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...

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?

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

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...

The Challenges of Dynamic Aircraft Motion in GNSS Simulation

The Challenges of Dynamic Aircraft Motion in GNSS Simulation

Whether you are testing the integration of a navigation device or characterizing its performance envelope in the lab, the quality of your results depends on the fidelity of your GNSS simulations. Even the smallest inconsistency can send the simulated flight on a wrong...

GNSS/INS Simulations of High-Latitude Operations

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...
