Abstract
Provided is a positioning terminal of a global navigation satellite system configured to: receive a plurality of navigation signals and an augmentation signal from a plurality of navigation satellites and an augmentation satellite; acquire, in a process of causing each value of error causes including an ambiguity to converge through a plurality of times of observation to enhance an accuracy of positioning through continuous observation, each value of a position of the positioning terminal recorded in advance in a storage area to calculate each value of the error cause, and use the calculated each value as an initial value and/or one value to be added for the continuous observation to cause each value of the error cause to converge; and successively perform positioning calculation.
