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.

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.
