CAST Navigation GNSS/INS simulators shrink the world to the size of your lab. We let you recreate GNSS conditions anywhere on Earth at any point in time and then model reception by any vehicle. However, developing scenarios that replace field testing requires taking...
CAST Navigation will attend the biennial Position Location and Navigation Symposium (PLANS) from April 24-27 in Monterey, California. PLANS provides the international navigation community with a forum for learning about the latest navigation and positioning technology...
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...
CAST Navigation will exhibit at this year’s ION International Technical Meeting, being held January 23-26 in Long Beach, California. Visit us at Booth 4 between ITM to learn more about our simulation capabilities With over four decade’s experience, CAST Navigation has...
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...
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...
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...
A vehicle’s design and its GNSS/INS implementation can have an influence on reception and navigation performance — especially in high-dynamic motion scenarios. Previously, we looked at the simulation implications for vehicles in flight as well as vessels at sea. In...
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...
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...
