Abstract
A first position (104) of the mobile client is determined at least in part by utilizing first signals received from at least one first signal source. The first signal source operates in a first location determination system (114). A second position (106) of at least one second signal source (120) is determined by utilizing both the determined first position of the mobile client and second signals received from the at least one second signal source (120). The second signal source (120) operates in a second location determination system. A third position (116) of the mobile client is determined utilizing the second signal source (120).
Claims11
A method of seamlessly determining successive positions of a mobile client comprising:
- determining a first position of the mobile client at least in part by utilizing first signals received from at least one first signal source, the at least one first signal source operating in a first location determination system;
- determining a second position of at least one second signal source by utilizing both the determined first position of the mobile client and second signals received from the at least one second signal source, the at least one second signal source operating in a second location determination system;
- and
- determining a third position of the mobile client utilizing the at least one second signal source.
A mobile client comprising:
- an interface, the interface adapted and configured to receive first signals from at least one first signal source that operates in a first location determination system and second signals from at least one second signal source that operates in a second location determination system;
- and
- a controller coupled to the interface and that is adapted and arranged to determine a first position of a mobile client at least in part by utilizing the first signals from the at least one first signal source and that is further adapted and arranged to determine a second position of at least one second signal source by using both the first position and the second signals from the at least one second signal source.
