    OMOTENASHI is Struggling to Carry Amateur Radio to the Moon

    OMOTENASHI, a project of the JAXA Ham Radio Club, was a secondary payload aboard NASA's Artemis 1 mission, launched on November 16. It plans to land
    on the surface of the moon, and to transmit a beacon in the amateur 70cm
    band.

    Controllers have reported OMOTENASHI is tumbling, making it difficult for
    the spacecraft to charge its batteries and communicate with the ground. Of
    the ten cubesats flown as secondary payloads, seven are operation, two have
    not been heard from, and OMOTENASHI is struggling. Controllers are
    continuing recovery attempts.

    OMOTENASHI is derived from Outstanding MOon exploration TEchnologies demonstrated by NAno Semi-Hard Impactor. Omotenashi is also a Japanese word
    for hospitality.

    JAXA Ham Radio Club planned to utilize the flight demonstration opportunity
    of the OMOTENASHI mission to conduct the following amateur radio missions:
    (i) To conduct technological research with respect to receiving ultra-weak
    UHF signal from a space probe toward the moon
    (ii) To conduct an outreach activity providing amateur radio operators all over the world with an opportunity to try to receive signals from moon
    region.

    OMOTENASHI is a 6U-CubeSat with external dimensions of 239 x 366 x 113mm
    and an approximate mass of 14 kg.

    OMOTENASHI consists of three modules: orbiting module, retro motor module,
    and surface probe. During the moon transfer orbit, these modules are integrated. When OMOTENASHI arrives at the moon, the surface probe will be separated and conduct semi-hard landing.

    If control is regained, OMOTENASHI will be actively controlled by
    ultra-small attitude control system including star tracker, sun sensor,
    IMU, reaction wheel, and cold gas jet thruster. During the moon transfer
    orbit, OMOTENASHI may be spin-stabilized due to the strict resources. For further details, please see: https://www.isas.jaxa.jp/home/omotenashi/JHRCweb/jhrc.html

    There will be UHF CM/PSK/PM/PSK31 beacons, with 1 watt RF, on both the
    orbiting module and the surface probe. CisLunar explorer, MIT KitCube and
    Lunar IceCube are expected to share the same launch.

    Amateur Radio Operators and More Will Track NASA's Artemis 1

    Amateur radio operators will join a powerful international network tracking NASA's Orion spacecraft.

    NASA officials announced that a network of 18 volunteers, organizations and space agencies will assist with tracking Artemis 1, which will send an
    uncrewed Orion spacecraft to orbit around the moon after blasting off from Earth atop a Space Launch System (SLS) rocket. Launch occurred on Nov. 16.

    The selected volunteers, including two individuals in the amateur radio community, will "demonstrate whether they can receive Orion's signal, and
    use their respective ground antennas to passively track and measure changes
    in the radio waves transmitted by Orion," NASA officials said in a
    statement Oct. 31.

    NASA collected the proposals in a Request for Information released in
    August. Data the participants pick up will be sent to the agency's Space Communications and Navigation (SCaN) program. The goal is to improve
    tracking information for future deep-space missions, NASA officials stated. NASA, of course, will also gather its own tracking data on Orion.

    Selected volunteers from the amateur radio community include:
    Non-profit: CAMRAS, Netherlands
    Academic institutions: Space Systems Design Laboratory, Georgia Tech Research Institute, U.S.
    Private citizens: Scott Chapman, K4KDR (U.S.) and Scott Tilley, VE7TIL (Canada)

    New Groundstation Software Available for GreenCube

    As of Nov. 18, a total of 135 stations digipeated via the Italian GreenCube satellite. These stations represent 31 DXCC entities. Stations now report
    using various combinations of software to operated through the satellite.
    One constant is using SatPC32ISS for antenna tracking and doppler
    correction.

    The S5Lab GreenCube team software is a bit more complicated and at the beginning that was all that was available. It used three programs,
    including GNURadio, GreenCubeTNC and GreenCubeDigi.

    However, UZ7HO quickly created the digi app and custom soundmodem after the S5Lab release, most everyone has migrated to UZ7HO now. Note: UZ7HO has
    updated the program from time to time, so download it again once in a while
    to get the updates. It is available at: https://uz7.ho.ua/greentnc.zip
    (There are both FM and SSB soundmodems included in the package, but the FM
    one can ignored, as all are using USB-D for both uplink and downlink.) Note matching the rig bandpass filter with the Soundmodem one (900-2100 Hz)
    helps to have a better S/N particularly if you have local QRM.

    The radio will interface with soundmodem via a soundcard or virtual audio cable. Soundmodem.exe is located in the \greentnc\usb directory, and is a separate program. This program needs to be configured to connect with your radio’s audio interface. The digipeater software is in the client
    directory, called GreenCubeDigi.exe. GreenCubeDigi automatically connects
    to soundmodem via TCP. So you should have two programs running, one the TNC
    and the other the digi “terminal.”

    Ops may add GetKISS+ software, by Mike Rupprecht, DK3WN, in order to
    upload received packets to SatNOGS. This isn’t necessary, but it do
    es help
    add coverage for telemetry. This software is a bit tricky to get working,
    but once you have one of Mike’s programs running other programs wil
    l work
    without any issues. Mike’s software can be found here: https://www.satblog.info/software/

    Doug Papay, K8DP, recommends installing GetKISS+ v1.4.1 (he could not get v1.4.2 to work). It requires VB6 runtime, which should already be
    installed, and the ActiveX OCX controls need to be registered. See: https://www.pe0sat.vgnet.nl/decoding/tlm-decoding-software/dk3wn/ for instructions on how to do this. Make sure to run the command prompt as Administrator when performing the regsrv32.exe commands. Also, do not
    delete or move the OCX files after registering them. (The OCX files should
    be placed in C:\Libraries\OCX folder)

    Mike also has a GreenCube Telemetry Decoder that you can download—i
    t is a
    nice program that graphically displays the telemetry. He has also added a digipeater message display and list of unique callsigns heard—a nic
    e
    feature.

    The config.ini files will need to be updated to reflect your station
    details. These files are located in the folder where you keep GetKISS+ and GreenCube Telemetry Decoder.

    GetKISS+ and GreenCube Telemetry Decoder connect via TCP to the soundmodem
    all using the same IP (localhost) and port number.

    Some have been confused by the lack of an ACK message after transmitting a packet to the satellite. It is sent only if the Tx delay is used. However,
    it is better to use Tx delay 0 for real-time QSOs to avoid unnecessary transmission by the bird (saving on-board power). With Tx delay 0 you will receive your own message as an acknowledgement.

    Release Date of CAS-10/XW-4

    AMSAT-China, or CAMSAT, http://www.camsat.cn, has announced December 18 as
    the release date for CAS-10/XW-4. Photos of this satellite may be seen at: https://twitter.com/bd5rv/status/1592978613204586496 and https://twitter.com/bd5rv/status/1593693879798497285

    As previously reported by ANS, CAMSAT’s CAS-10/XW-4 satellite was l
    aunched
    on November 12, 2022, carried on the Tianzhou 5 cargo spacecraft to the
    Chinese Space Station. The satellite will be active immediately upon
    deployment into its own 400 km orbit with an inclination of 42.9 degrees. CAS-10 carries a VHF uplink and UHF downlink linear transponder with a bandwidth of 30kHz. Downlink frequencies for VHF/UHF linear transponder
    435.180 MHz, for UHF CW telemetry beacon 435.575 MHz and for GMSK telemetry 435.725 MHz. Also an uplink for the transponder 145.870 MHz have been coordinated.

    U.S. High School CubeSat to be APRS Relay

    TJREVERB, a 2U CubeSat built by Thomas Jefferson High School for Science & Technology, has been frequency coordinated to operate as an APRS relay on 145.825 MHz. It is scheduled for launch on the SpaceX Falcon 9 rocket and Dragon spacecraft set to deliver additional science, crew supplies, and hardware to the International Space Station next week. The satellite will
    be released from ISS at a later time.

    The first U.S. high school to send a CubeSat to space back in 2013, Thomas Jefferson High School for Science and Technology’s Research and Edu
    cation
    Vehicle for Evaluating Radio Broadcasts satellite aims to study the use of iridium as a primary radio communication method. Additionally, the
    satellite will demonstrate using a passive magnet onboard and the Earth
    s
    magnetic field for stabilization rather than using an attitude
    determination and control system for pointing accuracy and stabilization
    for iridium. What makes this satellite even more notable is that it was a system’s engineering project. The students selected space-grade par
    ts,
    wired the electronics for the satellite, wrote the drivers to control the different systems, and coded the flight software.

    “What’s special about TJREVERB isn’t necessarily th
    e mission, it’s what we
    did. These kids literally built a satellite the way the industry would
    build a satellite; we selected parts from vendors and got those parts to
    work together,” said Kristen Kucko, robotics lab director and the s
    chool’s
    space faculty advisor. “This is an engineering feat.”

    CAPSTONE Arrives to Orbit at the Moon

    The CAPSTONE mission operations team confirmed that NASA’s CAPSTONE spacecraft arrived at its orbit at the Moon Sunday evening. The CubeSat completed an initial orbit insertion maneuver, firing its thrusters to put
    the spacecraft into orbit, at 12:39 UTC on Nov. 13.

    CAPSTONE is now in a near-rectilinear halo orbit, or NRHO. This particular
    NRHO is the same orbit that will be used by Gateway, the Moon-orbiting
    space station that will support NASA’s Artemis missions. CAPSTONE i
    s the
    first spacecraft to fly an NRHO, and the first CubeSat to operate at the
    Moon.

    In the next five days, CAPSTONE will perform two additional clean-up
    maneuvers to refine its orbit. After these maneuvers, the team will review
    data to confirm that CAPSTONE remains on track in the NRHO.

    CAPSTONE – short for Cislunar Autonomous Positioning System Technol
    ogy
    Operations and Navigation Experiment – is a precursor to the Gatewa
    y
    project to establish a crewed space station in orbit around the moon.
    AMSAT, along with our ARISS partners, is developing an Amateur Radio
    package, including two-way communication capability, to be carried on-board Gateway in lunar orbit.

    Changes to AMSAT-NA TLE Distribution

    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/

    No changes for this week.

    Satellite Shorts From All Over

    + The latest episode of the ARRL On the Air podcast features details from
    avid satellite operator Sean Kutzko, KX9X, about how to get started on the amateur satellites -- an activity that's available to hams of all license classes. Sean's article, "Ham Radio Satellites: Reliable, Accessible, and Enjoyable" is also the cover piece of the November/December issue of ARRL's
    "On the Air" magazine. (ANS thanks ARRL Letter for the above information)

    + A cargo spacecraft successfully docked with the International Space
    Station Nov. 9, despite making its two-day trek through space with only one functioning solar panel. The Cygnus spacecraft, which was carrying 8,200
    pounds of science experiments and supplies for the astronauts on board the
    ISS, lifted off from NASA’s launch site in Wallops Island, Virginia
    , atop
    an Antares rocket on Nov. 7. A few hours after Cygnus reached orbit, one of
    the spacecraft’s two solar arrays failed to deploy, NASA announced.
    NASA
    and Northrop Grumman, which designed and built the Cygnus capsule, opted to abandon efforts to open the array in order to focus on carrying out a safe rendezvous with the ISS, noting that the spacecraft already had sufficient power to finish its journey. (ANS thanks CNN Space & Science for the above information)

    + SpaceX launched one of its reusable Falcon 9 rocket boosters for the last time Saturday on a rare expendable mission for Intelsat, devoting all of
    the launcher’s propellant toward placing a pair of television broad
    casting
    satellites into orbit. Intelsat says it paid SpaceX an additional fee for
    the expendable mission. The Falcon 9 rocket lifted off at 11:06 a.m. EST
    (1606 GMT) Saturday after a four-day delay caused by Hurricane Nicole. The booster debuted March 2, 2019, with the first unpiloted test flight of SpaceX’s Crew Dragon capsule. The booster was not fitted with Space
    X’s
    recovery hardware, such as titanium grid fins or landing legs. And SpaceX
    did not deploy one of its drone ships for the expendable mission. (ANS
