1. A method of indoor navigation using a mobile device, which method comprising:
- providing a map of anchors in a specific indoor area in which a mobile device is located;
detecting one or more anchors in said specific indoor area using an optical sensor of said mobile device;
measuring a rotational orientation of said mobile device using an orientation sensor, to determine a rotational orientation of said mobile device when performing said detecting said one or more anchors;
determining a spatial relationship between said one or more detected anchors and said mobile device, based on signals received by said optical sensor and said measured rotational orientation of said mobile device;
accurately determining a position of said mobile device within said determined specific indoor area using a map of anchors in said specific indoor area and said spatial relationship that was determined based on said measured rotational orientation.
