Which statement best describes the handling of GPS loss during sUAS operations?

• A. Continue mission as planned
• B. Reconfigure to operate without GPS
• C. Cookie-cutter approach: Use manual control only
• D. Follow normal sUAS operational procedures, noting GPS mode changes

Answer: (D)

When GPS data isn’t available, the aircraft can no longer rely on GPS-based position hold and navigation. The important thing is to follow the standard operating procedures for GPS loss and be ready for the flight controller to switch to a non-GPS mode. You’d monitor the GPS signal and the current flight mode, maintain control with your inputs, and adapt the mission plan as the situation dictates—this might mean continuing in a non-GPS mode if it’s safe, or transitioning to a safe landing or alternative plan per SOPs. This approach keeps you aligned with established safety practices and ensures you respond appropriately to the loss of GPS. Jumping back into the mission as if nothing changed, trying to operate without adjusting, or using a one-size-fits-all manual approach doesn’t account for how the aircraft behaves when GPS is unavailable.
