摘要： The present invention provides a method and an associated time manager for managing a time relation between system times of different remote systems, including: at a first moment, obtaining a first value of a first system time and accessing a periodically updating reference counter to obtain a first count; at a second moment, updating the time relation by: obtaining a second value of a second system time along with a second count, and calculating a second value of the first system time by summing the first value of the first system time and an extrapolation interval calculated according to a difference between the first count and the second count. Thus, when synchronization with a first remote system ends, a fourth value of the first system time may be calculated according to a fourth value of the second system time and a previously stored time relation.

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： Methods and systems for repurposing of a global navigation satellite system receiver for receiving low-earth orbit (LEO) communication satellite timing signals may comprise receiving a medium Earth orbit (MEO) satellite signal and/or a LEO signal in a receiver of the communication device. The MEO or LEO signal may be down-converted, and a position of the communication device may be calculated utilizing the down-converted signal. The signal may be down-converted utilizing a local oscillator signal generated by a phase locked loop (PLL), which may be delta-sigma modulated via a fractional-N divider. A clock signal may be communicated to the PLL utilizing a temperature-compensated crystal oscillator. The signal may be down-converted to an intermediate frequency or down-converted directly to baseband frequencies. The signal may be processed utilizing surface acoustic wave (SAW) filters. In-phase and quadrature signals may be processed in the RF path utilizing a two-stage polyphase filter.

摘要： Methods, systems, and devices for monitoring a Real Time Clock (RTC) oscillator using Digital Signal Processing (DSP), where a resistance/capacitance (RC) oscillator is configured to output a digital pulse signal and a digital RTC Monitor Integrated Circuit (IC) is configured to monitor the RTC oscillator timing signal using the RC oscillator signal. In one aspect, the RTC Monitor IC includes an RTC input configured to receive the RTC oscillator timing signal; an RC input configured to receive the RC oscillator digital pulse signal; and an RTC reset output configured to output an RTC reset signal when a comparison of the RTC and RC oscillator inputs show the RTC oscillator has missed one or more clock cycles. A single wire input/output for both reset and interrupt signals between circuits is also described.

摘要： A terminal to be carried into a moving object includes a first information obtaining unit, a time stamp adding unit, a second information obtaining unit, and an integration unit. The first information obtaining unit obtains positional information of the terminal. The time stamp adding unit adds a timestamp to the positional information obtained by the first information obtaining unit. The second information obtaining unit obtains, from the moving object, the positional information of the moving object having a timestamp added in the same time unit as the timestamp added by the object time stamp adding unit. The integration unit integrates positional information having a timestamp for which no positional information has been obtained by the first information obtaining unit, selectively from the positional information obtained by the second information obtaining unit, with the positional information obtained by the second information obtaining unit.

Additionally, detecting the failure of a GNSS based precision time source based on a calculated location of a GNSS receiver is disclosed. Moreover, the system may be further configured to distribute a time derived from the precision time source as a precision time reference to time dependent devices.

摘要： An integrated surrogate positioning system and method is disclosed for converting a received positioning signal to a desired output based on existing infrastructure of a host receiver. The system and method comprises a signal processing system for receiving and downconverting to digital, radio frequency positioning signals from a variety of constellations. A radio frequency signal generator receives the positioning solution and determines output positioning signal parameters based on the requirements of the host receiver. The signal generator produces an output baseband positioning signal based on the received positioning solution and the output positioning signal parameters and transmits the positioning signal to the host receive through existing infrastructure.

摘要： A navigation system comprises a GNSS receiver that receives GNSS signals on multiple tracking channels, an INS that generates inertial data, and a processor. A micro jump detection and correction module comprises an oscillator micro jump detector that monitors estimates of C/N0 in all tracking channels, and detects a micro-jump event when there is an abrupt decrease of C/N0 in all tracking channels. An offsets module defines a plurality of carrier NCO command offsets to search over signal Dopplers in all available tracking channels after the micro jump event is detected, and sends the carrier NCO command offsets to the GNSS receiver to be added to nominal carrier NCO commands. The micro jump detector selects a tracking channel with the highest C/N0 after carrier NCO command offsets are added to nominal carrier NCO commands, computes corrections for clock error estimates, and sends the corrections for the clock error estimates to a GNSS/inertial Kalman filter.
