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.
