External Interfaces andthe Connector Board
• Goal:– All interfaces routed through and mounted on the
Connector Board• Reality:– Various different mountings and routings
necessary

Inertial Navigation System (INS)
• Determines:– Direction• Roll, pitch & yaw
– Velocity • Inertial Measurement Unit (IMU)
– Location• Global Navigation Satellite System (GNSS)
– Global Positioning System (GPS)– GLONASS
