    AMSAT CubeSatSim First Official Release – v1.0

    I am very pleased to announce the first software release of the CubeSatSim software v1.0! Along with the first hardware release v1.0 last month, this
    is an important milestone for this AMSAT educational project.

    All the CubeSatSim software and hardware is fully open source. The v1.0 release info is available on GitHub here: https://github.com/alanbjohnston/CubeSatSim/releases/tag/v1.0 and the v1.0 hardware info including gerber files is available here: https://github.com/alanbjohnston/CubeSatSim/tree/v1.0/hardware/v1.0

    Thanks to Bruce Paige, KK5DO, we have CubeSatSim blank PCB sets and
    CubeSatSim Raspberry Pi SD cards available on the AMSAT Store. For the
    moment, they are only available to ship to US addresses. In a post-COVID future, we hope to offer worldwide shipping.

    The CubeSatSim Raspberry Pi SD Card is a 16 GB micro SD card with
    Raspberry Pi OS Lite and all the CubeSatSim software installed and
    configured on it. It is available at the AMSAT Store for $20 https://www.amsat.org/product/amsat-cubesatsim-raspberry-pi-sd-card/ You
    can also download the image and flash it to your own SD card using these instructions https://github.com/alanbjohnston/CubeSatSim/wiki/2.-Software-Install Here

    AMSAT FoxTelem Version 1.11 Released

    I am releasing version 1.11 of FoxTelem. This primarily supports new
    features needed for GOLF-TEE development and the CubeSatSim. If you are
    using FoxTelem in the lab or classroom then this release should be
    installed. It also fixes several bugs that will help with live decoding of AO-95. It is not a mandatory upgrade but it is recommended.

    Specifically it addresses the following:
    * Fixes a bug where Costas decoding can stop if audio is being monitored
    * Supports all the latest features needed for the CubeSatSim
    * Better warnings for tracking and Find Signal errors
    * Supports all the latest GOLF-TEE layouts
    * Fixes a bug where strong signals may not be tracked correctly
    * Supports math expressions in telemetry conversions
    * Better handles USB device errors

    You can download FoxTelem here: http://amsat.us/FoxTelem/windows/FoxTelem_1.11g_windows.zip http://amsat.us/FoxTelem/linux/FoxTelem_1.11g_linux.tar.gz http://amsat.us/FoxTelem/mac/FoxTelem_1.11g_mac.tar.gz

    Feel free to reach out to me with questions or comments.

    AMSAT Pacsat Ground Station Version 0.43 Released

    I'm releasing an update to the Pacsat Ground Station. This version
    - Parses the MO-112 FailSafe beacons and saves them for analysis.
    - Fixes a bug where FalconSat-3 telemetry data could not be downloaded from
    the server
    - Defaults FalconSat-3 to not check Pacsat File Header checksums. This was annoying for partially downloaded files.

    You can download it here:

    [ANS thanks Chris Thompson, G0KLA/AC2CZ, AMSAT Pacsat Ground Station
    Developer, for the above information]


    FalconSat-3 Update

    I had sufficient WiFi to check out FalconSat-3 thisvaround 1200 UTC 8 July 2021. Thankfully, only the TX had gone off and a reload right now isn't necessary.vIf I can make the time, I'll look over the telemetry logs and
    see if we had a low voltage trip or something, but not sure.

    Users---until further notice, please limit the size of your uploaded files
    to around 10k or less. Just before the bird went silent, numerous large
    files were being uploaded and downloaded. I cannot say for sure if this is related to the recent issue, but let's call it a hunch.

    In the meantime, FalconSat-3 is again open for BBS and digipeater use -
    please limit file upload size to 10K or less.

    Long Live PCSAT (NO-44) (and PCSAT-11)

    Some (current) APRS Amateur Satellite history:

    CONSTRUCTION: For what it is worth, After 20 years, both PCSAT side A and
    B transponders (digipeaters) remain semi-operational as the longest running student project satellites in space. Further they were built desk-top style using simple off-the-shelf Kantronics KPC-9612 TNC's and Hamtroncs kit
    TX/RX boards. All parts are COTS and chips are in sockets. Batteries are AA NiCd's. There are no CPU's on board. All command/control/telemetry is just
    what is inherent in the TNC's. Only thing we did was replace all
    electrolytic caps with tantalums. Having no clean room, we just used kem
    wipes and alcohol to wipe off all the fingerprints and dust before bagging
    for delivery.

    NOTE: No one should be so cavalier if their mission is REAL and costing
    great amounts of expectations and money. Back then it was just a free ride
    with no expectations other than student involvement.

    SAFE MODE (NOT): The only thing wrong was stupid thinking on the power
    budget. As our first satellite, we put on dual A/B systems AND additional
    9600 baud DUAL UHF backup link receivers so that we had QUAD backup command
    RX capabilities in case of failures. The problem was we decided that all systems must come up on power-up in order to have access to all the
    redundant backup reset and command capabilities if needed and (DUH!), if
    all was OK, we would turn off the unnecessary backup-UHF receivers and un-crossconnect the transmitters.

    TOO-COMPLEX LOGON: That is what kills it (on every orbit). If the reason
    it reset is because of low battery, then the last thing you want is for EVERYTHING to be ON when you are coming into the sun and trying to charge
    back up. There is not yet enough power to get the command in to command off
    the unnecessary systems! Further, the commands required a full two-way
    AX.25 connection requiring 5 packets to exchange the password challenge and password response. All of which fully loaded the cross-connected XMTRs
    while trying to recover power.

    NO CPU or OPERATING SYSTEM: PCSAT had no programmable CPU. Just
    two-dual-port TNCs and 2 VHF XMTrs and 2 VHF RCVRS, and 2 UHF 9600 baud
    RCVRS. There was nothing in which to put SMART-safe-mode power-up thinking. Hence the fatal flaw to just power up everything and command later...

    WITH LUCK: But luckily, the orbit occasionally has short eclipses and
    longer sun side (about 1 hour) which gives it enough time to sometimes
    have enough power to do a few user digipeats. Though after only a few, that usually kills the battery for the rest of the orbit. We long since gave up trying to go through the entire secret logon process to try to turn off the extra UHF receivers, only to have it last another' 10 minutes or so until
    the next eclipse and so that is why it just does its thing and sometimes
    people are successful, or not.

    MISSION: Side A of PCSAT (AKA W3ADO-1) remains operational on 145.825 digipeating when power permits. Same for side B which has a digipeater with
    a 144.39 MHz downlink for use over North America which at the time was
    thought would be useful for communicating *TO* normal 144.39 travelers who
    may be traveling outside of range of the terrestrial network for a while.

    TODAY (June 8, 2021), one of our sysops tested the side "B" and confirmed
    it remains operational. That is why you might occasionally see PCSAT-11 in
    the APRS logs. Although within the rules at the time of launch, in the last decade, the IARU has officially made notice that operation of satellite downlinks in the old 144.30-144.40 range are no longer authorized. Besides,
    we never came up with a good use of the side B anyway. (Broadcast an APRS message to all North American mobiles, or special traffic to a specific mobile).

    Of course, we learned those lessons and had 6 successful followon APRS satellites with only the last two (PSAT and PSAT2) had programmable CPUs
    (BASIC Stamps). See http://aprs.org/sats.html

    Changes to AMSAT TLE Distribution for July 8, 2021

    The following satellite has been added to this week's AMSAT TLE

    TUBIN - NORAD Cat ID 48900 (Thanks to Nico Janssen, PA0DLO for the identification.)

    The following satellite has been deleted from this week's AMSAT TLE Distribution:

    STAR-Me Mother - NORAD Cat ID 43640 (Decayed June 26, 2021)

    Drew Glasbrenner, KO4MA (OSCAR Number Administrator) announced July 3, 2021
    in AMSAT News Service Bulletin ANS-185 that MIR-SAT1 has been designated MIRSAT-OSCAR 112 or MO-112.

    Thus, MIRSAT1 (NORAD Cat ID 48868) is now shown as MO-112 in this week's
    TLE distribution.

    AMSAT's GOLF Program is about getting back to higher orbits, and it all
    begins with GOLF-TEE – a technology demonstrator for deployable sol
    panels, propulsion, and attitude control, now manifested for launch on
    NASA's ELaNa 46 mission. Come along for the ride. The journey will be
    worth it!

    Upcoming Satellite Operations

    Quick Hits:

    VP2V/K3TRM: I will be operating from Tortola, BVI as VP2V/K3TRM on July
    4-17, 2021. Activity will be on 40-6M SSB & digital, and satellite.

    EN57/67: @SeanKutzko KX9X and @Nancy_N9NCY will celebrate Sean’s bi
    in the Michigan’s Keweenaw Peninsula July 15-19. Look for them on F
    M and
    SSB satellites, with the possibility of some Parks On The Air activity as
    well. They will also hit EN57/67 on 7/14&19 on the Yooper Rove.

    K0JM, Monday, Tuesday, Wednesday (July 12-14) I’ll be on the north
    shore of
    Lake Superior. I hope to get in at least one pass in each of the grids:
    EN36, EN46, EN47, EN48, EN57 and EN58. But this will be holiday style, so
    no guarantees. Mostly linears, but some FM perhaps.

    Major Roves:


    July 11 DN25 daytime passes
    July 12 DN27 with a guest Gridmaster hopefully
    July 13-16 DN28 holiday style
    July 17 DN38 holiday style

    July 21-23 DN54 holiday style
    July 25-27 DN64 holiday style
    July 30-31 DN63 holiday style

    July 11 & 18 will all be planned trips just for Sat passes FM and SSB. I
    will try to publish passes ahead of time on Twitter and QRZ. The remainder
    of the trip will be camping in remote areas with little to no internet or Twitter. I will get info out as I can, but I won’t be able to setup
    ahead of time. Lots of POTA activations on Sats and HF as well.
