Abstract
Systems and methods are disclosed for providing a plurality of navigation solutions using a portable sensor device associated with a user. Motion sensor data may be used to derive a first navigation solution using the obtained sensor data under a first set of processing conditions navigation solution and to derive at least a second navigation solution using the sensor data under a second set of processing conditions, wherein the second navigation solution is refined as compared to the first navigation solution. As such, the second navigation solution may represent a more accurate or more complete solution, with the first navigation solution may represent a reduced expenditure of resources. The system includes the portable sensor device and optionally may include an auxiliary device associated with the user and/or remote processing resources. The functions associated with deriving the first and second navigation solutions may be performed by any one or any combination of the portable sensor device, the auxiliary device and/or the remote processing resources.
