Warming oceans are making the Arctic more navigable. This creates opportunities for shipping, fishing, and other industries. A warmer Arctic also becomes more strategically competitive. Over the past two years, every American military service has updated its Arctic...

GPS military codes ensure that America’s armed forces receive the most accurate and precise positioning information anywhere in the world at any time. Delivering that performance consistently and reliably requires extensive testing during receiver development,...

In the physical world, GPS signals and radio frequency (RF) interference are naturally coherent. In simulations, every effect at every instance of simulated time must be calculated separately. Synchronizing and combining these calculations to generate coherent GPS and...

Why Simulation Repeatability Matters Given the same initial conditions, GNSS/INS simulations of the same mission scenario should produce the same result every time. Different results indicate a problem with the receiver. Or do they? Poor simulation repeatability can...

Global navigation satellite systems (GNSS) and inertial navigation systems (INS) are naturally complementing positioning and navigation technologies, because each one compensates for the other’s deficiencies. Therefore, as demand for reliable positioning and...

A recent article in IEEE Spectrum revealed and detailed a very alarming threat to airline safety posed by GPS tests conducted by the U.S. military. According to the article, military tests that jam GPS signals to test military defenses against such jamming are an...

For many applications, in addition to knowing a platform’s position it is nearly as important to know its attitude, which consists of three rotational components—roll, pitch, and yaw—and three linear ones—heave, surge, and sway. For example: for aerial photogrammetry,...

Simulators assist GNSS receiver manufacturers and integrators in testing their devices against realistic scenarios that include both ideal and suboptimal conditions. It is particularly important to be able to test against simulated jamming and spoofing, which are...

GNSS simulators enable manufacturers and integrators of GNSS receivers to safely and efficiently test the systems into which they are integrating under a wide range of scenarios and solve problems before they affect the performance of live systems. Global navigation...
