Method for direction limitation and system for direction limitation

A direction limitation system for a firing system, comprising:

• at least one sensor configured to measure an elevation of the firing system,
• at least one sensor configured to measure a traverse of the firing system,
• a first calculating unit which controls the firing system, wherein the first calculating unit calculates a position of the firing system based on the measured traverse and elevation, and wherein a first set of direction limitation positions is known by the first calculating unit, wherein the first calculating unit compares the position of the firing system with the first set of direction limitation positions and prevents movement of the firing system when the position of the firing system is outside the first set of direction limitation positions, and
• a second calculating unit configured to measure traverse and elevation, and compare the position of the firing system with a second set of direction limitation positions.

A firing system, comprising:

• a direction limitation system comprising
• at least one sensor configured to measure an elevation of the firing system,
• at least one sensor configured to measure a traverse of the firing system,
• a first calculating unit which controls the firing system, wherein the first calculating unit calculates a position of the firing system based on the measured traverse and elevation, and wherein a first set of direction limitation positions is known by the first calculating unit, wherein the first calculating unit the position of the firing system with the first set of direction limitation positions and prevents movement of the firing system when the position of the firing system is outside the first set of direction limitation positions, and
• a second calculating unit configured to measure traverse and elevation, and compare the position of the firing system with a second set of direction limitation positions.

A craft, comprising:

• a firing system comprising a direction limitation system comprising
• at least one sensor configured to measure an elevation of the firing system,
