Students involved in the Clark sat-1 project
Clark sat-1 (AMBITIOUS), callsign JS1YLT, is scheduled to deploy from the International Space Station (ISS) on Monday, December 18, 2023, at 10:15 GMT. The IARU coordinated downlink is 435.130 MHz.
Clark sat-1 (AMBITIOUS) CubeSat
Clark sat-1 is a 1U size satellite is an educational project of students at the Clark Memorial International High School in Japan. As of November 30 approximately 50 students have been involved in the project and a number have an amateur radio license. The satellite will carry out these missions:
1. Optical Camera Mission
Take photos of the Earth and will downlink them in the 435 MHz band (GMSK, 4,800 bps). The downlink schedule will be posted on X (@sat1_AMBITIOUS).
2. Digi-talker Mission
Downlink 40 to 120 seconds long Digi-talker NBFM signal (Voice message or SSTV pictures in Robot 36 format recorded before launch) including the call sign and school name. communications.
In addition to the 4k8 AX25 GMSK telemetry and mission data there will be a CW beacon every two minutes.
Through these missions, the students will be able to improve their amateur radio and satellite communication skills.
The project will also serve as a model showcase for the development of amateur satellites by the younger generation, and stimulate the interest of the younger generation in amateur radio and satellite
We would appreciate if you will report the reception to “clarksat-1@clark.ed.jp” after receiving those signals.
