System Specifications
Macaw ILS ADC Lite ADC Micro ADC Snap µ-MCA RGB+3 Single Band Thermal IR

Hardware Configuration

Up to 15 bands of radiometric data collected at 1 second intervals are saved by the ILS ground station in a log file, without errors introduced by platform motion of a UAV. 12 bands can be configured in the field with narrow band-pass filters to match the characteristics of a measurement instrument or camera. The unit is a smart device, equipped with a Wi-Fi network browser interface which allows live display of the data being logged. The wireless interface can be used to retrieve the log file for calibration of images or measurements.

The ground station is designed as an accessory for all Tetracam ADC and MCA camera lines, and can be ordered with the camera, or purchased as an accessory for cameras already in the field. Calibration of the system is important, and can optionally be performed at Tetracam when the ground station is purchased, if the target camera can be sent back from the field.

The unit has an interface connector with power, ground, and RS232 serial I/O. It is shipped with a 9 volt battery adapter wired to a mating plug.

Software Features

The time stamps for the measurements in the log file allow the PixelWrench2 log distiller to automatically extract the radiometric data and insert it into the metadata field of images collected with a Tetracam ADC or MCA. The metadata is then used in PixelWrench2 and other software packages to adjust the pixel values in the image to represent true reflectance and exact color band ratios for vegetation index calculations.
