drift to within extremely close limits. In addition, the output of these systems is pro- 
cessed in computers — analog or digital - to bring them in a form usable either by the 
automatic pilot or by the camera orientation elements recorder, or by both. Whether 
these complicated systems will become of value for civil photogrammetry must become 
apparent in the future.
