GNSS module tracks multiple constellations at once
Telit Wireless Solutions has released a multi-constellation GNSS module based on MediaTek's low-power MT3333 core for battery-life sensitive applications that do not require Dead Reckoning, TRAIM and USB or CAN bus support.
The Jupiter SL871 can simultaneously track GPS+ Galileo and GLONASS (or GPS + Galileo and CompassBeidou depending on the SW onboard) constellations, providing the positioning data through standard UART. Its 165dBm RF front-end enables multi-GNSS indoor fix, fast fix and navigation in challenging outdoor scenarios such as dense urban areas.
The GNSS module comes with an SL869 companion, and supports ephemeris file injection as well as Satellite Based Augmentation System 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, which is 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 to increase the battery life.
When designing position-aware, connected devices, developers can benefit significantly 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.
"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," said Taneli Tuurnala, VP and Head of GNSS Division at Telit Wireless Solutions.
