1. A positioning device comprising:

  • processing circuitry configured to;

    execute least squares method positioning by using, as an observation amount, n, n is an integer of 3 or larger, number of single difference amounts of an L1-wave pseudorange obtained from n pieces of observation data from n number of positioning satellites and n pieces of correction data corresponding to the n pieces of observation data,calculate a sum of squares of n residuals obtained for each positioning satellite by executing the least squares method positioning,normalize the n residuals,evaluate the calculated sum of squares and the normalized n residuals, andapply correction to the n pieces of observation data used for positioning based on the evaluation.
