ARE WE THERE? In a multi-GNSS world, that is. We’ve asked that question from time to time in this column over the years. So, are we there yet? That depends. One definition of “multi” is more than one.

Multi-frequency-region parallel sensing (MFRPS) is poised to enable larger-sized, thinner, and more responsive touchscreens.

SINGLE-FREQUENCY GPS POSITIONING. Can it get any better? In the March 2018 edition of this column, we looked at the development of precise point positioning or PPP — the (mostly) carrier-phase-based ...

Switches controlled by the input signal amplitude are used as input signal level indicators, input signal level analyzers, power supply voltage indicators, and so on. Such switches are usually made as ...

Benefiting from the high-speed optoelectronic response and submicrometer positional accuracy of the TD-PSD, the team realized multi-target real-time trajectory tracking with a maximum image output ...
