Effect of Data Latency upon Missile Accuracy
Abstract
This study examined the effect of data latency upon air-to-air guided missile accuracy. This research was done by modeling a digital guided missile, inserting the model into a computer simulation and generating miss distance statistics. The digital guided missile was modeled after the DIS microcomputer architecture. The DIS (Digital Integrating Subsystem) approach involves a number of loosely coupled microprocessors which communicate over a serial multiplex bus. It was developed at the Air Force Armament Lab., Eglin AFB, FL. The missile simulation, Tactics IV, involves three degrees of freedom and is written in Fortran IV. It was developed by Science Applications, Inc in conjunction with AFWAL/FIMB, Wright Patterson AFB, OH. The results of this study indicate that typical data latency values generate only small increases in miss distance. The maximum delays tested were .01 seconds and the average increase in miss distance was 2.12 feet. Additionally, it was discovered that the transmission rate of the DIS microcomputers greatly affected miss distance. Microcomputers transmitting at 10 HZ generated large miss distances, even without data latency present. The identical missile engagements using transmission rates of 100 HZ resulted in much smaller miss distances.
