DLS 2 with Aircraft GPS
For more control, advanced users can communicate with Altum by HTTP (Ethernet, Wi-Fi) or
serial (MAVLink) using the MicaSense APIs (Application Programming Interfaces). The APIs can
be used in lieu of the DLS 2 GPS to provide the sensor with a position and attitude data (from
the aircraft GPS, for example). Anytime GPS data is sent to the sensor via the API commands, it
will be written to the image metadata, overriding the DLS 2 internal GPS data for five seconds
(or until another update is sent via the API).
HTTP Connection
Attach a USB Ethernet adapter or USB Wi-Fi adapter to one of the USB 3 ports. See the
for connection details and information. For HTTP API details, visit
Serial Connection
Use the provided pigtail from the host connector cable to connect to your serial device. See
the Input and Output section of this document for pin layout and details. Visit
to learn more about communicating with the MAVLink API.
