  • One application domain in particular namely a dormant awaken emergency device, does not have any real time or time zone information and it remains thus without positioning FIX while moving further away from an accident position. Delay in having a positioning estimation FIX degrades the accuracy of the accident position and the accident moment estimations.

  • a flying emergency device such as an emergency rocket, an emergency balloon, or an emergency drone
  • this integration may provide a line of sight visibility communication to cellular network base stations and positioning satellites from various heights. Height of the flight path of the balloon may be controlled by height information, and with processor generated controls to adjust the amount of gas in the balloon.
  • the line of sight visibility as such improves the received communication quality and positioning signal strength due to less attenuation in the radio path and signal quality due to less reflections and thus, less multipath propagations in the radio path, such as in the proximity of the surface of the earth, or in relation to hills and forest across the canopy.
  • the path loss behavior is linear and the path loss behavior shift is loga- rithmic when the distance to the earth increases.
  • the advantage is that a logarithmic path loss enables a longer base station reach than the linear path loss.
  • the bigger probability for an increased number of visible positioning satellites enables a faster FIX and more accurate positioning estimation.
  • a valley or an island may block the modem access to the cellular network. From higher altitudes, even without any line of sight visibility between the device antenna and the base station antenna, the cellular network coverage will be increased remarkably in the point of view of the emergency eCall message delivery.
  • a low band 2G (Second generation cellular system) cellular reach is up to 30 km in an earth surface position depending on the radio path conditions, but in higher altitudes above the same earth surface position, the line of sight radio path enables a connection length of even more than 70 km to a base station.
  • the cellular network reach also enables requesting an assisted GNSS ("Global Navigation Satellite System") positioning data from the network, which enable quite instant positioning after the assisted GNSS positioning data are received.
  • an advanced GNSS receiver may be used for having a technology to receive and use ionospheric delay corrections for received positioning signals and/or multi-frequency receivers, such as L1 and L2 frequencies (frequencies for positioning signals) or the like.
  • Such corrections may be delivered via a cellular network, via a local network or via a satellite, which enables improved positioning estimate accuracy.
  • this positioning delay brings with it an undesired impact on the position accuracy of an accident place due to the emergency device movement between the launch and the satellite position estimation FIX.
  • the drift is impacted by the delay, the direction of the wind vector, and the strength of the wind vector.
  • the device will move further away approximately 1000 meters.
