Sagetech Corporation has shown that a PAE ISR Resolute Eagle UAS, equipped with a Sagetech XPC-TR-50 Mode C transponder
, can complete a mission in civil airspace, the company said.

You have less than four years until the January 1, 2020, mandate to have a working ADS-B Out system installed if you want regular access to airspace where a Mode C transponder currently is required.
You may be able to use it in conjunction with a Mode C transponder, which you'll likely have to retain anyway with 978 UAT, even in the U.
Following the intensive testing in co-operation, DoD AIMS1 Program Office with US Navy, contracted AIMS Mark XA certification to the Sagetech XPC-TR-50 Mode C transponder
, creating it the smallest, lightest transponder ever to receive this certification.
If an aircraft has a mode C transponder
as back-up, and its primary mode S transponder fails, then TCAS will provide warnings of impending collisions but will not be able to execute joint collision avoidance maneuvers.
2020, ADS-B Out deadline and associated installation costs ignores that the equipment only will be required essentially where a Mode C transponder
is required now: Class A, B and C airspace, plus at and above 10,000 feet msl.
Sandia actually labels the STX360 and STX180 products UAT ADS-B receivers, which happen to have a built-in Mode C transponder
airspace where the FARs now require a working Mode C transponder.
Perhaps the most glaring drawback of the 978 UAT flavor of ADS-B Out is the need for a working Mode C transponder even if you have ADS-B Out.
The table below summarizes the FAR's requirements, which basically substitute ADS-B OUT where a Mode C transponder
is required now.
On that date, operators will need ADS-B OUT to operate in airspace where a Mode C transponder
is presently required.
