The multi-frequency and multi-GNSS PPP phase bias estimation and ambiguity resolution, which is accomplished by a unified model based on the uncombined PPP, are thoroughly evaluated with special focus on Galileo and BDS. 606 $aSatellites 615 0$aSatellites. 676 $a523.98 700 $aXiao$b Guorui$01278658 801 0$bNjHacI 801 1$bNjHacl 906 $aBOOK 912 $a9910627228503321 996 $aMulti-frequency and multi-GNSS PPP phase bias estimation and ambiguity resolution$93013675 997 $aUNINA
