What is the most common source of GPS interference?

• A. Signal loss
• B. Jamming
• C. Physical obstacles
• D. Device malfunction

Answer: (B)

The most common source of GPS interference is jamming. Jamming occurs when intentional signals are transmitted on the same frequency as GPS signals, disrupting the ability of GPS receivers to acquire or maintain a lock on the satellite signals. This can lead to complete loss of GPS functionality or degraded performance. Jamming can be done using various devices and techniques and poses a significant concern for military and civilian operations that rely on accurate positioning data. While signal loss, physical obstacles, and device malfunctions can also affect GPS performance, they are not as prevalent or as maliciously disruptive as jamming. Signal loss may occur due to environmental factors or inherent limitations of GPS technology, while physical obstacles like buildings or terrain can obstruct signals but aren't categorized as interference in the same active way as jamming. Device malfunction can lead to GPS errors but is generally less frequent than jamming interference. The deliberate nature of jamming makes it a unique and critical challenge for maintaining operational GPS reliability.
