Integer Ambiguity Resolution For Precise Point Positioning

Summary And Further WorkVI Hotine-Marussi‣ With GPS data we demonstrated the uncalibratedphase delay is very stable. can be estimated preciselyand applied to ambiguity-fixing for PPP (94%).‣ By using PPP+Amb.Fix, a new strategy is developedfor very huge GNSS networks in order to savememory and computation time‣ Applicable to users with own PPP software forregional Network, where NL might be also a constant‣ It will improve PPP results, especially for Short TimeData and Moving Object, as well as ZTD/Slant Delay.‣ With increasing range accuracy and better IGSproducts, it might be able to challenge the currentVRS system.
