Engineers are monitoring in real time the effects on Casablanca’s aging buildings during tunnel construction using a Spectra Precision GNSS receiver. Vibrations during the construction of a new 1,890-meter tunnel adjacent to Casablanca’s Old Medina, the 250-year-old section of the famed Moroccan city, challenged the stability of its historically important buildings. To monitor in real time the effects on the... read more
Users can now install and test Touch GIS, a mobile field data mapping app, for as long as needed with a free license tier. Previously, users were able to install the app and sign up for a 14-day free trial period. “We realized some users needed more time to evaluate the many features of Touch GIS,” said Joe Wilson, head... read more
The 6th Satellite-Based Augmentation Systems Interoperability Working Group (SBAS IWG) took place Feb. 5-7 in Delhi, India. During the meeting, SBAS developers and operators were joined by users of the systems, with representatives of airlines, aircraft makers and avionics manufacturers. About 50 people in total attended the meeting. “Satellite-based augmentation systems deliver the necessary accuracy, integrity, availability and service continuity... read more
Using data from GPS receivers and seismographs, three seismologists may have found a way to identify tsunami earthquakes in time to warn people A few times a century, a medium-sized earthquake causes a large and devastating tsunami. The most recent occurrence was in 2010, when a magnitude 7.8 earthquake off the Mentawai Islands in Indonesia set off a tsunami that... read more
GNSS, coupled with inertial systems and software, is enabling greater accuracy in construction and agriculture. Other markets using machine control include unmanned vehicles, mining, surveying, mapping and defense. At construction sites, GNSS receivers can be found in heavy equipment such as bulldozers, excavators, graders and pavers. On farms and in orchards, GNSS increases productivity of machines ranging from tractors to... read more
GPS World spoke with Guillermo Perez-Iturbe, Trimble’s marketing director – agriculture, about the challenges for farms in adopting precision agriculture, including time, cost and connectivity issues in rural areas. What technical challenges are faced in applying GNSS? GNSS technology is at the center of precision agriculture and is one of the key enablers for the farm of the future. GNSS... read more
Precision agriculture — the practice of optimizing inputs of seed, water, and fertilizers while maximizing yields by mapping variations in soil characteristics and guiding machinery accordingly — began in the United States in the early 1980s and has been growing steadily. Key components include soil mapping based on sampling and remote sensing, proximal sensing of soils and crops, variable rate... read more
Septentrio has added to its integrated GPS/GNSS receiver portfolio with the AsteRx SB ProDirect, which delivers reliable high-accuracy positioning for machine navigation and control in challenging environments. The AsteRx SB ProDirect dual-antenna receiver is designed as an “install-and-forget” device to provide continuous positioning for demanding industrial applications, Septentrio said. It gives machines and robotics access to heading and pitch or... read more
