Commencement of Shortwave Propagation Simulator (HF-START) Service
– Demonstrating radio wave propagation paths between any two points based on real-time space weather information –
March 24, 2021
National Institute of Information and Communications Technology
Highlights
- Demonstrate real-time shortwave propagation based on realistic space weather information.
- Estimate and visualize shortwave propagation between any two points on the Earth selected by the user.
- Web application-in-aid for shortwave broadcasting, aviation communications, amateur radio, etc.
Background

The radio wave propagation paths at 3, 6 and 9 MHz transmitted from Tokyo to Hokkaido, and from Tokyo to Kagoshima are shown. The radio propagation at 12 MHz is also calculated, but is not displayed because the 12 MHz does not reach the destination.
