Scope of this MOPS

The RTCA has supported the FAA for several years in developing the MOPS needed to support UA flights within the National Airspace System (NAS) and beyond the operational limits3 placed on small UAS. In 2006-2012 the RTCA Special Committee (SC)-203 sought to develop a MASPS document; although it was not completed, there was sufficient progress to provide much of the needed groundwork for this MOPS. In 2013 the RTCA initiated SC-228 with a narrower scope; namely to develop MOPS needed for (a) a UAS detect and avoid (DAA) system [focus of Working Group (WG) 1] and (b) a UAS Terrestrial CNPC Link System (focus of WG 2). This section provides a description of the scope of the UAS Terrestrial (not satellite) CNPC Link System MOPS.

The CNPC Link System components and interfaces for this MOPS are shown in Figure 1-2. It includes the set of equipment in the list given above: CNPC Link System Airborne and Ground Radios, corresponding antennas and the cabling between them.

The CNPC Link System, as described by the equipment items and their interconnections shown in Figure 1-2, does not include the many other systems needed for UAS to operate as depicted in Figure 1-1. Key aspects of those other systems are described in Section 1.4.

Simulations and flight tests using the MOPS Baseline CNPC Link System have been conducted to confirm the validity of this MOPS. This MOPS also includes verification methods that can be used to show compliance of proposed CNPC Link System designs based on this MOPS.

This MOPS does not include all CNPC Link System design characteristics, for example, support of multiple UA communicating with one CNPC Link Ground Radio System (GRS), or support of one CNPC Link System GRS communicating with CNPC Link System Airborne Radio Systems (ARS) manufactured by different companies. These capabilities would require some interoperability between the GRS and ARS.

The remainder of Section 1 includes the following subsections:

1.2 System Overview

1.3 CNPC Link Operational Applications

1.4 Intended Functions

1.5 Operational Goals

1.6 Assumptions

1.7 Test Procedures

1.8 Definition of Terms

3 The current limits placed on small UAS are described in the FAA’s June 29, 2016 in the Federal Register (Volume 81, No. 124/Rules and Regulations) which announces amending of regulations to allow for the operation of small unmanned aircraft systems in the National Airspace System. This adds a new Part 107 to Title 14 Code of Federal Regulations (14 CFR).
