Federal Register / Vol. 86, No. 19 / Monday, February 1, 2021 / Proposed Rules
conventional Ku-band, extended Kuband, conventional Ka-band, extended Ka-band, or 24.7525.25 GHz, that do not qualify for routine processing under relevant criteria in this section, 25.211, or 25.212 are subject to the requirements in 25.220.
15. Amend 25.220 by revising paragraph a to read as follows:
25.220 Non-routine transmit/receive earth station operations.

a The requirements in this section apply to applications for, and operation of, earth stations transmitting in the conventional or extended C-bands, the conventional or extended Ku-bands, or the conventional or extended Ka-bands that do not qualify for routine licensing under relevant criteria in 25.211, 25.212, or 25.218.

16. Revise 25.262 to read as follows:
25.262 Licensing and domestic coordination requirements for 17/24 GHz BSS space stations and FSS space stations transmitting in the 17.317.8 GHz band.

a A 17/24 GHz BSS or FSS applicant seeking to transmit in the 17.317.8 GHz band may be authorized to operate a space station at levels up to the maximum power flux density limits defined below without coordinating its power flux density levels with adjacent licensed or permitted operators, as follows:
i For 17/24 GHz BSS applicants, up to the power flux density levels specified in 25.140b3 only if there is no licensed space station, or priorfiled application for a space station transmitting in the 17.317.8 GHz band at a location less than four degrees from the orbital location at which the applicant proposes to operate; and ii For FSS space station applicants transmitting in the 17.317.8 GHz band, up to the maximum power flux density levels in 25.140a3iii, only if there is no licensed 17/24 GHz BSS space station, or prior-filed application for a 17/24 GHz BSS space station, at a location less than four degrees from the orbital location at which the FSS
applicant proposes to operate, and there is no licensed FSS space station, or prior-filed application for an FSS space station transmitting in the 17.317.8
GHz band, at a location less than two degrees from the orbital location at which the applicant proposes to operate.
b Any U.S. licensee or permittee authorized to transmit in the 17.317.8
GHz band that does not comply with the applicable power flux-density limits set forth in 25.140a3iii and/or 25.140b3 shall bear the burden of

coordinating with any future cofrequency licensees and permittees of a space station transmitting in the 17.3
17.8 GHz band as required in 25.114d15ii.
c If no good faith agreement can be reached, the operator of the FSS space station transmitting in the 17.317.8
GHz band that does not comply with 25.140a3iii or the operator of the 17/24 GHz BSS space station that does not comply with 25.140b3, shall reduce its power flux-density levels to be compliant with those specified in 25.140a3iii and/or 25.140b3
as appropriate.
d Any U.S. licensee or permittee of a space station transmitting in the 17.3
17.8 GHz band that is required to provide information in its application pursuant to 25.140a2 or b4 must accept any increased interference that may result from adjacent space stations transmitting in the 17.317.8 GHz band that are operating in compliance with the rules for such space stations specified in 25.140a and b, 25.202a9, and e through g, 25.210i through j, 25.224, 25.262, 25.264h, and 25.273a3.
e Notwithstanding the provisions of this sections, licensees and permittees will be allowed to apply for a license or authorization for a replacement satellite that will be operated at the same power level and interference protection as the satellite to be replaced.
17. Amend 25.264 by revising the section heading and paragraphs a introductory text, a1 and 2, and 6, b introductory text, b2 introductory text, b2ii, b3 and 4, c, d introductory text, d1ii, d2
introductory text, e introductory text, e1 introductory text, e2
introductory text, e3, f introductory text, f2, g, h introductory text, and i introductory text to read as follows:
25.264 Requirements to facilitate reverse-band operation in the 17.317.8
GHz Band.

a Each applicant or licensee for a space station transmitting in the 17.3
17.8 GHz band must submit a series of tables or graphs containing predicted off-axis gain data for each antenna that will transmit in any portion of the 17.3
17.8 GHz band, in accordance with the following specifications. Using a Cartesian coordinate system wherein the X axis is tangent to the geostationary orbital arc with the positive direction pointing east, i.e., in the direction of travel of the satellite; the Y axis is parallel to a line passing through the geographic north and south poles of the Earth, with the positive direction pointing south; and the Z axis passes

through the satellite and the center of the Earth, with the positive direction pointing toward the Earth, the applicant or licensee must provide the predicted transmitting antenna off-axis antenna gain information:
1 In the XZ plane, i.e., the plane of the geostationary orbit, over a range of 10 degrees from the positive and negative X axes in increments of 5
degrees or less.
2 In planes rotated from the XZ
plane about the Z axis, over a range of 20 degrees relative to the equatorial plane, in increments of 10 degrees or less.

6 The predictive gain information must be submitted to the Commission for each license application that is filed for a space station transmitting in any portion of the 17.318.8 GHz band no later than two years after license grant for the space station.
b A space station applicant or licensee transmitting in any portion of the 17.317.8 GHz band must submit power flux density pfd calculations based on the predicted gain data submitted in accordance with paragraph a of this section, as follows:
1
2 The calculations must take into account the aggregate pfd levels at the DBS receiver at each measurement frequency arising from all antenna beams on the space station transmitting in the 17.317.8 GHz band. They must also take into account the maximum permitted longitudinal station-keeping tolerance, orbital inclination and orbital eccentricity of both the space station transmitting in the 17.317.8 GHz band and DBS space stations, and must:
i
ii Indicate the extent to which the calculated pfd of the space stations transmissions in the 17.317.8 GHz band exceed the threshold pfd level of 117 dBW/m2/100 kHz at those priorfiled U.S. DBS space station locations.
3 If the calculated pfd exceeds the threshold level of 117 dBW/m2/100
kHz at the location of any prior-filed U.S. DBS space station, the applicant or licensee must also provide with the pfd calculations a certification that all affected DBS operators acknowledge and do not object to such higher off-axis pfd levels. No such certification is required in cases where the frequencies assigned to the DBS and to the space station transmitting in the 17.317.8
GHz band do not overlap.
4 The information and any certification required by paragraph b of this section must be submitted to the Commission for each license application
