POSITION DETERMINATION METHOD, POSITIONING DEVICE, AND ELECTRONIC INSTRUMENT |
摘要 |
A position determination method includes: performing a positioning process that calculates a located position by performing positioning calculations using satellite signals; determining whether or not a convergence condition is satisfied based on current and preceding positioning results when the positioning process is performed, the convergence condition being specified as a condition for determining whether or not the positioning results of the repeated positioning processes have converged; and determining the located position calculated by the current positioning process to be an output position when the convergence condition is satisfied.
