The SpaceX F9 Transporter-10 Rideshare mission has been scheduled for
launch on 1 March 2024. In addition to a half dozen commercial payloads,
two amateur satellites are on the launch manifest: SONATE-2 from Germany
and CroCube from Croatia.
*SONATE-2*
SONATE-2 is a 6U CubeSat designed and built by the University of Wuerzburg
in Germany. As for many university satellites, the mission objectives of
the SONATE-2 satellite can be divided into three different parts:
โ The operation of an amateur radio payload
โ The development and operation of the satellite for the education of
students.
โ The operation of a novel payload as a technology demonstration in space.
The amateur payload of SONATE-2 consists of a VHF transceiver that was
already built for the predecessor mission SONATE over the course of several
student theses. For SONATE-2 additional student theses extended the
transceiver functionalities. It will provide regular SSTV downlinks with
images from the optical sensors included in the AI payload as well as an
APRS digipeater and CW beacon.
On the education side, the mission will serve as a foundation for different
aspects of the university aerospace and computer science engineering
program. In the context of practical courses, theses or as student
assistants, students can participate in the development of all subsystems
of the space and ground segment, including the amateur radio payload and
the technology demonstration payload. In the context of mandatory lectures
and exercises on space operations every student will also be included in
the operations of the satellite. The German Aerospace Center (DLR) offers a
School Lab for high school students at the location of our external ground
station in Neustrelitz, Germany.
Besides experiments on space and satellites, the School Lab includes
amateur radio contacts to the ISS under the supervision of licensed local
radio amateurs, which they wish to extend to other satellites like in this
cooperation with the SONATE-2 mission.
In addition to the amateur and educational mission parts, the SONATE-2
mission also has a research objective for the demonstration of novel
artificial intelligence technology in the space environments. While the AI
payload is mainly operated using a separate up/downlink in the space
operation service in S-band, the satellite bus and the amateur payloads are
operated in the amateur service. Housekeeping telemetry in the amateur
service also contains status information of the non-amateur payload.
Proposing CW, SSTV using Martin M1 and APRS downlinks on VHF and a 9k6
G3RUH AX25 telemetry downlink on UHF. Planning a launch into a 550 km
Sun-Synchronous Orbit (SSO). More info at https://go.uniwue.de/hk.
Downlinks on 437.025 MHz, 145.825 MHz, 145.840 MHz and 145.880 MHz have
been coordinated by the International Amateur Radio Union (IARU).
*CroCube*
CroCube is a 1U CubeSat mission to support the Croatian, but also worldwide
amateur radio community with many HAM services and activities. The
missionโึs goal is also to facilitate the technological development of
Croatia, create an advanced society focused on prosperity and innovation,
and increase participation in the global space sector. Also, drive Croatia
into the space era, increase interest in astronomy and space projects, and
develop STEM and tech entrepreneurship, create a platform for founding a
space center in Croatia, increase investments and employment in robotics,
technology and ICT and finally reduce unemployment and prevent brain drain.
The CroCube satellite is designed for HAM radio activities. The main
purpose is to provide services for radio amateurs in Croatia and worldwide,
and also for students of technical universities to get hands-on experience
with satellite communication and get radioamateur licences. One of the
project goals is to popularize HAM activities across the common population,
students and children in Croatia.
CroCube will provide these HAM services:
โ AX.25 telemetry
โ CW beacon โ Digipeater
โ Anniversary/special occasions AX.25 & CW messages for community engagement
โ Experimental SSDV transmissions
โ SATNOGS integration, decoder, dashboard
Proposing a UHF downlink using 9k6 G3RUH GFSK with AX25 telemetry. Planning
an Exolaunch deployment into a 510 km SSO. More info at
https://drustvo-evo.hr . A downlink on 436.775 MHz has been coordinated by
IARU.
