    📡 ISS APRS Pass Report

    Frequency: 145.825 MHz FM (1200 baud AFSK)
    Path: ARISS
    Filter: High-elevation passes (>60°) during 8 AM – 10 PM

    About ISS APRS: The International Space Station operates an APRS digipeater on 145.825 MHz.
    High-elevation passes (>60°) provide the best line-of-sight and strongest signals for successful packet radio contacts
    with handheld radios and modest antennas.
    Equipment Options:

    • Radios with Built-in APRS: Most Yaesu HTs (FT1D, FT2D, FT3D, FT5D), some Kenwood HTs (TH-D72A, TH-D74A, TH-D75A),
      Baofeng UV-PRO, and other newer radios have internal APRS capability – no external TNC needed!
    • Traditional Setup: Any VHF transceiver + TNC or sound card interface for 1200 baud AFSK
    • Software: APRS client (Xastir, YAAC, APRSDroid, etc.) or use built-in radio APRS
    • Antenna: Simple vertical works well for high passes; better results with directional
    • Path: Use ARISS for digipeating (not WIDE1-1 or other terrestrial paths)

    11:43 AM – 11:54 AM 78° max
    Start: 11:43 AM at 228° (SW) – ISS rises above horizon
    Highest Point: 11:49 AM at 132° (SE), 78° elevation
    End: 11:54 AM at 54° (NE) – ISS sets below horizon
    Duration: 10 minutes 45 seconds
    Frequency: 145.825 MHz FM (1200 baud AFSK)
    Path: Use ARISS for digipeating

    6:14 PM – 6:24 PM 85° max
    Start: 6:14 PM at 308° (NW) – ISS rises above horizon
    Highest Point: 6:19 PM at 25° (NNE), 85° elevation
    End: 6:24 PM at 128° (SE) – ISS sets below horizon
    Duration: 10 minutes 45 seconds
    Frequency: 145.825 MHz FM (1200 baud AFSK)
    Path: Use ARISS for digipeating

    Wednesday, April 01, 2026

    12:31 PM – 12:41 PM 61° max
    Start: 12:31 PM at 239° (WSW) – ISS rises above horizon
    Highest Point: 12:36 PM at 327° (NNW), 61° elevation
    End: 12:41 PM at 50° (NE) – ISS sets below horizon
    Duration: 10 minutes 45 seconds
    Frequency: 145.825 MHz FM (1200 baud AFSK)
    Path: Use ARISS for digipeating

    Operating Tips:

    • Start transmitting when ISS is 10-15° above horizon
    • High-elevation passes (>60°) provide 4-6 minute windows for successful contacts
    • Use short position beacons and messages – packet collisions are common
    • Monitor 145.825 MHz to see your packets digipeated back
    • Check ARISS status before operating
