Abstract

The navigation solution of a device may be enhanced by perforating multiple pass smoothing. Forward and backward processing of the input data may be performed to derive interim navigation solutions. One or more quantities of the interim navigation solutions may be combined to smooth the quantities. At least one additional pass of forward and backward processing may then be performed using quantities of the navigation solution that were combined to enhance the interim navigation solutions. Next, at least one uncombined quantity of the navigation solution from the enhanced interim navigation solution is combined to provide an enhanced smoothed navigation solution. Additional passes may be performed to combine other quantities of the navigation solution as desired.

Description

[0001] Cross reference of related patents [0002] The claims of the present invention have priority over and benefited from the US patent application number 15 / 054,792 filed on February 26, 2015 by the patentee of the present invention, entitled "METHOD AND SYSTEM FOR MULTIPLEPASS SMOOTHING) "The invention application. Technical field [0003] The present disclosure relates to a method and system for enhancing the navigation solution of a device, and more specifically to a technique for performing multi-pass smoothing. Background technique [0004] Portable electronic devices, such as those configured to be handheld or other devices associated with users, are widely used in different application scenarios and environments. Increasingly, such devices are equipped with one or more sensors or other systems for determining the position or movement of the portable device. In particular, devices such as smartphones, tablets, smart watches, and other portable devices may have features o...
