GPS is a nifty piece of technology. GPS hardware needs to have a clear view of the sky because it's satellite based, so using your handheld unit can be a problem when the roof of your car is blocking ...

GPS can be a bit complex of a technology – you have to receive a signal below the noise floor, do quite a bit of math that relies on the theory of relativity, and, adding insult to injury, you also ...

Advanced Navigation has released Spatial Dual, its new dual-antenna GNSS/INS. Spatial Dual is a ruggedized miniature GPS-aided inertial navigation system and AHRS that provides accurate position, ...

Abstract: A compact, single- feed, dual band, circularly polarized annular ring patch antenna coupled to a cross slot is proposed in this letter for GPS-aided GEO-augmented navigation (GAGAN) ...

Poor coherence between simulated GNSS and inertial signals introduces subtle errors in EGI navigation system outputs and can create misleading test results. Understanding why it’s important for a ...
