    Spain's URESAT-1 Collaborative Satellite Launches on SpaceX Transporter-8

    The URESAT-1 satellite, also known as HADES-B according to its ITU
    designation, successfully launched into space as part of the SpaceX Transporter-8 mission from Vandenberg AFB on Monday, June 12. The satellite
    is a joint effort between AMSAT-EA, URE (the Spanish equivalent of ARRL), private companies, and universities.

    The URESAT-1 satellite, contained within the D-Orbit ION Orbital Transfer Vehicle (OTV), was not deployed directly from the Falcon-9 rocket. Instead, approximately one hour and twenty minutes after launch, the Falcon-9 released the OTV, which will orbit the Earth for several days before deploying
    URESAT-1, along with other satellites.

    One of the primary objectives of URESAT-1 is to serve as an FM voice and FSK data repeater. Equipped with a Slow Scan Television (SSTV) camera, the satellite will transmit live images as well as stored images at regular intervals. It also features a chess game, enabling players on Earth to engage in a game against the satellite. Periodically, the satellite will transmit updates on the state of the game, including the chess board, the last
    movement made, and whether the next move belongs to the players or the satellite.

    The specified frequencies for communication with URESAT-1 are as follows: for uplink transmissions, 145.975 MHz or 145.925 MHz (auxiliary frequency) using
    FM voice without subtone, FSK 50 bps, AFSK, AX.25, APRS 1200/2400 bps. For downlink transmissions, the frequency is set at 436.888 MHz, and modes
    include FM voice, CW, FSK 50 bps telemetry, SSTV Robot 36, and a voice beacon with the callsign AO4URE.

    To provide further information regarding URESAT-1's transmissions, the
    AMSAT-EA organization has made available a comprehensive document that can be accessed at the following link: https://www.amsat-ea.org/app/download/13366685/AMSAT+EA+-+URESAT-1+Transmissions+description.pdf

    For those interested in decoding the telemetry, a Linux x86/ARM decoder is available for download at the following link: https://www.amsat-ea.org/app/download/13395017/URESAT-1_telemetry_decoder_Linux_X86_ARM_v1.0.zip

    A sample file containing the audio of a telemetry file can be found here: https://www.amsat-ea.org/app/download/13398144/URESAT-1_sample_FSK_telemetry-chessboard_packet.wav

    If URESAT-1 operates as intended, the project team plans to release a Linux program that will allow players to send their chess moves to the satellite, further enhancing the interactive experience.

    SpaceX's Transporter-8 Mission Launches a Diverse Array of Smallsat Missions

    SpaceX's Transporter-8 mission successfully lifted off from Vandenberg Space Force Base in California during its afternoon launch window on Monday, June
    12. Part of SpaceX's small satellite (smallsat) rideshare program, Transporter-8 carries dozens of small to pico-sized satellites and orbital
    test vehicles. This launch marks the 38th Falcon 9 rocket launch of 2023, showcasing the rocket's significance as the major workhorse in the space industry.

    As a rideshare launch, Transporter-8 doesn't have a primary mission but aims
    to lower costs for small spacecraft operators. The launch manifest for Transporter-8 includes an eclectic variety of missions. Among them is
    URESAT-1, a 1.5 P Pocketqube spacecraft from AMSAT-EA and the Spanish Amateur Radio Union (URE), equipped with an amateur radio payload that will attempt
    to play chess against opponents on Earth.

    Transporter-8's diverse manifest demonstrates the wide range of missions
    being pursued, from space manufacturing technology demonstration by Varda
    Space Industries to two cryptocurrency technology satellites (CRYPTO3 and MOXY-1) and a communications satellite for the Vatican (SpeiSat). This blend
    of missions highlights the growing importance and potential of small
    satellite deployments.

    With its rideshare model, SpaceX is enabling more affordable access to space for small spacecraft operators. By sharing the launch vehicle with multiple payloads, the costs are distributed among different customers, allowing them
    to realize their space ambitions at a fraction of the cost of a dedicated launch.

    The success of Transporter-8 adds to SpaceX's impressive track record, and if the company maintains its launch pace while incorporating successful Falcon Heavy rocket launches, it could be on track to achieve Elon Musk's ambitious target of 100 rocket launches by the end of 2023. SpaceX's dedication to advancing space exploration and commercial satellite deployments is evident
    in its consistent launch operations and commitment to driving innovation in
    the industry.

    European Space Agency and S5Lab Announce LEDSAT Digipeater Challenge

    The European Space Agency's (ESA) Fly Your Satellite! program in
    collaboration with S5Lab is offering a unique opportunity for radio amateurs around the world. The challenge is to establish communication through the LEDSAT CubeSat digipeater, providing a chance to win a special prize: a QSL card issued by the ESA Education Office and the LEDSAT team. Running from
    June 26 to July 30, this challenge allows radio enthusiasts to engage with space technology and showcase their communication skills.

    LEDSAT, developed by students from Sapienza University in Rome's S5Lab
    research team with support from AMSAT Italia, is an educational 1U CubeSat
    that participated in the second edition of the Fly Your Satellite! program.
    Its primary objective is to demonstrate a LED-based payload for ground-based optical tracking. The successful launch of LEDSAT on Vega flight VV19 on
    August 17, 2021, marked a significant milestone for the project. To celebrate the launch, a competition was launched, encouraging participants from around the world to record the first signs of life from the spacecraft.

    To participate in the challenge, radio amateurs are invited to send a message to the ESA Education Office ESTEC Ground Station, with the callsign PI9ESA.
    The digipeater will be activated during specific time windows, with operators stationed at the ground station to receive incoming messages. Upon successful reception of a message, the sender's callsign and contact details will be documented on a personalized QSL card, acknowledging their accomplishment.

    The LEDSAT digipeater can store and retransmit digital messages sent to the satellite, acting as a transponder for long-distance communication. Messages can be retransmitted immediately or with an optional delay of up to two days.

    LEDSAT follows a Sun-Synchronous orbit, resulting in two communication
    windows each day – around midday and midnight – where contact can be established. Participants can predict passes precisely above the ESTEC ground station or their area of residence by using their favorite pass prediction software or obtaining the latest Two-Line Elements for LEDSAT from https://celestrak.org/NORAD/elements/gp.php?CATNR=49069.

    Due to LEDSAT's monitoring and housekeeping requirements and the potential
    high demand from operators, the digipeater activation time slots will follow
    a pattern of one day ON and one day OFF, with the switch-on/off always occurring at 00:00 UTC. This schedule will begin on Monday, June 26th at
    00:00 UTC, and conclude on Sunday, July 30th at 24:00 UTC.

    While the challenge is supported by operators on a voluntary basis, efforts will be made to cover as many LEDSAT passes as possible, especially those occurring around local midday on weekdays. A detailed schedule of pass
    coverage will be published, so participants are advised to regularly check
    for updates.

    The LEDSAT digipeater uplink frequency is 435.310 MHz, the downlink frequency is 435.190 MHz, and the modulation type is GMSK using a CSP + Golay + ASM (AX100 Mode 5) protocol at 1200 baud. The LEDSAT team has prepared a software package and a user manual for connecting to the digipeater, available for download on the LEDSAT website at https://www.s5lab.space/index.php/ledsat-digipeater/.

    It is important to note that transmitting to the satellite is prohibited for those who are not licensed radio amateurs. However, non-licensed individuals can still participate in the challenge by listening to the messages
    transmitted by the ESTEC ground station. If they provide evidence of
    successful reception, including the date and time, they may also receive a customized QSL card.

    Participants are encouraged to mark their calendars, prepare their messages, and not miss the chance to connect and communicate with the LEDSAT spacecraft to receive their QSL card. Let's come together and make this event a
    memorable celebration of our shared passion for space exploration and amateur radio communication.

    For any inquiries regarding LEDSAT or the digipeater challenge, please email cubesats@esa.int.

    Changes to AMSAT-NA TLE Distribution for 16 June 2023

    Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates
    are completely adequate for most amateur satellites. Elements in the TLE bulletin files are updated daily. TLE bulletin files are updated to add or remove satellites as necessary Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/

    The following satellite has decayed from orbit and has been removed from this week's AMSAT-NA TLE distribution:

    MiTEE 1 NORAD Cat ID 47314 (decayed form orbit on 12 June 2023 per Space-Track).
