A new discovery linked an unmanned Azeri drone downed this week by Nagorno Karabakh Republic Defense Army to a U.S. Defense company that manufactures signal distribution products. This raises new questions about potential violations of U.S. arms export laws, Asbarez reported.

The Karabakh Army downed a drone on early September 12 morning, saying it had violated Karabakh airspace.

A close review of a video of the drone wreckage released by the Karabakh Army revealed that the Pueblo West, Colorado-based GPS Source Inc., which manufactures and sells signal distribution products is the maker of a GPS splitter that was one of the components of the downed drone. The GPS splitter allows a single GPS antenna to be shared between multiple GPS receivers.

An earlier examination of the video revealed that the Canadian-based company, NovAtel, which has offices in Texas, is the manufacturer of the GPS antenna used on the drone.
