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
[ANS thanks AMSAT for the above information]
--------------------------------------------------------------------
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."
