BY70-1 CubeSat in lower orbit
A CZ-2D rocket carrying the amateur radio FM transponder satellite
BY70-1 was launched from the Taiyuan Space Launch Center on Wednesday,
December 28 at 03:23 UT
It had been planned it would go into a 530 km circular Sun-Synchronous
Orbit (SSO) but instead the orbit appears to be 524 x 212 km which
will give an orbital lifetime of just one or two months.
Paul Stoetzer N8HM reports working Wyatt Dirks AC0RA through the FM
transponder during the 1709 UT pass on December 28. Paul says “Uplink
requires precise frequency adjustment and there’s a delay on the
downlink, but the signal is strong”.
A recording of the FM transponder can be heard at
BY70-1 is a 2U CubeSat project for school education and amateur radio.
It features 3-axis stabilization and deployable solar panels. In
addition to the FM transponder BY70-1 has a camera and it is planned
to download images and telemetry via a 9600 bps BPSK downlink.
The IARU amateur satellite frequency coordination pages list these frequencies:
• 145.920 MHz uplink
• 436.200 MHz downlink
