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

At present, clock and orbit precise products used in UPD's generation are from CODE final products. More than 150 reference stations from IGS and MGEX networks are selected for UPD estimation. The automatic UPD estimation scripts would be carried out at UTC 12:00 each day as before. Daily extra-wide-lane (EWL), wide-lane (WL) UPDs and epoch-wisely narrow-lane (NL) UPD at 30-sec intervals including BDS-3 are released about 3.5 hours later.
