Atmel and u-blox cooperate on low GPS signal tracking technology

LONDON — Atmel (Heilbronn, Germany) and u-blox (Thalwil, Switzerland) have developed the SuperSense GPS weak signal tracking technology, which supports Atmel's ANTARIS GPS chipsets and GPS modules from u-blox. The software will enable accurate GPS navigation in building interiors, deep urban canyons, covered roads and other locations where GPS reception has previously been impossible.

SuperSense targets mass-market, automotive and handheld, FCC E-911 Phase II-compliant GPS product applications. An ANTARIS SuperSense-based products' sensitivity enables antennas to be moved to a vehicle's interior, allowing products with integrated antennas mounted in glove compartments and under seats, thus reducing automotive GPS installation costs when compared with systems requiring a separate, external antenna. The ANTARIS GPS engine has been jointly developed by Atmel and u-blox and the 16-channel ANTARIS features 8,192 simultaneously operating time/frequency search windows. This improves acquisition sensitivity for stand-alone and A-GPS operation, enabling satellite search and position calculation in previously GPS-dead areas.

SuperSense combines tracking sensitivity beyond -158 dBm, lower power consumption and good navigation performance. It is available as beta release when purchasing the SuperSense Evalkit or the TIM-LH GPS module. It will support the complete ANTARIS GPS portfolio from Atmel as well as TIM-LH modules from u-blox.
