Fifth-generation SAASM-based design Dual- or single-frequency (L1/L2) tracking Enhanced Direct-Y code acquisition/cold start 12-channel all-in-view tracking and navigation No need for active antenna electronics Field-reprogrammable software Designed for high-g vibration and shock High-speed serial interface SAASM extended functions including black-key Field clock recalibration for extended storage
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.
