Sin gle  Epoch Ambiguit y Resolution Success Rates Under Modified Objective  Function Without Prior Baseline Information

  • In  this paperthe  traditional  objective  functionthe quadratic of  difference  of  float  ambiguity and  inte ger  ambiguit yis  re placed  by a modified function  called  sum of  L1and L2pure  carrier  phaseresidua  squares when searching for  a correct  inte ger  ambiguit y.The inte ger  ambiguities  search  space is  obtained by a floatin g transformation  and building observation model with DDdouble difference CA code  range and wide  lane  carrier  phase.The calculation  results  from 18-hour static GPS data  indicate  that  the modified is  better  than  the  traditional  objective  function  for  reliabilit y and usabilit y with a hi gher  success  rate.
