摘要： The present disclosure relates to the technical field of communication, and provides a validity period determining method and apparatus, a device, and a storage medium. The method includes: determining, by a terminal, a validity period of ephemeris information, the validity period meeting a synchronization requirement of the terminal. By determining the validity period of the ephemeris information that meets the synchronization requirement, the terminal can ensure the real-time accuracy of the ephemeris information at the terminal, thereby ensuring that a time delay and a Doppler frequency shift calculated by the terminal based on the ephemeris information have only small errors. Since the errors do not exceed a range tolerated by the synchronization requirement, the synchronization performance of the terminal can be guaranteed.

摘要： An apparatus computes first locations of a satellite for several points in time based on a first set of parameters values broadcast by the satellite for a first validity period and second locations of the satellite for these points in time based on a second set of parameter values with associated second validity period. The first or second validity period is extended by an equation of motion, which includes forces acting on the satellite. The apparatus computes a value of an error component for points in time by comparing first with second locations and fits parameter values of a model to the values of the error component to obtain a model of a time-evolution of values of the error component. The apparatus provides the model of the time-evolution as a basis for a correction of locations of the satellite that are computed based on the first set of parameter values.

摘要： A method and system for a mobile station to determine its position (or velocity) and time using a hybrid combination of satellite orbit data. In one aspect, the mobile station combines predicted orbit data from one satellite and real-time orbit data from another satellite in the determination of a fix. The combination can be made to the satellites in the same or different satellite systems. The mobile station can use the real-time orbit data of a satellite at one time period and the predicted orbit data of the same satellite at another time period. In another aspect, the mobile station can use the real-time orbit data to correct the clock bias in the predicted orbit data. The correction to the clock bias can be made to the same satellite that provides the real-time orbit data, or to a different satellite in the same or in another satellite system.

摘要： An apparatus, method, and system for predicting subframes of GPS signals. The apparatus includes a processor capable of determining whether a subframe is an almanac subframe, setting a timehead and adding it to a TOW, setting a TLM message based on a value of the TOW, generating a CRC for a predicted subframe, and a memory for storing the predicted subframe. The memory may vary in size based on the number of predicted subframes. The processor is further capable of determining whether the value of the TOW is less than the number of seconds in a week, calculating a position of the predicted subframe in the memory, and setting a valid flag.
