摘要

Method for determining a location of an object, having a receiver of satellite navigation (GNSS), the method comprising the steps of; - reception of signals by the GNSS receiver are by GNSS transmitters (GNSSE1 to GNSSEn) located on board satellites (SAT1 to SATN) which are located in the visual field of the object transmitted; - updating the service data in the object data service being provided by a GNSS service provider and include satellite clock data indicating internal clocks of the satellites (SAT1, a sateen); Data from the satellite orbit indicating the locations of the satellites (SAT1 to Satn); deviation data code delay method relating to deviations code delay of GNSS transmitters (GNSSE1 to GNSSEn); and ionospheric model data indicating a state of an ionosphere; - determination on the basis of data from ionospheric model data indicating ionospheric delay corrections for the delays of the signals, resulting delays signals of a passage of signals through the ionosphere between transmission of signals from GNSS transmitters (GNSSE1 to GNSSEn) and reception of signals by the GNSS receiver (SURGNSS); - obtaining observation data code signals being observational data code concerning the data transmitted with the signals and comprising observable code relating to data transmitted with the signals; - obtaining observation data carrier phase signal, and the data observation carrier phase relative to the phases of the carrier signals and comprising observables of the carrier phase relative to the phase carrier signals; and - determining a target signal based on data satellite clock data from the satellites orbit, the offset data of the delay of the satellite data ionospheric delay certain of the code observation data code obtained from signals and data observation carrier phase obtained from the signal in which all observable code and all observable phase of the carrier involved in step determination target signal is processed in an undifferentiated manner, wherein in the step of determining the location of the object are processed at least one linear combination of observables that is without ionosphere, and further a linear combination of observables which is not ionosphere.
