Understanding GPS Interference

GPS interference can be broadly categorized into two types: intentional and unintentional. Both pose significant challenges to maintaining the integrity of GPS signals.

Intentional Interference

Intentional interference, often referred to as jamming, involves the deliberate broadcasting of signals that overwhelm GPS frequencies. This can be employed by adversaries in military contexts to disrupt operations, as noted by AVBrief.

Unintentional Interference

Unintentional interference can result from a variety of sources, including atmospheric conditions, faulty electronic equipment, and even other communication systems. These sources can degrade signal quality and lead to inaccuracies, as highlighted in Inside GNSS.

The Impact of Interference

Interference can have severe consequences, particularly in critical applications. Inaccurate GPS data can misguide military operations or disrupt financial systems, leading to cascading effects across sectors, as reported by Better World Campaign.
