hamburg-messe-intergeo

Last year at InterGeo 2015, UAVs ruled, for at least the second year in a row, although some of its newest-thing gloss seemed to be wearing off. This year, sensor integration in both hardware and software is a dominant theme — and one with broader implications and applications. GNSS positioning technology, aided in many cases by laser scanning, other imaging... read more

Innovation: Evolutionary and revolutionary

FIGURE 1.  An extended bandwidth GNSS antenna. The lower and connected dipoles are tuned to L2 and the upper coupled shorted dipoles are tuned to L1. Current flow in the circular waveguide of the GNSS antenna is shown. Strong circumferential currents flow at the top of the waveguide. Red indicates large currents and the arrows show the directions of the current flow.

The development and performance of the VeraPhase GNSS antenna
We take a look at a revolutionary design of a multi-frequency multi-GNSS antenna. Our authors discuss how the antenna evolved from a research project in academia to a commercial product about to enter the market. read more
