677-A0213 Cobham Aviator LGA-5005 HLD Enhanced Low Gain Antenna
677-A0213 Cobham Aviator LGA-5005 HLD Enhanced Low Gain Antenna, Aeronautical
The LGA-5005 is intended to comply with DO-262B, Appendix E, as part of an AES4 system.
LGA-5005 may only be installed with an AVIATOR-S CSDU [SDU-5045, part number 405045-vvccc] and SCM [SCM-5055, part number 405055-vvccc].
Together, these three items form a complete AES4 system, as defined in DO-262B, Appendix E. The LGA-5005 is powered by the CSDU (SDU-5045) of the AVIATOR 200S system.
System overview
The purpose of the LGA-5005 is to provide an L-band radio link between the Inmarsat SwiftBroadband Class 4 SATCOM system AVIATOR 200S and an Inmarsat I4 satellite.
For SwiftBroadband services, the LGA-5005 is part of a single channel aeronautical SATCOM system comprising the following subsystems (as defined in ARINC 781-6, Attachment 7, Configuration 3 [4]), interconnected as shown in Figure 2-2:.
