TV540 Data Copy Tool

For the TrueView 540 by CHCNAV LiDAR payload, there is no USB, so the Cycle data must be copied from the payload to your local drive using the TV540 Data Copy tool found in the Utilities group of the Sensor Tab of the ribbon. The TV540 Data Copy tool is used to retrieve data as well as format the sensor storage. Customize your TV540 carrier using the TV540 Data Copy tool Setting Carrier with TV540 Data Copy Tool.

To download data, the sensor must be connected to a workstation using the provided USB-C to USB-A cable.

Before starting with the workflow, the user will need to have installed the Sensor Extension for LP360, v2024.2.29.0, or newer. The sensor extension will be automatically downloaded the first time that the user tries to use the TV540 Data Copy tool or Import a TrueView 540 dataset.

After connecting the TV540 to the computer with the type-C cable provided, the computer will detect two disks:

• ALPHA_SYS which contains laser data, GNSS and IMU data.
• ALPHA_CAM which contains images.

Data Transfer

Choose the correct device from Module1 list, then select projects and Settings and then Finish.

The Data Copy Tool dialog will read the LiDAR type and SN on the top left corner.

The user can check project data folders on the sensor by selecting one or multiple sets of data, then it will display corresponding camera pictures, laser and GPS data within the dialog.

Note: Select one or multiple sets of data needed to copy with CTRL and Shift shortcuts.

Define an output path to store project data on your computer, then select Copy.

Note: The default path setup is on the sensor. Select the ellipsis to set data path.

Once the data has finished copying, the user will be prompted to exit the card. 

Disk Format

If the disk storage is insufficient, select the Format icon on the upper right corner to format the disk. Formatting the disk will only delete stored project data and will not delete the default parameter folder.

Note: If the memory of one of the disk is less than 10% or cannot meet storage requirements, the user will need to free disk memory prior to flights.

Note: The user should only format the disk via the Data Copy Tool. If not performed properly, Windows disk format will delete the necessary files required for the sensor to operate and will cause an error.

There are rare cases that might require Windows formatting tools. If so, reference the following article and follow the listed steps to ensure that there are no future issues with the sensor: https://support.geocue.com/tv540-sensor-formatting/

USB Exit

Once the data copy is complete, select USB Exit to eject the disks first, then disconnect the type-C cable between the TV540 sensor and PC. Failure to eject the disks may result in errors.

How to use the Data Copy tool

1. Connect the sensor to a workstation using the USB-C to USB-A cable. 
2. Open LP360.
3. Open the TV540 Data Copy tool found in the Utilities group of the Sensor Tab of the ribbon.
4. Follow the steps and save the Cycles to a local HD. 
5. Organize the Cycles (flights) in a single folder. 
6. Add the base station file (RINEX v3.x format) and the coordinates of the base station in WGS84/ITRF2014 Latitude, Longitude and Ellipsoidal height.
7. Once the data is copied over to a local hard drive, create a new project by opening the Raw Mission Import Wizard and select TrueView/Microdrones as the sensor.
