A method and system for estimation of the current location of a remote radio beacon, at a mobile device, based on two historical positions thereof provided via at least two satellite relays and one base station, particularly usable for Search and Rescue. A beacon is configured to periodically transmit short RF signals, relayed by a first satellite payload to a base station, at which the position of the beacon is resolved; then, the base station transmits a message, relayed by a second satellite payload and detectable by a mobile device, encoding two previous positions of the beacon, stamped with time tags. Finally, the mobile device decodes the information about said two previous positions of the beacon, and accordingly estimates the current position of the beacon, accounting for possible different time references.

A system and method for autonomous distress tracking of an aircraft. An automatic dependent surveillance-broadcast transceiver is configured to transmit an automatic distress transmission. A system controller comprises a distress identifier that is configured to determine when the aircraft is in a distress condition. The system controller is configured to control the automatic dependent surveillance-broadcast transceiver to transmit the automatic distress transmission in response to a determination that the aircraft is in the distress condition. The automatic dependent surveillance-broadcast transceiver and the system controller are contained within a housing attached to the aircraft on an outside of the aircraft.

Systems and methods for providing timely location estimates when a user equipment initiates a call to an emergency number are disclosed. The system enables a user equipment and network nodes (e.g., eSMLC/LMF) to send multiple location responses instead of just one so that the PSAP can benefit from accurate location techniques in a timely manner. For example, when a user equipment is located in an outdoor environment, it can immediately send its A-GNSS location after meeting quality-of-service (QoS) criteria, and the eSMLC/LMF can forward the location estimate to the PSAP immediately without first waiting for all of the other location estimates. When location estimates become available from other technologies (e.g., E-CID, or DBH, or both), the eSMLC/LMF can send to the PSAP another location response for that technology. As a result, the PSAP can always have the most accurate and up-to-date location information available to timely and accurately respond to emergency calls.

The disclosure is directed toward a communication system having a mobile device using a gesture-based user interface. The mobile device may include a user interface that is configured to accept gesture-based commands from a user and relay important information to a responder server during emergency situations.

Embodiments of the present invention address deficiencies of the art in respect to navigation in GPS-enabled mobile computing devices and provide a novel and non-obvious method, system and computer program product for location-based tsunami alerting navigational instructions in mobile computing devices. In an embodiment of the invention, a location-based tsunami alerting data processing system can be provided. The system can include a central processing unit coupled with a memory component, and a visual display along with location-based navigation logic that is enabled to compute a geographic zone of danger resulting from a tsunami, identify a geographic location for a mobile computing device corresponding to a subscriber, and render a set of personalized navigational instructions in the mobile computing device responsive to a determination that the subscriber is located in the geographic zone of danger.

Embodiments described herein provide means by which a civic location of a target mobile device may be determined using crowdsourced information from other mobile devices. The information can include information regarding Access Points (APs) and/or other access nodes obtained by the other mobile devices, as well as respective locations of the other mobile devices. A server, for example, can use this information to determine a coverage heatmap for each AP. Coverage heatmaps can be used, along with civic location information, to determine a civic location of a target mobile device based on the target mobile device's detection and possible measurements of wireless signals from one or more of the APs.

An autonomous distress tracking system for an aircraft is described. The system can include a transponder configured to transmit radio frequency (RF) emissions and an RF detector unit configured to detect the RF emissions. The system can further include an alert system that is in communication with the RF detector unit and be configured to activate a distress radio beacon if no RF emissions are detected within a predetermined period of time.

A location system and applications therefor is disclosed for wireless telecommunication infrastructures. The system is an end-to-end solution having one or more location systems for outputting requested locations of handsets or mobile stations (MS) based on, e.g., CDMA, GSM, GPRS, TDMA or WIFI communication standards, for processing both local mobile station location requests and more global mobile station location requests via, e.g., Internet communication between a distributed network of location systems. The following applications may be enabled by the location system: 911 emergency calls, tracking, navigation, people and animal location including applications for confinement to and exclusion from certain areas, friend finder applications, and applications for allocating user desired resources based on the user's location.

Networkable digital life jackets and associated methods are disclosed. An example life jacket includes a state manager and a swarm manager. The state manager is configured to selectively operate the life jacket in one of multiple operational states of the life jacket based on data obtained from one or more sensors of the life jacket. The swarm manager is configured to form a swarm network including the life jacket and one or more other life jackets.
