Altair markets narrowband cellular chipset with integrated GNSS

June 14, 2017By

LTE chipset maker Altair Semiconductor has demonstrated GNSS functionality integrated in its new ALT1250 narrowband CAT-M1 and NB1 (NB-IoT) chipset. In addition to GNSS functionality, the ALT1250’s extreme level of integration eliminates the need for most external components required to design a cellular Internet of Things (IoT) module. Its GNSS capability was demonstrated June 13  at the Sierra Wireless Innovation Summit... read more

June 9, 2017By

Sokkia has introduced a pair of software solutions for its total stations, robotics and GNSS rover systems — GeoPro Field and GeoPro Office. GeoPro Field provides a graphical user interface designed to collect field measurements for land surveying and construction activities. “End-users needing a field tool to collect and import measurement data into design and drafting software will find GeoPro Field to... read more

Galileo provides healthy signals 97.33 percent of the time

June 5, 2017By

Europe’s Galileo satellite navigation system has undergone its first performance report since it started work at the end of last year, and it passed with flying colors, said the European Space Agency. The European GNSS Agency, GSA, through its GNSS Service Centre, has published the first of its regular quarterly performance reports on Galileo. This European GNSS (Galileo) Initial Services... read more

Google updates progress on Android GNSS measurements

May 24, 2017By

Nearly a year ago, Google debuted GPS measurements in Android. “Since then, we’ve made a lot of progress,” Steve Malkos, Google technical program manager, told GPS World. Frank van Diggelen and Mohammed Khider joined Malkos in hosting a half-day tutorial at ION GNSS+ 2016 in September that detailed how to access and use GPS measurements from Android devices. “We (Google) launched... read more

Road navigation using multiple dissimilar environmental features

May 23, 2017By

New navigation paradigms combining GNSS and inertial with additional sensors can increase overall reliability and power robust road navigation. A feasibility study tests a barometer, a magnetometer and a camera looking at road signs, and concludes that such sensors examining environmental features can supply the necessary context for frequently traveled or shared routes. read more

ESA: Space debris enters ‘more feared exponential trend’

May 23, 2017By

In April, the European Space Agency (ESA) hosted the 7th European Conference on Space Debris at ESA’s Satellite Control Centre in Darmstadt, Germany. There, international experts discussed ways to head off the threat of space junk. ESA estimates there are roughly 5,000 objects larger than 1 meter, 20,000 objects over 10 centimeters and 750,000 “flying bullets” of around one centimeter.... read more
