Memsic thermal accelerometer backs up GPS

Memsic product story

Memsic's thermal accelerometer will be used in Tom Tom's car navigation device, guiding when GPS signals are broken.
Memsic, a provider of CMOS-based MEMS accelerometers/sensors, has been selected to supply its thermal accelerometer to Tom Tom for use in the company's all in one car navigation device, the TomTom Go.
The accelerometer will be used for determining travel distance using "dead reckoning" navigation and is activated when the GPS signal is lost.
GPS signal loss can occur for example, when travelling through a tunnel or in underground parking structures.
"Our highly reliable thermal accelerometer product does not require special manufacturing systems, and currently has a failure rate of 1.75ppm" said Memsic CEO, Dr Yang Zhao.
"Once again Memsic has demonstrated through higher reliability, that our accelerometers provide the lowest total cost of ownership in the industry".
Through established manufacturing partnerships in Asia with TSMC and Fujitsu, Memsic has reduced operational costs by outsourcing nearly 90% of its manufacturing, resulting in products that offer the highest reliability, meet the most stringent quality standards and offer customers a significantly lower cost of ownership compared tocompeting technologies.
Memsic also recently opened its new 4000m2 facility in Wuxi, Jiangsu Province, China.
About a two-hour drive from Shanghai, this new facility has a manufacturing capacity of three million units per month.
As the only dual-axis accelerometer fabricated on a monolithic CMOS process, Memsic's cost-effective products are advancing into many new consumer applications and are being used for virtually any application that requires the sensing of motion, acceleration, vibration or tilt.
