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).
