Servicing a Non-visible Target in the Real World
Use location data but no precisely measured
The problem: An artillery piece shoots at a target coordinates provided from an external source.
The shooter has its location in some coordinate system, e. g. Augmented TM.
The target coordinates may be known to some accuracy in lat, lon & geodetic height.
The fire control system may or may not require conversions to another coordinate system, for example a LTP CS.
The fire control system computes firing angles based on its internal mechanization and may model wind, air density and other environmental parameters.
The round impact and miss distances are observed by a forward observer who feeds information back to the firing site.
The process is completed when the impact error is small enough.
