BDS-3 UPD products released

On May 31, 2021, uncalibrated phase delay (UPD) products for BDS-3 was officially released by iGMAS Innovation Center.

Multi-frequency observable-specific signal bias (OSB) products

The multi-GNSS and multi-frequency observable-specific signal bias (OSB) products provided by iGMAS Innovation Center was officially released on October 24, 2020. The released OSB products include daily code biases as well as phase biases at 30-second intervals for four systems: GPS, GLONASS, Galileo and BDS.

Trial operation of LEO precise science orbit products started

Precise orbit determination of LEO satellites is of central importance for many applications of geodesy and Earth science. iGMAS innovation center provides precise science orbit (PSO) products for LEO satellites, including GRACE Follow-on, Swarm, Jason-3, Sentinel-3, etc.

Official release of Multi-GNSS real-time clock products

Precise satellite clock product is an important prerequisite to support real-time precise positioning service. To fully promote the capability of multi-GNSS RTPPP, iGMAS innovation center provides multi-GNSS (GPS, GLONASS, BeiDou and Galileo) real-time clock products with 5 s sampling(see <a href="{{url_for('main.products_detail',context='Multi-GNSS_Real-time_Clock')}}">here</a> for more details).

Multi-GNSS uncalibrated phase delay (UPD) products released

On June 19, 2020, the multi-GNSS and multi-frequency uncalibrated phase delay (UPD) products provided by iGMAS Innovation Center was officially released for global users. At the same time, UPD product automatic generation management system began trial operation and the UPD estimation would be carried out at UTC 12:00 each day. The released UPD products include daily extra-wide-lane (EWL) and wide-lane (WL) UPDs & epoch-wisely narrow-lane (NL) UPD at 30-sec intervals of four systems: GPS, GLONASS, Galileo and BDS. More than one hundred reference stations from IGS and MGEX networks are selected for UPD estimation. See <a href="{{url_for('main.products_detail',context='Uncalibrated_phase_delay')}}">here</a> for more details about our UPD product.

Multi-GNSS rapid and ultra-rapid orbit products published

Precise orbit product of GNSS satellites is officially published on June 15, 2020. It includes rapid and ultra-rapid orbits of current five GNSS, namely BDS (including BDS-2 and BDS-3), GPS, GLONASS, Galileo and the regional QZSS. The rapid products are provided at 13:00 UTC every day with a latency of 37-hours. The ultra-rapid products are updated every 2-hours with 24-hour post-processed arc and additional 24-h forward-predicted arc. The released products are both at 300-sec intervals.
