Every month, we ask members of our Editorial Advisory Board to weigh in on a topic. For the January 2021 issue, we asked, Will precise point positioning (PPP) replace real-time kinematic (RTK)? If so, for which applications and when? “Recently, Hexagon’s Autonomy & Positioning division demonstrated RTK levels of performance — globally —through PPP technology; we call it RTK From... read more
Antenna development, going all the way back to the first antennas, has been one of continuous innovation,” Richard Langley wrote in our September issue. Even after more than 30 years of GNSS technology development, he pointed out, GNSS antenna development continues. His statement is borne out by the responses submitted by manufacturers of GNSS antennas to four questions we posed... read more
TCarta Marine has introduced a Global Satellite Derived Bathymetry (G-SDB) product line developed with a new seafloor depth measurement technique that leverages Machine Learning and NASA ICESat-2 laser data. According to the company, this G-SDB offering covers the entire Red Sea, with additional sets rolled out through the end of this year. The commercial TCarta G-SDB data sets and the... read more
By San Gunawardana, Guest Author Advances in geospatial technology have opened up many new possibilities in areas such as national security, urban planning and emergency preparedness. When I was embedded with the U.S. Army as a scientist in Afghanistan, I got to experience firsthand the exceptional value of 3D data. The military used nation-scale imagery and lidar to generate 3D... read more
GNSS Winter School 2021 is planned for Feb. 22-26 in Islamabad, Pakistan. The Institute of Space Technology is hosting the event, in collaboration with the Space Education Research Lab of the National Center of GIS and Space Applications. GNSS Winter School will be held on the institute’s campus; however, in case of severe circumstances (such as COVID-19), it will take... read more
STMicroelectronics’ latest RF front-end for GNSS receivers offers a simplified design and smaller footprint. The BPF8089-01SC6 integrates the impedance-matching and electrostatic discharge (ESD) protection circuitry typically implemented using discrete components. The BPF8089-01SC6 provides a 50-ohm matched interface between the receiver’s antenna and low-noise amplifier (LNA), and is ready for plug-and-play with the company’s STA8089 and STA8090 LNAs. The BPF8089-01SC6 is... read more
James D. Litton, GPS pioneer and founder of NavCom Technology Inc., died over the weekend at his home in California with his family at his side. He was 89 years old. Litton was an early contributor to the development of GPS user equipment. He also played a pivotal role in the GPS-driven transformation of global agriculture that has greatly benefited... read more
