NASA’s laser retroreflector arrays aboard GPS III satellites enhance positioning accuracy for Earth navigation and scientific measurements by reflecting laser signals back to ground stations.

Definition The Global Positioning System (GPS) uses a network of satellites to provide electronic signals that enable a receiver to accurately determine its position anywhere on Earth. The satellites ...

computer software converts it into information that can be usefully displayed for a user, such as position coordinates, or input to another type of user equipment, such as an inertial navigation ...

The pilots flying into Denver International Airport could tell something was wrong. In urgent calls to air traffic controllers, they reported that the Global Positioning System they used to navigate ...

GPS is the best technology for tracking the location and movement of any object anywhere in the world. GPS stands for “Global Positioning System,” and refers to a worldwide network of satellites, ...

A new study investigates how “flex power”, a technology that dynamically redistributes satellite signal power to resist interference, affects positioning accuracy and navigation reliability.

Basic GPS is enough if you are just looking for simple tracking. However, if you require visibility from more than one vehicle, driver, or job, then automated vehicle location usually is the more ...

The global positioning system (GPS) capabilities of cargo ships, oil tankers and other vessels stuck in the Middle East because of the widening war are likely worse than those in your cell phone.

The war with Iran is laying bare the dangers posed to commercial ships and planes by the rise of GPS interference in and around conflict zones.

GPS spoofing and signal jamming are disrupting ships near conflict zones like Iran. Here’s how cyber interference is confusing global navigation systems.
