
external calibration model.
