Abstract
There is provided a velocity measuring system contained on-board a projectile. The velocity is determined by a microprocessor on-board said projectile that bases the computation on a measurement of the time required for the projectile to pass two fixed points along the gun barrel. The fixed points may be passive signal sources that do not require an external power supply. A high degree of velocity accuracy is achieved because the microprocessor calculation need not be completed during the projectile's traversal of the gun barrel.
