Introduction
Nowadays, Global Positioning System (GPS) is a common and popular navigational instrument implemented in many fields of human life. For instance, it can be highly effective in aviation and aerospace navigation due to its efficiency in terms of aircraft positioning. However, GPS users in the United States can often confront various issues, such as spoofing. The system might require additional hardware to operate efficiently, including means of detection.
Global Positioning System in the United States
The goals of aviation in the 21st century have caused a necessity to create an effective method of aircraft positioning. GPS is one of many instruments implemented in the satellite technology of the Global Navigation Satellite Systems (GPSS) (Krasuski & Savchuk, 2020). However, not all of them are certified to be used for general purposes in civil aviation. GPS is one of two such systems that have received certifications based on various efficiency parameters, including accuracy, availability, continuity, and reliability (Krasuski & Savchuk, 2020). The primary reason is the dangers associated with navigational systems, especially their potential vulnerability to multiple interferences on radio frequencies. Some of them are unintentional, like signals coming from TV or radio stations, but others are intentional, like spoofing attacks or jamming (Miralles et al., 2020). Nowadays, researchers and scientists recommend different detection methods, such as power monitoring metrics, to provide the most effective spoofing detection algorithm (Miralles et al., 2020). GPS becomes a highly efficient navigational tool with some assistance from additional hardware.
Conclusion
Overall, GPS in the United States requires additional means of detection to be able to deal with issues like spoofing and keep its effectiveness. GPS is one of the most common global navigational systems, especially in aviation and aerospace navigation. Given that it has its own tools to address potential problems, GPS can significantly help aircraft and people working with them.
