a lack of ballistic programs at the time, custom simulations were written in Mathcad to solve for numerous flight variables. In addition to modeling the flight, the interior ballistics were modeled by continuously altering polynomial curves until they were in agreement with publicly available data. Due to a lack of available terminal ballistics data that would have been representative of the guided bullet, the data was compared to that of large game hunting bullets. Changing trajectory One kind of smart bullet is a projectile that is capable of changing its course during flight. One use of this would be to enable soldiers to stay behind protective cover and shoot around corners. One implementation uses a spoiler and micro gyro to control the bullet. Navigating Honeywell Aerospace has produced inertial measurement units based on MEMS and microelectronics technologies that it claims can survive the shock of being fired out of a gun. Transmitting data It has a low range coverage. Another smart bullet is one that can transmit data about the location into which it has been fired. A prototype has been created by researchers at the University of Florida in Gainesville, Florida, USA with funding from Lockheed Martin. The bullet (projectile) has a sensor inside of it that can send wireless data up to 70 meters. Notes References Smart devices Ammunition Weapon guidance Emerging technologies
