    Launch Window for AMSAT's RadFxSat-2/Fox-1E Opens December 19, 2020


    Virgin Orbit has announced that the launch window for their

    LauncherOne Launch Demo 2 mission opens on December 19. This launch

    will carry AMSAT's RadFxSat-2/Fox-1E to orbit.


    RadFxSat-2, like RadFxSat/Fox-1B, now AMSAT-OSCAR 91, is a

    partnership opportunity between Vanderbilt University and AMSAT and

    will carry a similar radiation effects experiment, studying new

    FinFET technology.


    RadFxSat-2 is the fifth and final Fox-1 satellite built by AMSAT. The

    RadFxSat-2 spacecraft bus is built on the Fox-1 series but features a
    linear transponder "upgrade" to replace the standard FM transponder

    in Fox-1A through D. In addition, the uplink and downlink bands are

    reversed from the previous Fox satellites in a Mode V/u (J)

    configuration using a 2 meter uplink and 70 cm downlink. The downlink

    features a 1200 bps BPSK telemetry channel to carry the Vanderbilt

    science data in addition to a 30 kHz wide transponder for Amateur

    Radio use. Telemetry and experiment data can be decoded using

    FoxTelem version 1.09 or later. FoxTelem is available at

    https://www.amsat.org/foxtelem-software-for-windows-mac-linux/.


    Participation in telemetry collection by as many stations in as many

    parts of the world as possible is essential as AMSAT Engineering

    looks for successful startup and indications of the general health

    and function of the satellite as it begins to acclimate to space.

    AMSAT will send a commemorative 3D printed QSL card to the first

    station capturing telemetry from RadFxSat-2.

    RadFxSat-2 / Fox-1E Frequencies:


    Telemetry Downlink - 435.750 MHz

    Inverting Linear Transponder Uplink - 145.860 MHz - 145.890 MHz

    Inverting Linear Transponder Downlink - 435.760 MHz - 435.790 MHz

    FoxTelem 1.09 Released

    Chris Thompson, G0KLA/AC2CZ announced the availability of

    FoxTelem 1.09. This release provides several enhancements and needed

    changes for RadFxSat-2/FOX-1E. This new spacecraft sends 1200bps

    BPSK telemetry in parallel with a linear transponder. Downloading

    telemetry and sending it to the server will assist AMSAT and the

    Radiation tolerance experiments from Vanderbilt University.

    You can download FoxTelem 1.09 at:

    http://amsat.us/FoxTelem/windows/FoxTelem_1.09n3_windows.zip

    http://amsat.us/FoxTelem/linux/FoxTelem_1.09n3_linux.tar.gz

    http://amsat.us/FoxTelem/mac/FoxTelem_1.09n3_mac.tar.gz



    The changes from 1.08 to 1.09 are as follows:
    * Performance improvements on the telemetry tabs. This uses less CPU

    than 1.08.

    * Clearer display of historical records on the telemetry tabs for RT,

    MAX, MIN and WOD.

    * Bug fixes for Fox-1E decode and display of diagnostic tables,

    Whole Orbit Data, and formatting of telemetry.

    * Ignore extra commas in conversion curve comments.

    * Allow a single spacecraft to be downloaded from the Fox Server,

    even if FoxTelem stores many spacecraft.
    * Latest Golf-T layouts for development.

    * BPSK CRC checksum calculation for GOLF-T.

    * Another new way to decode and display the mode.

    * More generic tab layouts to allow future expansion through soft

    coding.

    * Throttle the DDE requests when decoder stopped.
    * Many other bug fixes

    On Saturday, December 5, 2020, Chris added the following information:

    "If you are having difficulty upgrading to FoxTelem 1.09 because it

    says that it can not write some files, then I have put together a

    procedure to migrate your data. If in frustration you reset the

    FoxTelem properties file and now you don't have your old telemetry

    from 1.08, then this will still likely work and recover the data.

    Details are at: https://www.g0kla.com/foxtelem/tutorial_moving_foxtelem_logfiles.php

    "Many thanks to Frank K6FW who helped work out this procedure. Feel

    free to reach out to me for help."


    Burns Fisher, WB1FJ adds, "For those of you with Fox-In-A-Box

    telemetry stations (Fun Cube Dongle in a Raspberry Pi with FoxTelem

    software), FoxTelem 1.09 has been successfully tested on an FIAB.

    "It is easy to update your FIAB with the new FoxTelem version. Some

    time ago, I provided the instructions for upgrading to a new FoxTelem

    and they will not have changed significantly other than the version

    numbers. You can view the instructions at:

    https://tinyurl.com/ANS-341-FIAB-Upgrade.


    "In any case, over the next few days, I will update and post the
    instructions as well as making the new version available on the FIAB

    SD cards sold in the AMSAT store and (a bit after that) on the free

    download."

    IARU Coordinates Frequencies for Three Satellites in November

    During the month of November the IARU coordinated frequencies for

    three upcoming Amateur Radio satellites:

    + GASPACS
    The primary mission is to deploy a one meter long inflatable UV

    curable boom (AeroBoom) from a 1U CubeSat in low-Earth orbit and to

    photograph the deployed AeroBoom and transmit a clear picture back

    to earth. GASPACS will also operate an AX.25 automatic digipeater for

    Amateur Radio testing and communication purposes.


    All of the code that the satellite and ground station runs will be

    open source and published to Github (except telecommand encryption)

    allowing Amateurs to use the knowledge and code for their own

    projects. The UHF downlink uses 9k6 2GSK with AX25. Planning a CSLI

    deployment from the ISS in Q1 2022. A downlink on 437.365 MHz has

    been coordinated More info at http://gas.usu.edu and

    https://tinyurl.com/ANS-341-GASPACS

    The link to the Github documentation can be found at:

    github.com/SmallSatGasTeam/CubeWorks.


    + SMOG-2

    SMOG-2 is a 3p PocketQube continuation of SMOG-P and SMOG-1 spectrum

    monitoring pocketqube class satellites with wider monitored spectrum

    range focused on HAM, ISM and broadcasting bands. Worldwide Amateur

    Radio stations can receive its spectrum monitoring data to help

    create a global electromagnetic pollution map to be published at

    http://gnd.bme.hu. The UHF downlink uses 5kb GMSK. Planning a

    RocketLab launch from New Zealand into a 600 km SSO in 2021. A

    downlink on 437.150 MHz has been coordinated.


    + D3
    The mission is a 2U CubeSat intended to demonstrate the performance

    of a novel drag-based targeted point re-entry algorithm using

    repeatedly deployable/retractable drag surfaces to perform orbital

    maneuvers that guarantee spacecraft re-entry at a pre-defined

    location. If successful, the D3 module can be adapted to other

    Amateur Radio satellites to ensure consistent re-entry and help

    reduce the concentration of space debris. The mission is run solely

    by Amateurs with the purpose of helping future Amateur missions. The

    UHF downlink uses 9k6 GMSK downlink for AX25 telemetry and data and

    1k2 AFSK for a beacon. Planning a launch to the ISS in

    September 2021. Downlinks on 437.080 MHz and 2432.000 MHz have been

    coordinated. More info from http://adamus-d3-website.herokuapp.com/.

    Orbital Mechanics for Dummies

    Orbital Mechanics has been around since well before artificial

    satellites were even remotely possible. (Remember that

    Johannes Kepler who gave us Keplerian elements we use in tracking

    satellites today published his book, The Cosmographic Mystery, in

    1596! And Walter Hohmann first described transfer orbits in 1929.


    Rendezvousing with another object in the same orbit is perhaps the

    most counterintuitive, as you must adjust your orbital period by

    leaving the shared orbit and later re-entering it. To "slow down" you

    accelerate to increase the height of your orbit, lengthening your

    orbital period relative to the other craft, let time pass, and then

    re-enter the original orbit once they've caught up. Conversely, to

    catch up, you decrease velocity to achieve a smaller, more eccentric

    orbit, which has a shorter orbital period.


    There are tons of resources out there for diving into the math of

    orbital mechanics. Surprisingly, one of the easiest to read comes

    from the FAA's Office of Aerospace Medicine as part of their

    "Advanced Aerospace Medicine On-line" course at:
    https://bit.ly/3oaOSzM.


    You can also play with orbits in a simulator at:

    https://orbitalmechanics.info/.

    Or, if you really want to develop a more intuitive sense of two-body

    orbital mechanics while having a blast (pun very much intended), play

    the Kerbal Space Program (not a free game) at:

    https://www.kerbalspaceprogram.com/game/kerbal-space-program/.

    Brandmeister DMR Network Announces Password Implementation

    The AMSAT DMR talkgroup is 98006 on the Brandmeister Network.

    Walter Holmes, K5WH, has received notice of changes coming to

    Brandmeister from the network administrators:

    "Due to issues that have been happening recently, we are going to

    need to start requiring users to set a hotspot security pass-word to

    gain access to the US Masters. If you already have a hot spot

    security password set on the BM portal, you can ignore this post.

    We are going to start requiring this on master these US master

    servers:

    - 3101 changes on December 1
    - 3102 changes on December 4
    - 3103 changes on December 11

    "This is already implemented on the RU masters, and other Master

    Servers will follow. At this time this will just be for hotspots. The

    API is being worked on to allow repeater owners to make this change

    as well, but it is not quite ready to go."

    Walter noted, "Since we all use the US DMR Master servers, 3101,

    3102, or 3103, they will be changed starting as early as

    December 1, 2020, requiring a HotSpot PASSWORD be set, or you will no

    longer be able to use DMR. Whether you have a Hotspot, BlueDV,

    DudeStar, DroidStar, or ANY of the other applications to access DMR,

    these change is required."

    Be sure to log into the Brandmeister site, and create an account

    right away if you don't already have one, as it may take a few days

    to get that authorized: https://brandmeister.network/

    For instructions on how to set your hotspot security on

    the Brandmeister portal visit https://tinyurl.com/ANS-341-DMR.


    In conclusion Walter said, "If you're not comfortable with these

    steps, help is available via a Zoom channel. Reach me at

    k5wh@k5wh.net for the link."
