Demonstration of high-speed data transmission in amateur radio band and on-orbit shape measurement system. |
| Description |
“HIROGARI” has two main missions to be achieved.
Many of the nano-satellites launched so far adopted the data transmission rates of 1200 or 9600 bps in the UHF or VHF amateur radio bands. In this mission, we will downlink data not only with 1200 bps AFSK and 9600 bps GMSK but also with 13600 bps GMSK and 19200 bps 4FSK. “HIROGARI” is equipped with a two-dimensional unfolding structure based on the “Miura-ori” , which is a method of folding a flat surface such as a sheet of paper into a smaller area, and will deploy it in space. It will also carry an optical surface measurement system using a two-dimensional grid to demonstrate its usefulness. This project will demonstrate the deployment structure and the measurement method in space for the first time in the world. |
