If geofencing is used, you must provide a separate file named "geo_fence.csv" in the root
directory of the SD-card which defines the flight area limits. The CSV-file must contain the
following three columns, each polygon corner in one line:
1.
latitude in degrees
2.
longitude in degrees
3.
upper altitude limit in meters above ground (takeoff position)
Although an altitude limit is specified for each polygon corner, currently only the altitude limit
of the last corner is used for the whole polygon area. It is recommended to use the same value
for all corners. Lines beginning with a hash symbol ('#') are ignored and can be used as
comments.
Here is an example:
geo_fence.csv
# Geofence Example
#lat [deg], long [deg], altitude [m]
47.0775, 15.4435, 60
47.0763, 15.4414, 60
47.0760, 15.4429, 60
47.0749, 15.4427, 60
47.0752, 15.4457, 60
The UAV may fly within the polygon up to a
height of 60 m above ground.
Alternatively, you can use the web-based tool on the website of Drone Rescue Systems GmbH
(see Figure 1) to configure the geofence. To access this tool you must register on our website
. After drawing the geofence on the map you can download the
file called "geo_fence.csv" and place it in the root directory of the micro SD card. The "Above
Ground Level" (AGL) altitude is the height limit of the geofence corridor. The DRS geofence
software supports up to 50 GPS points.
