原始语种摘要: There are mainly two different orbital information, namely broadcastephemerides and IGS final ephemerides (IGS rapid, ultra rapid, predicted andfinal ephemerides) used in the GPS positioning. The broadcast ephemerides usedin practice and real time are obtained through assessments derived from theobservations from the USA GPS reference stations. Broadcast ephemerides areformed (depending on GPS week) from satellite information and the accuraciesthey provide are adequate in many GPS applications. On the other hand, severalparameters (for example, information about gravity area, improved satelliteorbit information, etc.) need to be known in order to attain high accuracy inengineering and geodetic applications. Final ephemeris information can bedownloaded from the related web sites via the...
