(4) Telecommand signals for propulsive maneuvering of a reentry vehicle for return and recovery.

(c) The use of Space Launch Services licenses for on-orbit communications after a launch vehicle separates from its payload are not permitted, provided that a space launch station may be used for telemetry, tracking, and telecommand activities for the incidental orbiting of a launch vehicle before or after it has separated from its payload. The use of Space Launch Services licenses for such incidental orbiting are permitted only to the extent necessary for space launch operations.

§ 26.5 Terms and definitions.

Base station. A station at a specified site authorized to communicate with mobile stations.

Equivalent isotropically radiated power ( EIRP ). The product of the power supplied to the antenna and the antenna gain in a given direction relative to an isotropic antenna (absolute or isotropic gain).

Expendable launch vehicle. A launch vehicle whose propulsive stages are used only once.

First stage of a launch. The first 15 minutes of flight.

Fixed service. A radio communication service between specified fixed points.

Fixed station. A station in the fixed service.

Frequency coordination. The process of obtaining the recommendation of a frequency coordinator for a frequency(ies) that will most effectively meet the applicant's needs while minimizing interference to licensees already operating within a given frequency band.

Frequency coordinator. An entity or organization that has been certified by the Commission to recommend frequencies for use by licensees in the Space Launch Services.

Harmful interference. For the purposes of resolving conflicts between stations operating under this part, any emission, radiation, or induction which specifically degrades, obstructs, or interrupts the service provided by such stations.

Itinerant operation. Operation of a radio station at unspecified locations for varying periods of time.

Launch vehicle. A vehicle built to place a payload or human beings from Earth in a suborbital trajectory, in Earth orbit, or otherwise in outer space.

Mobile service. A radio communication service between mobile and land stations, or between mobile stations.

Mobile station. A station in the mobile service intended to be used while in motion or during halts at unspecified points.

Reentry vehicle. A vehicle designed to return from Earth orbit or outer space to Earth substantially intact. A reentry vehicle is regarded as a launch vehicle in the context of a space launch operation only to the extent that it is being used for launch purposes.

Reusable launch vehicle. A launch vehicle that is designed to return to Earth substantially intact and may be launched more than one time or that contains vehicle stages that may be recovered by a launch operator for future use.

Space launch operations. Any activity that places a launch vehicle, whether an expendable launch vehicle or a reusable launch vehicle or reentry vehicle used for launch, and any payload or human being from Earth in a suborbital trajectory, in Earth orbit, or otherwise in outer space, including pre-launch testing and recovery or reentry of the launch vehicle.

Telecommand. The transmission of non-voice signals for the purpose of remotely controlling a device.

Telemetry. The transmission of non-voice signals for the purpose of automatically indicating or recording measurements at a distance from the measuring instrument. In the context of space launch operations, telemetry is diagnostic information, transmitted from the launch vehicle to ground controller stations during the flight, which allows the ground controller station to track the performance of the launch vehicle.

Universal Licensing System ( ULS ). The consolidated database, application filing system, and processing system for all Wireless Telecommunications Services. The ULS offers Wireless Telecommunications Bureau (WTB) applicants and the general public electronic filing of all applications requests, and full public access to all WTB licensing data.

§ 26.101 Eligibility.

The following entities are eligible for Space Launch Services licenses:

(a) A non-Federal entity that conducts space launch operations; or

(b) A parent of such entity or a subsidiary of such entity if either conducts space launch operations.

§ 26.102 License period; renewal.

Licenses for stations in the Space Launch Services will be issued for a term of ten years from the date of original issuance, or renewal. Prior to expiration of the term of a license, the space launch licensee shall submit to the Commission an application for the renewal in accordance with part 1, subpart F, of this chapter. Such renewal application shall certify that, during the preceding license term, the licensee operated and continues to operate consistent with Commission rules in this chapter and the terms of its existing authorization, including the operation of stations consistent with the terms of frequency coordination performed during its license term.

§ 26.103 Licensing.

The 2025-2110 MHz, 2200-2290 MHz, and 2360-2395 MHz bands are authorized on a non-exclusive nationwide basis for Space Launch Services. Non-exclusive nationwide licenses will serve as a prerequisite for registering launch sites and individual fixed, base, itinerant and mobile stations, as well as individual coordinated launches. A Space Launch Services licensee cannot operate a launch site and corresponding fixed, base, itinerant or mobile stations before registering it under its license and may only operate a station after that station has been cleared to operate in a particular frequency band in connection with a particular launch pursuant to the post-grant frequency coordination process set forth in Subpart C of this part. Space Launch Services licensees must delete registrations for unused launch sites and unused fixed, base, itinerant and mobile stations to maintain database integrity and facilitate coordination with other users of the 2025-2110 MHz, 2200-2290 MHz, and 2360-2395 MHz bands.

§ 26.104 Regulatory status.

Licensees are permitted to provide services on a non-common carrier basis. A licensee may render communications services consistent with the regulatory status in its license and with the Commission's rules in this chapter applicable to the Space Launch Services.

§ 26.105 Authorization required.

(a) General rule. Stations in the Space Launch Services must be used and operated only in accordance with the service rules set forth in this part, including the terms of the frequency coordination performed pursuant to subpart C of this part, and with a valid authorization granted by the Commission under the provisions of this part, except as specified in paragraph (b) of this section.

(b) Restrictions. The holding of an authorization does not create any rights beyond the terms, conditions, and period specified in the authorization. Authorizations may be granted upon proper application, provided that the Commission finds that the applicant is qualified in regard to citizenship, character, financial, technical, and other criteria, and that the public interest, convenience, and necessity will be served. See 47 U.S.C. 301, 308, 309, and 310.

§ 26.302 Emission masks.

(a) 2025-2110 MHz. For frequencies offset from the assigned frequency less than the 50 percent of the necessary bandwidth, no attenuation is required. At a frequency offset equal to 50 percent of the necessary bandwidth, an attenuation of at least 8 dB is required. Frequencies offset more than 50 percent of the necessary bandwidth shall be attenuated by the following mask:

Equation 1 to Paragraph (a)

Where:

f d is the frequency displaced from the center of the emission bandwidth.

B n is the necessary bandwidth, which is determined in accordance with Annex J of the NTIA Manual of Regulations and Procedures for Federal Radio Frequency Management (NTIA Manual) (incorporated by reference, see § 26.305).

dBsd is dB attenuation in a 4 kHz bandwidth, relative to the maximum power in any 4 kHz bandwidth within the necessary bandwidth (0 dBsd), where attenuation in this sense refers to the reduction in level relative to the reference, 0 dBsd, unless otherwise specified.

The unwanted emission mask rolls off at 40 dB per decade to a maximum attenuation of 60 dBsd, at which point it continues on both sides of the carrier for all frequencies beyond this point; see Annex M of the NTIA Manual regarding measurement requirements (incorporated by reference, see § 26.305); for any narrowband or single frequency unwanted emission which is not spread by the modulation process, the required attenuation shall be at least 60 dBc, where dBc is attenuation below the mean transmit power, rather than the dBsd value determined in equation 1 to this paragraph (a).

(b) 2200-2290 MHz. (1) During the first stage of a launch, all spectral components larger than −[55 + 10xlog(P)] dBc ( i.e., larger than −25 dBm) at the transmitter output must be within the spectral mask calculated using the following equation:

Equation 2 to Paragraph (b)(1)

M(f) = K + 90 log(R)−100 log |f-fc|; |f-fc| ≥ R/m

Where:

M(f) = power (dBc) at frequency f (MHz).

K = −20 for analog signals.

K = −28 for binary signals.

K = −61 for FQPSK-B, FQPSK-JR, SOQPSK-TG.

K = −73 for ARTM CPM.

fc = transmitter center frequency (MHz).

R = bit rate (Mbps) for digital signals or (Δf +fmax)(MHz) for analog FM signals.

M = number of states in modulating signal (m = 2 for binary signals, m = 4 for quaternary signals and analog signals).

f = peak deviation.

fmax = maximum modulation frequency.

(2) After the first stage of a launch, the emission mask set forth in paragraph (a) of this section shall apply.

(c) 2360-2395 MHz. (1) When using frequency modulation or digital modulation for telemetry or telecommand with an authorized bandwidth equal to or less than 1 MHz the emissions must be attenuated as follows:

(i) On any frequency removed from the assigned frequency by more than 100 percent of the authorized bandwidth up to and including 100 percent plus 0.5 MHz, the attenuation must be at least 60 dB, when measured in a 3.0 kHz bandwidth. This signal need not be attenuated more than 25 dB below 1 milliwatt.

(ii) On any frequency removed from the assigned frequency by more than 100 percent of the authorized bandwidth plus 0.5 MHz, the attenuation must be at least 55 + 10 log 10 pY dB when measured in a 3.0 kHz bandwidth.

(2) When using frequency modulation or digital modulation for telemetry or telecommand with an authorized bandwidth greater than 1 MHz, the emissions must be attenuated as follows:

(i) On any frequency removed from the assigned frequency by more than 50 percent of the authorized bandwidth plus 0.5 MHz up to and including 50 percent of the authorized bandwidth plus 1.0 MHz, the attenuation must be 60 dB, when measured in a 3.0 kHz bandwidth. The signal need not be attenuated more than 25 dB below 1 milliwatt.

(ii) On any frequency removed from the assigned frequency by more than 50 percent of the authorized bandwidth plus 1.0 MHz, the attenuation must be at least 55 + 10 log 10 pY dB, when measured in a 3.0 kHz bandwidth.

§ 26.303 Power limits.

(a) 2025-2110 MHz. The equivalent isotropically radiated power (EIRP) transmitted in any direction towards the horizon by an earth station in the 2025-2110 MHz band of the Space Launch Services shall not (with limited exceptions) exceed the following limits:

(1) +40 dBW in any 4 kHz band for u ≤0°;

(2) +40+3 u dBW in any 4 kHz band for 0°< u ≤5°; and

(3) Where u is the angle of elevation of the horizon viewed from the center of radiation of the antenna of the earth station and measured in degrees as positive above the horizontal plane and negative below it.

(b) 2200-2290 MHz. During the first stage of a launch, the EIRP of any station in the 2200-2290 MHz band of the Space Launch Services shall not exceed 25 Watts and the transmitter output power shall not exceed 25 Watts. In addition, the power flux-density at the Earth's surface produced by emissions from a transmitter operating after the first stage of a launch for all conditions and for all methods of modulation shall not exceed the following limits:

(1) −154 dB(W/m2) in any 4 kHz for angles of arrival less than 5° above the horizontal plane;

(2) −154 + 0.5 (δ−5) dB(W/m2) in any 4 kHz for angles of arrival δ (degrees) between 5° and 25° above the horizontal plane; and

(3) −144 dB(W/m2) in any 4 kHz for angles of arrival between 25° and 90° above the horizontal plane.

(c) 2360-2395 MHz. The EIRP of any station in the 2360-2395 MHz band of the Space Launch Services shall not exceed 25 Watts and the transmitter output power shall not exceed 25 Watts. Transmitter power may be increased to overcome line and duplexer losses but must not exceed 25 Watts delivered to the antenna.
