FOR IMMEDIATE RELEASE<\/p>\n\n\n\n

Fram2Ham SSTV Simulation on ISS<\/p>\n\n\n\n

February 1, 2025<\/strong>\u2014The ARISS international team has devised a proficiency training SSTV
(Slow Scan Television) exercise to prepare all SSTV image receivers for what to expect on the
upcoming Fram2 mission.
Fram2 Mission and Fram2Ham Payload Overview
Fram2 is a pioneering private astronaut mission, the first to fly astronauts over the North and
South poles. Fram2 will give the four on-board astronauts unprecedented first views of the polar
regions from space. While astronauts on the ISS can see a large portion of the Earth, it is not
possible to see these upper regions of Earth from the ISS. Fram2 is planned to be launched no
earlier than March 1, 2025 and is planning a 3 day mission with an optional 2 day extension.
The amateur radio experimental payload on Fram2, called Fram2Ham, is also pioneering in
nature. It represents the first use of human spaceflight amateur (ham) radio in polar orbit and
the first amateur radio transmissions from a SpaceX Dragon capsule. Fram2Ham operations are
being performed by private astronaut Rabea Rogge, amateur radio callsigns LB9NJ (Norway)
and KD3AID (USA).
Fram2Ham will transmit Slow Scan Television (SSTV) picture images from space to radio
receivers on the ground as part of a high school and university student competition.\u00a0These
SSTV images can also be received by radio enthusiasts (hams, educators, and youth)
worldwide and posted to the ARISS SSTV Gallery\u2014but with a twist. Images posted will not be
shown until after the Fram2 mission. These operations support the youth SSTV competition,
where they are to acquire several SSTV \u201cPuzzle Pieces,\u201d assemble the puzzle, determine the
polar location, and answer questions related to that location.
For more information on the Fram2 mission and for youth organizations interested in
participating in the Fram2Ham SSTV competition, see: f2.com<\/a> and Fram2Ham.com<\/a>. ARISS also
has a Fram2 tab on its website www.ariss.org.<\/p>\n\n\n\n

Fram2Ham SSTV Simulation on ISS
The ARISS international team is planning an SSTV event to help all participating to be as
proficient as possible in acquiring images from Fram2Ham and submitting them in the SSTV
gallery. Like previous SSTV events, ARISS will provide special commemorative certificates for
those who upload images to the gallery. Certificates will be delivered after the completion of
both the Fram2 simulation event and the Fram2 mission.
SSTV Simulation details
ARISS radio: The Kenwood TM-D710GA transmitter will be set to low power (5 watts vs. 25
watts for previous SSTV events). This is to simulate the challenges and unknowns of a new
radio system on a Dragon capsule that might be in an unfavorable attitude in some parts of the
mission flight path.
Operations Frequency: 437.550 MHz. Using the SSTV (public downlink) planned for
Fram2Ham, ground users can practice the more challenging 70 cm doppler correction.
SSTV Mode: PD120. The longer image capture for this simulation (120 seconds, vs. 36
seconds for Fram2Ham\u2019s Robot 36 SSTV mode) will allow ground users to hone their signal
polarization switching skills (manually and electronically) as well as precise antenna pointing.
Operations Duration: February 13 (World Radio Day) to February 17, 2025. This long duration,
over a weekend, will allow users multiple passes to practice, learn lessons, make corrections,
and try again.

Summary
Fram2Ham will be an exciting, first of its kind, mission and the first ham radio operations in a
space capsule. Fram2Ham signal propagation will not be fully understood until the mission
starts and ground users report their results. Since variations of antenna orientation are expected
during the mission, SSTV downlinked signals might be heard to the right or left of the flight path,
during the ascending or descending part of the flight path or beamed to space instead of to
Earth. In addition, Fram2 will be a short, 3-day, mission duration, with maybe 1-2 higher
elevation passes per day and with a startup several hours after launch and shutdown several
hours before reentry. These challenges require operating proficiency and the use of the best
attainable radio station. Our Fram2Ham pioneers need to be prepared and proficient. Are you
up for the challenge?<\/p>\n\n\n\n

About ARISS:
Amateur Radio on the International Space Station (ARISS) is a cooperative venture of
international amateur radio societies and the space agencies that support the ISS. In the United
States, sponsors are the American Radio Relay League (ARRL), Amateur Radio Digital
Communications (ARDC), Radio Amateur Satellite Corporation (AMSAT), NASA\u2019s Space
Communications and Navigation program (SCaN) and the ISS National Lab\u2014Space Station
Explorers. The primary goal of ARISS is to promote exploration of science, technology,
engineering, the arts, and mathematics topics. ARISS does this by organizing scheduled
contacts via amateur radio between crew members aboard the ISS and students. Before and
during these radio contacts, students, educators, parents, and communities take part in hands-<\/p>\n\n\n\n

on learning activities tied to space, space technologies, and amateur radio. For more
