“…Most available long term HF propagation models, e.g., VOACAP, ICEPAC, and the International Telecommunication Union (ITU) Recommendation 533 (REC533) propagation model, use monthly median values of f o F2 and M(3000)F2 obtained from worldwide maps established using historical data at various ionosonde sites around the world. The commonly used world maps include the International Union of Radio Science (URSI) and International Radio Consultative Committee (CCIR) maps [ Tanyer and Erol , ]. The CCIR maps, used in VOACAP and ICEPAC, are based on monthly median values obtained by the worldwide network of ionosondes from about 150 stations during 1954–1958.…”

“…Many software methods used to predict ionosphere variables which classified in groups such that Statistical, empirical and numerical software methods. The most widely used statistical method is Voice of America and Ionospheric Communication Enhanced Profile Analysis and Circuit Prediction Program (VOACAP) [5,6,7,8,9,10,11]. The novelty of this paper is to use real data variables such as fof2 (the critical frequency of the F2 layer of the ionosphere) and h'f2 (virtual height of F2 layer) supplemented by Nicosia Ionosonde station (35.1856° N, 33.3823° E) 1000 km away from Baghdad and using sets of empirical equations implemented by MATLAB to generate the values for a single hope information parameters like MUF (Maximum Usable Frequency),FOT (Operating Frequency) and d (the radio range distance) then compare the theoretical results by using VOACAP to predict MUF and coverage area in which Baghdad station is the transmitter.…”
