SPECIFIC INSTRUCTIONS FOR SCHEDULE S

Schedule S, along with the FCC 312 Main Form, is to be completed when:

• Applying for a license for a new space station;

• Amending a pending space station application, when information in a previously-filed Schedule S is being amended;

• Applying for a license for a replacement satellite;

• Applying for a modification of a space station authorization, if information in Schedule S on file would be modified; and

• Filing a Petition for Declaratory Ruling seeking to access the U.S. market, including requests for a space station to be added to the Permitted list, or an earth station application requesting new authority to serve the United States with a non-U.S.-licensed space station.

PURPOSE OF FILING

Schedule S is used for space station filings that do not involve assignments of license or transfers of control. It collects technical and operational data associated with space station license and market access applications. An applicant must complete Schedule S and the associated FCC 312 Main Form (which is referred to as “Form 312” in the International Communications Filing System (ICFS) and in these instructions) when filing an application for: (1) a license for new space station(s); (2) an amendment to a pending space station application that include changes to the previously-submitted Schedule S; (3) a modification to an existing space station authorization that include changes to the Schedule S on file; or (4) a request for new authority to use non-U.S. licensed satellites to provide service in the United States. Collection of this data is intended to expedite the Commission’s review of satellite applications.

Important Note: Schedule S does not collect all of the information required by the Commission’s rules with respect to space stations. In addition to the information required in this form, the applicant is required to provide all other information specified in section 25.114 of the Commission’s rules, 47 CFR § 25.114. This information, as well as any other information that the applicant wishes to provide in connection with the application, may be attached in ICFS as exhibits to the Form 312.

FILING PROCEDURES

Applicants are strongly encouraged to first complete and save the information required in the associated Form 312. After completing Form 312, the user will be prompted to complete Schedule S, if required. For amendments and modifications to an application, the applicant is advised to immediately save its Form 312, upon first opening the form, in order for the most current version of the Schedule S in the underlying application to be uploaded and attached to the Form 312. An applicant may work on its Schedule S prior to filling out Form 312, but its Form 312 must be completed, and both Schedule S and Form 312 must be error-free, before submitting the entire application to the Commission via ICFS.

Important Note: All information marked by a red * in the Schedule S is required.

Options for Providing Information in Schedule S

Specify the contours for the receiving beam configuration with the smallest gain-to-temperature ratio and the highest required saturation power flux density. The proposed maximum coverage area must be clearly specified.

For space stations with shapeable beams that are also steerable: Include the contours that would result from moving the beam peak around the limit of the effective beam peak area and the 0 dB relative antenna gain isoline. The proposed maximum coverage area must be clearly specified.

For space stations with steerable beams that are not shapeable: Specify the applicable contours, as defined in section 25.114, with a description of the area that the steerable beam(s) is expected to serve, or provide the contour information described in section 25.114 of the Commission’s rules.

For geostationary satellites with large numbers of identical fixed spot beams: Other than DBS satellites, applicants may, as an alternative to the above, provide the predicted antenna gain contours for one transmit and receive antenna beam with one of the following supporting documents:

1. An area map showing all of the spot beams depicted on the surface of the Earth;

2. A table identifying the maximum antenna gain point(s) in latitude and longitude to the nearest 0.1 degree; or

3. A map of the isolines formed by combining all of the spot beams into one or more composite beams.

For non-geostationary satellites with large numbers of identical fixed spot beams: As an alternative to submitting the information above, applicants may specify the predicted antenna gain contours for one transmit and receive beam pointed to nadir, together with an area map showing all the spot beams depicted on the surface of the earth with the satellites’ peak antenna gain pointed to a selected latitude and longitude within the service area.

Service area / coverage area: Attach one or more GXT, TXT, DOC and/or PDF files for each receive and transmit beam. If all of the GXT and data files for the applicant’s beams are in a GIMS database container file, the associated MDB file can be attached. If a service area diagram is not being attached, provide a service area description that can be attached as service area data. Geographic designators such as State Codes, ITU Codes, or Figure Numbers can be used in the description to define the given service area for the particular beam.

FILING SCHEDULE S

Generating a PDF. At any time prior to submitting Schedule S, users may view, print, or save a PDF version of Schedule S by clicking the Schedule S Review button, and then clicking the Generate PDF button.

Checking for Errors

• When filling out the various sections and subsections of the Schedule S, users may click the Schedule S Review button on the Main Menu page. A list of errors will appear in a table under the “Schedule S Errors” tab on the “Schedule S Review” page. The errors are listed by Record, Field, Beam ID, Channel ID, and Error. Next to the “Schedule S Errors” tab, a hyperlink will take the user to the exact location of each error.

• As each error is corrected in a section or sub-section, click the Save Record button, then the Return to Menu button, and finally the Schedule S Review button to return back to the “Schedule S Errors” table.

• If an error has been corrected but is not reflected in the form, click the Validate Schedule S button to refresh the page.

Final Review and Submission

• The “Schedule S Review” page is provided for final review of the Schedule S.

• When the user clicks on the Validate Schedule S button and no more errors appear under the “Schedule S Errors” tab, a Submit Schedule S button will appear on the “Schedule S Review” page.

• Clicking the Submit Schedule S button will attach a PDF version of the completed Schedule S to the associated Form 312 and return the applicant to the Schedule S Main Menu page. The Schedule S Main Menu page will now appear as a greyed-out, unfillable version of the completed Schedule S.

• Once the Schedule S is complete, users may click the Form 312 button to return to the associated Form 312, to review and validate it before final submission of both the Form 312 and the associated Schedule S to the Commission.
