When I think of “significant” advancements in GPS navigation, I think of things like the implementation of ADS-B or LPV and RNAV approaches. Those predate 2020 and I found it difficult to pinpoint substantial advances in the last 3 years. I have compiled a 5-point list from what I found, you may recognize a few from our assigned reading.
Current ongoing project and ageing satellite updates: The satellites in use today for GPS navigation use a signal that was originally placed into use in 2005 and is called “L2C”. “The satellite modernization program dubbed as the GPS 3 (or Block III), and its sequel GPS 3F (Follow On), will replace the legacy GPS spacecrafts with up to 32 new satellites. These new satellites will not only have a longer operational lifespan of 15 years, but they will also carry payloads that have more advanced satnav signaling technologies. Aerospace company Lockheed Martin is manufacturing the new satellites, 10 of which are already built” (Delgado, 2024). The new signal will be called “L1C” and will provide three times better signal accuracy and “up to eight times improved anti-jamming capabilities” (Delgado, 2024).
January 2021: “U.S. Space Policy Directive 7 issued. The first update to U.S. policy on space-based position, navigation and timing (PNT) in more than 16 years, SPD-7 directs the pursuit of multiple and varied sources of PNT and increased cybersecurity for GPS, and it acknowledges the potential for GPS to contribute to in-space applications” (Warwick, 2023).
June 17, 2021: “For GPS III, after the successful launch of Space Vehicle 5 (SV05) on June 17, 2021, it was set healthy (usable) on May 25, 2022. The significance of SV05 is its full operational capability of the improved civilian L2 (L2C) signal. L2C improves service speed for commercial users via access to two frequencies, improves accuracy when combined with legacy civil GPS signals (L1 C/A), and is less susceptible to ionospheric interference” (Dunn, 2023).
January 18, 2023: “On Jan. 18, 2023, SV06 successfully launched into orbit aboard a SpaceX Falcon 9 Block 5 rocket from Cape Canaveral Space Force Station, Florida. The launch of SV06 marks a key step in the larger goal of modernizing the GPS constellation. Additionally, the 10th and final satellite in the GPS III fleet finalized production and has a target launch date of 2026. GPS III Space Vehicles 7–10 are in storage and available for launch” (Dunn, 2023).
2024: “First next-generation Galileo launch: The European Space Agency in 2021 signed two contracts with Airbus Defense and Space in Germany and Thales Alenia Space in Italy to design two independent families of more accurate, secure and flexible Galileo Second-Generation (G2) satellites and build six each for launch beginning in 2024” (Warwick, 2023).
GPS is a constantly evolving technology. Several advancements in recent years have increased its accuracy, reliability, and security. These advancements have increased operational efficiency and addressed safety concerns in aviation.
GPS III became useable in May of 2022. GPS III improved signal quality for civilian use, also known as L2C. This provided two frequencies that improved speed and accuracy. GPS III also provided a military signal (M-Code) that includes worldwide coverage. M code GPS also provides improved defense against GPS jamming and spoofing. This was a big problem on the aircraft I worked on in the middle east. This created problems with the TCAS systems, giving erroneous TA/RA advisories out of nowhere.
GPS IIIF was a further improvement to the GPS III. Some of its enhancements over GPS III were improved signals to aid in search and rescue operations. It had more precise ranging capabilities. Further improvements were made to the military side to combat jamming. Regional Military Protection (RMP) added about 60 times greater protection against jamming. The improved signal structure allows for better performance under challenging environments, making it a significant advancement for aviation safety and efficiency.
The Next Generation Operational Control System (OCX) is another advancement that was put in place in March of 2022. This modernized control system increases cyber security to the latest Department of Defense standards. Jamming has become a major problem in recent years, and this is one of the many steps taking to minimize that. This system provides a more secure and reliable GPS operations for both Civilian and Military aviation.
Modern GPS User Equipment (MGUE) is a program focused on developing receivers that can use all of the M-Code GPS signal’s capabilities. The pattern in these improvements points back to combatting jamming and spoofing. There appear to be provisions to launch a jamming and spoofing attack of our own that won’t affect our GPS signal. Although this programming doesn’t initially appear to be civilian aviation related. As with all things military, it will eventually make it to the civilian side of things, except for the outgoing jamming, which we are probably not going to see as a civilian.
Several improvements have been made to accuracy and argumentation technology. Advancements have been made in ground-based augmentation systems. Real-time Kinematic (RTK) and Precise Point Positioning (PPP) have significantly improved GPS accuracy. These technologies are essential for precise aviation navigation and operations, especially in environments where high accuracy is critical.
Isaiah 43:19 Talks about God’s power to create pathways and provide resources in seemingly impossible situations. In the context of GPS advancements for aviation, we can see parallels in the idea of making “a way in the wilderness.” GPS technology significantly enhances navigation and safety, allowing pilots to traverse vast and challenging environments precisely and confidently.
