FCC Form 442 Exhibit 2 File #: 0220-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 BRIO satellite. SpaceQuest has selected Spaceflight Industries of Seattle, Washington as the launch provider. BRIO will be launched on a SpaceX Falcon 9 launch vehicle from Vandenberg, AFB in California (geographic coordinates 34.5762°N; 4.2803°W) in November 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: BRIO  BRIO 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. BRIO Value Total Number of Orbital Planes: 1 Celestial Reference Body: Earth Inclination Angle (degrees): 97.52 Orbital Period (seconds) 5760 LTAN 22:30 Apogee 575 km Perigee 575 km Figure 1 Orbital Parameters 3 Service Area. Worldwide 4 Satellite Payload. The primary satellite mission of BRIO is to investigate, identify and resolve potential technical and implementation issues with its advanced satellite SDR radio design developed by Myriota. Another important objective is to demonstrate the ability to upload and run new firmware that can introduce new features to the SDR Radio after it is on orbit. The results of this Exhibit 2 SpaceQuest PAGE 3

FCC Form 442 Exhibit 2 File #: 0220-EX-CN-2018 Technical Information three-phase experiment will (1) demonstrate and validate the ability to uplink large numbers of messages to a satellite using a single channel, (2) demonstrate the ability to downlink messages to different ground devices on a single channel, and (3) implement an advanced signal processing algorithm on board a satellite to provide highly spectrally efficient bidirectional communications. The BRIO 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 Myriota payload and upload new computer firmware to improve performance and correct any software deficiencies. 5 Principle Specifications. BRIO is a 3U CubeSat whose outside envelope measures 100 x 100 x 340.5mm. The satellite’s total mass is 5 kg. It has four deployable solar arrays, which 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 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 BRIO satellite will not 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. The Software Defined Radio implements the S-Band transceiver. The deployed array and antenna configuration is shown in Figure 3. Command Receiver Exhibit 2 SpaceQuest PAGE 4

FCC Form 442 Exhibit 2 File #: 0220-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. A third UHF antenna that is deployed from the side of the satellite when the solar panels are deployed is for a UHF SDR transceiver, which is a part of the experimental communications payload being evaluated for the hosted Myriota payload. 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 a backdoor command receiver at 145.92 MHz. The second UHF Transceiver used to evaluate Myriota’s advanced communications processor will also operate in 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. The space-to-Earth frequency band of 2200-2202 MHz will be used to downlink experimental test data to Earth Stations in Limestone, Maine and Esrange, Sweden. The Earth-to-space uplink frequency band of 2045-2046 MHz from Limestone, Maine and Esrange, Sweden will be used occasionally to upload new firmware to the Myriota payload.

Elevation Angle 11 Interference Analysis 11.1 400.50-400.65 MHz (TT&C and Experimental 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 and Experimental 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 2200-2202 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 S-Band downlink transmissions will operate at 2201 MHz band from Esrange, Sweden and LimeStone, Maine where . The S-Band downlink carrier frequency of 2201 MHz will be used for the BRIO satellite and coordinated with other authorized users of the band. S-Band operations will occur periodically at either LimeStone, Maine or Esrange, Sweden. Transmissions will be restricted as necessary to eliminate interference with other users of the band. Exhibit 2 SpaceQuest PAGE 13

FCC Form 442 Exhibit 2 File #: 0220-EX-CN-2018 Technical Information 11.4 2045-2046 MHz (Payload Uplink) SpaceQuest’s S-Band satellite receiver and antenna system is designed to operate in the 2025-2110 MHz band. The S-Band uplink carrier frequency of 2045.5 MHz will be used for BRIO and coordinated with authorized users of the band. The 2045-2046 MHz band was chosen for the BRIO experimental license because it can be supported with the chosen S-Band radio equipment – the GomSpaceSR2000 S-Band SDR Receiver and ANT2000 antenna. Infrequent S-Band uplink transmissions from Limestone, Maine or Esrange, Sweden, will be used to load new firmware to the BRIO satellite and to send confirmations of successful data packet downloads. 12 Power Flux Density Analysis 12.1 400.60 MHz (TT&C Downlink) The Power Flux Density for the UHF TT&C downlink is shown in Figure 16.
