Out in Front: Yes, We Have No Bananas

February 1, 2015By

What if the U.S. government stepped in and confiscated all your bananas? Grown foreignly, they lack proper accreditation to enter this country. That they have done so for years is no excuse. They are illegal. Those who consume said bananas engage in unlawful activity. Those who facilitate such consumption — you, in this case, whom we imagine to be a... read more

2, 4, 6, 8 — Who Do We Appreciate?

January 29, 2015By

Galileo, that’s who! For dogged determination and persistent pushing-forwardness in the face of adversity, obstacles, and the occasional technical difficulty. That there may be occasional confusion, as well, or mixed messages as to just what the future may bring, is certainly understandable. In fact, it is to be expected, given the circumstances. Let’s review the math. Two Two for the... read more

Self-Driving Cars Find Their Way at CES

January 21, 2015By

This year’s CES featured the usual big TV screens, loudspeakers, wearables, 3D printers, drones and connected vehicles surrounded by 150,000 attendees over several Las Vegas meeting venues. What was interesting was the continued rise of autonomous, or self-driving, vehicles and platforms. Lost in all of the noise was a small, but important, location-based services enclave that consisted of GPS-enabled wearables and indoor positioning. read more

Automakers No Longer the Neanderthals of Tech

In the wake of CES and the North American International Auto Show in Detroit, it’s clear that times are a-changing. Self-driving concept cars filled three football-field-sized areas to show off what lies ahead. Verizon and Ford did a cosmic switcheroo, with Verizon morphing into the auto space and Ford starting a transformation into a mobility company. Automated reality/augmented reality isn’t... read more

Expert Advice: Loose Coupling — And What’s Wrong With It

January 2, 2015By

Concerns raised about cascaded Kalman filters for loose coupling and/or usage of input data “massaged” in unknown ways are not new, but are routinely excused by requirements to use coordinates from receivers not providing measurement outputs. Often, however, a receiver’s internal 8-state extended Kalman filter (EKF) is not fed with precise carrier phase data — and even when it is, its velocity outputs (being both filtered and unaided) have limited ability to follow high dynamics. Velocity pseudomeasurements under those conditions interfere with IMU aiding. read more

Out in Front: All-Day, Everywhere for All

January 1, 2015By

We appear incompletely before you this month. A funny thing happened on the way to the presses: we discovered that we had more content than pages in which to squeeze it. “All the news that fits to print,” the motto of the New York Times, can in this instance not be ours. All the news just won’t fit! First to... read more
