摘要： The present disclosure relates to a system and method for integrating online, dynamic wireless system modeling with a navigation solution. The building of wireless dynamic online models for wireless positioning does not require pre-existing information such as pre-surveys and is capable of providing relatively better accuracy. Integration of the wireless positioning using dynamic online models with other navigation systems/solutions is proposed whereby the other navigation system/solution can benefit and enhance the building of wireless dynamic online models. In addition, the wireless dynamic online models can be optimally integrated with the other navigation system/solution for enhanced positioning performance.

摘要： The present disclosure relates to a method and apparatus for determining the misalignment between a device and a pedestrian, wherein the pedestrian can carry, hold, or use the device in different orientations in a constrained or unconstrained manner, and wherein the device includes an optical sensor or camera. The optical sensors have a corresponding frame for the optical sensors' axes. The misalignment between the device and the pedestrian means the misalignment between the frame of the optical sensor assembly or camera in the device and the frame of the pedestrian. The present method and apparatus can work whether in the presence or in the absence of absolute navigational information updates (such as, for example, Global Navigation Satellite System (GNSS) or WiFi positioning).

摘要： The present disclosure relates to methods of enhancing a navigation solution about a device and a platform, wherein the mobility of the device may be constrained or unconstrained within the platform, and wherein the navigation solution is provided even in the absence of normal navigational information updates (such as, for example, GNSS). More specifically, the present method comprises utilizing measurements from sensors (e.g. accelerometers, gyroscopes, magnetometers etc.) within the device to calculate and resolve the attitude of the device and the platform, and the attitude misalignment between the device and the platform.

摘要： Devices and methods for providing an enhanced navigation solution are disclosed that involve detecting correction events along a trajectory of a device. Platform speed is estimated based on characteristics of the correction events, such as by estimating speed of turn during the turn of the platform so that a navigation solution is enhanced by correcting the trajectory of the platform using the estimated speed.

摘要： Systems and methods are disclosed for estimating speed and/or velocity for a portable device using an optical sensor. The optical sensor may capture a plurality of samples to be processed to estimate speed. The speed or velocity may be estimated based on a determined context and/or usage of the portable device. The estimated speed or velocity may be used to supplement other navigational solutions or may be used independently.
