Telit’s Jupiter SE880 48-channel Receiver Accelerates Cold Start Time-to-First-Fix by more than 200 Seconds with Class Leading – 148dBm Sensitivity – Industry’s Most Sensitive
London, October 8, 2012 – Telit Wireless Solutions, a leading global vendor of high-quality machine-to-machine (M2M) modules and value-added services, today announced the introduction of the Jupiter SE880 ultra-compact GPS receiver module for applications in the commercial, industrial, and consumer segments including wearable and handheld devices. The miniature 4.7×4.7mm LGA (Land Grid Array), SiRFstarIVTM-based receiver module employs leading 3-D component embedding technology to achieve best-in-class performance in all dimensions critical for regular or size-constrained GPS applications. The SE880 receiver module was conceived to shorten Time-to-Market and to make the chipset-versus-module decision an easy one to make for device integrators. Integrators can attain a working SE880-based design in as little as a week versus several months when starting from a chipset reference design.
Telit’s Jupiter SE880 includes all components necessary for a fully functioning receiver design requiring only a 32 KHz external crystal for its time-base and TCXO to complete the design, along with antenna, power and data connections adequate to the integrator’s needs. For advanced designs incorporating the supported Satellite Based Augmentation System (SBAS), ephemeris data collected from the satellites can be stored to SPI Flash memory instead of the more common and expensive alternative of the EEPROM – again reducing costs and improving the business case for the end-device.
Responsible for delivering the device’s best-in-class sensitivity, the Jupiter SE880’s RF front-end is truly state of the art employing spatially calibrated waveguide-quality radio paths inside the three-dimensional space of its architecture drastically reducing parasitic impedances characteristic of traditional 2-D RF designs. Inside, a multi-filter system includes not only the traditional SAW filters typical in GPS receiver designs but also a 2.4 GHz notch-filter capable of nullifying the jamming effects of high-energy radio devices such as Wi-Fi hot-spots, Bluetooth systems, cordless phones, and others, which greatly affect a GPS receiver’s ability to resolve timid satellite signals in the hostile radio environment where they need to operate.
Jupiter SE880 is a single-constellation GPS product enhanced for maximum sensitivity which makes it capable of class-unique achievements such as a one-satellite acquisition of UTC (typically 4 are required); fix acquisition with minimal sky-visibility – indoors, garages, urban canyons, etc.; and much lower TTFF under standard operating conditions (as much as 200 seconds quicker from cold start). In its micro-power stand-by mode, the SE880 draws a low 50 to 500 µAmps making it extremely battery-power friendly. Waking from this mode it can produce a first-fix in a few seconds when waking from a few hours of stand-by and still less than 10 seconds when waking from a full day of stand-by, making it ideal for wearable and personal digital device applications.
