The Federal Communications Fee (FCC) has initiated a continuing to discover industrial applied sciences that might complement the International Positioning System (GPS), acknowledging the know-how’s vulnerability to disruption regardless of its essential function in America’s financial and nationwide safety infrastructure.
FCC Seeks to Deal with GPS Vulnerabilities
The FCC introduced at this time (March 27, 2025) that it has launched an inquiry to discover industrial applied sciences that might complement the International Positioning System. The initiative is available in response to issues that GPS represents “a single level of failure that may be susceptible to disruption or manipulation by our adversaries.”
The Discover of Inquiry (FCC 25-20) examines how the Fee may foster GPS enhances and options, in search of feedback on a variety of Place, Navigation, and Timing (PNT) applied sciences being developed by broadcasters, wi-fi operators, satellite tv for pc constellations, and startups utilizing FCC-licensed spectrum. The Fee can be requesting suggestions on the tradeoffs amongst these rising PNT choices.
GPS: The Basis of Trendy Drone Know-how
The FCC’s exploration of GPS options comes at a time when the know-how has confirmed invaluable to quite a few industries, significantly drone growth. Over the previous 15 years, GPS has remodeled drones from complicated machines requiring important piloting ability to accessible instruments for each professionals and shoppers.

GPS know-how revolutionized drone flight by enabling exact place holding, computerized stabilization in wind, return-to-home security options, waypoint navigation, and altitude locking. These capabilities dramatically simplified drone operation in comparison with conventional RC plane, which require fixed handbook changes to take care of stability.
Earlier than GPS integration, sustaining a gentle hover with a drone was extraordinarily difficult. The know-how’s potential to supply exact positioning knowledge permits drones to robotically modify motor speeds to take care of place even in altering circumstances, releasing pilots to deal with digital camera management quite than fundamental flight mechanics.
Frank Wang’s DJI: Pioneering GPS Integration in Client Drones
Frank Wang, who based DJI in 2006 whereas learning on the Hong Kong College of Science and Know-how, performed a pivotal function on this transformation. The corporate’s launch of the Phantom drone sequence in 2013 represented a watershed second for client drones, making them considerably extra user-friendly than another drone in the marketplace at the moment.
By integrating GPS know-how with clever flight controllers, DJI’s improvements dramatically expanded the market past conventional RC fans. The corporate’s deal with accessibility introduced drones from primarily navy functions into client fingers, successfully launching the patron drone market. By 2020, DJI held practically 77% of the US market share for client drones.
Present GPS Options in Improvement
Whereas GPS has been foundational for drone growth, a number of options are already in use or beneath growth globally:
GLONASS, Russia‘s International Navigation Satellite tv for pc System, consists of 24 satellites in center round orbit and is especially fitted to use in excessive latitudes the place GPS alerts will be problematic. It offers real-time place and velocity dedication for each navy and civilian customers.
China‘s BeiDou Navigation Satellite tv for pc System (BDS) grew to become totally operational in July 2020 and now offers international protection with 35 satellites in varied orbits. BeiDou provides a singular brief message communication service, permitting customers to ship and obtain textual content messages of as much as 120 Chinese language characters.
Past these satellite-based methods, rising options embody Enhanced Lengthy-Vary Navigation (eLORAN), a terrestrial beacon system extra proof against jamming than GPS, and SuperGPS, a ground-based various utilizing atomic clock time alerts distributed by way of fiber optics that has demonstrated accuracy of 10 centimeters in city environments.
For drones particularly, sensor-based options are more and more necessary, together with Inertial Navigation Techniques (INS), vision-aided navigation utilizing cameras and laptop imaginative and prescient algorithms, and LiDAR-based navigation for creating 3D maps of the surroundings.
Potential Impression on Drone Operations
The FCC notes that PNT knowledge “is integral to numerous navy, public security, agricultural, and industrial actions.” For the Drone Business particularly, which has develop into closely reliant on GPS know-how, the event of sturdy options may guarantee continued operations even in GPS-denied environments.
Scientific Techniques has already demonstrated non-GPS, image-based precision navigation software program for flight operations starting from 25,000 toes right down to 200 toes. Many of those various applied sciences are being developed to work collectively, creating layered, resilient navigation methods that may function successfully in various circumstances the place GPS is perhaps unavailable or unreliable.
The Path Ahead
The Fee intends to construct a complete document on actions it could take to strengthen GPS and promote different PNT applied sciences. These actions may embody FCC rule adjustments, public-private partnerships, testbeds, Innovation Zones, and extra.
For an business that has benefited tremendously from GPS know-how, the event of complementary and various navigation methods represents each a problem and a chance. As drones proceed to evolve for functions starting from supply providers to important infrastructure inspection, resilient positioning know-how will stay important for his or her protected and dependable operation.
