Attachment – Form 42 FCC Experimental License 1. Overview Harris Corporation is requesting an FCC Experimental License within the allocated UAS C Band (5030 – 5091 MHz) to perform testing and validation of our Command & Non-Payload Communications (CNPC) Radio System. We will install a Mobile CNPC Radio in an Unmanned Air Vehicle (UAV) and communicate to the UAV via a Fixed CNPC Base Station Mobile Station. Our experimental UAS operations will be conducted within 17km (10 miles) of the Harris Corporation Manufacturing facility located in Malabar, FL. The UAV will be operated below 400’ Above Ground Level (AGL) and In Accordance With (IAW) all applicable FAA rules 2. Harris Command & Non-Payload Communications (CNPC) Radio System Harris Corporation is participating in several key FAA UAS initiatives, including FAA Pathfinder, FAA UAS test site projects, the RTCA Drone Advisory Committee and RTCA SC-228. We have also been an active participant in RTCA SC-228 “Minimum Performance Standards for Unmanned Aircraft Systems” and the follow-on Phase 1 Terrestrial-based CNPC Link (Command & Non-Payload Communications) committee Based on this experience, Harris is developing initial UAS CNPC Radio and Beyond Visual Line of Sight (BVLOS) network capabilities which are at various levels of maturity given current state of the UAS standards such as RTCA DO-362 and the more recently published FAA Technical Standard Order (TSO) C213. Our CNPC Radio systems are now at a point in development that we are ready to perform controlled RF radiation testing to verify the integrity and performance of the radio. Following the receipt of approval from the FAA we are hereby requesting an Experimental License from the FCC to further continue our testing. 3. Test Site Area (Malabar, FL) The planned Test Site is centered on Harris Corporation’s Manufacturing facility located at 2800 Jordan Blvd. Malabar, FL. This is a remote area rural area with a small General Aviation Airport (Valkaria) located about 1 1/2 miles from the Harris facility. We will closely coordinate our flight tests with Valkaria Airport Manager (Steve Borowski). 2

Attachment – Form 42 FCC Experimental License Test Site Area of Operation 4. C Band Spectrum for Unmanned Air Systems (UAS) The FAA has designated C Band Spectrum (5030 – 5091 MHz) for use by UAS. Additionally, the FAA Spectrum Office has recommended the band be divided into 41 channels, which are allocated based on the Data Class of operation and required bandwidth. This Experimental License application request is for a “Low, Medium and High-end” 85 kHz channel (3 Total) to support initial testing of the Harris Command and NonPayload Communication (CNPC) radio designed to support UAS Operations. Our request is to allow Manufacturing Testing of the Harris CNPC Radio for channels 3, 23 and 39 for both D1 and D2 as shown in the table below: 5. Coordination with FAA The requested C Band allocation is within the FAA Aviation Protected Spectrum and therefore requires pre-coordination and approval from the FAA prior to applying for an Experimental License from the FCC. Correspondingly, we have been closely coordinating with the FAA Spectrum Engineering Office and the use of these (12) channels have been determined to be acceptable to the FAA.

Attachment – Form 42 FCC Experimental License 9. Harris CNPC Airborne (Mobile) Radio The Harris CNPC radio is a Software Defined Radio (SDR) that has been guided by the evolution of UAS Industry Standards and our participation in SC-228, RTCA MOPs and RTCA DO-362. Our CNPC Radio implementation incorporates quad core processors, the latest generation Field Programmable Gate Array (FPGA), and a state of the art programmable frequency agile transceiver. The radio is a Technology Readiness Level of 7 and sufficiently mature to support Experimental Tests and demonstrations. The Harris CNPC radio supports the C-band spectrum approved by the FAA for UAS CNPC radio use. The radio has 2 RF SMA Connectors to support the option of 2 Spatial Diversity antennas, required to mitigate against multipath propagation losses, reducing Bit Error Rates, and improving overall link performance. The radio also includes a connector J1 main interface, providing DC Power Input, USB, Ethernet, RS-232, etc. and a J2 camera interface, providing video inputs. 11

Attachment – Form 42 FCC Experimental License A web-based Graphical User Interface (GUI) is used to configure the radio. The radio control screen allows the operator to configure both ends of the link. A health and status monitoring feature is available via the GUI as well. 10. Harris CNPC (Fixed) Base Radio System The Harris ground radio system includes a Harris CNPC radio, RF power amplifier (RFPA), and DC power supply. The RFPA increases the RF Power to 10 watts (40 dBm), which fulfills the need to close the CNPC Link with sufficient margin (12dB), while capable of supporting a minimum data rate of 20 kbps throughout all phases of planned UAV flight. For the Experimental License we plan on using a COTS omnidirectional C-band antenna with a gain of 1 dBi. The CNPC ground radio system will be housed in a NEMA enclosure and mounted on a portable telescopic antenna mast that extends a minimum of 12 feet Above Ground Level (AGL). Note: Depending on area ground clutter it may be necessary to increase the height of the C Band Antenna to maintain VLOS with the HALE UAV. The Harris CNPC Base Station will be configured as shown in the figure below: 12

Unmanned Air Vehicle (UAV) Mobile Antenna We will evaluate several small form factor blade antennas, that are certified for aircraft use that are vertically polarized, low gain (<3 dBi), omnidirectional, with elevation patterns that are near- hemispherical in coverage such as the Octane and Taoglas mini-UAV antennas shown below: 1.
