    CAMSAT XW-4 (CAS-10) Scheduled for Deployment Today

    The CAMSAT XW-4 (CAS-10) satellite was launched into the Chinese Space
    Station on November 12, 2022 aboard China's Tianzhou-5 cargo spacecraft,
    and was launched by the Long March-7 Y6 launch vehicle from the Wenchang
    Launch Center in Hainan, China. It is currently planned that the XW-4
    (CAS-10) satellite will be separated from the Chinese space station and
    enter operational orbit at 01:30 UTC on December 18, 2022.

    The functions of XW-4 (CAS-10) satellite include UHF CW telemetry beacon,
    GMSK telemetry data transmission, V/U mode linear transponder, a visible
    light band space camera.

    After the satellite completes the in-orbit test and works normally, the
    space camera photo download will be open to amateur radio enthusiasts all
    over the world. When the relevant remote control command is received by the satellite, the GMSK telemetry channel will be used to downlink the photo storage information and photo data, and the telemetry data will stop
    sending at that time.

    XW-4(CAS-10) satellite adopts a 8U CubeSat structure with a mass of about
    12kg, an on-orbit envelope size of 1007x790x475mm with four solar array
    panels and a three-axis stabilized attitude control system is used,
    long-term power consumption is about 18.3 Watts.

    XW-4 Technical specifications are as follows:
    * CW telemetry beacon:
    Frequency: 435.575MHz
    RF power: 20dBm
    CW rate: 22wpm
    * GMSK telemetry:
    Frequency: 435.725MHz
    RF power: 23dBm
    Data rate: 4800bps
    * V/U mode linear transponder:
    Uplink frequency: 145.870MHz
    Downlink frequency: 435.180MHz
    RF power: 20dBm
    Bandwidth: 30kHz
    Spectrum inverted
    * Photo download remote control:
    Coming soon...

    Preliminary Keplerian elements, as supplied by CAMSAT are as follows:

    CAS-5A Designated Fengtai-OSCAR 118 (FO-118)

    On December 9, 2022, the CAS-5A satellite was launched on a Smart Dragon-3
    Y1 launch vehicle from the Chinese sea launch platform in the Yellow Sea.
    The Chinese Amateur Satellite Group (CAMSAT), working closely with local education authorities, designed, built, tested, and manages the CAS-5A satellite. Thirty-one students from ten high schools learned satellite
    design, manufacturing, and applications through educational courses
    initiated by CAMSAT and the Fengtai educational institution. The satellite carries V/u and H/u linear transponders, a V/u FM repeater, and CW and GMSK telemetry beacons for amateur radio use.

    At the request of CAMSAT and the CAS-5A team, AMSAT hereby designates the satellite as Fengtai-OSCAR 118 (FO-118). We congratulate all the involved teams, thank them for their contribution to the amateur satellite
    community, and wish them continued success on this and future projects.

    Administration Drafting Executive Order To Simplify Space Rules

    WASHINGTON, Dec 9 (Reuters) - U.S. President Joe Biden's administration is drafting an executive order intended to streamline approval for private
    rocket launches amid a broader effort to bring legal and regulatory clarity
    for American companies on everything from space travel to private space stations, according to two U.S. officials familiar with the effort.

    The order would be part of a push by the White House's National Space
    Council to modernize U.S. space regulation, which has failed to keep up
    with the increasingly ambitious pace of private-sector investment and development.

    The order, slated to be ready for Biden to sign by early 2023, is meant to simplify licensing procedures under existing laws for more routine space activities like launching rockets and deploying satellites

    Top Ten Most Needed of the 488 Gridmaster Grids, November 2022

    As of November, stations actively seeking the Gridmaster award who have reported their progress to KE0PBR -- owner of the Gridmaster Heat Map
    account on Twitter, and AMSAT rover page manager -- have indicated that the following are the most needed grids at this time:

    1. CM79
    2. DN35
    3. DN08
    4. CM89
    5. DN27
    6. DN24
    7. DN26
    8. DL79
    9. DM86
    10. DM76

    Satellite operations or roves in any of these grids would be VERY popular!

    Changes to AMSAT-NA TLE Distribution for December 18

    Two Line Elements or TLEs, often referred to as Keplerian elements or keps
    in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin
    files are updated Thursday evenings around 2300 UTC, or more frequently if
    new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/

    On December 9, 2022, CAMSAT's CAS-5A satellite was launched on a Smart
    Dragon-3 Y1 launch vehicle from the Chinese sea launch platform in the
    Yellow Sea. See AMSAT News Service Bulletin ANS-345 (Dated December 11,
    2022) for transponder data.

    Then, at the request of CAMSAT and the CAS-5A team, AMSAT has designated
    the satellite as Fengtai-OSCAR 118 (FO-118) on December 15, 2022. See Drew Glasbrenner, KO4MA and OSCAR Number Administrator's bulletin (above)) for details.

    Originally FO-118 was thought to be NORAD Cat ID 54682, but more recent TLE have revealed that CAS 5A is actually object 54684 (2022-167C). Thanks to
    Nico Janssen, PA0DLO, for the update on the correct NORAD Cat ID for FO-118 (formally CAS-5A).

    Therefore, the following satellite has been added to this week's AMSAT-NA
    TLE distribution:
    FO-118 NORAD Cat ID 54684.

    Spacewalk From ISS With Two Cosmonauts Cancelled

    The Roscosmos Mission Control team in Moscow postponed Wednesday eveningâ
    planned spacewalk with two cosmonauts to evaluate the situation and data
    from the Soyuz spacecraft. None of the crew members aboard the
    International Space Station were in danger, and all conducted normal
    operations throughout the day.

    Roscosmos is closely monitoring Soyuz spacecraft temperatures, which remain within acceptable limits. NASA and Roscosmos continue to coordinate
    external imagery and inspection plans to aid in evaluating the external
    leak location. Plans for an additional inspection of the Soyuz exterior
    using the station’s Canadarm2 robotic arm are underway.

    The leak was first detected around 7:45 p.m. EST Dec. 14 (0045z on Dec. 15) when data from multiple pressure sensors in the cooling loop showed low readings. At that time, cosmonauts Sergey Prokopyev and Dmitri Petelin were preparing to conduct a spacewalk. The cosmonauts did not exit the space station, and no crew members were exposed to the leaking coolant.

    The Soyuz MS-22 spacecraft carried NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin into space after launching
    from the Baikonur Cosmodrome in Kazakhstan on Sept. 21.

    [NOTE: All amateur radio equipment aboard the ISS is switched off during docking maneuvers and EVAs (spacewalks)]

    Amateurs and others around the world may listen in on contacts between
    amateurs operating in schools and allowing students to interact with
    astronauts and cosmonauts aboard the International Space Station. The
    downlink frequency on which to listen is 145.800 MHz worldwide.

    Maitland Air Cadet Association, Goderich, ON, Canada, direct via VA3SQN.
    The ISS callsign was NA1SS. The crewmember was Josh Cassada, KI5CRH.
    Contact was successful: Fri 2022-12-16 17:25:07 UTC 32 degrees elevation. Congratulations to the Maitland Air Cadet Association students and Josh!

    ESPRIT: Private Higher School of Engineering and Technology, Little Ariana, Tunisia, telebridge via ON4ISS. The ISS callsign is presently scheduled to
    be TBD. The scheduled crewmember is Josh Cassada, KI5CRH. Due to an EVA,
    the contact has been cancelled for: Wed 2022-12-21 08:45:59 UTC 84 degrees.
    The contact will need to be rescheduled.

    The crossband repeater continues to be active. If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume
    up, and talk on the crossband repeater. So give a listen, you just never
