Abstract
Abstract Optronic tracking and guiding instruments are maintained in a readiness state by simulating various conditions including mechanical loads and, possibly, temperature variations for obtaining a set of corrective data which is then used for compensating possible errors during a real live mission. The compensation involves particularly focusing and exposure time control.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
96 words
Method for ensuring readiness of an optronic instrument that is used for tracking and guiding comprising the steps of: providing for tracking operations of simulated objects, including focusing and exposure control under a variety of different conditions including variable inertia forces and temperature variations expected to occur during a real mission; ascertaining deviations in the focusing and exposure control from desired and required values including ascertaining any exceeding of permissible ranges; and providing compensating data being used on a running basis during the real mission for purposes of corrective control of the focusing and exposure control.
Claim 2
Dependent Claim
96 words
Method for ensuring readiness of an optronic instrument that is used for tracking and guiding comprising the steps of: providing for tracking operations of simulated objects, including focusing and exposure control under a variety of different conditions including variable inertia forces and temperature variations expected to occur during a real mission; ascertaining deviations in the focusing and exposure control from desired and required values including ascertaining any exceeding of permissible ranges; and providing compensating data being used on a running basis during the real mission for purposes of corrective control of the focusing and exposure control.
Claim 3
Dependent Claim
51 words
Method as in claim 1, including adjusting steps, the method being practiced also during tests and simulated runs the ascertaining steps alternating with the adjusting steps during test and simulated runs for purposes of iteration, thereby preparing the equipment for a real mission in which the simulated test run conditions recur.
Claim 4
Dependent Claim
31 words
Method as in claim 1, including providing correction and compensating data, said data being used directly in real life missions for corrections whenever previously simulated conditions occur during a live mission
