The Universal Target Systems Ltd (UTSL) airborne Miss Distance Indicator (MDI) Scoring
System is part of the MSAT-
The MDI Scoring System is used against all calibres of shell and can typically sense the projectile out to a range of 10 metres (32 feet). When a shell passes through the sensing zone its generated shock wave is picked up by the sensors mounted in the front nose cone. The trigger data is added to the live telemetry stream. This telemetry data is received by the telemetry receiver, decoded and sent to the computer which processes the data and displays and records the information in an easy to understand and simple interface. Missions can be recorded together with ballistic and any other information, a print out of which can be made for post firing analysis.
The MDI Scoring System is made of only 3 main components; the airborne transceiver, the ground based receiver and its separate computer. The system is robust, easy to use and maintain. The airborne equipment is water proof and maintenance free. Except the computer, which must be housed in a normal controlled environment, the rest of ground equipment is completely weather proof.
