Definitions
- the present invention relates to a method and apparatus for locating a survivor; and, more particularly, to a survivor locating method and apparatus using a search and rescue beacon equipped with a navigation chipset.
- a typical search and rescue service is operated only by a beacon signal. It is designed to locate a survivor by receiving only a beacon signal of a search and rescue beacon in a low earth orbit (LEO) search and rescue satellite when a distress signal is generated, and measuring a distance based on Doppler effect.
- a two-dimensional (2D) location of the survivor can be acquired by measuring the distance at least twice. Since it takes about one hour and a half for the LEO search and rescue satellite to make a second visit, it takes quite a long time to determine an actual location.
- a 2 nd generation search and rescue system equipped with a navigation chipset is introduced in order to make up for the shortcomings.
- the 2 nd Generation search and rescue system can detect the location of the survivor more precisely than the LEO search and rescue satellite system using Doppler effect.
- the 2 nd Generation search and rescue system can detect the location of the survivor by using not only the LEO search and rescue satellite but also a geostationary search and rescue satellite.
- An embodiment of the present invention is directed to providing a method and apparatus for providing a locating service which can be provided in case that enough visible satellites are not acquired in a distress situation.
- An object of the present invention is to provide a service for locating a survivor continuously when a search and rescue beacon equipped with a navigation chipset does not have enough visible satellites in a distress situation. That is, another embodiment of the present invention is directed to providing a method and apparatus for determining a location of a survivor without delay by acquiring distance information based on Doppler effect with respect to a beacon signal of the search and rescue beacon, distance information by processing more than one navigation signal which is received by the navigation chipset of the search and rescue beacon.
- a method for locating a survivor using a search and rescue beacon equipped with a navigation chipset including the steps of: receiving a rescue signal from the search and rescue beacon through a search and rescue satellite; extracting distance information from the search and rescue beacon to a navigation satellite measured by the navigation chipset and information on the navigation satellite from the rescue signal; receiving distance information from the search and rescue satellite to the search and rescue beacon measured by the search and rescue satellite; determining a location of the search and rescue beacon by unifying the distance information and the navigation satellite information.
- an apparatus for locating a survivor using a search and rescue beacon equipped with a navigation chipset including: a communication unit for receiving a rescue signal from the search and rescue beacon through a search and rescue satellite and receiving distance information from the search and rescue satellite to the search and rescue beacon which is measured by the search and rescue satellite; a distance information extracting unit for extracting the distance information from the search and rescue beacon to a navigation satellite measured by the navigation chipset and information on the navigation satellite from the rescue signal; and a location determining unit for de- termining a location of the search and rescue beacon by unifying the distance information and the navigation satellite information.
- the present invention measures a distance by unifying distance information measured in the search and rescue satellite based on Doppler effect from the beacon signal of the search and rescue beacon and the distance information measured in and transmitted from the navigation chipset of the search and rescue beacon based on Doppler effect from more than one received navigation signal.
- the distance information measured by the navigation chipset is transmitted by the distress beacon signal with the information of the navigation satellite.
- a mode is converted into a normal locating mode.
- a survivor can be located in the presence of only one visible navigation satellite. It takes at least an hour and a half to locate the survivor according to a conventional method.
- speed and exactness in locating the survivor are limited as well.
- the method suggested in the present invention can improve the speed and the exactness.
- FIG. 1 shows a survivor locating apparatus and network connection in accordance with an embodiment of the present invention.
- FIG. 2 is a flowchart describing a survivor locating method in accordance with an embodiment of the present invention.
- Fig. 1 shows a survivor locating apparatus and network connection in accordance with an embodiment of the present invention.
