Observatory Vibration Monitoring System. Uses accelerometers to collect fast measurements from the telescope. It's primary used for LBTI to measure and correct telescope vibrations. It's also used by engineering to monitor telescope vibrations.

Where it runs

  • ovms-uei - OVMS PowerDNA cube. PowerPC running modified Linux Kernel. ssh in allowed. Located at LLTH (Lower Left Tree House), has 12 I/O boards for data collection.
  • ovms - PC with OVMS interface (only visible from LBT network/VPN).

How it runs

  • accelerometer collect data, feed them trough I/IO into PowerDNA cube
  • PowerDNA runs in its FPGA data collection
  • Data are transmitted to PowerDNA main CPU
  • Data are sent from PowerDNA as UDP broadcast
  • Clients collect data from UDP broadcast and do what the need to do, primarily
    • LBTO Telemetry client (records hdf5)
    • OVMS+IF/piston, used by LBTI
    • OVMS+AO/TT - currently (Sep, 2018) under development by Notre Dame
