The Honeywell/BendixKing 200-08825-0000 GPS Xpress Board is a non-field-serviceable receiver module that forms the core navigation processor of the KLN 94 GPS Navigation System. This compact board delivers precise location and timing data to support VFR, IFR enroute, terminal, and non-precision approach operations in certificated aircraft avionics installations.
## Technical Specifications
**System Certification:** TSO C129a
**Power Supply:** Accepts aircraft bus voltage from 11 to 33 volts through a flyback converter circuit. The power supply incorporates over-voltage and short-circuit protection.
**Physical Construction:** Compact board design with conformal coating for environmental protection. Integrates into the KLN 94 unit via one 37-pin D-sub connector, one 25-pin D-sub connector, and one BNC coaxial connector at the rear panel. Front-panel phone jack included.
## Key Features
• Outputs GPS data directly from the receiver card for navigation processing
• Computes present position information and provides guidance relative to user-defined flight plans
• Calculates crosstrack error, distance-to-waypoint, ground speed, track angle, time-to-waypoint, bearing-to-waypoint, and advisory VNAV guidance
• Supports instrument approach capabilities with aeronautical database
• Database updates via RS-232 serial interface
• Single-unit form factor eliminates field removal and replacement
## Typical Applications
Panel-mounted long-range GPS navigation for general aviation and certified aircraft requiring VFR and IFR navigation capability across multiple flight phases—enroute, terminal, and approach segments.
## Compatibility & Integration
Designed exclusively for the KLN 94 Navigation System. Compatible with aircraft electrical buses rated 11 to 33 volts. All connectivity through standard avionic connectors (37-pin and 25-pin D-sub, BNC). Operates as an integrated component within the KLN 94 avionics suite.
