                                           Receive-Only Mobile Earth Station Application for STA
                                                                                       Exhibit A

          EXHIBIT A – REASON FOR SPECIAL TEMPORARY AUTHORITY


        Deere & Company (“Deere”), pursuant to Section 25.120(b)(3) of the Commission’s
Rules, 47 C.F.R. § 25.120(b)(3), hereby requests special temporary authority (“STA”) for a
period of 60 days to operate receive-only, non-common carrier, mobile earth stations operating
in the L-band at center frequency 1545.9675 MHz to downlink transmissions from an Inmarsat
geostationary satellite at 98° west longitude (Satellite Identifier: Inmarsat 4F3), in conjunction
with downlinks from other Inmarsat geostationary satellites (collectively “Inmarsat Satellites”)
already authorized.1 Deere requests the instant authority to begin no later than March 22, 2016.
Specifically, Deere requests STA for its existing network of mobile earth terminals (“METs”)
operating under Call Sign E130083 to receive 2.5 kHz space-to-earth emissions (designator
2K50D1D) from the Inmarsat Satellites at the above-referenced center frequency.2

        Since 2001, Deere has been enabling domestic agricultural equipment with its StarFire
precision farming system. The StarFire system employs receive-only vehicle mounted mobile
earth stations. These earth stations receive L-band space-to-earth emissions from Inmarsat
geostationary satellites that provide correctional data. This data augments the navigational
information the StarFire terminals receive simultaneously from Global Positioning System
(“GPS”) satellites. This augmented system enables the operators of domestic farming equipment
to pinpoint their location to within +/- 2.5 centimeters.3 This precise positioning capability
developed originally to assist farmers in comparing the crop yields from various fields to
determine, among other things, the amount of fertilizer and seed appropriate for a particular field
and crop, has now found additional important uses to improve farming efficiency, including
enabling farmers to manually record observations such as weed patches, crop appearance, and
other field variables with remarkable precision. In addition, among other benefits, when coupled
to the vehicle steering system through the Deere AutoTrack system it aids the operator to steer a
more precise path when making repeated passes over the same track, thus greatly reducing crop
and soil damage.

        Grant of STA will serve the public interest by ensuring continuity of service for existing
Deere StarFire customers during the pendency of Deere’s permanent application to modify Call
Sign E130083 to receive the above-referenced frequencies.4 Pursuant to Section 25.120(b)(3) of
the rules, Deere requests a 60-day STA without the need for prior public notice. As discussed

1
    All involved Inmarsat spacecraft have been approved to serve the United States, and are reflected on
    the Commission ISAT list.
2
    Deere was previously granted authority to receive space-to-earth emissions from additional Inmarsat
    Satellites. See IBFS File No. SES-LIC-20130422-00340 (granted Feb. 9, 2016). Deere has filed an
    application to modify Call Sign E130083 to permit Antennas 1, 2, and 3 to operate on center
    frequency 1545.9675 MHz. See IBFS File No. SES-MOD-20160227-00183 (filed Mar. 1, 2016).

    Navigational accuracy depends on several variables, including visibility to overhead satellites and
    other supplemental transmitters providing correctional data.

                                       Receive-Only Mobile Earth Station Application for STA
                                                                                   Exhibit A

above, grant of authority is requested on or before close of business on March 22, 2016 so that
Deere can continue to provide service to customers without any loss of service.
