Update on the Status of RadFxSat-2 / Fox-1E

From ANS-024:
RadFxSat-2 was launched Sunday, January 17, on Virgin Orbit
LauncherOne launch vehicle. Reports from the launch provider stated
that telemetry confirmed that the deploy commands had been sent and
that all of the doors opened successfully, resulting in payload orbits
that were all within the ICD limits.

Nominally, we expected to see “First (digital) Veronica” from the
RadFxSat-2 telemetry beacon commencing 54 minutes after our deployment
from the launch vehicle. That did not occur as expected.

For each of our launches, we follow a number of steps documented in
the “In Orbit Checklist” (IOC) spreadsheet. Confirmation of launch
and deployment are the first steps and then, confirmation of beacon
reception. All other steps follow that but there are steps in case of
anomaly, beginning with the detection of the beacon.

As always, from the moment we are deployed we look for signs of the
beacon through the ears of amateur radio operators and other means,
SatNOGS and webSDR to name a few. The antenna deployment and full
start of the IHU to bring up the beacon can occur anywhere around the
globe. AMSAT greatly appreciates the ongoing and reliable help we
receive from you and it is by far the best satellite ground network
even beyond that of many commercial players, for LEO orbits.

Command coverage is limited to the United States for various reasons
including regulatory requirements, so the opportunity to exercise the
steps of the IOC occurs a few times per day as the orbit passes over

With no sign of the beacon after a few orbits offering good footprints
for reception, we proceeded with the contingency steps to verify the
presence of or activate the beacon. This past week our Engineering
and Operations Team members have been at work literally 20 hours per
day exercising all of the contingencies outlined in the IOC steps.
These steps have grown and matured with each launch of a Fox-1 program
CubeSat and are tailored to the specific satellite. RadFxSat-2, while
she may seem to be much the same as the others with the exception of
the transponder vs. FM radio, does present a number of variations to
be included in the IOC. As the results of those steps were exhausted
with no beacon detected, we added meetings and increased emails
including all of our engineers to discuss possible causes by any of
the systems and to develop further steps.

From those we drew new steps of command sequences that might overcome
whatever anomaly existed and make the beacon heard. As the week drew
on, we continued brainstorming and steps to activate other functions
that would provide proof of life. We continue to do so today and for
whatever time until we exhaust all possibilities that we are able to
draw from the expertise and satellite experience of our Engineering
Team and Operations Team drawing from the design of RadFxSat-2 and
lessons learned in the Fox-1 program as well as any from missions
prior to AMSAT’s first CubeSats.

AMSAT still needs your help as always, to help detect any sign of
activity from RadFxSat-2. This includes ability to listen for local
oscillators or transponder driver output in the case of a failed PA.

I personally ask that those of you who are and have been interested in
the entire process of bringing a new amateur radio satellite to orbit
and through end of life to continue to contribute your curiosity and
enthusiasm in exploring from your own station, to pursue the
possibilities of a successful RadFxSat-2 mission along with us. I
have received reports and queries from some of you, and I greatly
appreciate your contributions. You are in fact volunteers in the
AMSAT Engineering Team through your contribution.

If you are interested, I ask that you do due diligence in your
procedure if you think you have identified a signal by re-creating (if
possible) and verifying to yourself that what you have is credible, as
we do, before contacting us. That “standard” procedure is what adds
value by making the information actionable rather than placing the
onus of determining if it is even real upon us, because we are of
course quite busy with that already. Please email your findings to
foxtelem@amsat.us and allow us a day or two to acknowledge and/or

While we tend to talk about our involvement with RadFxSat-2 above all,
a real effect reaches outside our mutual desire for amateur radio
satellite fun. RadFxSat-2 is sponsored by Vanderbilt University as
part of our long partnership going back to Fox-1A. RadFxSat-2’s
mission belongs to Vanderbilt University as part of their RadFX series
of missions seeking to verify and explore radiation effects on COTS
components. Their mission coincides well with AMSAT’s desire to fly
lower cost satellite missions using COTS components, in the unfriendly
radiation environment of Earth orbit and beyond. Vanderbilt also
sponsored the CSLI for RadFxSat (one) in our Fox-1B spacecraft back in

  1. Their proposal was selected by NASA, flown on the ELaNa XIV
    mission in November of 2017.

RadFxSat’s mission was very successful in the information provided
through the combined telemetry-gathering of all of those who pursue
our missions through FoxTelem. Vanderbilt University published their
results giving praise to AMSAT and our Fox-1 CubeSats. The experiments
we host are built by students and Vanderbilt shares the experiences
with the educational community in their area. That is a success for
AMSAT as well in our goal to provide STEM and other educational

While the RadFxSat-2 mission is problematic at this time, we will
pursue every possibility to make her work for the amateur community
and for our partner. I certainly hope to continue our partnership
with Vanderbilt, the mutual benefit is a wonderful and fun undertaking
that adds to the value of our satellites.


Satelliter på gång 2021 Q1

En liten titt i närtid 2021 Q1

För de som är tvåvägskommunikationsintresserade finns några nya LEO satelliter i första kvartalet 2021, dvs. satelliter som har nån typ av transponder eller digipeater.

Först ut, satelliter att hålla ett öga på de närmaste veckorna och månaderna Jan-Feb-Mar 2021 är:

  • Grizu-263A: är en pocketQube (5x5cm dvs. halva storleken av en cubesat 10x10cm) som har en UHF digipeater på 437.190 MHz
    sätts i bana med Falcon9 kanske i Januari 2021
  • Tevel Mission: 8 st cubesats som skickas upp, oklar om alla eller några av satelliterna har en U/V FM transponder UL 145.970 MHz / DL 434.600 MHz
    Sätts i bana med Falcon9
  • Kitsune: är en 6U cubesat, har ingen transponder men däremot C-band och UHF RX/TX där detaljerade 2M pixel bilder på jorden kan begäras och laddas ned i C-bandet
    Här finns det möjligheter att ha en C-band markstation med nedlänk och upplänk på 5.6Ghz
    IARU region1 bandplanen(C-band) för satellitupplänk är 5.650-6.668 GHz, nedlänk 5.830-5.850Ghz
    Sätts i bana med ISS
  • Hiapo: en cubesat, skulle ha haft en V/H digipeater men själva digipeatern blev nog inte klar ?
    däremot är satelliten fortfarande intressant eftersom den kommer ha experiment som genererar telemetridata på 437.225 MHz för magnetfält, solfläckars inverkan vilket kan vara kul nu när solcykeln tar fart
  • EASAT-2: är en pocketQube (5x5cm) och har en FM/FSK V/U linear transponder, UL 145.875 MHz / DL 436.666 MHz (ingen subton)
    Sätts i bana med Falcon9
  • Hades: är en pocketQube (5x5cm) och har en FM/FSK V/U linear transponder, UL 145.925 MHz/ DL 436.888 MHz (ingen subton)
    Sätts i bana med Falcon9
    EASAT-2 och Hades är från samma projekt och har snarlika data
  • Tausat, en 3U cubesat, har en V/U FM transponder, UL 145.??? MHz / DL 436.400 MHz
    Sätts i bana med ISS troligen 2021-02
  • RadFox Fox-1E, har en linjär V/U transponder, se tidigare nyhet på AMSAT SM:
    Sätts i bana med LauncherOne
  • MIR-SAT1: en cubesat, har en Digipeater UL 145.9875 MHz / DL 437.925 MHz
    Sätts i bana med ISS Februari 2020

Det händer ofta att satelliter ”skjuts upp” 😉 i tiden – så man får hålla sig uppdaterad i respektive systems kalendrar och efter lyckad uppskjutning vilken amatörradiosatellit identitet och keplerdata dom får.

Fyra olika system används för att sätta ovanstående LEO satelliter i omloppsbana.

  • ISS och nån typ av launch via experimentmodul eller manuell launch av ISS austronaut
  • SpaceX Falcon9, en lite större raket, Falcon9 där första steget landar igen och återanvänds
  • Firefly Alpha, en betydligt mindre raket än Falcon9 men tillverkad i kolfiber
  • Virgin Orbit LauncherOne, en liten raket som avfyras från vingen från Cosmic Girl som är en Boeing 747-400

I respektive systems uppskjutningsschema letar man upp respektive satellit.

Ett mycket stort antal LEO satelliter med enbart UHF telemetri nedlänk på amatörradiofrekvenser kommer sättas i bana under hela 2021.
Om man gillar att ta emot, avkoda data samt mata databaser med telemetridata kommer det finnas många tillfällen till det!.

Sen in i 2021 Q2 och framåt i tiden finns ytterligare ett par intressanta transponder/digipeater satelliter som är planerade att skjutas upp.
Låt se när dessa blir klara och återfinns i någon av systemens uppskjutningskalendrar.

RadFxSat-2 / Fox-1E uppskjutning 19 december 2020

Den sista satelliten i AMSAT-NAs FOX-serie, RadFxSat-2 / Fox-1E, har fått ett uppskjutningsfönster som börjar den 19 december (2020). Till skillnad mot de andra FOX-satelliterna, som har haft FM-transponder, har Fox-1E en linjär inverterande transponder för SSB och CW-trafik.

Dessutom har telemetrilänken flyttat till 70cm på 435.750 MHz och kan tas emot med den senaste versionen av FoxTelem.

Launch Window for AMSAT’s RadFxSat-2 / Fox-1E Opens December 19th

Virgin Orbit has announced that the launch window for their
LauncherOne Launch Demo 2 mission opens on December 19th. 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

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

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
