Sec. 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 Sec. 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.
