    Abstract: Where each node device is assumed to know the time-of-day with an accuracy of only plus or minus 1 second, the geolocation of said node device is determined by an A-GNSS server by help of a time-stamp known with an accuracy better than or equal to 10 milliseconds and added by at least one transceiver of the asynchronous RF network. Indeed, the technical feature of said asynchronous RF network according to which the time-of-day at which data are sent from each node device is known in a deterministic manner allows the A-GNSS server to determine retrospectively this time-of-day in function and with the precision of the time-stamp added by said at least one transceiver to the data packet issued from said node device over the asynchronous RF network.

    Abstract: Described is a navigation solution calculation method and a user device. The method can include providing an assistance request to a server. One or more signal path signatures can be received from the server. The one or more signal path signatures can be associated with a first position of the user device. The one or more signal path signatures can be compared with one or more satellite signals received by the user device from one or more satellites. A second position of the user device can be determined based on the comparison.

    Abstract: Technology for determining a geographical location of a ground receiver is disclosed. A plurality of radio frequency (RF) signals from a plurality of RF signal carriers may be received at the ground receiver. The plurality of RF signal carriers may include satellites operated by a foreign entity or non-global positioning system (non-GPS) satellites. The ground receiver may measure a Doppler shift associated with each of the plurality of RF signals. The geographical location of the ground receiver may be determined in X, Y and Z coordinates based in part on the Doppler shift associated with each of the plurality of RF signals.

    Abstract: Low-energy consumption techniques for locating a movable object using a global navigation satellite system (GNSS) are provided. A mobile station attached to or included in a movable object can communicate bidirectionally with a fixed base station to determine a location of the movable object. The mobile station may communicate an estimated position to the base station and receive from the base station a set of GNSS satellites that are visible to the mobile station. The mobile station can acquire satellite timing information from GNSS signals from the set of satellites and communicate minimally-processed satellite timing information to the base station. The base station can determine the position of the mobile station and communicate the position back to the mobile station. By offloading much of the processing to the base station, energy consumption of the mobile station is reduced.

    Abstract: Methods, systems, and computer programs are presented for cloud-offloaded position calculation with on-device acquisition. One method includes operations for collecting raw global positioning system (GPS) signals for a set of positions, and storing in memory the raw GPS signals. The method further includes processing the raw GPS signals in batch mode at the computing device to obtain acquisition data for the positions, where the processing includes identifying tasks for parallel processing by a graphics processing unit (GPU), performing, by the GPU, the tasks in parallel by assigning each of the tasks to a core processor within the GPU, and combining results from performing the tasks to obtain the acquisition data. Additionally, the method includes an operation for transmitting the acquisition data to a server for calculating locations for the set positions at the server, the server storing the locations and making the locations available for location-tracking applications.

    Abstract: Apparatuses, systems, and methods for mitigating the effects of null zones on the measurements of Global Navigation Satellite System (GNSS) receivers are described. In one aspect, a GNSS receiver calculates both a filtered value of an integrated and summed value for a punctual correlator of a satellite signal (“the calculated filtered punctual correlator value”) and an average of integrated and summed correlator values for a plurality of noise/offset correlators of the satellite signal (“the calculated average noise/offset correlator value”). The GNSS receiver then calculates a signal energy loss parameter ESL of the satellite signal using the calculated filtered punctual correlator value and the calculated average noise/offset correlator value and processes the satellite signal measurement based at least on the signal energy loss parameter ESL and a predetermined threshold ThSL presently corresponding to the punctual and noise/offset correlators of the satellite signal.
