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

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.

Today, the President accepted the recommendation of the Department of Defense to end procurement of Global Positioning System (GPS) satellites that have the capability to intentionally degrade the ...

The U.S. Space Force has reassigned another GPS satellite launch from United Launch Alliance to SpaceX, marking the fourth ...

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

Global Navigation Satellite Systems (GNSS) underpin modern positioning and navigation, integrating signals from multiple satellite constellations such as GPS, GLONASS, Galileo and BeiDou. Recent ...

With the rapid development of GPS (Global Positioning System) techniques, GPS gets wider application in many fields. GPS has features such as high precision, global coverage, convenience, high quality ...

Abstract: GPS has evolved into a vital component of our critical infrastructure. Originally developed over 50 years ago as a military navigation system, it has since been transformed into an ...

Increasing incidents of interference with aviation, maritime and other satellite telecommunications services mean States need to urgently enhance their protection of a critical radio-frequency band, ...

provide some protection against interfering signals. Although quantitative measures of resistance to RF interference, such as jammer-to-signal ratio (J/S) measured in decibels (dB) do exist, these ...

Global Navigation Satellite System (GNSS) positioning techniques have evolved significantly over recent decades, spanning from traditional single-frequency methods to advanced multi-constellation and ...

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 ...
