    摘要： Embodiments of the invention can resolve conflicts between candidate master network devices such as may be encountered in a failover condition. In a common type of failover protocol, two or more candidate master devices send messages to each other prior to a failover condition. A witness device (or process or service) also casts a vote to prevent a stalemate condition between the two candidate master devices that could lead to an error condition where multiple masters, or no masters, are elected.

    摘要： Computer-implemented methods and apparatus are presented for processing data collected by at least two receivers from multiple satellites of multiple GNSS, where at least one GNSS is FDMA. Data sets are obtained which comprise a first data set from a first receiver and a second data set from a second receiver. The first data set comprises a first FDMA data set and the second data set comprises a second FDMA data set. At least one of a code bias and a phase bias may exist between the first FDMA data set and the second FDMA data set. At least one receiver-type bias is determined, to be applied when the data sets are obtained from receivers of different types. The data sets are processed, based on the at least one receiver-type bias, to estimate carrier floating-point ambiguities. Carrier integer ambiguities are determined from the floating-point ambiguities. The scheme enables GLONASS carrier phase ambiguities to be resolved and used in a combined FDMA/CDMA (e.g., GLONASS/GPS) centimeter-level solution. It is applicable to real-time kinematic (RTK) positioning, high-precision post-processing of positions and network RTK positioning.

    摘要： Computer-implemented methods and apparatus are presented for processing data collected by at least two receivers from multiple satellites of multiple Global Navigation Satellite Systems (GNSS), where at least one GNSS is Frequency Division Multiple Access (FDMA). Data sets are obtained which comprise a first data set from a first receiver and a second data set from a second receiver. The first data set comprises a first FDMA data set and the second data set comprises a second FDMA data set. At least one of a code bias and a phase bias may exist between the first FDMA data set and the second FDMA data set. At least one receiver-type bias is determined, to be applied when the data sets are obtained from receivers of different types. The data sets are processed, based on the at least one receiver-type bias, to estimate carrier floating-point ambiguities. Carrier integer ambiguities are determined from the floating-point ambiguities. The scheme enables Globalnaya Navigatsionnaya Sputnikovaya Sistema (GLONASS) carrier phase ambiguities to be resolved and used in a combined FDMA/Code Division Multiple Access (CDMA)(e.g., GLONASS/Global Positioning System (GPS) centimeter-level solution. It is applicable to real-time kinematic (RTK) positioning, high-precision post-processing of positions and network RTK positioning.

    摘要： In one embodiment, a first network node in a subnet retrieves a network configuration from a second network node located outside the subnet. The first network node communicates with at least one other network node to collect information from inter-node communication packets containing network address information other than an address assignment to the first network node. The first network node determines an available network address based on the network address information contained in the collected inter-node communication packets. The first network node is assigned the available network address and locates a network address for at least one subnet router. The network node accesses the second network node located outside the subnet, using the located network address for the at least one subnet router, for an available network configuration from a list of network configurations. The first network node is assigned the available network configuration.
