In order to estimate the accuracy in fixing atmospheric sources in South-East Asia by means of the triangulation and the two-station's direction findings (DFs), we have made use of the measurements of the difference in propagation time at Toyokawa and Bangkok in Thailand. As the results, it is found that atmospheric sources in South-East Asia can be located by the triangulation DF network with a rather small error: When a specific atmospheric source is fixed with its cocked-hat** area being less than 1x10^4km2, the error in estimating the distance from Sakushima is less than ±15%. The corresponding error is less than ±20% for the fixed atmospheric source with its cocked-hat area of less than 5x10^5 km2. Furthermore, the location of atmospheric sources in South-East Asia by means of only two stations among the DF network is made possible within an error in distance of less than ±22%. But we have to make an appropriate choice on the combination of the stations; either Moshiri or Kagoshima is used along with Sakushima depending on the bearing angle measured at Sakushima.
