For surface mobility, Rockwell Collins’ GPS-based equipment is unsurpassed. Our portable, versatile GPS receiver provides precision guidance capabilities for vehicular, hand-held, sensor, and gun laying applications. The Defense Advanced GPS Receiver (DAGR) offers the smallest and lowest weight hand-held receiver for the war fighter, with an easy-to-use man-machine interface (Graphical User Interface (GUI) and moving-maps) and a proven design that passes environmental, serial port and software testing for a low risk, field ready unit.

The DAGR incorporates anti-jam improvements for enhanced protection and is the first U.S. handheld GPS receiver program to include the next generation security device, Selective Availability Anti-Spoofing Module (SAASM). The Rockwell Collins SAASM includes:

• Proven capabilities of the Rockwell Collins’ NightHawk 12-channel GPS signal processor
• All-In-View navigation using up to 12 GPS satellites
• Advanced correlator engine for accelerated Direct-Y code and C/A code acquisitions
• Next-generation security architecture using Key Data Processor (KDP-II)
• Unclassified-when-keyed operation and updated security features

The DAGR’s dual frequency RF front end allows continuous track of both the L1/L2 GPS satellite frequencies. Even when turned off, a precision time source (HAL) runs continuously to allow rapid acquisition of the GPS satellites when the receiver is turned on.

The DAGR website www.shopcollins.com/dagr provides information related to the hardware and operations of the DAGR. It also provides government access for more detailed information on documentation and training. Users of the DAGR can provide feedback to Rockwell Collins Engineering for potential future DAGR improvements. Links are also available to Customer Service for the DAGR.
