I'm struggling to understand why you think satellite data "cannot" be part of a scene reconstruction. Satellite data establishes things like distance, field of view, and clarifies what kinds of details would plausibly be known to the soldiers at the scene and what interpretations of events are more or less plausible. Geography of a landscape only changes over the scale of 100,000 years or more, over the time scales involved here satellite data is consistent.
