Process and apparatus for target or position reconnaissance

Abstract

Items of relative target location information (19) which are obtained on board a platform serving as a sensor carrier (13) for target or position reconnaissance are combined, with association with the navigation satellite system time (34), with items of absolute mission location information (25) which are obtained on board the sensor carrier (13) from the satellite navigation orbit data (22), in order to obtain absolute target position data in which however, due to the system, there is still contained the absolute residual error of the order of magnitude of some ten meters, from the satellite-aided mission location determination. In order that the absolute target position data can also be made still more precise later, for effective use of the artillery (27), at a geodetically accurately known reception location (28) the deviation (33) between the location coordinates (32) and the items of reception location information (29) obtained on different platforms (13) and/or at different times and put into intermediate storage can also still be corrected at a later time by the deviations (33) associated in respect of system time, in order to obtain absolute target position data (36) which are independent of the satellite navigation residual error, for example for comparing the knowledge from the different, even time-displaced reconnaissance missions, for controlling the artillery (27).
