About GeoCue Group, Inc.
GeoCue Group was founded in 2003 by a group of engineers with extensive experience in developing
hardware and software solutions for primary remote-sensed data acquisition. Our initial products were
aimed at reducing schedule and cost risk in geospatial production workflows by providing
organizational, productivity and data management tools for base geospatial data production. These
tools have been realized as the GeoCue product family. Today GeoCue workflow management tools are
used by a majority of North American geospatial production shops. In 2005, GeoCue began selling and
supporting Terrasolid tools for kinematic LIDAR data production. This was followed in 2009 by our
acquisition of QCoherent Software LLC, the creator of the point cloud exploitation toolset, LP360.
Today GeoCue is the largest supplier of kinematic LIDAR processing tools in North America and LP360
is the world’s most widely used tool for exploiting point cloud data. In 2014, GeoCue Group started a
division focused on using small Unmanned Aerial Systems for high accuracy mapping. Leveraging our
expertise in production, risk reduction, and point cloud processing tools, we are continuing to bring new
services and products to market to provide surveyors and other geomatics professionals exciting tools
for geospatial data extraction using low cost drones including Loki, our plug-and-play PPK direct
positioning system, and now our new True View LIDAR/Imagery fusion sensors. To learn more, visit

About True View® 615/620
The True View® 615/620 is GeoCue’s second generation LIDAR/camera fusion platform designed from
the ground up to generate high accuracy 3D colorized LIDAR point clouds using the new Riegl miniVUX-
2UAV. Featuring dual GeoCue Mapping Cameras, a Riegl miniVUX-2UAV laser scanner and Applanix
Position and Orientation System (POS), the result is a true 3D high accuracy imaging sensor (3DiS).
With its wide 120° fused field of view, the True View 615/620 provides high accuracy 3D color mapping
with excellent vegetation penetration and wire detection in a payload package of 3-3.5 kg.
A True View Cycle
All True View sensors write their various data streams to a standard file folder structure called a “Cycle.”
The original meaning of cycle was an on/off cycle of the sensor. It is possible to have multiple collections
(flights, in the case of a drone) in a single Cycle, so it is not necessarily correct to think of cycle as being
synonymous with a flight.

True View 615/620 Hardware Integration Kit
The True View 615/620 was designed to be used with the GeoCue’s True View Integration kit, which
includes an antenna mounting plate and a DJI Ronin gimbal mount with vibration dampeners. If your
True View 615/620 and M600 were purchased through GeoCue, the antenna mounting plate and Ronin
mount were installed by a GeoCue technician. If you purchased your M600 from a third party, you will
need to install these components before using your True View system. The following steps explain how
to install your True View integration kit.
Installing the Top Plate and Controller Box
1. To install the top plate and controller box you will need the following components:
a. Top plate. (Figure 1)

True View Battery
The True View 3DIS is powered by its own 3200 mAh removable lithium-ion battery. The True View
power system was designed to be standalone and does not use power from the aircraft’s power system.
This ensures that True View does not interfere with critical flight functions. You can expect to get
about 90 minutes from each battery under normal conditions, but cold temperatures can significantly
reduce battery life.
Figure 24 –Removeable battery
The True View 3DIS comes with two RRC2054 batteries (Figure 24), which have built-in charge status
indicators, and a charging station.

True View USB Mass Storage (UMS)
The True View UMS (USB mass storage) device is the media attached to the True View sensor on which
A True View Cycle will be written during flight operations and system wind-down.
Figure 25 - UMS
The UMS should meet the following requirements to be used on the system.
1. USB-C connection (USB 3.1)
2. FAT32 format for firmware pre v2.0.3, or NTFS after updating firmware to v2.0.3 or later
3. 114 GB minimum capacity
4. Need “SystemConfiguration.json” and “CoreConfiguration.json” files on the drive during
operation.
System Configuration File (SCF)
The System Configuration file (SCF), SystemConfiguration.json, must reside on the True View USB
Mass Storage and is copied into the Cycle\System folder upon creation of each Cycle. The SCF contains
information on the calibration parameters of all components for each True View system and is used by
True View EVO to process True View data. The latest calibration file for each sensor is stored on the
True View Reckon portal.
Core Configuration File (CCF)
True View System settings are stored internally to the system, but can be changed by modifying the
CoreConfiguration.json file on the UMS. The system identifies if the file has been modified, then
operates accordingly. Features may be turned on or off by using a true or false Boolean in the Core
Configuration file. Other fields can be configured with a numeric value, such as the Battery Status
Percentage or Proximity Mode Distance.
Note: It is recommended to open and modify the Core Configuration file with Notepad++.
The following sections describe the most common sections of the Core Configuration file that a user
may wish to modify.

CCFSection6 –POS
Figure 26 - Core Configuration POS
This section is applicable for CCU firmware v2.1.7 and later.
If the “GNSS_lever_arm_change” is true, the True View is configured to update the lever arms in the
APX unit to the values ascribed in this section. A user should only modify “GNSS_lever_arm_x”,
“GNSS_lever_arm_y”, or “GNSS_lever_arm_z” if they are not using the system on a drone integrated
by GeoCue. Updating the lever arms using this section of the Core Configuration file replaces the need
to log into the APX-15 to update those values. See Measuring GNSS Lever Arm Offsets in this guide.
The values shown in Figure 26 are the standard True View 615/620 mounted on an M600 with the GNSS
antenna secured integral with the control box with an LED readout display.
CCFSection8 –Camera
Figure 27 - Core Configuration –Camera
This section is applicable for CCU firmware v2.1.1 and later.
Set “CameraOperate” to false if you do not wish to use the cameras for a mission. For example, a late
evening flight.

True View 615/620 Hardware User Guide
19 True View 615/620 Hardware User Guide 12/21/2020
If the “CameraFileTransferWindDown” is true, the True View is configured to operate in Standard mode
and the images will get transferred to the UMS drive during the wind-down sequence. This field is true
by default and is recommended not to be changed.
If it is false, the True View is configured to operate in Extended mode and the images will not get
transferred during wind-down and they will have to be manually downloaded from each camera SD
card and placed in the Camera 1 and Camera 2 folders in the cycle folder.
The image transfer process takes about 5 minutes for a 15 minutes flight. For aircraft that can fly for
extended periods of time (greater than 30 minutes of flight), it is recommended to set this field to false,
and transfer the images manually.
CCFSection11 –Configuration Laser
Figure 28 - Core Configuration –Laser
This section is applicable for CCU firmware v2.1.1 and later.
Set “LIDAROperate” to false if you do not wish to use the laser scanner for a mission. For example, an
imagery only mission.
LIDARTimeOut is used to signal via a red SYS light that the laser scanner did not properly start within
this time frame. We recommend 30 seconds as the default.

Laser Model must be 1 for a True View 615/620.
The FrameRate should be left as 10 and not be changed.
The FOVCenter is set to 90°by default to indicate the center of the laser field of view is pointing
downward at nadir and should not be changed.
The FOVWidth controls the active radial scan zone of the laser scanner. Normally set at 120° to only
record data from the laser scanner between +/- 60° of nadir (FOVCenter set at 90°).
The Pulse Repetition rate will be 100 kHz if set to 0, and 200 kHz if set to 1.
The BaudRate should be left as 3 and not be changed.
CCFSection15 –Battery
Figure 29 - Core Configuration - Battery
This section is applicable for CCU firmware v1.2.3 and later.
The Battery Status Light (BAT) on the True View controller box will be colored based on the percentage
entered in the “LowBatteryPercent” and “CriticalBatteryPercent” fields. The BAT light will be green if
the battery is above the “LowBatteryPercent” value. It is 50 by default. The BAT light will be yellow if
the battery is between the “LowBatteryPercent” and the “CriticalBatteryPercent” value. The BAT light
will be red if it is below the “CriticalBatteryPercent” value. It is 30 by default.
