(U) This category addresses the handheld receivers that utilize signals from the DoD NAVSTAR GPS system. Systems described provide position information on the surface of the earth and, in some cases. with two-way, over-the-horizon data communications with low probability-of-intercept and anti-jam features.
(U) The DoD product line for portable GPS receivers began with the manpack, followed by a number of other receivers that utilize the GPS system. Handheld GPS receivers use integral fixed reception pattern antennas. Some handheld sets are equipped with an antenna which can be rotated to allow optimal reception, allowing variation in receiver orientation. Others have a built-in antenna which requires that the handheld receiver be properly positioned for optimal signal reception. All handhelds can be used with a remote antenna for vehicular installations. See individual systems for detailed descriptions.
