Tiny coprocessor delivers step-by-step tracking without GPS

According to the company, the device does so at about one tenth the power consumption of global positioning systems (GPS). The SENtrace unit is a 32-bit processor with a custom floating-point unit embedded with PNI’s sensor fusion tracking algorithms.

The unit measures 1.7 x 1.7 x 0.5 mm and is accurate down to about the nearest meter in every 100 meters travelled, the company claims. The processor is a 32-bit ARC processor licensed from Synopsys. In the past, PNI Sensor has worked with EM Microelectronic Marin SA as its supplier of ultra-low-power ICs.

"We foresee a range of applications for SENtrace in wearables. They include wrist-worn devices for locating lost children or elders and enhanced activity wristbands and smartwatches for athletes and fitness enthusiasts," said Becky Oh, president and CEO of PNI Sensor, in a statement.
