摘要： Determination of a signal loss profile relative to a receiver based on measured signal power of a sounding signal from a sounding transmitter having a known signal power in free space relative to the receiver. The signal loss profile may include a plurality of signal loss values corresponding to a plurality of received sounding signals at the receiver. In an embodiment, the sounding signal may comprise a GNSS navigational signal (e.g., a GPS signal). The signal loss profile may be used to extrapolate signal loss for a transmitter collocated with the receiver. In turn, the signal loss profile may be used in conjunction with a shared spectrum system to model a signal propagation from the collocated transmitter when determining allocation of a shared spectrum resource of the shared spectrum system.

摘要： Location of a device within a monitored environment with compromised communication with ranging communication nodes. Specifically, an intermediate device previously located by communication with ranging communication nodes is provided to provide a ranging signal to a device to be located. The device to be located may in turn use a ranging signal received from communication with the previously located device and one or more ranging communication nodes to resolve a location.

摘要： A GNSS cooperative receiver system that can be utilized when one or more GNSS receivers is in a compromised position where it cannot receive direct signals from a sufficient number of GNSS satellites. This may in the interior of an office building or multi-dwelling unit, which may be in the vicinity of other tall buildings. The receivers determine their relative positions from one of various ranging techniques, and then with this relative position information, pseudoranges, and correlation values from the various GNSS receivers, the best GNSS solution can be determined for the group of cooperative receivers. This could include two or more receivers in a group. There also related techniques for one receiver to be a designated, remote anchor for other GNSS receivers that need such assistance.

摘要： Wave based signals such as radio transmissions are susceptible to frequency alterations caused by the relative movement between a transmitter and a receiver. In a satellite context, the radio signals emitted by a satellite based transmitter may take on a frequency higher or lower than the actual frequency at which they are generated depending on whether the satellite is moving toward or away from the receiver, respectively. By calculating the theoretical frequency shift (Doppler shift) that should occur if a signal travels directly from a satellite to a receiver, the actual frequency of the signal as received can be used to determine if the signal's integrity is sufficient or if it has been compromised by some sort of interference or malfunction.

摘要： An approach to joint processing of GNSS signals to determine a receiver location and common mode bias associated with grouped records corresponding to GNSS signals. In this regard, a receiver may acquire signals from a GNSS space vehicle over a relatively long period of time. In turn, records corresponding to received signals may be stored and grouped. The grouping of records may be based on assumptions of a common-mode bias for certain records (e.g., records acquired within a given duration of an observation time period). Upon acquisition of a suitable number of records, an over-determined system may be established that is used in iterative processing to solve for location and/or bias values associated with the respective common-mode bias for each group of records. As such, improved receiver performance may be realized.
摘要翻译：联合处理GNSS信号以确定与对应于GNSS信号的分组记录相关联的接收器位置和共模偏置的方法。在这方面，接收机可以在相对长的时间段内从GNSS空间车辆获取信号。反过来，可以存储和分组对应于接收到的信号的记录。记录分组可以基于对于某些记录（例如，在观察时间段的给定持续时间内获得的记录）的共模偏差的假设。在获得合适数量的记录之后，可以建立用于迭代处理的过度确定的系统，以解决与每组记录相应的相应共模偏置相关联的位置和/或偏置值。因此，可以实现改进的接收机性能。
