Keywords:HF-START, Radio Propagation Simulator, Space Weather, Ionosphere

Dated back to early 2016, the radio propagation subgroup was started in the A01 group (Space Weather Forecast System) of the PSTEP (Project for Solar-Terrestrial Environment Prediction). This subgroup has been working on clarifying of space weather (ionosphere is particular) effect on the radio propagation. Day-to-day variation of the bottom side of ionosphere has great influence on availability and integrity of radio waves in high frequency (HF, 3-30 MHz) band. HF is used as a backbone of communication systems for aviation during en-route phase and for amateur radio during disaster relief operation. We, therefore, focused on the HF band. The radio propagation simulator named HF-START (HF Simulator Targeting for All-users' Regional Telecommunications) has been developed. Availability and integrity of HF band are expected to be provided through HF-START interface after receiving users’ input/ request. The HF-START project activity and its future operation plan will be overviewed in this talk.
