Телеметрию уже принимают Japanese ground stations worked out together to receive a UNITEC-1 signal. 1st pass over Japan kept from 16:15(JST) to 25:15(JST) at 21st May.
- Measured Frequency 5839.91 MHz (Original UNITEC-1 downlink frequency 5840.000MHz) - Problem: big QRH is measured during major and minor downlink (wide-range recorder may be needed) - Orbital determination downlink is easier to receive
