Re:          Supplement to Karousel LLC, Applications for Satellite Space Station
             Authorizations, File No. SAT-LOA-20161115-00113

Dear Ms. Dortch:

Karousel LLC (“Karousel”) submits this letter to supplement its space-station application filed November 15,
2016.1

Section 25.146(a) directs applicants to provide a technical showing that “the proposed NGSO FSS system
would not exceed the validation equivalent power flux-density (EPFD) limits as specified in section 25.208
(g), (k), and (l) for EPFDdown, and EPFDup.”2 Karousel provided a detailed technical analysis showing
compliance.3 But the specific type of software analysis identified in section 25.146(a) – namely, PFD masks
“generated in accordance with the specification stipulated in the most recent version of ITU-R
Recommendation S.1503, ‘Functional Description to be used in Developing Software Tools for Determining
Conformity of Non-GSO FSS Networks with Limits Contained in Article 22 of the Radio Regulations’” – was
unavailable at the time of submission. Karousel’s Application therefore requested a six-week waiver of
section 25.146(a) to allow the company to perform the precise PFD modeling described in the rules.4
Attached is an analysis that shows PFD masks generated using the specification stipulated in the most
recent version of ITU-R Recommendation S.1503.

Please contact me with any questions related to this letter.

                                                      Respectfully submitted,

                                                      /s/ Monish Kundra

                                                      Monish Kundra
                                                      Vice President
                                                      Karousel LLC
