Attachment A Planet Labs Inc. Earth Station Application April 2015 Page 1 of 3 Description of Request Planet Labs Inc. (“Planet Labs”) hereby requests authority to operate an earth station located at 1625 Richardson Hwy, Fairbanks, Alaska. The proposed earth station will transmit at 450.0 MHz, and receive at 401.3 MHz. The earth station will be in communications with the authorized Planet Labs Constellation of Non-Geostationary Orbit (“NGSO”) Earth Exploration Satellite Service (“EESS”) satellites. 1 The frequencies in this application have already been authorized for transmission and reception to and from the authorized Planet Labs Constellation for early-phase and emergency-backup telemetry, tracking and command operation (“TT&C”). 2 The 401-402 MHz band, which is authorized for Space Operations on a secondary basis for non-federal users, is used as a secondary TT&C space-to-Earth link.3 The 449.75-450.25 MHz band, which is authorized for space telecommand, subject to agreement obtained under No. 9.21, is used as a secondary TT&C Earth-to-space link.4 This site is a TT&C-only site and thus will not utilize any of the other authorized frequencies granted under Call Sign S2912. Planet Labs transmissions will not cause harmful interference to Federal and non- Federal stations operating in accordance with the Table of Frequency Allocations. Planet Labs also accepts any interference to it that is caused by those allocated services.                                                                                                                         1 See File No. SAT-LOA-20130626-00087 (approved 12/03/13), File No. SAT-MOD-20140321-00032 (approved 06/18/14), and File No. SAT-MOD-20140912-00100 (approved 10/23/14), Call Sign S2912. 2 Ibid   3 See 47 C.F.R. § 2.106; In the Matter of Orbital Imaging Corporation, DA 99-353, at ¶¶ 3,8 (1999). 4 See 47 C.F.R. § 2.106, footnote 5.286 and US87.
