Differential GPS (DGPS) Control & VHF Data Broadcast (VDB) Cabinets

Airport Traffic Control Unit (ATCU)

VHF Data Broadcast (VDB) Antenna

• 3-4 RSMUs per Installation• 12/24/48 Channel DGPS Receiver• DGPS Reciever packaged in an

environmentally protective enclosure• Dual Element Multi-path Limiting

Antenna• Requires site survey and placement

against siting/installation criteria

• Dual 19” Rack & Panel Cabinets• Differential Correction Processor (L)• FAA-certified DO-178B Software• Power Distribution & Local Status (L)• Single/Dual VHF Transmitter/Receiver (R)• Maintenance Data Terminal (MDT)

• SLS Control Panel installed in Air Traffic Control Tower

• Flat Panel Touch Screen available in three configurations

• Elliptically polarized antenna• 3 Bay Lindenblad configuration• Single/dual VDB configurations• Secondary VHF Transmitter and

Antenna may be remotely located

PSP System Status: September Flight Test

26

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

27

PSP System Status: September Flight Test

• Planned flight testing- VDB coverage checks

Full orbit around the VDB at 23NMI3000’ AGL north and south radial passes

- A total of 100 straight-in approaches At least five to every runway end, one from 20NMI65 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

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
