In the case of crisis and disaster situations, Public Safety Organization (PSO) experience situations where most of the telecommunication infrastructure becomes unavailable or not reliable. Thus, an effective disaster assessment of the situation becomes a challenging task for the PSO. UAV is considered as the most suitable solution to address these scenarios where a maximal radio coverage of the target area is crucial. In this work, a square area is considered which mathematical approximation to ensure a maximal coverage based on “covering a square with equal circles” is investigated. The proposed approach outperforms the existing ones as it reduces effectively the total difference delay time to cover the target area. Furthermore, it allows time-saving to achieve more stops at the target area compared to existing schemes leading to better PSO activity performance.

在危机和灾难情况下，公共安全组织（PSO）会遇到大多数电信基础设施变得不可用或不可靠的情况。因此，对情况进行有效的灾难评估成为PSO的一项艰巨任务。无人机被认为是解决这些情况的最合适解决方案，在这些情况下，目标区域的最大无线电覆盖范围至关重要。在这项工作中，研究了一个正方形区域，该区域基于数学上的近似以确保基于“用相等的圆覆盖正方形”来确保最大的覆盖率。所提出的方法优于现有方法，因为它有效地减少了覆盖目标区域的总差延迟时间。此外，
