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:
    https://www.amsat.se/2020/12/03/radfxsat-2-fox-1e-uppskjutning-19-december-2020/#respond
    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
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

IARU Coordinates Frequencies for Six Satellites in October

During the month of October the IARU coordinated frequencies for six
upcoming Amateur Radio satellites:

  • OreSat0 (Portland State Aerospace Society at Portland State
    University is a 1U CubeSat. The mission is to provide flight heritage
    to the ”OreSat bus”, an open source card-cage based system that is
    ideally suited for education CubeSat projects involving
    interdisciplinary teams of students. Downlinks on UHF using CW
    beacon, 9k6 G3RUH AX25/APRS packet beacon and a 96k GMSK
    engineering downlink. Also downlink on S Band using amateur 802.11b
    DPSK with 11M chip/sec spread and 1 Mbps data rate for bulk mission
    data. Downlinks on 436.500 MHz and 2425.00 MHz have been
    coordinated. Planning a launch with Momentus Space from Cape
    Canaveral in February 2021 into a 450 km polar orbit. More info at:
    http://oresat.org/ and https://github.com/oresat.
  • TartanArtibeus-1 (Carnegie Mellon University) is a 1P PocketQube.
    The
    Amateur Radio community globally will be provided with a delay
    ping-back service, allowing Amateurs to send messages, with replies
    from the satellite transmitted later. A UHF downlink using 3kbps FSK
    compatible with RadioHead library. A downlink on 437.170 MHz has
    been coordinated. Planning a SpaceX launch from KSC in December 2020
    into a 550km SSO.
  • SATLLA-2 (Ariel University) is a 2P picosat that will take
    low-resolution photos and will broadcast the photos over the Amateur
    Radio with its position in orbit and data from its sensors. UHF and S
    Band downlinks using LORA from 476bps to 9k6 bps. Downlinks on
    437.250 MHz and 2401.000 MHz have been coordinated.Planning a SpaceX
    launch into a 410 km 52 degree orbit in December 2020.
  • CSIROSat-1 (University of South Australia & CSIRO) is a 3U CubeSat
    mission that will perform hyperspectral infrared imaging of the earth
    for scientific research purposes. An experimental two-way link for
    Amateur Radio operators to exchange short messages through a
    ‘ping-pong’ arrangement of data exchange is among the several
    communications experiments. Proposing a 9k6 FSK downlink. A downlink
    on 437.315 MHz has been coordinated. Planning a launch from Cape
    Canaveral in March 2021 into an ISS orbit.
  • PyCubed-1 (Carnegie Mellon University) is a 1P PocketQube that will
    test a novel 3-axis attitude control system based on magnetic torque
    coils. In addition, it will test new low- power LoRa radios in
    low-Earth orbit which will be of interest to many other Amateur Radio
    small satellite operators. Proposing a 3kbps UHF downlink. A downlink
    on 437.290 MHz has been coordinated. Packets are standard LoRa format
    and are compatible with the RadioHead library. Planning a SpaceX
    launch from KSC into a 550 km SSO in December 2020.
  • Grizu-263A (Zonguldak Bülent Ecevit University) is a pocketcube
    satellite with a digipeater mode that will allow forwarding of
    received messages back to earth to support communication between
    Amateur Radio operators. Proposing a UHF downlink using 4k8 FSK. A
    downlink on 437.190 MHz has been coordinated. Planning a SpaceX
    launch from Vandenberg into a 500 600 km SSO in December 2020.
