Tightly Coupled GNSS-INS Simulation

Tightly Coupled GNSS-INS Simulation

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...

Top Military Simulating Issues

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...

Simulating Conditions on a Vessel at Sea

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,...

Challenging Jamming and Spoofing

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 Simulation: An Introduction

GNSS Simulation: An Introduction

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...
