    "The report contains the design and building of 15 mancarried and 5 helicopter receivers that are 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." - NIOSHTIC-2
