摘要： The present disclosure provides an electronic control device capable of suppressing variations in the position of a work machine calculated based on satellite signals received by a GNSS terminal due to changes in the GNSS communication environment, and eliminating the position error after improvement of the communication environment in a shorter time than before. The electronic control device includes: a positioning quality determination section 211 that determines whether the positioning quality is good or poor based on GNSS information; a traveling state determination section 212 that determines the traveling state, including a stop state, based on the velocity of the work machine; and a smoothing section 213 that performs smoothing processing to the GNSS information. The smoothing section 213 changes the processing intensity to weak if the smoothing condition is not satisfied, the condition being that the positioning quality is good and the traveling state is stop, and changes the processing intensity to strong after a time equivalent to update cycle since the smoothing condition has been satisfied.

摘要： Methods and apparatus to monitor GPS/GNSS atomic clocks are disclosed. An example method includes establishing a measured difference between an atomic frequency standard (AFS) and a monitoring device. The method also includes modeling an estimated difference model between the AFS and the monitoring device, and computing a residual signal based on the measured difference and the estimated difference model. In addition, the method includes analyzing, by a first detector, the residual signal at multiple thresholds, each of the thresholds having a corresponding persistency defining the number of times a threshold is exceeded before one or more of a phase jump, a rate jump, or an acceleration error is indicated. Furthermore, the method includes analyzing, by a second detector, a parameter of the estimated difference model at multiple thresholds, each of the thresholds having a corresponding persistency defining the number of times a drift threshold is exceeded before a drift is indicated.

摘要： A demodulation unit (13) corresponding to a GNSS signal processing device includes an operator (33). The operator (33) uses a first error detecting method when one of a first selection criterion in which an early late differential value ”CV EL is higher than a first threshold C1 (positive value) and an early differential value ”CV E is lower than a third threshold C3 (negative value), and a second selection criterion in which the early late differential value ”CV EL is lower than a second threshold C2 (negative value) and a late differential value ”CV L is lower than a fourth threshold C4 (negative value) is satisfied, and the operator (33) 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 highly accurate positioning operation is achieved regardless of an existence of multipath. An observed pseudorange ρ m (k) is acquired based on reception signals of positional signals (S101). A current determination estimated pseudorange ρ mp (k) is calculated based on a previous estimation result (S102). A determination difference value Delta ρm (k) is calculated based on the observed pseudorange ρ m (k) and the estimated pseudorange ρ m p(k) (S103). A determination threshold σ Deltaρ is calculated based on a C/No of the reception signal and PDOP (S104). If the determination difference value Delta ρm (k) is below the threshold σ Deltaρ , an error variance σ m (k) is calculated using an approximate equation of the C/No (S105(NO) → S106), and if the determination difference value Delta ρm (k) is above the threshold σ Deltaρ , the error variance σ ρm (k) is calculated based on the threshold σ Deltaρ (S105(YES) → S107).
