What is a disadvantage of satellite guidance systems?

Satellite guidance systems do have a significant disadvantage in that they rely on signals which can be susceptible to jamming or destruction. This vulnerability stems from the fact that signals transmitted from satellites to receivers can be disrupted by various forms of electronic interference, both intentional and unintentional. Jamming can occur from adversarial forces attempting to confuse or mislead guidance systems, whereas destruction of satellite signals may result from kinetic anti-satellite operations or natural phenomena that affect the satellite's operation. This dependency on signal integrity is critical, as compromised signals can result in lost positional accuracy or complete system failure, thereby impacting the effectiveness of operations that rely on precise navigation and targeting.
