Fujitsu Electronics will be presenting at this week’s Electronica show in Munich a multi-receiver GNSS module for applications such as smart watches, fitness trackers, logistics (asset tracking and monitoring), and indoor or outdoor navigation.
The MSB1054 is for GNSS applications that encompass not only GPS but also Glonass, QZSS, SBAS, Galileo and Beidou. The ability to receive signals from several satellite systems significantly reduces the TTFF (time to first fix), meaning faster and more accurate positioning.
Beside the GNSS device itself, the module includes a built-in RF-front end with SAW filter, LNA and TCXO, so with the exception of an antenna no external component is required. Furthermore, the Japanese company’s GNSS module is equipped with a built-in flash memory for quick hot start to save the navigation data and optimise its performance.
Dimensions are 5.8 by 6.2 by 1mm, and it draws 3.4mA current in low-power mode.
Various synergies arise between this module and Fujitsu's existing portfolio, as it already offers a range of components and services that support the development of low-power and IoT products. Examples include FRAM as well as Ambiq Micro's MCUs, RTCs, Bluetooth LE and energy harvesting devices.
Fujitsu is working with US company InnoPhase in exploring its low-power PolarFusion radio architecture for battery-based wireless IoT applications. The radio architecture moves RF processing functionality from power-hungry and large analogue circuits into efficient, low-power digital logic.
This opens possibilities in the use of wifi, Bluetooth, Zigbee and other popular protocol radios. The lower power consumption could enable a whole class of battery-based IoT devices.
Immediately after the market launch of InnoPhase's first product at the beginning of 2018, the Talaria One ULP wifi radio, Fujitsu has been evaluating the potential of wifi being available in battery-based applications. Based on customer feedback and ideas, InnoPhase is now planning to expand the device’s feature set in a product coming early next year.
“Within our focus on ultra-low power and IoT applications, Fujitsu engineering is currently testing InnoPhase’s wifi-based technologies in combination with the products of our other ultra-low power vendors,” said Klaus-Peter Dyck, Fujitsu’s marketing manager. “We are working directly with InnoPhase to create a foundation to fully support this new technology in future Fujitsu projects in Europe.”
