  • Pitch Vernier

    Setting pitch by sliding the battery fore/aft: battpos/setonce/servo modes, the m_battpos sensors, blue Loctite on the mounting screw, and troubleshooting a loose or stuck pitch battery.

  • Freewave

    The 900 MHz RF modem: master/slave setup, Freewave vs. Iridium, console power saving, and interference troubleshooting.

    Freewave

  • Iridium

    The satellite link: RUDICS vs. dial-up, the surface comms sequence, SIM cards and service, testing with callback, and data transfer.

    Iridium

  • Argos

    The one-way 401 MHz position beacon: how c_argos_on activates it at the surface, its ~90 s transmit cadence as a noise source, service and IDs, message decoding, and testing.

  • Fin / Digifin

    The self-calibrating tail fin: steering, m_digifin_status bits, leak detect, rudder replacement, and field workarounds for a stuck or noisy fin.

    Fin / Digifin

  • Compass / Attitude Sensor

    The True North attitude sensor: heading/pitch/roll, magnetic variation, shore calibration with RevolutionTest, the in-situ at-sea cal, the post-cal compass check, and diagnosing heading spirals.

    Compass / Attitude Sensor

  • Thruster

    The optional 10-Watt tail thruster: assisted yos, drift-at-depth, and lens penetration; the four control modes; the energy penalty; in-air checkout, post-deployment care, and troubleshooting.

    Thruster

  • O-Rings

    Hull and component seals: G2 single-seal vs G3 double-seal part numbers, approved lubricants and the dry-out problem, inspection and replacement, the sealing-surface scratch debate, and vacuum/leak testing.
