Abstract
A signal processing apparatus includes circuitry configured to measure a relative displacement amount of the signal processing apparatus for each predetermined measurement period, measure a first delay time corresponding to a time period required for the signal processing apparatus to output a positioning solution, and estimate a position of the signal processing apparatus at a time after a current time by the first delay time, based on the positioning solution, the relative displacement amount for each measurement period, the first delay time, and a second delay time. A positioning server determines the positioning solution based on observation data related to a GNSS signal, and the second delay time corresponds to a time period from transmission of the observation data to the positioning server to reception of the positioning solution.
