Q: What are the key criteria in selecting a GNSS antenna for a particular application? A: Performance, size and cost. Size and cost are easy for the integrator to assess; determining the necessary antenna performance to achieve the desired system-level performance is difficult to evaluate. Obtaining the complete GNSS solution from a single source is ideal; vendors that sell both... read more
Spatial analytics company Esri has acquired technology from ClearTerra, a company that offers geospatial and activity-based intelligence tools. The acquisition will provide ArcGIS platform users the ability to easily discover and extract geographic coordinates from unstructured textual data like emails, briefings and reports, instantly generating intelligent map-based information. This capability will make mapping this elusive information easier across many industries. Defense, intelligence and... read more
u‑blox has rolled out the u-blox F9 technology platform, which was designed to deliver high-precision positioning solutions for mass market industrial and automotive applications. The platform combines multi-band GNSS technology with dead-reckoning, high-precision algorithms, and compatibility with a variety of GNSS correction data services, to achieve precision down to the centimeter level. u‑blox F9 paves the way for the next... read more
The military is always looking at new techniques and technology for deriving position and, it seems, every few years signals of opportunity (SOOP) becomes fashionable again. In broad terms, SOOP refers to the use of any signals for navigation, which are not normally intended for navigation. This might mean TV or radio broadcast signals, cellular network signals, or anything else... read more
This comment piqued my ears when heard over the coffee-break table at ION’s International Technical Meeting last month: “There is a great deal of mutual ignorance between the 5G and PNT communities. I think that the 5G people are pretty naive about PNT and the PNT community is missing an opportunity.” So when news releases leading up to next week’s... read more
Lidar and UAV technology has revealed hundreds of previously unknown Mayan ruins in the Guatemalan rainforest. In what is considered biggest aerial lidar survey in the history of archaeology, a vast and complex civilization has been discovered. The University of Houston’s National Center for Airborne Laser Mapping (NCALM) used Teledyne Optech’s Titan sensor to identify raised highways, and complex irrigation and terracing... read more
