Abstract

A computer program product corrects a detonation time from a ballistic table, based on the actual velocity of a projectile measured upon exit of the projectile from the gun tube. The computer program product transfers a 16-bit data stream, through a 16-bit to an 8-bit encoder, to a fuze controller implemented as an 8-bit platform, to provide precise timing adjustment to a fuze controller. The computer program product significantly improves the accuracy of detonation times for air burst mode. The encoder calculates the absolute truncated, square rooted, X, of the input time delay number, as well as the error correction number, Y. The encoder then transmits both numbers X and Y as an 8-bit data stream, optionally along with the parity data to the fuze controller.
