Integrated GPS Anti-Jam System (IGAS)

822-2093-002

Overview

Accuracy is paramount when launching weapons in the field. Your mission success and the safety of your troops depend on it. Rockwell Collins has proven expertise in delivering reliable, accurate navigation products for precision-guided missile and munitions systems. The Integrated GPS Anti-Jam System (IGAS) is no exception.

The IGAS is the first integrated GPS and Anti-Jam system in the proven family of Rockwell Collins munitions receivers. The receiver utilizes 24-channel dual frequency all-in-view navigation, offering high performance GPS for tightly coupled GPS/INS (Global Positioning System/Inertial Navigation System) integrations. It is derived from the field-proven 12-channel NavStrike™ and Joint Direct Attack Munitions (JDAM) receivers. IGAS is a low-cost, small-size, high-accuracy and highly reliable system that has been specifically designed to meet the mission needs of missile and munitions applications.
