503H8

• 1.2m – 3.4m or greater antennas

• Required integration between antenna and modem

• OpenAMIP protocol developed

2005

503H8

2006• More complicated beam handoff• Persistent IP address across satellite beams

503H8

• Antenna size less than 60cm

• Direct sequence spread spectrum developed to mitigate adjacent satellite interference

2007

503H8

2008• Antenna

• Flat panel or radome• Fuselage, hatch or tail

• High speed, skew angle• Prevalence of Roll-on/Roll-off

503H8

• EIRP map server incorporated into NMS

• Allow for modem to make intelligent decisions on when to change beams based on signal stream

2009

503H8

• Gulf Oil Spill• ISR requires larger and

faster data streams• SCPS returns utilized • Pushing upper limits @

6 MB/S 12”

2010/2011

503H8

2012• iDirect Government developed Airborne modems with

Single Board Computer (SBC) for protocol translation• Enable mission flexibility

503H8

2013/2014• Improved G/T EIRP map• ARINC 791 Standard

• OpenAMIP incorporated as the antenna to satellite modem protocol

503H8

2015• Support HTS• Make before break

• Dual demodulators

• Frequency reuse
