The report covers the Man Carried and Helicopter Receiver Portion of USBM Contract H0242010. This portion of the contract consisted of the design and building of 15 mancarried and 5 helicopter receivers used for trapped miner location during a mine disaster. Helicopters are equipped with six-channel receivers and used to detect transmitters carried by miners during a mine disaster. Immediately after a disaster a helicopter is flown over the area and, with the aid of the helicopter receiver, coarse location and the active channels are determined. Final precise location is made with the single-channel mancarried receiver.
