The space-based interceptor would use "advanced, optical" on-board sensors for guidance and would destroy their targets by impact.
The role of the race engineer on racing teams has grown in importance since the adoption of on-board sensors in vehicles to collect performance data.
The ECU collects and processes signals from various on-board sensors.
The vessels also generates 320 kW of electric power to feed a wide array of on-board sensors and equipment.
The special sensors and optics on-board provided photo reconnaissance capability.
Body fixed vectors are the measured directions as observed by an on-board sensor (e.g., star tracker, magnetometer, etc.).
They have no on-board sensors or electronics, and are not attitude-controlled.
In the 1970's, Safeguard's interceptors had no on-board sensors and were instead guided by radio signals from the ground.
Once the satellite had safely decelerated, Masters ordered the on-board sensors activated.
Hence control is imposed based on sensor information from on-board sensors only.
