What does M-Code mean for GPS simulation?

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,...

What Simulation Repeatability Means for Your Program

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...

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...
