    摘要: Method and apparatus of increasing location accuracy of an inertial navigational device is described. The inertial navigation device generates real-time data and transmits the real-time data to a second device so that the second device may obtain a location of the inertial navigational device. The inertial navigational device receives an update message from the second device, wherein the update message is created at the second device based on a comparison of the real-time data generated by the inertial navigational device against a magnetic field database and adjusts the depicted location of the inertial navigational device based on the update message in order to increase the location accuracy of the inertial navigational device.

    摘要: A radio beacon (105(5)) is for use in location determination inside a building (103) or other enclosure. The beacon transmits a RF signal equivalent to a partially coded GPS (Global Positioning System) signal which includes an identity code identifying the beacon but null data in at least one GPS data field. A mobile station (101) includes a GPS receiver (208) for receiving GPS signals and a processor (202) for processing data extracted from signals received by the GPS receiver. The GPS receiver is operable to receive a signal from a transmitting beacon (105(5)). The processor is operable to recognise a beacon identity code from the data extracted from the received signal and thereby detect that the signal is from a radio beacon rather than a GPS satellite and thereby to apply a further procedure to calculate the location of the mobile station based upon a known location of the identified beacon.

    摘要: A system (400, 500) and method (800) of personal inertial navigation measurements can include measuring (802) an angle, measuring (804) an angular velocity independent of an angle measurement, measuring (806) an angular acceleration independent of the angle measurement and independent of an angular velocity measurement, and combining (808) the angle measurement, the angular velocity measurement, and an angular acceleration to provide an angled output. The angle measurement can be measured using a compass or magnetic field, the angular velocity can be measured using a gyroscope (such as a MEMS gyroscope), and the angular acceleration measurement can be measured using an angular accelerometer (such as a molecular electronic transfer device having a magneto hydrodynamic effect device). The method can further include suppressing (810) noise caused by the angle measurement by using a sample and hold circuit (504) controlled by a higher ordered component to suppress noise from a lower ordered component.

The processor can be further programmed to form (320) a new context vector based on the context transition and attempt to match the new context vector with a pre-stored context vector.
