Energy-Efficiency Considerations For GNSS Signal Acquisition

Future miniaturized sensors, to be used for example in bee-sized drones, mini-satellites, or wearable devices, are likely to include GNSS chipsets supporting accurate outdoor localization and also offering reduced computational costs and power consumption compared to traditional GNSS receivers. The survey various energy-efficient methods for GNSS acquisition and present a discontinuous-reception acquisition algorithm, analyzed with both simulated and measurement-based data.

Russia Explodes Own Satellite with Ground-Based Missile; Spokesperson Threatens GPS

Russia conducted an unannounced direct-ascent anti-satellite (DA-ASAT) missile test on November 15, targeting and exploding its own defunct satellite Tselina-D. After the test, Russian television executive and spokesperson Dmitry Konstantinovich Kiselyov, head of the official Russian government-owned international news agency Rossiya Segodnya, reportedly said on live tv that this demonstrated that Russia could and would if necessary target U.S. GPS satellites, thus “blinding” its military forces.

Evaluating LEO Constellations for Global Satellite Navigation Service

Low Earth Orbit (LEO) satellites are being launched regularly into space to create satellite constellations for a variety of purposes: communication, surveillance, providing Internet service and more. Global satellite navigation service is provided by satellites in higher orbits, mi-Earth orbit (MEO) roughly 25,000–27,00 kilometers above the Earth. Could satellites in LEO be used to provide global satellite navigation?

Inertial in the Field: Webinar Now Available On Demand

High standards for technology in the lab and in the factory are all very fine, but what matters most is how it works in industrial application. We take a close-up look at inertial measurement and inertial navigation in such real-world cases as
• oil and gas pipeline inspection,
• stabilization of optical camera platforms and
• autonomous cargo transport.

Washington View: PNT—Who Gets to See?

The smartphone and its various everyday apps link us to GPS, Wi-Fi networks, Bluetooth LTE, audio and cell tower proximity that help us find out where we are and tell us how to get to where we need to go, down to precise latitudes, longitudes and altitudes, accurate to within a few yards. So who should have access to this information?
