TY  - JOUR
AB  - Modeling  and  mitigating  carrier-phase  multi-path errors continue to be a significant challenge for high-accuracy positioning using global navigation satellite sys-tems. The multipath error is dependent on the operationalenvironment  and  therefore  cannot  be  mitigated  by  differ-encing  techniques.  The  effect  of  multipath  is  accentuatedwhen  observables  based  on  linear  combinations  of  mea-surements  from  two  or  more  frequencies  are  formulated.We develop a new carrier-phase multipath error observablethat  isolates  the  inter-frequency  carrier-phase  multipatherror for linear combinations of observables, such as wide-lane  (WL).  Real-time  kinematic  positioning  results  fromvarying  baseline lengths show that a significant reductionin  between  14  and  47 %  in  the  time  to  initial  ambiguityresolution  are  achieved  by  correcting  the  WL  observableusing the new carrier-phase multipath error observable.
