Harxon has introduced an advanced, high-speed, Bluetooth-enabled wireless rover radio. The HX-DU1603D, designed for GNSS/RTK surveying and precise positioning, […]
Here there be dragons. That phrase (or a variation of it) was used by early mapmakers to designate […]
Current Capability and Future Promise
GPS signals are so weak, they cannot be used reliably where they are obstructed such as indoors or in concrete canyons. But if the satellites were much closer, their signals would be much stronger. The low Earth orbit Iridium constellation is already orbiting, and providing a PNT service. This month we learn about its current capability and future promise.
Applanix is collaborating on advanced research for autonomous vehicle guidance and control systems with the University of Waterloo […]
High-accuracy GNSS technology and UAV technology are hot trends — red hot. Geospatial Solutions Editor Eric Gakstatter offers a rundown on the latest GNSS, GIS and UAV technology.
The Springer Handbook of Global Navigation Satellite Systems is now available. Described as “A state-of-the-art description of GNSS […]
LTE chipset maker Altair Semiconductor has demonstrated GNSS functionality integrated in its new ALT1250 narrowband CAT-M1 and NB1 (NB-IoT) […]
Exploring imu specifications and correlating them to performance of a final product can be daunting, as differences between MEMS sensors are not always apparent. This article presents achievable performances in fusion technology across a range of IMUs among the best in their respective performance categories.
