    • PROBLEM TO BE SOLVED: To detect ionosphere abnormality in a satellite navigation system, by using observation data of only one frequency, without being affected by a base length between a reference station and a monitor station.SOLUTION: An observation equation is constituted in which a full navigation satellite is utilized with SD ionosphere delay, SD carrier phase bias, and SD receiver timepiece error as state parameters by determining a carrier phase and an inter-receiver single difference of ionosphere free linear coupling of observation data for a code pseudo distance and a carrier phase of only one frequency in satellite data acquired by a reference station and a monitor station. A float solution of the observation equation is determined by estimating the state parameter for each epoch in accordance with a least square principle, the SD carrier phase bias is converted into DD, a candidate of an integer solution of DD carrier phase bias is determined according to an integer indefiniteness determination approach. A fix solution of the observation equation is determined by implementing a calibration on the candidate, the estimated SD ionosphere delay and SD receiver timepiece error between the reference station and the monitor station are corrected, and ionosphere abnormality is detected by the finally obtained SD ionosphere delay.
