Nature of Business	Nature of Business PASSUR Aerospace, Inc. (“PASSUR” or the “Company”), a New York corporation founded in 1967, is a business intelligence company, providing predictive analytics and decision support technology for the aviation industry primarily to improve the operational performance and cash flow of airlines and the airports where they operate. PASSUR uses big data, within the aviation intelligence platform and a suite of web-based solutions that address the aviation industry’s intractable and costly challenges, including, but not limited to, the underutilization of airspace and airport capacity, delays, cancellations, and diversions. The Company’s technology platform is supported by its Aviation Intelligence Center of Excellence, a team of subject matter experts with extensive experience in airline, airport, and business aviation operations, finance, air traffic management, systems automation, and data visualization, with specific expertise in the operational and business needs, requirements, objectives, and constraints of the aviation industry. PASSUR’s mission is to improve global air traffic efficiencies by connecting the world’s aviation professionals onto a single aviation intelligence platform, making PASSUR an element in addressing the aviation industry’s system-wide inefficiencies. We are an aviation intelligence company that makes air travel more predictable, gate-to-gate, by using predictive analytics generated from our own big data – to mitigate constraints for airlines and their customers. PASSUR’s information solutions are used by the five largest North American airlines, more than 60 airport customers, including 20 of the top 30 North American airports (with PASSUR solutions also used at the remaining ten airports by one or more airline customers), over a hundred business aviation customers, and the U.S. government. PASSUR provides data aggregation and consolidation, information, decision support, predictive analytics, collaborative solutions, and professional services. To enable this unique offering, PASSUR owns and operates the largest commercial passive radar network in the world that updates flight tracks every 1 to 4.6 seconds, powering a proprietary database that is accessible in real-time and delivers timely, accurate information and solutions via PASSUR’s industry-leading algorithms and business logic included in its products. Solutions offered by PASSUR help to ensure flight completion, covering the entire flight life cycle, from gate to gate, and result in reductions in overall costs and carbon emissions, while helping to maximize revenue opportunities, as well as improving operational efficiency and enhancing the passenger experience. PASSUR’s commercial solutions give aviation operators the ability to optimize performance in today’s air traffic management system, while also achieving Next Generation Air Transportation System (“NextGen”) and Single European Sky ATM Research objectives. PASSUR integrates data from multiple sources, including its independent network of surveillance sensors installed throughout North America creating coast to coast coverage, as well as locations in Europe and Asia; government data; customer data; and data from third party partners. PASSUR’s sensors receive aircraft and drone signals in Mode A, C, S, and Automatic Dependent Surveillance-Broadcast (“ADS-B”), providing position, altitude, beacon code, and tail number, among other information. PASSUR receives signals from aircraft that, when combined with its historical database of aircraft and airport behavior, including information recorded by its network over the last 10 years, allow the Company to know more about what has happened historically and what is happening in real-time. In addition, the historical database allows the Company to predict how aircraft, the airspace, and airports are going to perform, and more importantly, how the aircraft, the airspace, and airports should perform.
