Abstract
A device of a supplementary navigation satellite is provided. The device includes a unit for generating navigation signals, the signal strength of the navigation signals being dimensioned in such a way that it is still possible to receive signals of other satellite navigation systems.
Claims12
A device of a supplementary navigation satellite comprising:
- a unit for generating navigation signals, wherein the signal strength of the navigation signals is dimensioned in such a way that it is still possible to receive signals of other satellite navigation systems, and wherein the signals transmit navigation-relevant information at a data rate which is significantly above the data rate of the Galileo satellite system,
- wherein the navigation-relevant information comprises at least one of current and expected traffic obstructions in a service area, recommendations for how specific user groups having various travel directions and travel destinations, which may be regionally combined, are to drive around these traffic obstructions, changes of the street grid in the service area, and expected traffic obstructions due to environmental influences.
A method for transmitting a navigation signal comprising:
- generating navigation signals, wherein the signal strength of the navigation signals is dimensioned in such a way that it is still possible to receive signals of other satellite navigation systems, and wherein the signals transmit navigation-relevant information at a data rate which is significantly above the data rate of the Galileo satellite system;
- and
- transmitting the generated navigation signals,
- wherein the navigation-relevant information comprises at least one of current and expected traffic obstructions in a service area, recommendations for how specific user groups having various travel directions and travel destinations, which may be regionally combined, are to drive around these traffic obstructions, changes of the street grid in the service area, and expected traffic obstructions due to environmental influences.
