    ARLS007 Chinese Amateur Radio Satellite Launches Delayed

    CAMSAT says the CAS-7A launch has been postponed until next May, and
    CAS-5A until next June.

    "Because of COVID-19, many things have been delayed," CAMSAT's Alan
    Kung, BA1DU, told ARRL. He said an announcement would be made closer
    to the announced launches.

    CAMSAT said last spring that CAS-7A would launch in mid-September;
    the launch has been postponed multiple times since first announced.
    CAS-5A was predicted to launch in October. Both satellites will
    carry two transponders that include HF, in a configuration similar
    to that of the Russian RS satellites decades ago.

    CAS-7A will be placed into a sun-synchronous orbit with an
    inclination of 98 degrees at 500 kilometers above Earth. The
    transponders will have a bandwidth of 30 kHz. According to the IARU
    amateur satellite frequency coordination page, the HF/HF linear
    transponder will uplink on 15 meters - 21.245 to 21.275 MHz, and
    downlink on 10 meters - 29.435 to 29.465 MHz. A CW beacon will
    transmit on 29.425 MHz. The HF/UHF transponder will uplink at
    21.3125 to 21.3275 MHz, and downlink at 435.3575 to 435.3725 MHz. A
    CW beacon for that transponder will transmit on 435.430 MHz.

    The CAS-5A nanosatellite, with a 6U form factor, carries two HF
    transponders and two VHF/UHF transponders. While in orbit, it will
    deploy the tiny CAS-5B femtosatellite, which will weigh just 0.5
    kilogram.

    The array of CAS-5A linear transponders will include HF/HF, HF/UHF,
    and VHF/UHF with 30-kHz passbands (except 15 kHz for the HF/UHF
    transponder).

    CAS-5A will include CW telemetry beacons on HF and UHF. The HF CW
    beacon will be at 29.465 MHz, and a UHF telemetry beacon will be at
    435.57 MHz. Other beacons include the HF/HF transponder beacon at
    29.490 MHz; the HF/UHF transponder beacon at 435.505 MHz, and the
    VHF/UHF transponder beacon at 435.540 MHz.

    Telemetry will be transmitted at 435.650 MHz. The V/U linear
    transponder will uplink at 145.820 MHz; the V/U FM transponder will
    uplink at 145.925 MHz. Terrestrial stations will access the
    transponders at 21.385 - 21.415 MHz.

    ARLS009 ARRL Comments in Orbital Debris Mitigation Proceeding

    ZCZC AS09

    Space Bulletin 009 ARLS009

    SB SPACE ARL ARLS009
    ARLS009 ARRL Comments in Orbital Debris Mitigation Proceeding

    In comments to the FCC, ARRL targeted two specific areas of concern
    regarding a Further Notice of Proposed Rulemaking (FNPRM) in IB
    Docket 18-313 - mitigation of orbital debris in the new space age.

    In an earlier phase of the proceeding, ARRL filed comments and met
    with FCC staff to discuss the proposed rules. In comments filed on
    October 9, ARRL focused on the areas of indemnification and maneuverability/propulsion. Indemnification places the liability for
    any possible damage from a satellite on an individual or entity.
    ARRL reiterated its assertion that, as a practical matter, an
    indemnification requirement "would seriously impair the ability of
    amateur and university experimenters to launch and operate
    satellites under US auspices" due to the potential liability and
    high insurance cost.

    The FNPRM can be found online in PDF format at, https://docs.fcc.gov/public/attachments/FCC-20-54A1.pdf .

    ARRL's comments cited a letter from University Small Satellite
    Researchers, submitted on behalf of 24 named professors last April,
    contending that the requirement "would effectively preclude a large
    proportion of academic SmallSat missions because public universities
    typically cannot legally enter into indemnification arrangements."

    ARRL argued that if the FCC does adopt an indemnification
    requirement, it should allow either the owner or the licensee of an
    amateur space station to provide indemnification. In the Amateur
    Satellite Service a licensee can only be an individual. An
    individual licensee is unlikely to accept liability for a satellite,
    but a satellite owner might. In its own comments, AMSAT similarly
    asked for language that would allow satellite owners as well as
    licensees to indemnify the US for the operation of an amateur radio
    satellite.

    The FCC proposal also would require that all space stations deployed
    in low-Earth orbits higher than 400 kilometers (about 250 miles) be
    able to maneuver with the use of some sort of onboard propulsion
    system. ARRL urged adoption of an exception for "a limited number of
    amateur and similar experimental satellites" that are below a
    specified size and mass and either standalone spacecraft or in a
    constellation of no more than four or five individual satellites.
    ARRL suggested a size limit of 36 x 24 x 12 centimeters and 12
    kilograms in mass.

    "This would accommodate the types of small satellites most often
    used for experimental purposes by radio amateurs," ARRL told the
    FCC. "Such satellites are small in number [and] have limited to no
    capacity to implement maneuverability using current technology due
    to their small size," yet provide valuable platforms for
    experimentation and student experience.

    Alternatively, ARRL asked the FCC to consider increasing the
    400-kilometer low-Earth orbit limit, since satellites placed into
    orbit from the ISS and from ISS service vehicles "often are in
    higher orbits but share the same characteristics as those that orbit
    below 400 kilometers." Doing so would help to preserve the
    educational and experimental benefit of such satellites, ARRL said,
    provided "such vehicles are shown to pose no risk to the
    International Space Station and will return to Earth within the
    specified time limit."

    In concluding its remarks, ARRL asked for "reasonable
    accommodation," given the public benefit of the Amateur Satellite
    Service, rather than lumping small experimenters and researchers
    with large corporate entities planning to launch thousands of
    satellites.

    ARLS010 Neutron-1 CubeSat Scheduled for Deployment on November 5;
    Other Sats Pending

    The 3-U Neutron-1 CubeSat is scheduled for deployment from the
    International Space Station (ISS) on November 5 at 10:40 UTC. For
    the satellite's first month and during its commissioning phase, the
    Neutron-1 beacon will transmit 1,200 bps BPSK telemetry every 60
    seconds on 435.300 MHz. Developed by the Hawaii Space Flight
    Laboratory (HSFL) at the University of Hawaii at Manoa (UHM), the
    satellite's payload includes a VU FM amateur radio repeater during
    available times and according to the spacecraft's power budget. The
    Neutron-1 science mission is spelled out in a formal paper,
    Neutron-1 Mission: Low Earth Orbit Neutron Flux Detection and COSMOS
    Mission Operations Technology Demonstration.

    More information can be found online at,
    https://www.hsfl.hawaii.edu/ .

    HSFL operates and maintains a satellite UHF, VHF, and L/S-band
    amateur radio ground station at Kauai Community College.

    The primary mission of Neutron-1 is to measure low-energy neutron
    flux in low-Earth orbit (LEO). The science payload, a small neutron
    detector developed by Arizona State University, will focus on
    measurements of low-energy secondary neutrons - a component of the
    LEO neutron environment.

    A number of other amateur radio satellites are expected to launch or
    be deployed in the next few months. AMSAT's RadFxSat-2 (Fox-1E) is
    expected to go into orbit by year's end on Virgin Orbit's
    LauncherOne vehicle. RadFxSat-2 carries a 30 kHz wide VU linear
    transponder.

    The Tevel Mission - a series of eight Israeli 1U CubeSats, each
    carrying a UV FM transponder - is expected to launch from India on a
    SpaceX Falcon 9 rocket in December. Also from the Herzliya Science
    Center is a 3U CubeSat called Tausat-1, which is scheduled to launch
    on a Japan Aerospace Exploration Agency (JAXA) ISS resupply mission
    in February for subsequent deployment. Tausat-1 carries an FM
    transponder.

    AMSAT-Spain (AMSAT-EA) reports that its PocketQubes, EASAT-2, and
    HADES, have been integrated for launch on a SpaceX Falcon 9 in
    December, while GENESIS-L and GENESIS-N have been integrated for
    launch on Firefly's Alpha rocket.

    Continues to Assess Status

    ARLS002 RadFxSat-2 Satellite Signals Detected, AMSAT Engineering
    Continues to Assess Status

    AMSAT reports that it's continuing to assess the status of the
    RadFxSat-2 / Fox-1E amateur radio CubeSat after a ham in Nevada
    reported hearing his CW signal weakly via the spacecraft's
    transponder on January 27. AMSAT Engineering and Operations was able
    to confirm the reports from Brad Schumacher, W5SAT, and determined
    that RadFxSat-2 is partially functioning, although signals are
    extremely weak.

    "We also appreciate those who joined in determining whether they
    could detect their own or other signals in recent passes today,"
    AMSAT said in a January 28 bulletin. "Please do not attempt to
    transmit through the transponder until further notice. This is very
    important to the next steps we are taking now."

    The next crucial step in evaluating the condition of RadFxSat-2 is
    to determine whether or not the 1200 bps BPSK telemetry beacon is
    operating and, if possible, to copy telemetry from the beacon. AMSAT
    continues to ask that those with 70-centimeter receive capability
    listen on the beacon frequency of 435.750 MHz, +/- Doppler, upper
    sideband (USB). Use FoxTelem to capture any telemetry, and set
    FoxTelem to "Upload to Server" so that AMSAT will receive the
    telemetry data.

    Recordings are welcome, with a detailed description, at,
    foxtelem@amsat.us .

    FoxTelem can be found at, https://www.amsat.org/foxtelem-software-for-windows-mac-linux/ .

    AMSAT stressed that keeping the RadFxSat-2 / Fox-1E transponder
    clear "is essential to putting all power and attention to the beacon telemetry." Available data suggest that RadFxSat-2 is OBJECT M from
    the Virgin Orbit LauncherOne launch, NORAD ID 47320, international
    designation 21-002M.

    "We thank the amateur satellite community for their perseverance and
    assistance while the AMSAT Engineering and Operations teams work to
    understand and resolve the situation with RadFxSat-2," AMSAT said.
