Full Title

Satellite radio beacon positioning systems; Determining position, velocity or attitude using signals transmitted by such systems > Determining a navigation solution using signals transmitted by a satellite radio beacon positioning system > the satellite radio beacon positioning system transmitting time-stamped messages, e.g. GPS [Global Positioning System], GLONASS [Global Orbiting Navigation Satellite System] or GALILEO > Determining position > by combining or switching between position solutions derived from the satellite radio beacon positioning system and position solutions derived from a further system > whereby the further system is an inertial position system, e.g. loosely-coupled
