Moving GNSS/INS Testing from the Skies to the Lab

Moving GNSS/INS Testing from the Skies to the Lab

Accurate, repeatable GNSS/INS simulations let you perform integration testing in the laboratory rather than in the field. As a result, you can shift project schedules to the left and accomplish more within existing budgets. This post will explain the limitations of...
What are the Next-Generation GNSS Constellations?

What are the Next-Generation GNSS Constellations?

Global Navigation Satellite Systems (GNSS) have unleashed innovative commercial, scientific, and military applications since the US Global Positioning System (GPS) entered service in the 1980s. Today, GNSS constellations from the US, Europe, China, and Russia circle...
Space Weather and GPS Operations

Space Weather and GPS Operations

The Sun’s atmosphere and magnetosphere extend far beyond Neptune’s orbit, leaving Earth orbiting through a cloud of plasma that constantly interacts with our planet. In extreme conditions, space weather makes GPS reception less reliable and can impact industrial...
GNSS from Low Earth Orbit: Where Are We in 2022?

GNSS from Low Earth Orbit: Where Are We in 2022?

In the nearly three decades since America’s Global Positioning System became fully operational, three more GNSS constellations have entered service. Comprising dozens of satellites in Medium Earth Orbit (MEO) or higher, these constellations provide global positioning...
GNSS Simulation and Dynamic Motion at Sea

GNSS Simulation and Dynamic Motion at Sea

Getting accurate, repeatable results from GNSS simulations depends on faithfully reproducing the simulated vehicle’s motion. Last month we explored the variables impacting aircraft simulations. This month, we will look at how GPS reception depends on the design and...
