Abstract :
This paper deals with Holt-winter method to forecast ionospheric delay of a day based on the past and current TEC observations. The delay is forecasted by considering IRI-2007 model data. Results show that the error between the forecasted and the actual ionospheric delay value is about 3 to 6 % for IRI data. The method applied here can be extended to forecast ionospheric delay for any geographic location.
