    1. Modern Loran Receivers: Current Performance and Future Enhancements by Linn Roth, Ph.D. Locus, Inc.

    3. Modern Loran Receivers vs 1990 Technology Receivers. Example Differences:

    4. Antiquated Loran Infrastructure Control Currently Limits Loran System Performance

    5. Example Accuracy with Current Infrastructure

    6. FAA Tech Center Flight Tests - August 2001

    7. FAA Tech Center Data: Sacramento Airport Close-up View of Landing and Takeoff

    8. FAA Tech Center Data: Sacramento Airport Close-up View of Landing and Takeoff

    9. FAA Tech Center Data: Atlantic City, NJ Airport Close-up View of Aug. 20 Takeoff and August 28 Landing

    10. Derivation of “Quasi-ASFs” and Example Application to Flight Data

    11. Example SatMate Quasi-ASF Results: Close-up of Atlantic City Airport

    12. Modern Loran Technology: H-field Antennas E-field H-field

    15. SatMate 1020 Tests, H-field Antenna 5/1/02 flight tests with Ohio University in Madison, WI Included 10 ILS-guided approaches WAAS GPS - Green; SatMate - Black Simultaneous recording, positions updated 1/sec SatMate 1020 using quasi-ASFs

    16. SatMate 1020 Tests, H-field Antenna

    17. SatMate 1020 Tests, H-field Antenna 3 representative examples of ILS-guided approaches SatMate 1020 using quasi-ASFs generated ~ 8 miles from airport SNRs 5-10 dB lower than expect to achieve Results will improve with: better transmitter control, airport-generated ASFs improved receiver software and antenna hardware

    18. Same 10 ILS Guided Approaches, No ASFs
