What is a Satellite Landing System? Honeywell’s Satellite Landing System (SLS) is a ground-based navigation aid used to provide CAT I/II/III precision approach and landing capability. The SLS consists of the following major components:
Airport Traffic Control Unit (ATCU) Remote Satellite Measurement Unit (RSMU)
Differential GPS (DGPS) Control &

PSP System Status: September Flight Test
25
PSP System Status: September Flight Test • Stability testing began in Mid-August - Multiple planned and unplanned restarts have occurred - Several coding issues were found and repaired - Site parameter data adjustments are required LGF installation procedures require alignment with the ADDs
- Problems are in the “expected” category, and no major problems have been seen
• System was sufficiently stable for flight testing
26
PSP System Status: September Flight Test • Planned flight testing - VDB coverage checks Full orbit around the VDB at 23NMI 3000’ AGL north and south radial passes
- A total of 100 straight-in approaches At least five to every runway end, one from 20NMI 65 approaches to a selected primary test runway end • RW36L was selected because it presents the greatest potential for interrupting GPS signal at the LGF

Lessons Learned from Flight Test • FAA Flight conducted Sept 18 through 28 - Honeywell technical support on site during flying - Flights included straight-in plus TAP legs. - Overall flight test was very successful • Adjustment to Type 4 Message Data - FAS segments adjusted to match ILS (TCH, etc.) - TAP legs added to Type 4 before flight test • Prototype Software Glitches - Some difficulty with new prototype software modules Still working to achieve Stability Test objectives
- Related to limits of prototype station - Able to patch software - Flight test continued and met or exceeded goals 30

Air Operations • A single ground station provides precision approach to all runway ends - Replaces multiple ILSs • Ground station transport, siting, operation, and maintenance are remarkably efficient • A single ground station enables numerous additional air operations
Benefit to Military Air Operations Worth Further Investigation
