§ 87.145 Acceptability of transmitters for licensing.
(a) Each transmitter must be certificated for use in these services,
except as listed in paragraph (c) of this section. However, aircraft
stations which transmit on maritime mobile frequencies must use
transmitters certificated for use in ship stations in accordance with
part 80 of this chapter. Certification under part 80 is not required
for aircraft earth stations transmitting on maritime mobile-satellite
frequencies. Such stations must be certificated under part 87.
(b) Some radio equipment installed on air carrier aircraft must meet
the requirements of the Commission and the requirements of the FAA. The
FAA requirements may be obtained from the FAA, Aircraft Maintenance
Division, 800 Independence Ave., SW., Washington, DC 20591.
(c) The equipment listed below is exempted from certification. The
operation of transmitters which have not been certificated must not
result in harmful interference due to the failure of those transmitters
to comply with technical standards of this subpart.
(1) Flight test station transmitters for limited periods where
justified.
(2) U.S. Government transmitters furnished in the performance of a U.S.
Government contract if the use of certificated equipment would increase
the cost of the contract or if the transmitter will be incorporated in
the finished product. However, such equipment must meet the technical
standards contained in this subpart.
(3) ELTs verified in accordance with § 87.147(e).
(4) Signal generators when used as radionavigation land test stations
(MTF).
(d) Aircraft earth stations must correct their transmit frequencies for
Doppler effect relative to the satellite. The transmitted signal may
not deviate more than 335 Hz from the desired transmit frequency. (This
is a root sum square error which assumes zero error for the received
ground earth station signal and includes the AES transmit/receive
frequency reference error and the AES automatic frequency control
residual errors.) The applicant must attest that the equipment provides
adequate Doppler effect compensation and where applicable, that
measurements have been made that demonstrate compliance. Submission of
data demonstrating compliance is not required unless requested by the
Commission.
