摘要： Methods and apparatus provide for positioning of a rover antenna from GNSS data derived from multi-frequency signals and correction data derived from a network of reference stations. Rover antenna position and multi-frequency ambiguities are estimated at each epoch. An ionospheric filter models variation in ionospheric bias per satellite. A set of ionospheric carrier-phase ambiguities is estimated at least when the multi-frequency ambiguities have attained a predetermined precision. The estimated ionospheric carrier-phase ambiguities are cached. After detecting interruption of signal at the rover antenna and determining reacquisition of signals at the rover antenna, an ionospheric bias per satellite over an interruption interval is predicted. For each satellite, a cached ionospheric carrier-phase ambiguity is combined with a predicted ionospheric bias to obtain a post-interruption ionospheric ambiguity estimate. The post-interruption ionospheric ambiguity estimates are used to aid estimation of rover antenna position after signal reacquisition.

摘要： A navigation receiver operating in a differential navigation mode transmits primary estimates of coordinates with an accuracy estimate that can vary during operation. To improve the positioning quality when the accuracy estimate changes, smoothed estimates of coordinates are generated according to a two-branch algorithm. The current-epoch accuracy estimate is compared to a current-epoch value of threshold accuracy. Upon determining that the current-epoch accuracy estimate is greater than or equal to the current-epoch value of threshold accuracy, the current-epoch smoothed estimates of coordinates are set equal to the current-epoch extended estimates of coordinates calculated from the sum of the previous smoothed estimates of coordinates and coordinate increments calculated from carrier phases. Upon determining that the current-epoch accuracy estimate is less than the current-epoch value of threshold accuracy, the current-epoch smoothed estimates of coordinates are generated based on the sum of the current-epoch extended estimates of coordinates and a correction signal.

摘要： In order to enable a geopositioning receiver of a user to resolve phase ambiguities without necessarily using multi-frequency observations, assistance data is developed thanks to measurements made at a reference network (10, 12, 14) and sent to the receiver of the user. The assistance data used preferably consist of transmitter clock values associated with the carrier code sliding combination (Θeme) or with data sufficient for reconstructing said values. The transmitter clock values associated with the carrier code sliding combination (Θeme) can be reconstructed from iono-free transmitter clock values (heme) and clock biases (C′eme), for example.

摘要： Methods and apparatus are presented for determining a position of a GNSS rover antenna from observations collected at the antenna over multiple epochs from satellite signals of multiple GNSS, wherein the observation data of each GNSS has a distinct data format. The observation data of each GNSS are presented in a generic GNSS data format, which differs from the distinct data format of the GNSS, to obtain a set of generic data. A set of difference data is prepared representing differences between the converted observation data and the generic data. When at least four satellites are tracked, the generic data of the tracked satellites of multiple GNSS are used to compute a standalone antenna position. When at least five satellites are tracked, the generic data of the tracked satellites of multiple GNSS are used to compute a real-time kinematic antenna position.

摘要： A scintillation caused by ionospheric irregularities during Global Navigation Satellite System (GNSS) measurements is detected. A first input GNSS measurement corresponding to a navigation satellite and corresponding to a first carrier frequency and a second GNSS measurement corresponding to the navigation satellite and corresponding to a second carrier frequency, in which the second carrier frequency is different from the first carrier frequency, are received. A geometry-free combination (GFC) parameter based at least in part on the first input GNSS measurement, the second input GNSS measurement, the first carrier frequency, and the second carrier frequency is calculated. The occurrence of a scintillation caused by an ionospheric irregularity is determined based at least in part on the GFC parameter. In an embodiment of the invention, the dispersion of the GFC parameter over a specified time interval is determined. A scintillation is detected if the dispersion exceeds a specified threshold value.

摘要： A signal processing method of a positioning apparatus includes the following steps. A satellite signal is received to provide at least a distance information. A correction value of a phase measurement time is generated according to the distance information and phase data of the satellite signal are corrected in sequence accordingly. The phase data are received and when a quantity of the phase data is equal to a preset quantity, a first low order polynomial fitting and a first Chi-square test are performed to generate an estimated parameter. A next phase data of the satellite signal is estimated to generate an estimated phase data according to the estimation parameter. An actual phase data is obtained. A detection and a compensation of a cycle slip are performed according the estimated phase data and the actual phase data to output a corrected phase observation value.
