Amendment Narrative                                                                          Exhibit 1



                                 DESCRIPTION OF AMENDMENT TO

                      PENDING EARTH STATION LICENSE APPLICATION



      BlackSky Global, LLC (“BlackSky”) seeks to amend the pending application for a
new earth station as identified herein,1 to modify the operating transmit power of the
M2 Antenna Systems antenna model 450CP34, identified in the pending application as
FAI_UT.

        1. E40 Total EIRP for all carriers, and E48 Maximum EIRP per Carrier should be
           changed to 29.0 dBW
        2. E49 Maximum ERIP Density per Carrier and E60 Maximum EIRP Density
           toward the Horizon should be changed to 21.6 dBw/4kHz

       The increase in power level will not affect the power levels used to complete the
Radiation Hazard Study shown in Exhibit 1 to the original application nor any of the
information that was supplied to the Society of Broadcast Engineers in connection with
the frequency coordination with that group that is shown in Exhibit 2 to the original
application. The overall description of operations that is provided in Exhibit 3 to the
original application also remains current, except that the referenced satellite
constellation application has now been granted. Accordingly, those Exhibits previously
submitted are incorporated by reference. All other operating parameters requested in
the original application remain unchanged. Only the information relevant to the
changes above are included in the Schedule B submitted herewith.

     The power levels shown in the original application were calculated in error. This
amendment seeks to rectify that mistake in calculation.
