    • Each of a first and a second navigation satellite system (NSS) are adapted to operate according to a first and a second specification, respectively, and each includes a first and a second plurality of space vehicles (SV), respectively. Each of the first and the second plurality of SVs are adapted to be identified by a first and a second plurality of unique corresponding identifications (IDs), respectively. A processor is adapted to receive and identify a first plurality of corresponding signals transmitted from the first plurality of SVs in response to the first plurality of unique corresponding IDs. The processor is adapted to receive and identify a second plurality of corresponding signals transmitted from the second plurality of SVs in response to the second plurality of unique corresponding IDs. The processor is adapted to determine position location information in response to receiving and identifying the first plurality of corresponding signals and the second plurality of corresponding signals.

    • The propagation time for propagation of a radio signal from a radio transmitting station to a radio receiving station is estimated based on calculated correlation values, calculated energy values and a known energy value. The receiving station receives a series of received signals that respectively correspond to radio signaling bursts transmitted by the radio transmitting station. Each of the radio signaling bursts includes a known signaling sequence. The calculated correlation values are indicative of correlations between the received signals and the known sequence, the calculated energy values are calculated for the respective received signals, and the known energy value is the energy of the known sequence.
    • 基于计算的相关值,计算出的能量值和已知的能量值来估计从无线电发射站到无线电接收站的无线电信号的传播的传播时间。 接收站接收分别对应于由无线电发射台发射的无线电信令突发的一系列接收信号。 无线电信令突发中的每一个包括已知的信令序列。 所计算的相关值表示接收信号和已知序列之间的相关性,针对各个接收信号计算出计算出的能量值,已知能量值是已知序列的能量。

    • In a mobile telecommunications network, a mobile station (MS) is configured to generate and uplink transmit position measuring data prior to and/or during a call connection, without noticeably interrupting the user or degrading the quality of service provided. Position measuring data can be uplink transmitted over an idle traffic channel during a call set up operation for a brief moment while the call connection is being completed. Position measuring data can also be uplink transmitted during a call by selectively stealing data positions or burst positions in the uplink signal. The position measuring data is received by a plurality of base stations and uplink signal characteristics are measured and collected. The measured uplink signal characteristic data from several base stations is then used to determine a current approximate geographical location of the mobile station.
    • 在移动电信网络中,移动台(MS)被配置为在呼叫连接之前和/或期间生成和上行发送位置测量数据,而不会明显地中断用户或降低提供的服务质量。 当呼叫连接正在完成时,位置测量数据可以在呼叫建立操作期间通过空闲业务信道被上行链路传输。 位置测量数据也可以在呼叫期间通过选择性地窃取上行链路信号中的数据位置或突发位置来上传。 位置测量数据被多个基站接收,并且测量和收集上行链路信号特性。 然后使用来自几个基站的所测量的上行链路信号特征数据来确定移动台的当前大致地理位置。

    • Positions of non-reference wireless transceivers to be added to a wireless communication network are determined as follows. Each non-reference wireless transceiver performs measurements of times of arrival (TOA) of signals transmitted by other non-reference wireless transceivers, as well as reference wireless transceivers. Thereafter, time difference of arrival (TDOA) values are computed from at least two types of pairs of measurements as follows: (a) unknown-unknown TDOA values are obtained as differences between TOA measurements of signals transmitted by non-reference wireless transceivers and (b) unknown-known TDOA values are obtained as differences between a TOA measurement of a signal transmitted by a non-reference wireless transceiver and another TOA measurement of another signal transmitted by a reference wireless transceiver. Both types of TDOA values are used to solve simultaneous equations to identify the positions of the non-reference wireless transceivers and optionally times of transmission of the signals by the non-reference wireless transceivers.
    • 要添加到无线通信网络的非参考无线收发器的位置确定如下。 每个非参考无线收发器执行由其他非参考无线收发器以及参考无线收发器发送的信号的到达时间(TOA)的测量。 此后,从至少两种类型的测量对计算出到达时间差(TDOA)值如下:(a)未知未知的TDOA值作为由非参考无线收发器发送的信号的TOA测量值之差和( b)未知的TDOA值作为由非参考无线收发器发送的信号的TOA测量与由参考无线收发器发送的另一信号的另一TOA测量之间的差异获得。 两种类型的TDOA值用于求解联立方程以识别非参考无线收发器的位置,以及非参考无线收发器可选择地传输信号的时间。
