DESCRIPTION

The NavStrike™ 3.3 is the latest addition to the proven family of Rockwell Collins munitions receivers. Available with 12-channel all-in-view navigation that is backward compatible with the prior version, the munitions GPS card offers high performance for tightly coupled GPS/INS (Global Positioning System/Inertial Navigation System) integrations. It is derived from the field-proven Joint Direct Attack Munitions (JDAM) receiver.

The NavStrike™ 3.3 incorporates the advantages of the most advanced GPS technology: enhanced Direct-Y acquisition, all-in-view navigation, high jamming immunity, fast initial acquisitions, carrier loop aiding*, fast cold start and extended range correlation*.

The NavStrike™ 3.3's low cost, small size, high accuracy, and high reliability are key to mission success in missile and munition applications. NavStrike™ provides accurate GPS navigation either as a stand-alone system or when integrated with an existing INS or Doppler Reference System.

This embedded receiver module offers full Precise Positioning Service (PPS) accuracy. Simultaneous L1/L2 operation provides real-time ionospheric corrections for further accuracy enhancements. Its primary communication interface is a high-speed RS-422 serial port.

Modular design and field-programmable software ease maintenance, provide a growth path, and reduce life-cycle cost. Delivery is assured by using common critical components, processes and manufacturing lines that deliver over 100,000 Selective Availability Anti-Spoofing Module (SAASM)-based GPS receivers per year.
