Designers from Raytheon TI Systems in Dallas are choosing ruggedized global positioning system (GPS) receivers from Interstate Electronics Corp. of Anaheim, Calif., for the XM982 Extended Range Projectile program. This program seeks to extend the range and accuracy of the U.S. Army 155-mm howitzer shell. Interstate officials will deliver 393 engineering-development-model GPS receivers, which company engineers are designing to withstand the massive shock from a 155-mm cannon. The GPS receiver will provide vital navigation information immediately after the projectile fires.
