A power management method for a portable device including a global navigation satellite system (GNSS) receiver and a wireless transceiver includes: in a normal mode, sending at a first interval first location information obtained from the wireless transceiver to a central station in an emergency response system via the wireless transceiver, where the GNSS receiver is placed in a lower mode or a power-off mode; in an emergency mode, sending in a predefined sequence and priority the first location information obtained from the wireless transceiver and second location information obtained from the GNSS receiver to the central station via the wireless transceiver, wherein the GNSS receiver is placed in a full power mode; and in response to failing to obtain the first location information from the wireless transceiver at the first interval, entering the emergency mode and skipping sending the first location information to the central station.

Systems and methods for crash determination in accordance with embodiments of the invention are disclosed. In one embodiment, a vehicle telematics device includes a processor and a memory storing a crash determination application, wherein the processor, on reading the crash determination application, is directed to obtain sensor data from at least one sensor installed in a vehicle, calculate peak resultant data based on the sensor data, where the peak resultant data describes the acceleration of the vehicle over a first time period, generate crash score data based on the peak resultant data and a set of crash curve data for the vehicle, where the crash score data describes the likelihood that the vehicle was involved in a crash based on the characteristics of the vehicle and the sensor data, and provide the obtained sensor data when the crash score data exceeds a crash threshold to a remote server system.

A method and system includes the ability for individuals to set up an ad hoc digital and voice network easily and rapidly to allow users to coordinate their activities by eliminating the need for pre-entry of data into a web or identifying others by name, phone numbers or email. This method is especially useful for police, fire fighters, military, first responders or other emergency situations for coordinating different organizations at the scene of a disaster to elevate conventional communication problems either up and down the chain of command or cross communication between different emergency units. The method and system provides that the users are only required to enter a specific Server IP address and an ad hoc event name, a password and perhaps the name of the particular unit.

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.
