Indoor-capable GPS signal tracking technology for mobile products
13 July 2005, Telecoms, Datacoms, Wireless, IoT
Atmel and u-blox have announced a new GPS weak signal tracking technology they call SuperSense. It supports Atmel's Antaris GPS chipsets and GPS modules from u-blox. With this new GPS software, accurate GPS navigation becomes possible in building interiors, deep urban canyons, covered roads and other locations where GPS reception has previously been impossible, claim the companies. Previously, such areas prevented effective GPS navigation due to systems' inability to effectively receive faint GPS tracking signals.
SuperSense targets mass-market, automotive and handheld, FCC E-911 Phase II-compliant GPS product applications. Of particular benefit is the high sensitive dynamic navigation performance of existing and future Antaris-based chipsets from Atmel and modules from u-blox. Because of Antaris SuperSense-based products' sensitivity, antennas can be moved to a vehicle's interior, allowing products with integrated antennas mounted in glove compartments and under seats, so reducing automotive GPS installation costs when compared with systems requiring a separate, external antenna.
The 16-channel Antaris GPS engine, jointly developed by Atmel and u-blox, features 8192 simultaneously operating time/frequency search windows. This substantially improves acquisition sensitivity for standalone and A-GPS operation, enabling satellite search and position calculation in previously GPS-dead areas. SuperSense combines superior tracking sensitivity beyond -158 dBm, low power consumption and high navigation performance.
It is available as beta release when purchasing the SuperSense Evalkit or the TIM-LH GPS module, and supports the complete Antaris GPS portfolio as well as TIM-LH modules. |
