FCC Form 442 Exhibit 2 File #:0176-EX-CN-2018 Technical Information 1 Ownership, Operations and Construction. SpaceQuest, Ltd. is a small business concern, and the owner, manufacturer and operator of the THEA satellite. SpaceQuest has selected Spaceflight Industries of Seattle, Washington as the launch provider. THEA will be launched on a SpaceX Falcon 9 launch vehicle from Vandenberg, AFB in California (geographic coordinates 34.5762°N; 4.2803°W) in October 2018. Pursuant to Part 5 §5.64 of the Commission’s Rules, construction of the proposed experimental satellite and associated facilities has begun prior to the Commission’s grant of an authorization. This is necessary given the nature of satellite construction and technical requirements over long lead times. Such construction is entirely at SpaceQuest’s risk without any assurances that its proposed experiment will be subsequently approved.  Space Station Name: THEA  THEA Estimated Construction Completion Date: August 2018  Spaceflight Final Certification of Licenses (Go/NoGo): September 1, 2018  Purpose: Experimental, non-Common Carrier basis  Orbital Type: NGSO 2 Orbital Requirements. The satellite is designed to operate in a circular sun-synchronous orbit as described in Figure 1. The satellites are based on COTS technology that allows for small, lightweight and low-cost spacecraft. THEA Value Total Number of Orbital Planes: 1 Celestial Reference Body: Earth Inclination Angle (degrees): 97.52 Orbital Period (seconds) 5760 Apogee 575 km Perigee 575 km Figure 1 Orbital Parameters 3 Service Area. United States 4 Satellite Payload. The primary satellite mission of THEA is to test an experimental spectrum survey payload developed by Aurora Insight, a US company. The Aurora payload is an experiment to demonstrate and validate the ability of its flight computer firmware to monitor, process and generate relevant measurements of the spectral environment in the 1.35 to 8.0 GHz band using a novel wideband antenna developed by Flexitech Aerospace. The secondary satellite mission of THEA is to test a new “Backdoor” receiver developed by SpaceQuest to Exhibit 2 SpaceQuest PAGE 3

FCC Form 442 Exhibit 2 File #:0176-EX-CN-2018 Technical Information send executive commands, to reboot the satellite flight computer, or to cycle the spacecraft power bus in the event of a system failure. As a components manufacturer, it is expected that the outcome of this testing will result in a significant advancement in satellite radio equipment technology. The THEA UHF frequency assignment will be used for satellite telemetry, command and control. The S-Band assignment will be used to download selected mission data from the Aurora payload and upload new computer firmware to improve performance and correct any software deficiencies. 5 Principle Specifications. THEA is a 3U CubeSat whose outside envelope measures 100 x 100 x 340.5mm. The satellite’s total mass is less than 5 kg. It has four deployable solar arrays, which will deploy from the short edges of the spacecraft. The LiIon battery consists of eight cells wired as 4- series and 2 parallel. The expected mission lifetime of the satellite is 5 years in a 575-km orbit due to battery life and deorbit analysis. SpaceQuest will own and operate the experimental CubeSat throughout its mission lifetime. The THEA satellite will never be sold or transferred to another party. 6 System Block Diagram. Figure 2 below shows the major components of the spacecraft and their interfaces. The flight computer is responsible for TT&C and payload scheduling. The attitude determination and control system orients the solar panels to the sun, except when the satellite is re-oriented to communicate with a ground station. Two Software Defined Radios are shown below, one is for an S-Band transceiver and the other is for the Aurora experimental wideband receiver. The deployed array and antenna configuration is shown in Figure 3. Exhibit 2 SpaceQuest PAGE 4

FCC Form 442 Exhibit 2 File #:0176-EX-CN-2018 Technical Information Figure 2 System Block Diagram Figure 3 Isometric view of deployed configuration This configuration allows for two VHF and two UHF monopole antennas deployed from the body of the spacecraft. One UHF antenna is used for TT&C communication. The second UHF antenna is grounded. The receive-only VHF monopole antennas are used to test SpaceQuest’s new “backdoor” receiver to send executive commands to reboot the satellite flight computer in the event of a system failure. 7 Telemetry, Tracking & Command and Payload Operations The space-to-Earth downlink frequency band of 400.50-400.65 MHz and the Earth-to-space uplink frequency band of 399.90-400.05 MHz for TT&C communications will communicate with SpaceQuest’s Earth stations in Fairfax, Virginia, Naalehu, Hawaii, North Pole, Alaska, and Limestone, Maine. The SpaceQuest TT&C Earth stations will also have the capability to uplink executive commands to the backdoor command receiver at 145.92 MHz. The space-to-Earth frequency band of 2200-2290 MHz will be used to downlink experimental test data to Earth Stations in Inuvik, Canada and Esrange, Sweden. The Earth-to-space uplink frequency band of 2025-2110 MHz from Inuvik, Canada and Esrange, Sweden will be used occasionally to upload new firmware to the Aurora payload. 8 Radio Equipment. 8.1 UHF Transceiver  NanoComm A-100 UHF Transceiver manufactured by GomSpace.  Primary transceiver capability for telecommand, telemetry, and schedule uploads.

FCC Form 442 Exhibit 2 File #:0176-EX-CN-2018 Technical Information 11 Interference Analysis 11.1 400.50-400.65 MHz (TT&C Downlink). Interference with U.S. federal and commercial assignments in the 400.50-400.65 MHz band is unlikely as transmissions will only occur while over the SpaceQuest TT&C ground stations. The 400.50 to 400.65 MHz space-to-Earth band is allocated for UHF Little LEO data services and has been used experimentally by SpaceQuest for the past 5 years 11.2 399.90 -400.05 MHz (TT&C Uplink) Interference with U.S. federal and commercial assignments in the 399.00-400.05 MHz band is unlikely as uplink transmissions will only occur while over the SpaceQuest TT&C ground stations. The 399.0-400.05 MHz Earth-to-space band is allocated for UHF Little LEO data services and has been used by SpaceQuest experimentally for the past 5 years. 11.3 2200-2290 MHz (Payload Downlink) The GomSpaceSR2000 S-Band SDR Transmitter and ANT2000 Antenna is designed to operate in the 2200-2290 MHz band. In order to avoid interference with the U.S. Federal allocation in the 2200-2290 MHz band, all S-Band operations will occur outside of the United States. The nominal S-Band downlink carrier frequency of 2288.5 MHz was selected for analysis for the THEA satellite, but only a 1.0 MHz channel in the 2200-2290 MHz band will be used and coordinated with other authorized users of the band. S-Band downlink operations will occur several times each day at either Inuvik, Canada or Esrange, Sweden. Transmissions will be restricted as necessary to eliminate interference with other users of the band. 11.4 2025-2110 MHz (Payload Uplink) SpaceQuest’s S-Band satellite receiver and antenna system is designed to operate in the 2025-2110 MHz band. The nominal S-Band uplink carrier frequency of 2045.5 MHz was chosen for analysis for the THEA satellite, but only a 1.0 MHz channel in the 2025-2110 MHz band will be used and coordinated with other authorized users of the band. The 2025-2110 MHz band was chosen for the THEO experimental license because it is the only frequency band that can be supported with the existing S-Band radio equipment – the GomSpaceSR2000 S-Band SDR Receiver and ANT2000 Antenna. In order to avoid interference with the U.S. Federal allocation in the 2025-2110 MHz band, all S-Band operations will occur outside of the United States. Infrequent S-Band uplink transmissions from Inuvik, Canada or Esrange, Sweden, will be used to load new firmware to the THEA satellite and to send confirmations of successful data packet downloads.

It has a 0 dBi average gain and a radiation pattern shown in Figure 18. Figure 18 UHF Satellite Transmit/Receive Antenna Radiation Pattern. Exhibit 2 SpaceQuest PAGE 15

FCC Form 442 Exhibit 2 File #:0176-EX-CN-2018 Technical Information 13.3 VHF: THEA Space Station Receive Antenna The same ISIS Deployable Omnidirectional Antenna has a VHF monopole element, which is used to receive emergency commands to reboot the flight computer or to power cycle the spacecraft in the event of a single event latch up. This small, sensitive, very low-power receiver design that operates at a different, fixed frequency than the primary UHF TT&C receiver, can save a mission. SpaceQuest will perform sensitivity tests of the receiver in order to characterize its performance in the space environment. The omni-directional radiation pattern is shown in Figure 19. Figure 19 VHF Satellite Receive Antenna Radiation Pattern 13.4 Broadband: THEA Space Station Receive Antenna A novel wideband antenna from Flexitech Aerospace is mounted in the “Tuna Can” of the THEA Cubesat. This receive-only antenna is used to capture RF spectrum in the frequency band from 1.35-7.075 GHz. The antenna pattern is a hemispheric 120 cone (60) with a peak gain at the center of the coverage envelope and a slow roll off to the -3dB point.
