Session button
To safely end a logging session, press and hold the Session button (≈2 seconds) until the white, green, and red LEDs
turn solid. Once you have ended a session, you may start a new session by pressing the Session button once.
Control button
This button controls triggering according to the settings in the CONFIG file.
Retrieve System Information
To obtain information about the GeoSnap unit (carrier board serial number, firmware version, & bootloader
version), press and hold the Session and Control buttons while powering on the unit. Once the white, green, and
red LEDs turn solid, release the buttons and unplug power from the GeoSnap. Remove the microSD card, then use
a computer to read the system_info.txt file that was written to the microSD card’s root directory.
POWERING THE GEOSNAP SYSTEM
Battery Information
Two Turnigy 9XR 2200mAh 11.1V Li-Po batteries are included for powering the system. These batteries have built-
in undervoltage protection, which means that power will be cut from the output leads if any cell drops below 3.0V
(thus preventing damage to the battery). The advantage of using these batteries to power the GeoSnap (as
opposed to using power from the drone) is that the GeoSnap can keep logging and maintain GPS lock, even if the
drone’s batteries needs to be swapped when mapping large areas.
Checking Battery Voltage
You can check the voltage of the entire battery and it’s individual cells by plugging in the battery’s balance plug
into the connector labeled “3 Cells” on the included DC-4S charger/voltage checker (you can even do this while the
battery is powering the GeoSnap as depicted below).
A full battery has a total voltage of 12.6V –12.5V. The battery is practically depleted once it has reached 10V. A
fully charged battery can run the GeoSnap for about 8 hours.

Field of View GeoSnap Basic Manual 7
Battery Charging
1) Plug in the AC adapter into the wall.
2) Plug in the barrel power plug from the AC adapter into the DC-4S charger/voltage checker. Check to make
sure that 3 dashes are displayed before plugging in the battery (this indicates that there is indeed power
getting to the charger and that it isn’t just operating as a voltage checker).
3) Insert the balance plug of the battery into the connector labeled “3 Cells”. The charger will display the
overall voltage battery and the voltage of each cell as it charges. Charging a fully depleted battery takes
about 2 hours and 30 minutes.
4) Once the battery is fully charged, the charger will display “FUL” and begin to beep. At this point you
should disconnect the battery and unplug the AC adapter from the wall.

SYSTEM OPERATION
Required Equipment
Be sure to have a Windows laptop or desktop available with the ability to read a microSD card and with the Google
Chrome browser installed (necessary for viewing/editing the CONFIG.html file).
Image Number Reset
The GeoSnap does not get the actual image names from the camera. For each new session, the first event
recorded will always be labeled as event_00001. It is recommended to set the camera’s file numbering setting to
“Reset”(using the camera’s menu). Then, before starting a new GeoSnap logging session, clear all images off the
camera’s SD card. This will cause the first image taken to be named DSC00001.JPG (or something similar depending
on which camera you have). By having the image numbering and the event numbering both start at 1, it is easier to
quickly ensure that there is an event for each image captured after your flight.
Operation Procedure:
1. Make sure there is an appropriate microSD card in the GeoSnap and the CONFIG file settings are correct
for your mission (see the GeoSnap Basic Files section in the manual to learn more about the CONFIG file).
2. Plug in the power cable. The blue Power LED will illuminate and the white, green, and red LEDs will cycle
while the system is booting up.
3. After the system has booted, the green GNSS LED will start a single flash sequence indicating that the
system is searching for satellites.
4. If the Trigger Mode is set to “Time” and the Trigger Control is set to “Auto-start”, the first trigger
command will be sent as soon as the system has completed its boot up sequence.
5. If the GeoSnap Basic’s antenna has an unobstructed view of the sky, then the green GNSS LED should
begin to double flash in less than 30 seconds (indicating that it is tracking at least one satellite).
6. If the GeoSnap Basic’s antenna has an unobstructed view of the sky, then the green GNSS LED should
begin to triple flash within 1 minute (indicating that it is has a 3D fix).
7. If distance or overlap trigger modes are set to “Auto-start”, the first trigger command will automatically
be sent immediately after the estimated accuracy reaches 3 meters or less OR 1 minute after the system
first acquired a 3D fix (whichever comes first).
8. If the GeoSnap Basic’s antenna has an unobstructed view of the sky, you will observe the green GNSS LED
advance to shining solid within 1-2 minutes (indicating that it is has a 3D fix with accuracy estimate of 3
meters or less). This would typically be the time to start your flight. The estimated accuracy of the
GeoSnap Basic is 2-3 meters.
9. Once you are done with your session, safely stop logging by pressing and holding the white Session button
(≈2 seconds) until the white, green, and red LEDs turn solid. You may now take one of the following
actions:
a. Press the Session button when you are ready to start a new session. If the antenna maintained a
clear view of the sky, the GNSS status should be the same as when the previous session was
stopped.
b. Remove the microSD card and insert it into your computer to check the events log, copy session
folders to your computer, and/or change settings in the CONFIG file. When finished, safely eject
the microSD card from your computer and re-insert it into the GeoSnap (which is still powered
on). Press the Session button when you are ready to start a new session.
c. Connect the GeoSnap to a Windows PC using a microUSB cable. The GeoSnap will configure itself
as a mass storage device and act as a USB drive. You can check the events log, copy session
folders to your computer, and/or change settings in the CONFIG file. When finished, safely eject

Field of View GeoSnap Basic Manual 11
the USB drive from your computer. Press the Session button when you are ready to start a new
session.
d. Power down the GeoSnap and save a copy of the session folder(s) to your computer.
10. The events file contains the standard accuracy geotags and just needs to be associated to the images
using the Geotags Tool. Check out this video on how to use the Geotags tool. Once that quick step is
complete, the geotags are ready to be imported directly into a stitching software.
GEOSNAP BASIC FILES
FILE/FOLDER STRUCTURE
The GeoSnap Basic microSD card file/folder structure is outlined below:
•Configuration file (CONFIG.html)
•Session folder with valid GNSS data (yyyy-mm-dd_hhmmss)
oEvent file (yyyy-mm-dd_hhmmss.txt)
oCopy of the CONFIG file used for the session (yyyy-mm-dd_hhmmss_config_snapshot.html)
oGeotags application file (Geotags Tool v4.6.exe)
•Session folder without any valid GNSS data (1980-01-06_000001)
oEvent log (1980-01-06_000001.txt)
oCopy of the CONFIG file used for the session (1980-01-06_000001_config_snapshot.html)
oGeotags application file (Geotags Tool v4.6.exe)
CONFIGURATION FILE
The CONFIG file is an HTML file used to configure the settings of the GeoSnap Basic. Each time the GeoSnap boots
or starts a new session, it searches the root directory of the microSD card for the CONFIG file and reads the
settings. If a CONFIG file is not present, the GeoSnap will generate a default CONFIG file (in this case, the blue and
white LEDs will flash/beep for 10 seconds at boot-up letting you know that you should review/edit the settings).
It is highly recommended to open and save the CONFIG file using the Google Chrome web browser. Note that an
internet connection is not required to view and edit the CONFIG file. The interactive interface consists of a variety
of fields and drop-down menus that you can use to select your trigger mode, trigger parameters, and to record the
camera-to-antenna offset for your drone. Once you are done editing the settings, follow these instructions:
Saving Instructions:
1. Right click on an empty spot inside your browser window and select "Save as..."
2. Leave the file name as "CONFIG", but make sure the save as type is "Webpage, Complete"
3. Navigate to the root directory of your microSD card and then press "Save"
4. If there is already a CONFIG file present, a window will appear asking if you want to replace it. Press "Yes"
5. Safely eject the microSD card from your computer and proceed to operate the GeoSnap system

Trigger Mode
Trigger Mode
Description
Time mode sets the system to trigger on a set time interval in
seconds. Min value is 0.3 s, max value is 10,000 s.
[Default setting: 2 seconds]
2D Distance mode sets the system to trigger at a set
horizontal distance interval in meters. Min value is 0 m, max
value is 10,000 m.
[Default setting: 10 m]
3D Distance mode sets the system to trigger at a 3D distance
interval in meters (combined horizontal and
vertical distance traveled). Min value is 0 m, max value is
10,000 m.
[Default setting: 10 m]
Overlap mode sets the system to trigger at specific interval to
maintain a desired frontal overlap percentage between
images. This requires the input of various values including
the desired overlap percentage, the Above Ground Level
altitude the mission will be flown at, the focal length your
camera’s lens, and the camera sensor dimensions. Only the
Height value of the sensor dimension is used in the overlap
calculation since most cameras are mounted in the
“landscape” orientation relative to the direction of flight. If
your camera is mounted in the “portrait” orientation, then
simply type in larger dimension of the sensor in the Height
field.
[Default settings: Shown left]
Single mode sets the system to trigger one image per trigger
control input sent (see the next section).

Description
Auto-start mode is available for Time, 2D
Distance, 3D Distance, and Overlap
triggering modes. When the Trigger Mode is
set to Time, the first trigger command will
be sent once the system is done booting.
When the Trigger Mode is set to 2D
Distance, 3D Distance, or Overlap, the first
trigger command will automatically be sent
immediately after the estimated accuracy
reaches 3 meters or less OR 1 minute after
the system first acquired a 3D fix
(whichever comes first).
Press and hold the Control button on the
GeoSnap to start triggering, an audible beep
will sound to confirm the triggering
sequence started. Press and hold the
Control button on the GeoSnap to stop
triggering, an audible double beep will
sound to confirm the triggering sequence
has been stopped.
A PWM input on the white wire of the
PWM/GPIO-input-cable can be used to
control triggering. Refer to the section titled
“PWM Behavior” for more information.
A GPIO signal on the white wire of the
PWM/GPIO-input-cable can be used to
control triggering. Refer to the section titled
“GPIO Behavior” for more information.

Field of View GeoSnap Basic Manual 14
PWM Behavior
By selecting PWM input in the Trigger Control field, a second drop down will appear called Behavior. This
dropdown allows you to specify which transitions (low-to-high, high-to-low etc.) will trigger the GeoSnap. The
GeoSnap will interpret any pulse widths shorter than 1700 microseconds as a “low”, and any pulse widths longer
than 1700 microseconds as a “high”.
Behavior
Description
If the GeoSnap is not triggering,
then a transition from a low pulse
width to a high pulse width will start
triggering. If the GeoSnap is already
triggering, then a transition from a
low pulse width to a high pulse
width will stop triggering.
If the GeoSnap is not triggering,
then a transition from a high pulse
width to a low pulse width will start
triggering. If the GeoSnap is already
triggering, then a transition from a
high pulse width to a low pulse
width will stop triggering.
The GeoSnap will trigger while the
pulse width remains high. As soon
as the pulse width goes low, the
GeoSnap will stop triggering.
The GeoSnap will trigger while the
pulse width remains low. As soon as
the pulse width goes high, the
GeoSnap will stop triggering.

Field of View GeoSnap Basic Manual 15
GPIO Behavior
By selecting GPIO input in the Trigger Control field, a second drop down will appear called Behavior. This
dropdown allows you to specify which transitions (rising edge, falling edge) will trigger the GeoSnap. A “low”GPIO
signal is defined as 0-1.0V whereas a “high” GPIO signal is defined as 2.3-5V. Rising edge refers to the transition
from a low GPIO signal to a high GPIO signal, whereas falling edge refers to the transition from a high GPIO signal
to a low GPIO signal. The signal must remain at high or low status for at least 50 milliseconds for the GeoSnap to
properly interpret the GPIO signal.
Behavior
Description
If the GeoSnap is not triggering, then
a transition from a low GPIO signal to
a high GPIO signal will start
triggering. If the GeoSnap is already
triggering, then a transition from a
low GPIO signal to a high GPIO signal
will stop triggering.
If the GeoSnap is not triggering, then
a transition from a high GPIO signal
to a low GPIO signal will start
triggering. If the GeoSnap is already
triggering, then a transition from a
high GPIO signal to a low GPIO signal
will stop triggering.
The GeoSnap will trigger while the
GPIO signal remains high. As soon as
the GPIO signal goes low, the
GeoSnap will stop triggering.
The GeoSnap will trigger while the
GPIO signal remains low. As soon as
the GPIO signal goes high, the
GeoSnap will stop triggering.

Offsets
Camera to Antenna Offsets
Description
Type in the X, Y, and Z offsets from the camera to the
antenna. More information on how to do this correctly is
below.
This diagram show how the X, Y, and Z axis aligned to an airframe. It also shows that an offset may be positive or
negative depending on where the antenna is mounted relative to the camera.
The simple, fast way to determine the offsets when using the GeoSnap is to follow these steps:
1) Use a tape measure or ruler to estimate the X and Y offset from the lens centerline to the center of the
antenna. A rough estimate (+/- 2cm) is sufficient since any error in the X and Y offset measurements tend
to get averaged to near 0 when performing grid mapping missions. Keep in mind that the all the offsets
need to be entered into the CONFIG file in meters.
2) The Z offset is more critical to measure accurately. Add the following distances to get the Z offset value
when using the GeoSnap
dZ = antenna L1 phase center-to-bottom of antenna + bottom of antenna-to-focal plane mark( o ) of the
camera + lens focal length
For the grey helical antenna that is included with most GeoSnap kits, the distance from the antenna L1
phase center to the bottom of the antenna is 0.0318 meters. The resulting equation would be:
dZ = 0.0318 meters + bottom of antenna-to-focal plane mark( o ) of the camera + lens focal length

Settings Reviewed
Settings Reviewed
Description
If “Yes, I have reviewed these
settings” is selected, blue and white
LED will no longer beep for 10sec
after booting. The objective of this
feature is to help prevent the
situation where you accidently fly a
mission with the wrong settings.

EVENTS FILE
The yyyy-mm-dd_hhmmss.txt Events File is a comma delimited text file that contains a log of the uncorrected
position data and other GNSS information for each event. You can view the file contents by opening it with a text
editor, such as Notepad.
The first line in the events file displays parameters such as system serial numbers, firmware version, receiver
information, and the X, Y, and Z offset values that were entered in the CONFIG file.

CONFIGURATION FILE SNAPSHOT
The yyyy-mm-dd_hhmmss_config_snapshot.html file is an HTML file that contains the parameters used for the
session. While the original CONFIG file is in the root directory and is used to change GeoSnap settings, the CONFIG
file snapshot cannot be changed and is found in every session folder that gets generated. Note that an internet
connection is not required to view the CONFIG file snapshot.
GEOTAGS TOOL
The Geotags Tool is a simple application that gets written to every session folder. It has three main functions:
1. It creates a Pix4D and Agisoft compatible “geotags file” using the position data from the events file and
the image name/numbering scheme you specify.
2. It creates a KML file that allows you to quickly see your geotags in 3D using Google Earth.
3. It can embed geotags and their accuracy estimates into the metadata (Exif and XMP) of your images.
The following are two different step-by-step guides on how to use the Geotags Tool. The first focuses on how to
create the geotags file and KML file only, while the second focuses on how to also embed coordinates into the
metadata of your images. A video of the process can also be found at
https://www.youtube.com/watch?v=I9JPxTwCBio.

Field of View GeoSnap Basic Manual 19
Generate an uncorrected Geotags File & KML File
1. Launch the Geotags Tool by double clicking the Geotags Tool application in the session folder with your
mission data.
2. The application automatically finds the events file in the folder it was launched from and populates it in
the top bar (you also have the option to browse for a different events file). Upon finding a valid events
file, the application will display the Event Range and Event Count.

Field of View GeoSnap Basic Manual 20
3. Use the Image Name pane to specify the image name/number that corresponds to event_00001. You can
manually edit the Prefix, Number, and Suffix fields or you can drag and drop the image file that
corresponds to event_00001 into this pane (the Geotags Tool will then automatically parse the Prefix,
Number, and Suffix). The fields are pre-populated for a Sony image named “DSC00001.JPG” to
demonstrate the parts of a file name that constitute the Prefix, Number, and Suffix. If you manually type-
in the image Number, be sure to include any neccessary leading zeros.
4. If the X, Y, and Z offsets are different than what got automatically imported from your events file, then
you can edit them in the Offsets pane.
