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...
A recent article in IEEE Spectrum revealed and detailed a very alarming threat to airline safety posed by GPS tests conducted by the U.S. military. According to the article, military tests that jam GPS signals to test military defenses against such jamming are an...
For many applications, in addition to knowing a platform’s position it is nearly as important to know its attitude, which consists of three rotational components—roll, pitch, and yaw—and three linear ones—heave, surge, and sway. For example: for aerial photogrammetry,...
Simulators assist GNSS receiver manufacturers and integrators in testing their devices against realistic scenarios that include both ideal and suboptimal conditions. It is particularly important to be able to test against simulated jamming and spoofing, which are...
GNSS simulators enable manufacturers and integrators of GNSS receivers to safely and efficiently test the systems into which they are integrating under a wide range of scenarios and solve problems before they affect the performance of live systems. Global navigation...
The power of avionics technology has brought us to measuring distance in micrometers and pinpointing areas anywhere on the globe. With the latest in cutting-edge GNSS receivers, getting from point A to point B is the beginning. To get to grips with this potent...
If you pay attention to the news, you’ve probably heard a lot in the last few years about military drone strikes. These started in the Bush era, but they doubled during the Obama administration and today are an integral part of our military efforts overseas. But do...
The smartphone revolution happening across the globe means people are increasingly reliant on global technology networks. Data centers and connected devices store personal documents, photo libraries, and other personal data. They are also responsible for keeping track...
From searching the nearby location of hardware stores on your smartphone to the map app your Uber driver uses, the Global Positioning System (GPS) acts as your modern guide to reach your destination. While GPS is mainly used in transportation, it also helps other...
Passenger safety is one of the biggest concerns with autonomous vehicles. Just last year, an experimental autonomous Uber car fatally struck a pedestrian in Arizona. In an effort to decrease the potentially fatal risks of operating a self-driving vehicle, both for the...
