Recon Acquisition

If you are using a Recon, the Recon Quick Start Guides include best practices which are helpful to review.

General Best Practices:

• Use only the supplied USB stick. The RECON hardware requires USB sticks with minimum write transfer speed, many other USB sticks can not write data fast enough, causing data corruption.

• Ensure you always remove the USB stick safely from your computer, and re-format it regularly using the RECON’s web UI.

• To avoid problems in postprocessing, ensure IMU-to-antenna offsets and IMU rotation are correct before acquisition.

• Wait for the camera to trigger two/three times and appear in the GUI before starting 'Data recording'.

• At the very beginning and end of acquisition, leave the system acquiring data while static for at least 30 seconds.

• Ensure good GNSS reception and free sky during kinematic alignment and figure 8 maneuvers.

• Capture at least GPS+GLONASS data from a close-by reference station at 1-20 Hz, covering all of the rover’s acquisition. There’s no need to stream data from reference station to RECON during flight.

• The “Field of View” setting merely saves the given values as a processing preset, all data is still recorded with any FoV setting.

• If using SpatialExplorer, replay data to ensure LiDAR and camera coverage is sufficient before leaving.

SLAM Best Practices

• Processing is only available when using SpatialExplorer (not in LiDARMill).

Mobile Best Practices

• Use the longer legs on the mobile mount if your vehicle’s trunk is slanted and you want to bring the unit past the roof’s edge.

• Use a camera interval of 120s (max) to take as few photos as possible, as they won’t be used anyway.
