Doppler/Global Positioning System Navigation System (DGNS)

The AN/ASN-128B DGNS provides a combined GPS/Doppler navigation capability through the embedding of a six channel GPS receiver into the signal data converter of the currently fielded AN/ASN-128 doppler navigation system. This system will reduce pilot workload and increase situational awareness by providing a precise navigation system. Considered a cost effective approach, the doppler with embedded GPS was recommended by a Draper Laboratory Study commisioned by PM-AEC. The 128B is the objective solution for the UH-60 & CH-47 fleet.
