What is a planning factor for using Excalibur rounds?

The use of Excalibur rounds, which are guided artillery projectiles, requires careful consideration of specific planning factors to ensure optimal performance. Deploying the rounds with a high angle is crucial for GPS acquisition because this firing method enhances their accuracy and guidance capabilities. When fired at higher angles, the projectile can achieve a better trajectory that maximizes the effectiveness of its GPS system, allowing for a more precise strike on the target. The guidance system relies on receiving signals from satellites, which can be improved with higher elevation releases, reducing the chance of losing signal during flight.

The other choices do not align with the specialized nature of Excalibur rounds. The first option suggests deploying at low angles, which is less effective for GPS acquisition, while the standard aim points route does not account for the necessary adjustments that guided munitions require for precision targeting. Engaging moving targets only does not specifically relate to the ballistic characteristics or planning factors that optimize the performance of Excalibur rounds. Therefore, high-angle firing for GPS acquisition stands out as the appropriate planning factor for these guided munitions.
