Abstract: A mobile system, such as a wireless phone, communicates its location or other position information, such as pseudoranges, to a server system and optionally sends permission criteria defining which other mobile systems are allowed to access its location. In the case where the mobile system does not provide its location, the server determines the location using the other position information provided e.g. pseudoranges for satellites in view of the mobile system. The server system sends the location to other mobile systems in accordance with the permission criteria, with or without a request from another mobile system for the location. If no permission criteria has been sent by the mobile system, the server system queries the mobile system for the permission criteria in response to a request for the location. If no permission criteria is sent by the mobile system, or if the permission criteria sent denies the request, the server system can, alternately, not reply to the request or reply with an error message. The permission criteria can include additional access limitations such as dates or times during which access is permitted or denied, and geographic areas in which access is permitted or denied.
Abstract translation: 诸如无线电话之类的移动系统将其位置或其他位置信息（诸如伪距）传送给服务器系统，并且可选地发送允许其他移动系统被允许访问其位置的许可标准。 在移动系统不提供其位置的情况下，服务器使用例如提供的其他位置信息来确定位置。 鉴于移动系统的卫星伪距。 服务器系统根据许可标准将位置发送到其他移动系统，有或者没有来自另一个移动系统的关于该位置的请求。 如果移动系统未发送许可标准，则服务器系统响应于对该位置的请求而向移动系统查询许可标准。 如果移动系统没有发送许可标准，或者发送的许可标准拒绝了请求，服务器系统可以交替地不回复请求或回复错误消息。 许可标准可以包括额外的访问限制，例如允许或拒绝访问的日期或时间以及访问被允许或拒绝的地理区域。

Abstract: "sistema de calibragem e correção para sistemas de localização de posição por satélite". para fornecer medições de posição precisas e rápidas em um sistema de localização de posição móvel prático, o receptor gps é calibrado, um erro de freqüência no próximo período de tempo é previsto utilizando-se uma primeira freqüência travada em um sinal transmitido externamente, e uma segunda freqüência é gerada por um oscilador gps. para se prever o erro no próximo período de tempo, várias medições são realizadas através do tempo, estimativas de erro são realizadas, uma função erro é aproximada em resposta ao conjunto de estimativas de erro. esse erro previsto é então utilizado para corrigir o receptor gps no próximo período de tempo. em uma implementação, um dispositivo portátil de múltiplas funções é descrito para fornecer a comunicação celular utilizando uma rede de estações celulares que operam em freqüências celulares ideais predefinidas, e também para fornecer a localização de posição utilizando satélites gps que transmitem sinais gps em uma freqüência gps predefinida.

Abstract: A method for operating a location apparatus (25-27) in a satellite positioning system (10) in a client/server architecture and a location apparatus (25-27) for use in the satellite positioning system. An example of the operations of the method and location apparatus include determining and storing one or more sets of pseudorange correction parameters, each having a corresponding correction parameter time stamp, receiving one or more transmissions from one or more mobile units (12), in which the transmissions include one or more sets of pseudoranges, each having a corresponding pseudorange time stamp, and selecting, based on the correction parameter time stamps and the pseudorange time stamps, at least one of the sets of correction parameters for correcting at least one of the sets of pseudoranges.

Abstract: To provide accurate and quick position measurements in a practical mobile position location system, the GPS receiver is calibrated, a frequency error in the next time period is predicted using a first frequency locked to an externally transmitted signal, and a second frequency is generated by a GPS oscillator. To predict the error in the next time period, several measurements are made over time, error estimations are made, an error function is approximated responsive to the set of error estimations. This predicted error is then used to correct the GPS receiver in the next time period. In one implementation, a multiple function portable device is disclosed for providing cellular communication using a network of cellular stations that operate at predefined ideal cellular frequencies, and also for providing position location using GPS satellites that transmit GPS signals at a predefined GPS frequency.

Abstract: Position location signaling system, apparatus, and method are disclosed. Position location beacons can each be configured to transmit a frequency interlaced subset of orthogonal frequencies spanning substantially an entire channel bandwidth. The orthogonal frequencies can be pseudorandomly or uniformly spaced, and each beacon can be allocated an equal number of orthogonal frequencies. Each frequency of the interlaced subset of orthogonal frequencies can be modulated with an element of a predetermined data sequence. A mobile device can receive one or more of the beacon signals and determine a position using a position location algorithm that determines position in part on an arrival time of the beacon signal. Where the mobile device can receive three or more beacon signals, the mobile device can perform position location by trilateration to the beacon positions based, for example, on a time difference of arrival.

Abstract: Methods and apparatuses for frequency synchronizing basestations in a cellular communication system. In one aspect of the invention, a method to predict a timing of transmission of a basestation in a cellular communication system includes: receiving a first time tag for a first timing marker in a first cellular signal transmitted from the basestation; receiving a second time tag of a second timing marker in a second cellular signal transmitted from the basestation; and computing a frequency related to the basestation using the first and second time tags. Each of the time tags are determined using at least one satellite positioning system signal received at a mobile station which receives the corresponding time marker.

Abstract: Methods and apparatuses for determining a position of a mobile satellite positioning system (SPS) receiver which is coupled to a communication receiver or transceiver. In one exemplary method, a change in a communication signal received by the communication receiver is determined. A parameter, based on the change, is determined, and SPS signals from SPS satellites are processed according to the parameter. According to further details of this method, the change involves the fluctuation of the level of the communication signal and the parameter is a motion information which specifies a frequency range for searching for SPS signals in the process of acquiring the SPS signals from SPS satellites. In an alternative embodiment the change in the communication signal is a change in the transmitted signal in response to power control commands. Apparatuses, such as a mobile communication system which includes an SPS receiver and a communication receiver, are also described.
