In use of NNSS system, several methods have been published to avoid the ionospheric effect even on one-wave receiver. This paper describes an evaluatian of the differential system using the data obtained from two fixed stations, one, which is main station, has two-wave receiver and the other, which is sub-station, has one-wave receiver near the main station. The obtained data were adjusted and a correction was made on a measured position of substation. The evaluations were made by month, time, maximum elevation angle of satellite. Consequently the standard error of sub-station is considerably converted as to longitude such as 1/2-1/3 comparing with non-corrected position by month and time, and as to latitude the average value is considerably converted by maximum elevation angle. Problems such as means of delivery of correction value and its coverage for practical purposes, are yet to be solved in the future.
