From: Rob Rainhart To: Doug Young Date: July 24, 2017 Subject: Request for Info - File # 0024-EX-CN-2017 ---------------------------------------------------------------------------------------------------------------- Message: The following information is provided in response to NTIA’s request for information: 1. Specific frequency that will be used by each CubeSat The satellite fly in a loose formation of three. Each satellite has primary and secondary TT&C links. It is important to note that the secondary links are only backups to the primary links and will not be used for main operations. Hawk #1 Primary Links Space to Earth – 8050 MHz Earth to Space – 2062.7 MHZ Hawk #1 Secondary Links Space to Earth – 2240 MHz Earth to Space – 435.365 MHz Hawk #2 Primary Links Space to Earth – 8175 MHz Earth to Space – 2068.1 MHZ Hawk#2 Secondary Links Space to Earth – 2246 MHz Earth to Space – 435.365 MHZ Hawk #3 Primary Links Space to Earth – 8300 MHz Earth to Space – 2207.4 MHZ Hawk #3 Secondary Links Space to Earth – 2256 MHz Earth to Space – 435.365 MHZ 2. Any spacing of the CubeSats within the indicated orbit Two of the satellites are co-planer separated by ~250km. the third satellite is in a offset plane from the other two and performs a ~10km cross track maneuver between the two co-planer satellites. This is accomplished with either a change in inclination or RAAN. 3. Antenna gain/power split information for each CubeSat Hawk #1 Primary Links Space to Earth Antenna Gain – 7 dBi Earth to Space Antenna Gain – 7 dBi Hawk #1 Secondary Links Space to Earth Antenna Gain – 7 dBi Earth to Space Antenna Gain – 7 dBi

Hawk #2 Primary Links Space to Earth Antenna Gain – 7 dBi Earth to Space Antenna Gain – 7 dBi Hawk#2 Secondary Links Space to Earth Antenna Gain – 7 dBi Earth to Space Antenna Gain – 7 dBi Hawk #3 Primary Links Space to Earth Antenna Gain – 7 dBi Earth to Space Antenna Gain – 7 dBi Hawk #3 Secondary Links Space to Earth Antenna Gain – 7 dBi Earth to Space Antenna Gain – 7 dBi 4. Location of all ground stations supporting these CubeSats (US and international) As filed we are planning one ground station in Herndon, VA subject to this request. We have begun negotiations on a ground station, supplied by KSAT, in Svalbard as a leased service. We have not completed the contract for this location yet but expect to in the next few weeks at which time we can amend this application with that ground station location. 5. Transmit frequency of each ground station supporting these CubeSats Herndon, VA Location: Hawk #1 Primary Links Space to Earth – 8050 MHz Earth to Space – 2062.7 MHZ Hawk #1 Secondary Links Space to Earth – 2240 MHz Earth to Space – 435.365 MHz Hawk #2 Primary Links Space to Earth – 8175 MHz Earth to Space – 2068.1 MHZ Hawk#2 Secondary Links Space to Earth – 2246 MHz Earth to Space – 435.365 MHZ Hawk #3 Primary Links Space to Earth – 8300 MHz Earth to Space – 2207.4 MHZ Hawk #3 Secondary Links Space to Earth – 2256 MHz Earth to Space – 435.365 MHZ 6. Transmit power for ground stations supporting these CubeSats Primary Links (SBand Uplink) Earth to Space – 100 Watts

Secondary Links (UHF Uplink) Earth to Space – 100 Watts 7. Antenna gain/power split information for each ground station supporting these CubeSats Hawk #1 Primary Links Space to Earth Antenna Gain – 48.18 dBi Earth to Space Antenna Gain – 36 dBi Hawk #1 Secondary Links Space to Earth Antenna Gain –48.18 dBi Earth to Space Antenna Gain – 12 dBi Hawk #2 Primary Links Space to Earth Antenna Gain – 48.18 dBi Earth to Space Antenna Gain – 36 dBi Hawk#2 Secondary Links Space to Earth Antenna Gain –48.18 dBi Earth to Space Antenna Gain – 12 dBi Hawk #3 Primary Links Space to Earth Antenna Gain – 48.18 dBi Earth to Space Antenna Gain – 36 dBi Hawk #3 Secondary Links Space to Earth Antenna Gain –48.18 dBi Earth to Space Antenna Gain – 12 dBi Regards, Rob Rainhart VP, Engineering HawkEye 360, Inc. 719-649-0243 rob@HE360.com
