Introduction

This document contains Minimum Operational Performance Standards (MOPS) for the Ground Based Surveillance System (GBSS) for Traffic Surveillance systems implemented with Unmanned Aircraft Systems (UAS) transiting and performing extended operations in Class D, E¹ and G airspace, along with transiting Class B and C airspace. It includes equipment to enable UAS operations near terminal areas during approach and departure in Class C, D, E and G airspace and off-airport locations. It does not apply to small UAS (sUAS) as defined in Title 14 of the Code of Federal Regulations (CFR) Chapter 107. Likewise, it does not apply to operations in the Visual Flight Rules (VFR) traffic pattern of an airport, nor to surface operations. These standards specify the surveillance system characteristics that should be useful for designers, manufacturers, installers and users of the equipment.

Compliance with these standards is recommended as one means of assuring that the equipment will perform its intended function(s) satisfactorily under the conditions specified herein. Any regulatory application of this document is the sole responsibility of appropriate governmental agencies.
