HARRIS CORPORATION EXPERIMENTAL STA APPLICATION FILE NO. 0505-EX-ST-2019 EXHIBIT 1 - DESCRIPTION OF EXPERIMENT Harris Corporation ("Harris") hereby requests experimental Special Temporary Authority (“STA”) to operate an experimental X-band ground terminal located in Malabar, Florida to support communications with a LEO earth observation satellite. The proposed ground terminal will provide Telemetry Tracking & Command data to the LEO satellite and will receive Thematic Mapper and sensor data from the LEO satellite. The terminal will consist of a Comtech T242XR, 4.2M carbon fiber parabolic reflector, with a circularly polarized feed, mounted on an XY positioner capable of pointing at any elevation 10 degrees above the horizon at any azimuth. Harris will not cause harmful interference to any stations operating in accordance with the Table of Frequency Allocations and will use its best efforts to avoid and mitigate any issues that may arise. Because the equipment is technically incapable of providing station identification, Harris respectfully requests a waiver of the station identification provisions of Section 5.115 of the Commission's rules, 47 C.F.R. § 5.115. All network traffic will be simulated traffic only, solely for evaluation purposes and not for the purpose of providing network data communications services to user stations. Harris submits that a grant of this STA request is necessary and in the public interest as it is anticipated that it will lead to commercial sensor improvements for earth sensing. The stop buzzer contact for this project is Kim Singleton – Satellite Operations Manager (Mobile: 321-446-2262), and an alternative stop buzzer contact is Rod Nelson - Chief Engineer (Mobile: 321-544-6477), e-mail: gnelso03@harris.com.

Comtech Introduction Comtech Space & Component Technology has developed a cost-effective X/Y antenna pedestal technology that specializes in precision antenna tracking. Our systems are specifically designed for low and medium earth orbits that support Remote Sensing, Earth Observation, and TT&C applications. We offer a range of X/Y tracking antennas from 30 centimeters to 11 meters coupled with our installation expertise and worldwide support in extreme environments such as the Arctic, Middle East and Tropics. Comtech Space & Component Technology provides the customer a complete satellite and tracking solution for your ground stations. Type 1 Deployable with non-ground Type 1 on a platform Type 2 ground mount penetrating mount Features: ■■ 30 centimeters to 11 meters antenna size ■■ Program and Auto Track Performance ■■ X/Y axis configuration (Series A through Type 6 for increasingly larger ■■ Effective program track capabilities that utilize ephemeris data in dishes) the form of Two Line Element (TLE) data and other formats ■■ Transmit/receive feed technologies through V-band ■■ Autotrack Capabilites: ■■ Designed for tracking LEO, MEO, HEO and GEO spacecraft »» Low loss mode coupler tracking system for high frequencies and ■■ Applications include Earth Observation, Remote Sensing, larger aperture antennas that does not affect G/T performance Communications and TT&C functions »» Software assisted autotrack - the low velocity tracking dynamic ■■ Lights-out operation, including ethernet (TCP/IP) and M&C software of the X/Y allows the implementation of real time signal level is provided with Linux-based M&C system, includes SNMP and XML peaking throughout the track by utilizing unique tracking support algorithms to control the servo control system Radome Options: The Comtech X/Y Antenna Systems do not require a radome for operation, but for extreme locations Comtech can provide a cost-effective radome solution. A radome offers many advantages like protection from extreme weather conditions, extension of component life and provides antenna position concealment. ■■ Radome Diameter Sizes: 1.5 meters to 20 meters (larger on request) tuned for the frequency or frequencies of interest ■■ Foam Core Sandwich Composition – three types of construction ■■ ‘A’ sandwich consisting of three layers ■■ ‘C’ sandwich consisting of five layers ■■ ‘S’ space frame design using a fiberglass framing with a reinforced PTFE-impregnated glass fiber (Teflon) fabric (ideal for wideband applications) Antenna in 5m radome with integrated ■■ Wind Speed: Radomes capable of surviving in winds up to 200 km/hr – 300 km/hr (depending on ring wall specific model) 1.800.557.5869 © 2019, Comtech Telecommunications Corp.

Additional Features & Options: ■■ Deployable, trailer, truck and skid mounts ■■ High-performance shaped Cassegrain feed configurations ■■ Multi-frequency feed systems ■■ Highly-responsive installation and maintenance services ■■ Full RF and data chain including: »» Frequency converters, spectrum analyzers, RF switching, demodulators/ modems, uplink amplifiers ■■ Mode coupler auto-track and software RSSI auto-track (ideal for X/Y low dynamic) Type 1 on trailer mount Type A Micro Deployable Type 5 ground mount Deployable with breakaway X/Y mount X/Y System Advantages: Cost Advantage: Simplified and elegant design, advanced manufacturing techniques, and use of commercial components makes the X/Y one of the most cost-effective antenna products available in the industry High Performance: ■■ System eliminates the “keyhole” at zenith or “cone of silence” associated with overhead passes experienced on other pedestal configurations ■■ Less dynamic tracking motion of the X/Y antenna over an El/Az provides for more accurate pointing, which is especially important when tracking Ka-band ■■ Low dynamic of movement greatly reduces system wear, thus extending the system life and reducing maintenance ■■ No cable wrap issues; no need for rotary joints or slip rings ■■ Precision gear assemblies eliminate drive-system backlash Delivery: 14 to 26 weeks (ARO) for the 1st system, delivery schedules will vary based on system requirements, antenna size and factory loading at the time of the order. Some X/Y positioner stock is maintained on the shelf and ready for delivery, please inquire. Carbon Fiber Reflectors: No need to heat the dish to avoid expansion and contraction as temperatures Type 5 on a tower change; greater gain performance over an aluminum dish, especially at the higher Ka-band through V-band ranges. Heated reflectors for ice and snow removal are available. Environmental Resilience: System designed for operation in coastal, arctic, and desert environments. 1.800.557.5869 © 2019, Comtech Telecommunications Corp. All rights reserved.
