ADS-B is emerging as the defacto standard for manned aircraft in the context of NextGen ATM. There are several advantages to ADS-B, but most ADS-B gear was developed for manned aircraft, and some smaller versions have been developed for UAVs recently. However, even the smallest currently-available ADS-B transponder is still about 250g, which is not suitable for small UAVs, such as those becoming popular for civilian use in the US. KalScott proposes to develop a micro ADS-B unit, which is light enough, inexpensive enough, and uncomplicated enough that it can be adopted readily for small civilian UAVs.
