摘要： The disclosure herein relates to a receiver for use in a user satellite, located among other things partly or wholly on orbits remote from Earth, for example. The receiver comprises a receiving unit and a processing unit. The receiving unit is configured to receive signals transmitted by navigation satellites of one or more global navigation satellite systems (GNSS). The processing unit is configured to determine measurements based on the data contained in the signals received. The processing unit is further configured to carry out a calculation of position, velocity and time (PVT) based on batch processing of the measurements. The disclosure herein further relates to a method and a user satellite.

摘要： A demodulation unit for a GNSS signal processing device includes an operator that uses a first error detecting method when one of a first selection criterion in which an early late differential value is higher than a first threshold (positive value) and an early differential value is lower than a third threshold (negative value), and a second selection criterion in which the early late differential value is lower than a second threshold (negative value) and a late differential value is lower than a fourth threshold (negative value) is satisfied, and the operator uses a second error detecting method when neither criterion is satisfied. A code phase range where an error detection value is not 0 is wide with the first error detecting method, and the code phase range where the error detection value is not 0 is narrow with the second error detecting method.

摘要： A process bus-applied protection system includes a process bus, a plurality of MUs (merging units), and a plurality of IEDs (intelligent electric devices). Each of the MUs is configured to sample a current and a voltage of a power system at timing synchronized with a time synchronization signal received through the process bus. Each of the IEDs is configured to be capable of outputting the time synchronization signal to the process bus by serving as a transmission source, and receiving, through the process bus, the time synchronization signal from another IED. The plurality of IEDs have a predetermined priority. Each of the IEDs is configured, when the IED does not receive the time synchronization signal from an IED having a higher priority than that of the IED and serving as a transmission source, to output the time synchronization signal to the process bus by serving as a transmission source.

摘要： Methods and apparatuses are provided for a portable device to minimize power consumption of its measurement engine while maintaining a desired level of accuracy. One such method forms a control loop, in which a value of a metric indicating a difference between the current estimated accuracy and the desired level of accuracy is calculated and then filtered to produce one or more filtered values. Using the one or more filtered values and current values of one or more modifiable measurement parameters, new values for the one or more modifiable measurement parameters are generated and then used to take the next measurement.

摘要： In a receive system, a plurality of correlators correlate a received signal with a plurality of delayed versions of a reference signal to generate a plurality of correlator outputs. A timing error detector estimates an optimal timing based on a set of correlator outputs, and determines a timing error based on (i) the estimated optimal correlation point and (ii) an existing timing, such that the timing error is hard or soft limited between two positive thresholds and two negative thresholds.
