Telit expands its line of multi-constellation satellite global positioning receivers with more to follow

Posted by Jeremy CowanMay 23, 2013

CTIA 2013, Las Vegas, NV, USA – Telit Wireless Solutions, a global provider of M2M modules, services and solutions, has introduced the Jupiter SE868-V2 compact multi-constellation receiver module for positioning and navigation. The module is designed for automotive, commercial, industrial, and consumer applications, and includes wearable and handheld devices.

The SE868-V2 receiver module was created to shorten time-to-market, and make the chipset-versus-module decision easy to make for new designs. It is also intended to provide a pin-compatible path for devices based on the Jupiter JF2 GPS module to upgrade to the latest and most robust multi-constellation support available in the market.

The small 11x11mm CSR SiRFstarV™ 5e-based, QFN packaged receiver module supports American Global Positioning System (GPS), Russian Globalnaya navigatsionnaya sputnikovaya sistema (Glonass) and Japanese Quasi-Zenith Satellite System (QZSS).

The company plans to ship market samples of the product’s second version, which is ready to receive satellite signals from European Galileo and Chinese BeiDou Compass (BDS) sat-nav systems, later this year as standards for these constellations are completed.

Telit says that its Jupiter SE868-V2 excels in all positioning tasks and foremost in applications requiring high reliability navigation. Because of its ability to track GPS and Glonass constellations simultaneously it remains in navigation for a much higher percentage of time with no interruptions in the stream of position fixes. It also requires no external management for switching among the different satellite systems. The product features ultra-high sensitivity, up to -165dBm in tracking and -148dBm in acquisition. The SE868-V2 also reduces bill-of-material (BOM) costs of the customer device with an internal low-noise amplifier (LNA) which eliminates the need for costly active antennas.

The SE868-V2 features very low power consumption as well as advanced power-saving modes. It operates on a 1.8V supply at 3.2 mA current when in push-to-fix (PTF) mode and up to 45 mA typical current when engaged in simultaneous GPS and Glonass tracking. For devices upgrading from the JF2 GPS-only receiver, the new receiver is capable of delivering all its enhanced functionality while consuming power levels equivalent to the JF2.  That allows JF2 customers to adopt the SE868-V2 without having to upgrade the device’s power supply which is particularly critical in battery-powered products.

Helping deliver high-value features and robustness, the device’s RF front-end includes advanced jamming detection and an in-DSP removal system allowing it to reject continuous-wave (CW) jamming interference. It can reportedly interface with the host device via standard UART SPI or I2C, hot start in less than one second or cold start in less than 35 seconds. The SE868-V2 also supports the industry’s top assisted GNSS standards allowing the customer solution to reap benefits from faster fixes in obscured or partly obscured sky conditions. Jupiter SE868-V2 is a multi-constellation GNSS product enhanced for maximum sensitivity with minimal sky-visibility – as used indoors, in garages, or urban canyons. Its power saving modes are said to make it battery power friendly and ideal for wearable and personal navigation applications.

“The Jupiter SE868-V2 is one the industry’s first applications of CSR’s latest generation and state-of-the-art, multi-GNSS platform, the CSR SiRFstarV™ 5e. Announcing this product here at CTIA 2013 reaffirms Telit’s leading R&D power in the industry when we can launch a product like the V2 before most competitors sharing similar long-standing presence in the positioning space.” said Dominikus Hierl (pictured above), chief marketing officer at Telit Wireless Solutions. “Now the large customer base for the popular Jupiter JF2 GPS-only module can quickly introduce a new generation of their own products providing them the opportunity to upsell their own customer base.”

Other distinguishing features of the SE868-V2 include reliability enhancing multipath mitigation, cross-correlation mitigation and 8-10dB of 3GPP pass margins. The product roadmap also includes new features like MEMS context detection and navigation aiding Wi-Fi hybrid-positioning; and Cell-ID tracking, data-logging Adaptive Continuous Track (ACT).
