196 Van Buren Street #450 Herndon, Virginia 20171 (571) 203-0360 // www.he360.com November 28, 2017 RE: Amendment 0024-EX-CN-2017 HawkEye 360. Inc. (HE360) hereby amends the above-referenced application, which was filed on January 10, 2017, and amended on September 19, 2017, as follows: 1. Use of 2200-2290 MHz band HE360 will use the 2200-2290 MHz band (downlink) for LEOP and backup TT&C communications and transmit in this band only to two non-U.S. ground stations – a KSAT ground station in Svalbard, Norway and a Space Flight Laboratory ground station in Toronto, Canada.1 HE360 will not communicate with its U.S. ground station in the 2200-2290 MHz band unless authorized by the FCC to do so. Nonetheless, HE360 will maintain equipment at that facility with the capability to receive in the 2200-2290 MHz band. 2. Use of 8025–8400 MHz band HE360 clarifies that it will use the 8025-8400 MHz band (downlink) for primary TT&C and transmit in this band only to the KSAT ground station in Svalbard, Norway.2 There are no other changes to the application. To facilitate the FCC’s processing, provided below is a chart summarizing the relevant communications frequency bands HE360 proposes to use: Frequency Use 432-438 MHz Secondary TT&C uplink 2025-2110 MHz Primary uplink (only from non-U.S. ground stations) 2200-2290 MHz LEOP and secondary TT&C downlink (only to non-U.S. ground stations) 2410 MHz (center frequency) Cross-link (space-to-space) 8025-8400 MHz Primary downlink (only to non-U.S. ground station) 1 Prior to this amendment, HE360 had requested authority to receive communications in the 2200-2290 MHz band at its U.S. ground station on a backup emergency basis. 2 HE360 inadvertently had removed this frequency band from its Form 442 in the amendment application filed September 19, 2017. 1
