GPS is the gold-standard for the provision of Positioning, Navigation, and Timing (PNT). When GPS/GNSS is available and trustworthy, you should use it. What do you do when it’s not available or not trustworthy? As the global market leader in continent-wide Complementary PNT solutions, we have developed high-power, Low-Frequency (LF), ground wave technology that is the most reliable, scalable, and future-proof available. Besides PNT, we can also provide phase, frequency, and azimuth, and even 3rd-Party Data Channel solutions. Our technology is fully interoperable with, yet completely independent of, GPS/GNSS. We offer “sky-free” PNT directly to users, or as an enabler of other technologies.
