                                            Application Purpose

Harris Corporation ("Harris") hereby submits this FCC Form 312 application for a proposed 3.8
meter transmit/receive C Band earth station to be located in Old Town, Florida. This application
is a resubmission of its Form 312 application made with the Commission on June 07, 20131
under File No. SES-LIC-20130607-00474.

On August 12, 2013 the Commission dismissed File No. SES-LIC-20130607-00474 without
prejudice to refiling2 for the following reasons:

Harris lists the Total Input Power at antenna flange in Item E38 of its Schedule B
as 0.071 Watts for the digital emission designator 64K0G7W listed in Item E47.
However, the RF Radiation Hazard study provided as part of Harris’s application
lists the input power at antenna flange as 0.067 Watts. Furthermore, the stated
maximum input power of 0.071 Watts (-11.5dBW) does not appear to be
sufficient to close the link with SES-2. Therefore, if Harris elects to re-file this
application, it must confirm that the power requested is sufficient to close the link
with SES-2, submit a link budget in support of such a confirmation, and update
the frequency coordination.

Harris lists, in Items E54-58 of Schedule B, the eastern and western limits of the
satellite arc, the range of antenna elevation angles, and the range of antenna
azimuth angles. Specifically, Harris lists the antenna azimuth angle in the western
limit as 252.0 degrees. However, our computations show the antenna azimuth
angle in the western limit should be 251.5 degrees.

Harris has corrected the relevant portions of FCC Form 312, Schedule B within this application.
As requested, Harris is also supplying the link budget demonstrating that the power level noted
within the application is sufficient to close the link with SES-2.

Because this submission only supplies the corrected information as noted, an additional
application fee is not required pursuant to 47 C.F.R. § 1.1111(d).
