Telit‘s Jupiter SE873Q5 module is now available. The SE873Q5 is an ultra-low-power, high-sensitivity GNSS module with very small physical dimensions, completely compatible with its SE873 module.

The new module leverages Telit innovation in miniaturization technology to improve power saving and sensitivity, delivering longer battery life and expanding design possibilities for tracking and navigation application areas particularly in wearable devices.

The multi-constellation receiver module can be set to a number of different power saving modes depending on application requirements and includes an ultra-low noise boosting sensitivity that allows developers to explore a wider variety of device designs, enclosures and relative placement inside personal devices, garments or other space constrained electronics.

The SE873Q5 is a flash-memory-based GNSS module capable of tracking three constellations simultaneously. Compared to the SE873, the new design reduces power consumption by 20%, while boosting satellite signal reception sensitivity. With complete pin-to-pin compatibility, the SE873Q5 can also be applied to existing designs based on the SE873, instantly boosting device performance as well as creating opportunities for new and upgraded products with very short time-to-market.

“When it comes to application areas like wearables and others in the commercial and consumer spaces, there is no such thing as ‘too small’ or ‘too power-efficient’,” said Felix Marchal, Telit’s executive vice president of GNSS and short-range wireless. “And when you add to this type of efficiency, a stellar front-end RF performance in a miniature global satellite positioning receiver module, you immediately open up new product and business opportunities because now your antenna requirements are easier to meet; and you can explore more ‘buried’ designs where the module, used with an integrated antenna, can be encased deeper into the physical environment of the consumer, commercial or industrial application.”

Features

  • The Jupiter SE873Q5 is packaged in a 7x7x1.85 mm QFN-like package, equipped SQI Flash memory, switching power supply and integrated high-performance low-noise amplifier (LNA). It is designed to support GPS, GLONASS, BeiDou and is Galileo-ready, delivering simultaneous tracking in two modes: GPS+Galileo and GLONASS, or GPS+Galileo and BeiDou.
  • To extend battery life, the module includes a low-power tracking mode as well as advanced low-power modes: SmartGNSS 1 and 2, duty cycle, push-to-fix. Because it is flash-memory-based, it enables easy firmware updates, customization of operating parameters and supports ephemeris file injection (A-GPS) for up to 14 days, resulting in faster TTFF.
  • Navigation data is delivered using OSP binary protocol or NMEA through standard UART, SPI or I2C ports. The module supports A-GPS as well as Satellite Based Augmentation System (SBAS) to increase position accuracy. Server-generated and client-generated extended ephemeris are supported and stored in internal Flash memory. The enhanced sensitivity of the SE873Q5 is rated at -147dBm for acquisition, -161dBm for navigation and -167dBm for tracking.
