                                        Description of Request


            Planet Labs Inc. (“Planet Labs”) hereby requests authority to operate an earth
    station located at 2502 12th St N, Fargo, ND. 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 A Special Temporary Authority (STA) with the exact
    same technical and administrative characteristics has also been granted for this earth
    station site.3

             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.4 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.5 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.
