IGS analysis centers provide satellite orbit solutions to the CDDIS using pre-determined schedules, e.g., sub-daily, daily, or weekly, depending upon the data product. The IGS …

IGS final orbits, clocks and ERPs: considered the highest quality and the most consistent IGS products, include daily combined satellite orbits. The IGS final ERPs are derived from the …

2020年11月1日 · IGS orbit and clock combination solutions are available in three forms: ultra-rapid, rapid, and final. The ultra-rapid product, useful for real-time and near real-time …

View and learn more about the global network of all IGS ground tracking stations. Access Station Guidelines, the Site Log Manager User Guide, and more. Products derived from GNSS data …

Analysis Centers (ACs) of the International GNSS Service (IGS) retrieve GNSS data on regular schedules to produce precise orbits identifying the position and velocity of the GNSS satellites. …

The use of the IGS orbit/clock products imply positioning, orientation and scale of a precise reference frame, so that PPP position solutions (with the IGS orbits/clocks held fixed) are …

International GNSS Service (IGS) analysis centers provide satellite orbit solutions to NASA’s Crustal Dynamics Data Information System (CDDIS) using pre-determined schedules, e.g., …

The Multi-GNSS Pilot Project (MGEX) has been set-up by the IGS to track, collate and analyze all available GNSS signals. This includes signals from BeiDou, Galileo, QZSS, and IRNSS, as …

The next plots show the daily Helmert scale, translation, and rotation parameters for the individual AC orbit solutions separately, with respect to the IGS Final products. The orbit rotation plots …

The plots below show the Weighted RMS and median differences (mm) of the IGS combined orbits with respect to the IGS RAPID products. These comparisons are performed over the full …
