RCVR 3A (R-2332( )/AR)

Most of the current DOD aircraft inventory are scheduled for integration with GPS JPO-procured 3A and MAGR. These receivers are fully mil-qualified and have undergone extensive developmental and qualification testing. Although the 3A receiver was developed in 1985, the receiver continues to perform well in the field; the receiver has only received a modest upgrade and is considered to be of “older technology.” It has 5 channels with which to receive & process satellites; the larger the number of channels, the faster the receiver computes the first fix and updates position. The Time to First Fix (TTFF) is important to the speed (or dynamics) of the host platform. The three primary functional shortcomings of the 3A receiver are that it is not field reprogrammable (in other words it must be returned to a depot for upgrade), it does not implement an enhanced anti-spoofing function (recognition and avoidance of deception - intentional or unintentional signal interference), and lastly it is large, heavy and contains many outdated/obsolete components. The depot at Warner Robins-ALC provides sustainment support for the 3A receivers and will continue in that role for the foreseeable future.
