American Aerospace Technologies, Inc. (AATI) is an industry-leading provider of airborne intelligence and communications systems and services for enterprise. Designed to address the requirements of critical infrastructure operators and emergency responders, InstiMaps™ is an end-to-end system that includes airborne sensors, analytics and communications systems that deliver critical airborne data through a cloud-based intelligence gateway to end users in near real-time.

AATI has integrated and flown a wide variety of sensors and devices on manned aircraft, Unmanned Aircraft Systems (UAS) and small electric drones including flying cell sites, survey-grade mapping payloads, precision weather sensors, methane probes and corona sensors, among others. The company helps its clients efficiently develop and evaluate use cases for airborne sensors and intelligence systems.

AATI has been flying long-endurance UAS “beyond visual line of sight” (BVLOS) in the National Airspace System since 2010. AATI has operated under eleven FAA-approved Certificates of Waiver or Authorization (COAs) and completed hundreds of safe and successful BVLOS UAS flights across the country. AATI also assists customers with large-scale airspace development and establishing UAS policies, procedures and best practices. The company has assisted customers in obtaining airspace approvals for UAS operations covering more than 16,000 square miles across the country.

AATI also produces UAS-related equipment for enterprise, serves as a Subject Matter Expert (SME) to many companies, and supports special projects. With over 14 years of operational experience built into its products and services, the company prides itself on its reputation for high performance, reliability and safety.

David Yoel

Founder and CEO

Dave is an applied physicist, entrepreneur, pilot and airspace expert with 35 years of combined experience in space systems, industrial manufacturing, remote sensing and aviation. As a graduate student, he was Payload Manager for the first university student experiment to fly on the Space Shuttle (STS-4 in June, 1982). He then worked for Boeing where he led space industrialization efforts during the early Shuttle era. In the ’90’s he manufactured industrial-scale furnaces to melt & refine metals and alloys, semiconductor crystals and other advanced materials. David founded AATI in 2002 as a space systems consulting firm. In 2010, AATI began delivering long-endurance UAS systems and providing flight services with both manned & unmanned aircraft. Yoel is the recipient of 3 patents on UAS and pipeline patrol and has authored numerous large area Certificates of Authorization. He is an AIAA Associate Fellow, Past-President of the Keystone Chapter of AUVSI and a member of the National Research Council’s NASA Aeronautics Research and Technology Roundtable.
