摘要： It is proposed a determination device, a method for determining navigation information and a navigation device comprising: a receiving circuit configured to receive a first signal from a first navigation satellite, the first signal comprising a first timestamp; a determination circuit configured to determine a velocity of the first navigation satellite at the first timestamp in a second coordinate system based on ephemeris data of the first navigation satellite, the second coordinate system being tilted in relation to the equatorial plane; the determination circuit further configured to determine a velocity of the first navigation satellite in a first coordinate system that is earth fixed and rotating with earth, by applying a transformation matrix to the determined velocity of the first navigation satellite in the second coordinate system and adding a correction term based on a time derivative of the transformation matrix; a navigation circuit configured to determine navigation information of the receiving circuit within the first coordinate system based on at least the determined velocity of at least the first navigation satellite.

摘要： The system can include a hardware processor in communication with the computer-readable storage. The instructions, when executed by the hardware processor, are configured to cause the system to receive a plurality of photographs of space objects within a time domain. Each of the plurality of photographs can correspond to a latitude domain, a longitude domain, and a timestamp within the time domain. The system can also receive image data derived from the plurality of photographs. The system can also receive a user selection of a latitude range within the latitude domain, a longitude range within the longitude domain, and a time range within the time domain.

摘要： Some embodiments of the invention relate to generating correction information based on global or regional navigation satellite system (NSS) multiple-frequency signals observed at a network of reference stations, broadcasting the correction information, receiving the correction information at one or more monitoring stations, estimating ambiguities in the carrier phase of the NSS signals observed at the monitoring station(s) using the correction information received thereat, generating residuals, generating post-broadcast integrity information based thereon, and broadcasting the post-broadcast integrity information. Other embodiments relate to receiving and processing correction information and post-broadcast integrity information at NSS receivers or at devices which may have no NSS receiver, as well as to systems, NSS receivers, devices which may have no NSS receiver, processing centers, and computer programs. Some embodiments may for example be used for safety-critical applications such as highly-automated driving and autonomous driving.

摘要： A method for reduced-outlier satellite positioning includes receiving a set of satellite positioning observations at a receiver; generating a first receiver position estimate; generating a set of posterior observation residual values from the set of satellite positioning observations and the first receiver position estimate; based on the set of posterior observation residual values, identifying a subset of the satellite positioning observations as statistical outliers; and after mitigating an effect of the statistical outliers, generating a second receiver position estimate having higher accuracy than the first receiver position estimate.

摘要： A mechanism converts positioning correction information included in an SSR message as defined by “RTCM STANDARD 10403.2” to positioning correction information conforming to “RTCM 10402.3”. A conversion device includes a computation processing section that acquires a plurality of types of positioning correction information conforming to “RTCM STANDARD 10403.2”, an approximate position being a positioning result, and a satellite position of a satellite that transmits positioning information based on which the approximate position is calculated, and based on the types of positioning correction information, the approximate position, and the satellite position that have been acquired, generates pieces of element data, such as CLR and ORB, which are elements used for generating the types of positioning correction information conforming to “RTCM 10402.3”, by computation, and a conversion calculation section that generates the types of positioning correction information conforming to “RTCM 10402.3”, based on the pieces of element data.

摘要： A method is provided whereby a group of receivers local to one another make GNSS measurements of a number of satellites, from one or multiple different GNSS's, and by combining the measurements of the same satellites made by the different receivers it is possible given sufficient conditions to determine the positions of the receivers and the satellite errors such that the positions obtained are equivalent to those obtained from a traditional differential GNSS system, without the need for a static reference receiver at a known location.

摘要： A parking lot entrance recognition method comprises the steps: reading GPS data of all vehicles appearing in a specified region within a specified time one-by-one; acquiring discontinuity points after it is confirmed that vehicle position information is lost; and comparing the discontinuity frequency of each discontinuity point with a frequency threshold to determine whether or not the discontinuity point is an entrance of an underground parking lot. In this way, the entrances of parking lots can be rapidly positioned, so that drivers can park conveniently and can also drive purposefully; and meanwhile, based on the analysis of the GPS data, the positioning accuracy is higher.
