This study investigates the dependence of the theoretical success rate of the fast and reliable integer ambiguity resolution in GPS/GNSS double/triple-frequency carrier-phase relative positioning on its baseline length. It estimates the success rate under the condition using up to 14 navigation satellites (i.e., seven GPS and seven Galileo ones). Single-differentiated ionospheric delay is regarded as an error under the conditions of nonvanishing baseline length with regard to the reference and rover receivers. The calculation results show that such many visible satellites remarkably improve the success rate compared with that under the condition using only seven visible GPS satellites. The use of triple-frequency measurements improves the success rate only under the condition of less than 7km baseline length.
