摘要： Method and apparatus for managing a network element in a satellite navigation data distribution system is described. In one example, a network element includes a processor for processing satellite navigation data. For example, a network element may be a reference station, a hub, or a server in the satellite navigation data distribution system. The network element includes a memory for maintaining status variables associated with the processing of the satellite navigation data. The status variables may relate to the integrity of the satellite navigation data. The network element further includes a management agent for monitoring states of the status variables and communicating with a network management system to exchange information related to the states of the status variables. In one example, the management agent is configured to communicate using a simple network management protocol (SNMP).

摘要： Method and apparatus for time management in a position location system is described. In one example, a time relation is received at a server. The time relation includes a relationship between an air-interface time of a base station and a satellite time for a satellite constellation from a first satellite positioning system (SPS) receiver. The time relation is then stored in the server. In another example, satellite time is determined at a first time for a satellite constellation at an SPS receiver. A time offset is determined between the satellite time and an air-interface time of a base station. The time offset is stored within the SPS receiver. A position of the SPS receiver is computed at a second time using satellite measurements and the stored time offset.

摘要： A method and apparatus for mitigating interference in a satellite signal receiver is described. The satellite signal receiver receives satellite signals from a plurality of satellites. In one example, data transmission of a wireless transceiver operating in proximity to the satellite signal receiver is monitored. A control signal is transmitted to the satellite signal receiver upon occurrence of data transmission from the wireless transceiver. Signal integration within the satellite signal receiver is then gated is response to the control signal. In another example, one or more values of satellite signal samples are selected from a plurality of possible values. A percentage of satellite signal samples having the one or more selected values is monitored over a predefined period. Signal integration within the satellite signal receiver is gated in response to the percentage exceeding a predefined threshold. In yet another example, a gain setting of an automatic gain control circuit within the satellite signal receiver is adjusted in response to detection of interference.
