EAD Aerospace (EASA DOA PART21 FRA21 J&G), an Eclipse company, is now almost ready to finalize one of our Inmarsat GX Aviation Ka-band projects that we have been working on for the last year. Installing large satcom antennas is a long and complex path in terms of engineering and certification.
Firstly, the engineering design is critical to ensuring a safe and lightweight solution for installation of the heavy satcom antenna, and one that will ultimately deliver a good service to the customer.
And secondly, due to the fact that Ka-band antenna installations are still a novelty at EASA (European Aviation Safety Agency) and it remains their role to ensures the safety of the installation particularly taking into consideration the effects of Bird Strike, Lightning and Buffeting on the aircraft.
After more than 15 years developing satcom and connectivity STC’s for satcom service providers, satcom hardware OEMs and MROs, we are excited to be one of the pioneers to release a Ka-band STC. In our history, EAD Aerospace has always provide innovative and « outside the box » thinking, whilst maintaining total respect of aircraft safety and the regulatory rules issued by EASA and FAA. Of course, this is what lead to EAD Aerospace engineering the Satcom Universal Mounting System (SUMS).
SUMS V2 is one unique baseplate available in two attachment versions to comply with different Customers requirements :
- The baseplate is a fully compliant ARINC791 installation and is delivered with ARINC791 structural internal reinforcements. This solution is 100% ARINC791.
- Taking SUMS V1 design philosophy advantages. The baseplate allows attachment installation on top of frames: to minimize the impact to the A/C structure life with no structural doubler, to minimize part numbers, and to ease installation. This solution respects many ARINC requirements and is the lightest on the market – we like to call it the Hybrid.
SUMS in all its versions is hosting the Honeywell ARINC791 radome to ease airlines radome spares management already existing on GX linefit programs.
EAD Aerospace SUMS V2 design
About GX hardware installations : in order to provide an option to install the KRFU inside the fuselage (avoid heat under the radome on the ground in warmest countries) our engineers imagined and designed a bespoke RF hybrid waveguide/coaxial solution to connect the Jetwave Antenna to the KRFU. This solution was tested, respected all Honeywell specification and was proved as fully compliant in functional tests on first aircraft installation. EAD Aerospace also provides the KRFU installation outside the fuselage using a classic waveguide connection, should a customer wish to select this option.
EAD Aerospace is also working on other connectivity projects both in Ka- and Ku-band, and will continue to offer customized solutions for our customers.
2016 seems to be a pivotal moment for GX/KA connectivity, many things are occurring right now and we are proud to be part of this cutting edge adventure along with all our Partners and Customers.
Keep yourself updated for our STC issuance announcements !
