Operation Guide

This section provides a general operational user guide, following the recommended operation procedure. Use this guide together with the LiAcquire User Guide.

Mission Preparation and Planning

Mission planning is critical to successful LiAir data collection. Operators should attempt to complete the following preparations prior to take-off:

§ study the project site and identify potential hazards within the survey area

§ check weather and GPS signal forecasts for survey area for the duration of the intended data collection period

§ verify that equipment is not damaged and in good condition

§ brief support staff on plans for data collection and any potential hazards

It is highly recommended that operators create custom LiAir mission check list and establish standardized workflow protocols.

It is also recommended, when possible, to investigate the survey area and construct mission flight plans prior to arriving at the project area. This will speed up data collection and make operators more aware of surrounding hazards.

Site Inspection

After arriving at a project site, operators should take time to inspect the site thoroughly. Operators must identify all potential hazards found within the project area. Special attention should be paid to terrain variation and elevation changes within the project area. Tall objects, such as powerlines, trees, and structures that may pose danger to the flight must be located and accounted for during flight planning. Extra precaution should be taken when operating LiAir in new places and unfamiliar situations.

During the site inspection, operators should locate a relatively open area, free of hazards, which is flat enough to designate as the point for UAV take-off and landing. This will be referred to a Home Location. Mark the location with a high-visibility landing pad if necessary.

Set up Base Station

Set up the Base Station as soon site inspection is complete and Home Location has been identified. Once Base Station data recording has started, it is necessary to not stop data collection or move the GNSS antenna for the duration of the LiAir mission.

Special Notes

Here are some special notes to pay attention while operating LiAir. GVI has compiled these notes based on past experience and feedback from customers. The following points out details that seem small or insignificant but can, however, lead to issues that may be difficult or impossible to rectify post mission if left unchecked.

Pre-fight

§ Make sure the Lens Cap is removed from the camera before mission.

§ Make sure the camera’s SD card is NOT set to Write-Protected or Locked.

§ It’s best to delete all existing images from the camera’s SD card before a new mission. But be sure NOT to delete the folders or format the card.

§ Always double check all antenna and cable connections are secure.

Operation

§ System power on/off sequence: UAV ON -> LiAir On -> LiAir Off -> UAV Off .

§ System safe operating temperature: - 10℃ to + 40℃.

§ System max wind resistance: 8m/s.

§ Before mission, make sure the internal storage unit has at least 6GB of space available.

§ When the system starts to collect data successfully, you should see in LiAcquire the Synchro Status turn green, and point cloud data displayed in Viewer.

§ Before lifting off and after landing the UAV, leave the system on the ground, UNDSTURBED, for at least 5 minutes.

§ Do not touch or move the GPS Base Station Antenna once it starts logging data. Base Station should start recording data well ahead of the mission and continue to record data until all mission(s) are completed.

§ Stop data logging first before powering off the Base Station.

About the Instruments

§ The LiAir system integrates a number of high-precision instruments. Please handle with care.

§ Avoid direct impact to the system. Always store all items properly in the protective case before transporting. Do not move or transport the system unprotected.

§ Do NOT scratch the Laser Scanner Lens.
