Fast and Furious: The Keys to High-Dynamic Positioning

Rapidly changing motion means that every aspect of positioning must be carefully re-examined and re-evaluated to avoid costly and dangerous positioning errors. The frequent changes in heading, acceleration and deceleration inherent in rockets, missiles, jet planes, race cars and other platforms — up to 100 times per second! —  dictate a very high rate of data inputs from both inertial and GNSS sensors to capture the complex trajectory.

BeiDou Conducts Laser Communication Experiment, Steps Ahead of U.S. — Could Improve SatNav Accuracy

In a race with the U.S. to develop a laser communications network in space, China’s BeiDou GNSS has conducted an inter-satellite and satellite-ground station experiment using using lasers rather than the usual radio signals. The technology could potentially transmit data a million times faster than by radio signal to almost any location. Some experts say it could increase satnav accuracy by a factor of 6 to 40

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.

ENTER LEO on the GNSS Stage: Navigation with Starlink Satellites

We are witnessing a space renaissance. Tens of thousands of broadband low Earth orbit (LEO) satellites are expected to be launched by the end of this decade. These planned megaconstellations of LEO satellites along with existing constellations will shower the Earth with a plethora of signals of opportunity, diverse in frequency and direction. These signals could be exploited for navigation in the inevitable event that GNSS signals become unavailable (e.g., in deep urban canyons, under dense foliage, during unintentional interference, and intentional jamming) or untrustworthy (e.g., undermalicious spoofing attacks).

Smartphone-based GNSS Positioning – Today and Tomorrow

This article reviews some of the recent results analyzing the feasibility of carrier-phase based positioning with smartphone data and highlights limitations largely arising due to the poor antenna quality. It shows how they might be overcome by antenna calibration or coupling to the phone’s inertial sensors. The goal is to perform a successful RTK positioning with the smartphone-quality data.
