                                        Description of Request


            Planet Labs Inc. (“Planet Labs”) hereby requests authority to operate an earth
    station located at 1 Meyn Rd., Half Moon Bay, California. 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.
