After ten years, the Department of Defense is developing and testing a replacement for its Precision Lightweight GPS Receiver (PLGR). The new unit, to be issued in 2004, is the Defense Advanced GPS Receiver (DAGR). While waiting for DAGR, many troops have taken advantage of the falling prices of GPS receivers and have bought their own. This has provided an extra incentive for the Department of Defense to develop a more capable update of the PLGR. The new unit will be more jamming resistant and a lot easier to use. Security requirement (special codes) for using the more accurate military GPS signals will be a lot more easy to handle. The display will be able to download maps and more effectively show the DAGR users where they are and where they are going. The DAGR will also work faster, getting location data in about a minute, versus about six minutes for PLGR. DAGR will be lighter (at two pounds) than PLGR (2.75 pounds.)
