Downwelling Light Sensor 2 (DLS 2)
The Downwelling Light Sensor (DLS 2) is an advanced incident light sensor that connects
directly to RedEdge-MX. During a mission, the DLS 2 measures the ambient light and sun
angle for each of the five bands of the camera and records this information in the metadata
of the TIFF images captured by the camera. This information can then be used by
specialized processing tools (like Pix4Dmapper) to correct for global lighting changes in the
middle of a flight, such as those that can happen due to clouds covering the sun.
In addition, the DLS 2 provides GPS data to RedEdge-MX unless GPS data is provided from
an external source as outlined earlier in this guide. If using an alternative GPS source, the
GPS receiver will remain on at very low power (uBlox C/A code GPS @ 5 Hz).
