4 GLOBALink/HFDL Overview HFDL is a certified airline industry data linkAlong with VHF and SATCOM, HFDL provides ATC and AOC data link communications to the airline industryHFDL uses the same air-ground and ground-ground messaging protocolsDifference is in the link layer which uses the HF spectrum (3 – 30 MHz).Air-ground message transmission speed varies depending on radio wave propagation conditions.300, 600, 1200, or 1800 bpsARINC is the sole provider of HFDL service (GLOBALink/HF data link)HFDL industry approvalsICAO SARPs and HFDL ManualRTCA MASPSRTCA MOPSAEEC Specification 635Supports both AOC and ATC servicesOperates in the High Frequency band of RF spectrum 3-30 MHzSystem has the ability to adapt to ionospheric anomalies by changing speeds at which the air/ground link operatesNumerous standards were developed by ICAO, RTCA, and the AEEC in support of this service

Primary coverage is shown in green and secondary coverage is in blue. A good portion of the world has HFDL coverage as shown.One more station, Carnary Islands, is expected to be added later this year.

6 GLOBALink/HFDL Flights – July 2003 Here is a sample of HFDL flights that were recorded in July of 2003Primary routes used were in the North Atlantic. Secondary routes included Europe to Africa/Asia, North America to Asia, and North America to South America. Some polar routes are also seen on this map as well.As more aircraft equip with HFDL avionics, one can expect to see more growth on all routes shown.

8 GLOBALink/HFDL Summary Site and system upgrades continue to improve HFDL performance and enhance end-to-end reliabilityContinued growthImproved coverage through the addition of ground stations and HF frequenciesATC validation efforts ongoingFor questions or additional informationplease contact:Pete GroganProgram ManagerIn SummaryHFDL was developed and deployed to meet the aviation industry’s requirement for a cost-efficient, truly world wide data link service.HFDL’s operational performance is excellent and it continues to grow as a valued service to the industryARINC has committed to the full constellation of HFDL ground stations, which will be completed in the next few months when Las Palmas, Canary Islands is activated.We also recognize the effect that changing Solar conditions will have on the HF frequencies we use, and are licensing new ones around the world on a continuing basis.Obtaining approval from the Air Traffic Control authorities has been a challenging endeavor, but, with the help of involved industry organizations and our valued customers, we are closing in on that goal.This is the end of my presentation.I will be around for a while to answer any questions that you may have regarding this presentation or HFDL in general.Thanks for your time and interest.
