ICAO WG-M
December 2000

2. GLOBALink/HF - Beginnings October 1998
3 ground stations
San Francisco, California, U.S.A.
Molokai, Hawaii, U.S.A.
Reykjavik, Iceland
2 customers
Cathay Pacific (1) B
Lufthansa Cargo (5) MD-11F
1,007 kilobits of traffic passed
At the start, the HFDL Service had three ground stations and 6 total aircraft using the system.

3. GLOBALink/HF - Now December 2000
12 Ground Stations
San Francisco, California, U.S.A.
Molokai, Hawaii, U.S.A.
Reykjavik, Iceland
Riverhead, New York, U.S.A
Auckland, New Zealand
Hat Yai, Thailand
Shannon, Ireland
Johannesburg, South Africa
Barrow, Alaska, U.S.A.
Krasnoyarsk, Russia
Santa Cruz, Bolivia
Guam
As of December 2000, there are 12 ground fully operational ground stations deployed each operating with 2 transmitters, except for Iceland, which has three transmitters. The temporary station at Anchorage will be taken off the air in January 2001 and is not included in the 12 ground stations.

4. GLOBALink/HF - December 2000 Continued
20 customers
Over 115 HFDL-equipped aircraft
Aircraft added at rate of 2-3 per month since January 2000
Over 36,000 kilobits of traffic passed
91% increase in traffic since January 2000
There are now 20 airline customers using HFDL with 115 HFDL-equipped aircraft.

5. GLOBALink/HF Flight Tracks (9/00)
This maps, showing the flight paths of HFDL Customers, represents the performance data packets received from the HF Data Radios by ARINC. The colors represent the ground station that the aircraft was logged on to. Data is represented for the month of September.

Primary coverage
Secondary coverage
The green represents nominal coverage for the HFDL system. Stations added this year include: Krasnoyarsk, Russia; Barrow, Alaska; Santa Cruz, Bolivia; and Guam. ARINC completed its coverage of the polar flight routes with the installation of Russia and Barrow. Crews are currently installing the permanent TCI-530 antennas in Barrow now that the permafrost is solid. Krasnoyarsk is currently using Russian dipole antennas until the permanent TCI-530 antennas can be installed in the spring.

7. GLOBALink/HF Growth Trend
Increasing HFDL traffic.

8. GLOBALink/HF Uplink Performance (System Wide)
Block success and message success rates have held constant throughout the year. This is one indicator that the adaptive frequency management techniques employed by ARINC have supported communications as we approach the peak of the solar cycle.
ARINC expects that the uplink success to improve with the installation of the 4 new stations late this year and

9. Service Enhancements North Polar coverage
Implemented October 2000
HFDL is the only data link available for North Polar operations
Adaptive frequency management
ARINC partnered with Radio Propagation Service, Inc. (RPSI) for adaptive frequency management
RPSI algorithms optimize coverage by controlling the daily/hourly operating frequencies at all HFDL ground stations
New Ground Stations Sites (1Q 2001)
Bahrain
Gran Canaria, Canary Islands
Implement / Planned service enhancements include:
* Coverage of polar routes achieved this year with Krasnoyarsk and Barrow
* Implemented Adaptive Frequency Management (Modify frequency management tables for geomagnetic and solar storm activity) with RPSI (Radio Propagation Services, Inc. (John Goodman)).
* New ground stations to be installed in Bahrain and the Canary Islands the first quarter of 2001.

11. Service Enhancements ATS Validation
Trials begin December 2000
Participants
NavCanada
Continental Airlines
Message set
Waypoint position report via HFDL to CADS to NavCanada
B configured for fully automatic generation and transmission of message - ADS
Planned ATS applications
Automatic Dependent Surveillance (ADS)
Controller Pilot Data Link Communications (CPDLC)
Implement through trials and demonstrations with HFDL-equipped aircraft in 2001
Service Enhancements contineud:
* ATS validation trials in the North Atlantic to begin mid-December with Continental Airlines and NavCanada. These trials will be ADS only.
* Expect to add additional applications in other regions in 2001 through trials and demonstrations with HFDL-equipped aircraft.

12. Service Enhancements Industry Standards HFDL Performance Monitoring
ICAO SARPS - Published
RTCA MOPS - Completed, approval expected 12/00
MASPS - Planned completion 9/01
HFDL Performance Monitoring
Begin performance evaluation by region with NATS ADS Trials
Monitor / Track Avionics Performance
Goal: Meet or Exceed customer / CAA requirements
ARINC HFDL Points of Contact:
Service Enhancements Continued:
* RTCA MOPS to be presented to RTCA PMC in December
* ARINC has taken the lead to complete the MASPS in 2001
* Performance monitoring and improvement a key goal for 2001 as ATS trials begin and the full ground station compliment is in place. The goal is to meet or exceed the customer and CAA requirements. Starting performance analysis by region.
