A method for locating a UWB transmitter, without a previously-set reference, using at least one first set of at least three UWB searching transceivers, including first, second, and third transceivers. The method a) synchronizes the three UWB searching transceivers, arranged at three different points, and estimates the relative position of these three points; b) receives, by the three transceivers, signals transmitted by the transmitter to be located; and c) calculates the relative position, with respect to the three searching transceivers, of the transmitter to be located according to the time of travel of the signals, transmitted by the transmitter to be located, to the three searching transceivers. A device for locating a UWB transceiver, comprising at least three searching transceivers, programmed to implement a method according to claim 1.
This precautionary recall applies exclusively to ORTOVOX 3+ avalanche transceivers running software version 2.1. 3+ devices running the following software: 1.0, 1.1, 2.0, 2.2 – no matter what color – and all other ORTOVOX avalanche transceivers (S1+, S1, ZOOM) are not affected. Jan 15, 2009 WildSnow Beacon Reviews Overview. August 2011 Update: For the 2011-12 season, the S1 becomes the S1+, with the ability to switch between two different transmission antennas, so as to avoid a worst-case vertical-plane transmission. This means that (as explained in more detail in my initial review for the Ortovox 3+) some scenarios for suboptimal searcher-victim coupling are avoided and hence.
