Abstract
A remotely controllable signal device, such as a buoy which may be used as target for gunfire training includes platform, a radio receiver, a decoding device, and one or more visual location signaling devices. The platform is floatable in the case of a buoy. The visual location signaling devices provide a visual indication of the location of the device. The visual location signaling devices include smoke generating devices such as marine smoke canisters, and a light such as a strobe light. The light can be mounted on a short tower for higher visibility. The decoding device can be a dual-tone multiple frequency decoder, and can include a switching device which selectively activates one of a number of visual location signaling devices located on the platform. The radio receiver may be a UHF AM receiver. The platform can also include a Global Positioning System transceiver device to assist in tracking the platform in the open ocean. As another option, the platform can include a sonar pinger to allow acoustic tracking of the impacts of shells when implemented as a buoy on instrumented hydrophone tracking ranges.
