Description
Scope of this MOPS
The RTCA has supported the FAA for several years in developing the MOPS needed to support UA flights within U. S. Airspace for unmanned aircraft operated under 14 CFR Part 91 “General Operating and Flight Rules.”1 Between 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 UAS detect and avoid (DAA) system (the focus of SC-228 Working Group 1) and a UAS C2 Link System (the focus of SC-228 Working Group 2). This section provides a description of the UAS terrestrial-based (i.e., not satellite-based) CNPC Link System MOPS.
Figure 1-1 depicts the general operational concepts addressed in this MOPS, i.e., terrestrial-based point-to-point links represented by the yellow and red radio frequency (RF) links (the yellow links between the ground antenna and the UA and multiple red links between the tower antenna(s) and the UA. It also depicts the links from the High Altitude Relay System ground (BGRS) antenna up to and down from the High Altitude Relay System UA (see the blue solid links)) and then down to or up from other UA (flying at lower altitude) using the High Altitude Relay System (see the blue links). It should be noted (as depicted by the dotted blue RF links) that this MOPS supports the ability for UA to transfer between the Hight Altitude Relay System and a terrestrial ground based (red tower system) CNPC Link System. The networking reqirements can be found in the DO-377 [1] and that tests and other materials to certify a networked system are not part of this standard.
1 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).
