ADS-B for sUAS

The Federal Aviation Administration (FAA) is charged with the safety and efficiency of the National Airspace System (NAS) operations. (Safety: The Foundation of Everything We Do, 2017). This exploratory study will investigate the benefits, if any, on the implementations of Automatic Dependent Surveillance-Broadcast (ADS-B) technology on sUAS. (Federal Aviation Administration, 2018).
I can foresee the FAA enforcing this requirement on sUAS as it has for general aviation. I believe this implementation of ADS-B on sUAS will not have a measurable positive impact on safety or efficiency. The market is gearing up to meet the demands of the requirement by miniaturizing the ADS-B e.g. Ping2020 (The world’s smallest and lightest ADS-B solutions for sUAS, 2016) and TIM-SC1 (Miniature ADS-B Technology for sUAS & UTM/U-Space Implementation, 2018).
From a design standpoint, we know the implementation of design modifications after production is a higher cost proposition (Austin, 2010). It will increase the production cost on the new models. It will cost money to the existing user on both retrofitting costs and down time. From the safety standpoint, the FAA currently has systems/procedures in place which protect both the public and manned aircraft. The FAA does not allow certain operations yet created a waivers procedure to allow these operations. This waiver procedure serves as notice to the manned aircraft pilot. The responsible pilot can find this information by calling flight service briefer, via Notice to Airmen (NOTAM) (Notam retrieval, 2010) and several mobile applications and websites. ADS-B will not improve positional integrity reporting as compared to secondary radar service areas (Syd Ali, 2016) and it does not improve my image gathering for the preparation of maps.
Safety is the responsibility of both the sUAS and the manned aircraft pilots. See and avoid is the responsibility of both pilots. While the manned pilot may not be able to see the sUAS he can mitigate. The remote pilot shall follow procedures and be vigilant.
