    Abstract: The disclosure relates to estimating an initial position and navigation state associated with a vehicle using odometry and/or other data obtained from the vehicle to support dead reckoning at start-up. In particular, a last known position and last known heading at a first odometer value associated with the vehicle may be stored and compared to a current odometer value after linking a mobile device with the vehicle. The last known position and last known heading may be used to estimate the initial position and navigation state associated with the vehicle based on a difference between the compared odometer values. For example, the estimated initial position and/or navigation state may substantially correspond to the last known position and last known heading if the difference between the odometer values indicates no change, or a non-zero difference may define a radius to limit an estimated error associated with the initial position estimate.

    Abstract: The disclosure generally relates to determining position of a motorized vehicle using wireless techniques. Methods, apparatus and systems are disclosed. A method can include: receiving absolute positioning data; receiving, from a mobile device, at least one of gyroscope data and odometry data; receiving, from a vehicle, at least one of gyroscope data and odometry data; initializing at least a heading to determine a relative path, wherein the relative path is based at least in part on the received data from the mobile device and the vehicle, wherein the received data comprises gyroscope data and odometry data; and shifting the relative path to an estimated path, wherein the estimated path is based at least in part on the absolute positioning data.

    Abstract: Various arrangements for determining a location of a base station without timing synchronization are presented. A mobile device may determine that it is moving faster than a threshold velocity. The mobile device may capture a first unsynchronized time of arrival (TOA) measurement and determine an associated first location, wherein the first unsynchronized TOA measurement is based on a first unsynchronized timing measurement of a first received reference signal. The mobile device may capture a second unsynchronized TOA measurement and determine an associated second location, wherein the second unsynchronized TOA measurement is based on a second unsynchronized timing measurement of a second received reference signal. Based on the mobile device moving faster than the threshold velocity, the first location, the second location, the first unsynchronized TOA measurement, and the second unsynchronized TOA measurement may be used for determining the location of the base station.
