Pre-Recording Checklist

☐ Mounting the Payload

• Mount the RESEPI unit securely using the vehicle mount adapter.
  • Ensure it is fully seated in the mount and locked into place to prevent vibration or slippage during travel.
  • Mount orientation should be known and stable.
  • Avoid loose brackets or makeshift adapters.

☐ Connect GNSS Antennas

• Connect all GNSS antennas to their correct ports.
  • If using a dual antenna setup, confirm correct configuration of primary and secondary.
  • Verify each antenna has a clear sky view.

☐ Base Station Setup (if applicable)

• Place the base station in an open area with clear sky view.
• It should record all available GNSS constellations (GPS, GLONASS, Galileo, BeiDou, QZSS, Navic).
• Confirm that it records in a PCMasterPro-compatible format.
• If using a public base station, ensure it is within 40 km of the flight area (preferably closer).
• Important: Ensure correct PPK or RTK configurations.
  • Methods are comparable to PPK Step-by-Step and RTK Step-by-Step.

☐ Power Connection

• Connect RESEPI to power via one of the following:
  
  • XT60
  • Skyport/Other
  • Binder Connector
  • Ethernet (GEN-II only)
• Ensure power supply is 9–36VDC (up to 45V max) with 24–28W available.

☐ Web Interface Access

• Connect to the RESEPI’s Wi-Fi.
  • SSID is printed on the unit label.
  • Password: LidarAndINS
  • Access the Web GUI at 192.168.12.1 using a laptop or mobile device.

☐ Data Management

• Offload all data and flights from the USB drive and/or SSD to ensure adequate space.

☐ USB / SSD Storage Check

• Use only the provided RESEPI-certified USB drive.
• Confirm that the USB is securely inserted into a supported port.
• Avoid using ports reserved for other onboard components (e.g., camera).

☐ Firmware Check

• Ensure the RESEPI is running the latest firmware version.
• You can find the firmware version in the top right corner of the GUI.

☐ Enable Secondary Antenna Logging (if applicable)

• Enable recording from the secondary GNSS antenna.
  • Navigate to: Settings > INS Service
  • Toggle “Record Secondary Antenna data” → On
  • Click Save.
  • Go to the Status page to confirm the secondary antenna is detected and observing satellites.

☐ Vehicle to IMU Rotation

• Go to Settings > Geometry > Vehicle to IMU Rotation.
• Ensure the rotation offsets reflect the RESEPI’s mounted orientation on the vehicle.
• Incorrect values can likely cause post-processing alignment errors.
• Click Save after confirming or adjusting the values.

☐ Antenna Lever Arm Offsets (REQUIRED)

• Go to Settings > Geometry > IMU to Antenna Offset.
• Enter the accurate lever arm values (X, Y, Z) in meters.

☐ GNSS Time Fix (REQUIRED)

• Connect the GNSS antenna to RESEPI securely.
• Power the unit outdoors in a GNSS-visible area before flight.
• In the GUI, confirm the INS status shows:
  • Current date and time
  • Message: “Ready to log”
    • Do not begin data capture without this message.

☐ Camera Trigger Configuration (Optional)

• Set the trigger interval for the onboard camera, if used.
• Adjust the trigger period based on planned speed:
  • Example: 5 m/s → 5 seconds
  • Faster speeds → shorter intervals (e.g., 10 m/s → 2.5 seconds)
    • Avoid high trigger rates at slow speeds to prevent blurry or redundant images.
    • Confirm trigger settings are applied via the GUI.

☐ Final System Check

• Ensure all cables are secure (power, antenna, USB, trigger, etc.).
• Ensure RESEPI payload is secure on the respective mobile mount.
• Confirm that the LiDAR sensor is unobstructed by props or mounting hardware.
• Recheck USB/SSD/RTK modem status in the GUI.

You’re now ready to begin MMS scanning with RESEPI.
