  • Patent number: 9052161
    Abstract: Resolution of perspective in three dimensions is necessary for intermeshing real players into simulated environments during virtual training exercises. A combination of small sized sensors and image recognition tracking algorithms allows the tracking element to be placed directly on the device whose perspective is desired. This provides a solution to determining perspective as it provides a direct measurement from the center axis of the observer. This invention employs a perspective tracking device to determine a point-of-gaze or a point-of-aim in a three-dimensional space to a high degree of accuracy. Point-of-gaze may be used to determine views for head mounted displays and aim-points for weapons. The invention may operate in an unconstrained space allowing simulation participants to operate in a larger, open environment. Areas of interest in the environment are bounded by emitters which identify the region and its physical constraints.

A CPU included in the spacecraft generates a reference trajectory which is a trajectory for allowing the spacecraft in flight to arrive at the target position on a celestial body with the atmosphere, and which is identified based on velocity or energy of the spacecraft and on drag acceleration of the spacecraft. The CPU calculates a ratio between the range that is a distance from the current position based on the reference trajectory to the target position, and the real range that is a real distance from a current position to the target position, and corrects the reference trajectory by calculating the drag acceleration in the reference trajectory using the calculated ratio.

A UE may determine TOA for a cell based on multiple signals transmitted on different sets of subcarriers. The UE may perform correlation for a first signal (e.g., a synchronization signal) from the cell to obtain first correlation results for different time offsets. The UE may perform correlation for a second signal (e.g., a reference signal) from the cell to obtain second correlation results for different time offsets. The UE may combine the first and second correlation results and may determine the TOA for the cell based on the combined correlation results.

  • Patent number: 9024817
    Abstract: One embodiment is directed to an aircraft position report system. The system comprises a satellite, an aircraft position reporting receiver mounted on the satellite, an antenna element mounted on the satellite, and an antenna interface mounted on the satellite. The aircraft position reporting receiver receives aircraft position reports through the antenna element by associating a spot beam with a narrow coverage area. The aircraft position reports are derived from a signal produced by the antenna element. The antenna interface changes the narrow coverage area associated with the spot beam to receive aircraft position reports from a wide coverage region within a reporting period. In one exemplary embodiment, the antenna interface mechanically steers the spot beam for each receiver to one of the narrow coverage areas. In another exemplary embodiment, the antenna interface electronically steers the spot beam for each receiver to one of the narrow coverage areas.

  • Publication number: 20150097732
    Abstract: Tracking systems and methods for obtaining position coordinates of transmitters are provided. One or more transmitters send multiple carrier signals to multiple receivers, where the time difference of arrival of the multiple carrier signals are used to determine the location of each transmitter. Accuracy is obtained by using phase information of multiple carrier frequencies for time difference of arrival measurements. The accuracy obtained by a receiver depends on the quality of the received carrier signal; a received carrier signal may become distorted by the presence of multipath interference. By using multiple signals with different frequencies, the system can screen or compensate for multipath effects. This screening can be accomplished either through various signal-sampling techniques or by averaging the signals received at the receiver. Because signals with different frequencies have different multipath experiences, a computer can analyze and compensate for “good” and “bad” signals.

  • Publication number: 20150002337
    Abstract: Provided are architectures, systems, methods, and computer program products for real-time object locating and position determination using frequency channel diversity for transmitting and receiving position determination signals including bursts of location signals. Channelized frequency diversity of a short burst of small location signals that “hop” across multiple frequency channels is used to collectively produce a quasi-wideband position determination signal. Object tags operating with frequency channel diversity for transmitting location signals of position determination signals require low power consumption, but can still efficiently provide adequate position determination signals for reliable position determination.

  • Patent number: 8884820
    Abstract: Embodiments of a system and method for determining an angle-of-arrival (AOA) of signals received from a transmitting device are shown. Signals from the transmitting device are received through two or more pairs of spatially-diverse antennas. A non-inverted version of the signals received through a first antenna of a pair is injected into a first input of a surface-acoustic-wave (SAW) device. An inverted version of the signals received through a second antenna of the pair is injected into a second input of the SAW device. Signals present at tap outputs are processed to determine a time-difference-of-arrival (TDOA) between the signals received through each pair of antennas. The AOA may be calculated from the TDOAs determined from two or more pairs of antennas.

  • Patent number: 8855703
    Abstract: A method of driving a mobile communication terminal in a cellular network, includes monitoring with a control unit of the mobile communications terminal, reception power levels between the mobile communication terminal and cellular network base stations at a predefined monitoring rate for each base station. Timing information values for a number of base stations are intermittently monitored by the control unit. Drift of the timing information values for at least two of the base stations is monitored and significant motion of the mobile communication terminal is deemed detected if at least one of the timing information values indicates a drift equal to or exceeding a given timing drift threshold. The predefined reception power level monitoring rate is reduced to a reduced reception power level monitoring rate for at least a number of the base stations as long as the motion of the mobile communication terminal is not significant.
