Galileo Initial Services looming

September 26, 2016By

With Galileo Initial Services at last on the horizon and a quadruple satellite launch scheduled for November, here’s hoping that Europe’s GNSS constellation will be delivering limited, but reliable, global PNT services before the year is out. The four Galileo satellites for Arianespace’s first Ariane 5 mission for the constellation are being prepared at ESA’s launch facility in French Guiana.... read more

5G and IoT: Big winners of CTIA Super Mobility 2016

September 12, 2016By

This year’s CTIA Super Mobility show, held Sept. 7-9 in Las Vegas, Nevada, shone the spotlight most brightly on 5G and the Internet of Things (IoT). The killer app use case for 5G is IoT and, symbiotically, IoT cannot be fully realized without the higher capacity of 5G. IoT is the world of interconnected devices and includes smart cities, connected... read more

GNSS coordinates as survey evidence — friend or foe?

September 7, 2016By
First-order horizontal monument, U.S. Coast and Geodetic Survey, 1931.

In my last column in July, I shared the situation with U.S. federal lands in Alaska being surveyed with GNSS and subdivided by coordinates, instead of subdivided by traditional methods of setting monuments. The topic drew a varied range of responses and opinions. While some felt the article was on point with setting bad precedents, others added that it was time for technology... read more

GNSS, radars assist in all-weather vehicle positioning

September 6, 2016By

Everyone talks about the weather, but nobody does anything about it — right? Our lead authors this month are doing something about it. The July cover story of GPS World magazine was titled “See into the Smoke with Inertial.” This month’s feature could have been called “See into the Fog with CDGNSS,” but we just didn’t have room in the... read more

Expert Opinions: Buyers’ need for GNSS receiver testing, certification

August 29, 2016By

Q: Buyers get little guidance as to how specific receivers react to interference, particularly in critical infrastructure. Is there a need for receiver testing and certification along the lines of Underwriters Laboratories to guide purchase and acquisition? A: Exhaustive “seven-nines” testing and verification is expensive, takes a long time and stymies innovation. Yet simple and pragmatic testing can reveal faults... read more
