AL-3 Interstate Electronics Corp. (IEC) in Anaheim, Calif., is introducing two configurations of its anti-jam miniaturized, hardened, global positioning system (GPS) receiver and one configuration of its GPS-based navigation and guidance unit. The TruTrak Evolution GPS receiver configurations measure 1.75 by 2.45 inches and are low-power and high-accuracy. The embedded GPS receiver model for rugged systems, such as munitions and missile guidance, measures 3.07 by 0.93 inches. The TruTrak Evolution guidance and navigation unit (GNU) includes the receiver and dual-frequency MCM (TTE-DM) navigation, as well as user-process development tools. TruTrak Evolution units are single board, L1/L2 24-channel secure GPS-based systems that electronically pinpoint exact locations for navigation, guidance and control, and tracking. The receivers and GNUs are designed to meet the performance and low-cost requirements of today’s military applications. All are available in production quantities. The TruTrak Evolution uses less than 3 watts in its highest-performance operating mode; less than 700 milliwatts in low-power mode; and 20 milliwatts on standby.
