Boeing 787 - Multi-Mode Receiver.

SpeedEdge contributed to the development and verification of the Multi-Mode Receiver (MMR) for the Boeing 787, enabling highly accurate positioning for CAT-III auto-landing. This involved advanced algorithms, model-based development and extensive verification to meet stringent aerospace standards.

The Challenge

Develop a high-precision navigation system for CAT-III auto-landing.
Implement complex positioning algorithms for multi-mode operation.
Ensure compliance with stringent aerospace safety and certification standards.
Achieve high verification coverage while managing project timelines.

Our Solution

Developed PVT module with almanac & ephemeris automation.
Implemented trilateration, Doppler processing and Kalman filtering algorithms.
Used model-based development (MATLAB/Simulink) for design and simulation.
Performed extensive verification with automated testing frameworks.
Ensured compliance with aerospace standards (DO-178B/C).

The Results

0.75 m CAT-III auto-landing position accuracy
6,000 Verification man-hours saved
100% Delivered on time
