In today’s high-tech battlefield, even the most advanced systems are vulnerable. One of the most pressing threats in modern urban combat simulations is GPS spoofing—where adversaries jam or falsify GPS signals, causing drones and units to veer off-course. This results in navigation failures, misaligned operations, and dangerous confusion on the ground. The Navigating Without GPS: AP Precalculus in Urban Combat Simulations project presents a powerful solution by transforming these real-world de
