L-3 Interstate Electronics has announced its latest miniaturized GPS receiver. The TruTrak Evolution receiver is a single board L1/L2 24-channel secure GPS receiver that electronically pinpoints exact locations for navigation and tracking purposes.
The receiver's advanced technology increases the performance and accuracy of precision guided projectiles, munitions and land attack missiles under development in various government programs.
The TruTrak Evolution receiver consists of a security module, radio frequency down converter and I/O logic.
The receiver provides significant cost, size and power reduction improvements, which are needed to successfully incorporate a complete navigation system into the small physical space available in the munitions. The receiver's direct deep integration technology supports direct acquisition and tracking in jammed signal environments.
In addition to Position, Velocity and Time (PVT), the TruTrak Evolution receiver also provides area navigation. It features a very accurate time source for radio Time Division Multiple Access (TDMA) operation and specialized power management modes to optimize battery life, which are essential in portable handheld devices.
The receivers are designed and tested to survive rugged environmental conditions while maintaining exact performance requirements, such as precision timing within 10 microseconds. The receivers' Mean Time Between Failure is greater than 25,000 hours. The JPO approved security design provides a Time-to-First-Fix in less than 6 seconds (no jamming) and obtains stabilized measurements even in high-jamming environments.
The receiver employs the latest KDP II SAASM chipset in the XFACTOR module to provide enhanced GPS security. The XFACTOR SAASM module is a secure tamper-resistant, multi-chip module that decodes the Department of Defense GPS Precise Positioning Service Signal. The TruTrak receivers also support the SAASM extended functions.
