  • Patent number: 9606241
    Abstract: Sensor-assisted location technology is disclosed. Primary location technologies, such as GPS, can be used to determine the current location (e.g., a location fix) of a location-enabled device. In some instances, the primary location technology may be unreliable and/or consume more power than an alternative location technology. Sensors, such as accelerometers, compasses, gyrometers, and the like, can be used to supplement and/or increase the accuracy of location data. For example, a location-enabled device can identify an area with unreliable GPS location data and use sensors to calculate a more accurate location. Areas identified may be crowd-sourced. Sensors can be used to identify errors in the location data provided by primary location technology. Sensors can be used to modify a sampling interval of the primary location technology. Sensor can be used to smooth motion on a user interface between sampling intervals of the primary location technology.

  • Patent number: 9000977
    Abstract: Global Navigation Satellite Systems (GNSS), such as the US GPS, the European GALILEO and the Russian GLONASS are very limited indoors, due to very low power levels and significant multipath. So, though hundreds of millions of people around the world use GPS receivers, particularly embedded in mobile devices, they cannot use these devices indoors, where they stay most of the time. Present art methods for augmenting or assisting GPS indoors, are mainly based on cellular or WLAN networks, and embedded sensors such as accelerometers and compasses, yet no integrated solution was launched. The present invention discloses a method that may contribute to GNSS indoors navigation, enabling a GNSS receiver to measure its elevation above sea level, indoors, to a floor resolution. The disclosed method is based on terrestrial infrastructure, yet possibly only one beacon per building.

  • Patent number: 8442765
    Abstract: A method for collaborative navigation comprises initializing a conditionally independent filter on a local platform, propagating the conditionally independent filter forward in time, and when a local measurement has been made, updating the conditionally independent filter with the local measurement. When a common measurement has been made, the conditionally independent filter is updated with the common measurement, and a determination is made whether a remote conditioning node has arrived from a remote platform. If a remote conditioning node has arrived, a determination is made whether the remote conditioning node needs to be fused with a local conditioning node of the conditionally independent filter. If the remote conditioning node needs to be fused, a node-to-node fusion is performed in the conditionally independent filter to merge the remote conditioning node with the local conditioning node to produce a merged conditioning node.

  • Publication number: 20130099962
    Abstract: Global Navigation Satellite Systems (GNSS), such as the US GPS, the European GALILEO and the Russian GLONASS are very limited indoors, due to very low power levels and significant multipath. So, though hundreds of millions of people around the world use GPS receivers, particularly embedded in mobile devices, they cannot use these devices indoors, where they stay most of the time. Present art methods for augmenting or assisting GPS indoors, are mainly based on cellular or WLAN networks, and embedded sensors such as accelerometers and compasses, yet no integrated solution was launched. The present invention discloses a method that may contribute to GNSS indoors navigation, enabling a GNSS receiver to measure its elevation above sea level, indoors, to a floor resolution. The disclosed method is based on terrestrial infrastructure, yet possibly only one beacon per building.

  • Patent number: 8339311
    Abstract: A multi-standard single chip integrated within a multi-standard mobile device concurrently receives multi-standard radio frequency signals by corresponding two or more integrated radios. The multi-standard single chip generates full GNSS measurement comprising pseudo-range information using the received radio frequency signals. The multi-standard single chip comprises a GNSS radio and multiple non-GNSS radios such as Bluetooth. The full GNSS measurement is generated using GNSS radio frequency signals received by the integrated GNSS radio and communicated over, for example, Bluetooth radio. GNSS satellite reference information embedded in radio frequency signals received by the integrated non-GNSS radios is extracted to assist the full GNSS measurement. A full GNSS navigation solution for the multi-standard mobile device is generated internally to and/or externally to the multi-standard single chip depending on the location of a navigation engine.
