The Jupiter SL871 module uses MediaTek’s low-power MT3333 core, with multi-constellation tracking. It is suited to battery-life sensitive GNSS applications that do not require dead-reckoning, TRAIM and support of communication ports such as USB or CAN bus. The recently introduced companion SL869 V2 module provides these sophisticated features.

The SL871 can track GPS + Galileo and GLONASS (or GPS + Galileo and CompassBeidou depending on the software onboard) constellations, while simultaneously providing positioning data through a standard UART. It features an ultra-sensitive RF front-end that enables multi-GNSS indoor fix, fast fix and navigation in difficult-signal outdoor scenarios such as dense urban areas.

The Jupiter SL871 also supports ephemeris file injection (A-GPS) as well as Satellite Based Augmentation System (SBAS) to increase position accuracy. Its onboard software engine is able to locally predict ephemeris three days in advance starting from ephemeris data broadcast by GNSS satellites received by the module and stored in the internal Flash memory. In addition, advanced power modes and AGPS help in finding the best balance between accuracy and power consumption, significantly increasing battery life.

When designing position-aware, connected devices, developers can benefit from the seamless integration between Telit’s cellular modules and the Jupiter SL871. Bundling these cellular and positioning modules significantly reduces development complexity without adding costs. Multi-GNSS modules applied together with the company’s eCall / ERA-GLONASS compliant cellular modules can, for example, deliver ready-to-use emergency automotive tracking solutions for the European and Russian markets.

Telit adds that the Jupiter SL871 was designed to help developers looking for a quick and painless design-in experience creating geo-location aware products, particularly battery-powered ones… [for example], fleet management systems, GNSS-assisted road tolling, wearable technology, in-car navigation, telematics, and personal monitors.
