Triple-Frequency GPS Precise Point Positioning Ambiguity Resolution Using Dual-Frequency Based IGS Precise Clock Products

Table 2

RMS of positioning results with fixed ambiguities and float ambiguities during the same period (after fixing ambiguities) for 10 6-minute sessions at redu and tlse. In the table, “float” means RMS of positioning error with float ambiguities, “fixed” means RMS of positioning error with fixed WL ambiguities, “—” means there is no corresponding float solution RMS for comparison, and “fail” means failure of fixing correct WL ambiguities during the session. The unit in this table is centimeter.
