u-blox sets new benchmark for GNSS precision timing with two new modules

NEO‑M8T and LEA‑M8T provide smooth multi‑GNSS upgrade path for high precision and portable timing applications
u‑blox NEO‑M8T and LEA‑M8T set new industry benchmark for satellite‑based precision timing
u‑blox NEO‑M8T and LEA‑M8T set new industry benchmark for satellite‑based precision timing

Thalwil, Switzerland – Nov. 26, 2014 - Swiss‑based u‑blox, a global leader in cellular and positioning modules and integrated circuits, announces the NEO‑M8T and LEA‑M8T precision timing modules. The compact, surface‑mount modules are able to generate a precise reference clock with <20 ns accuracy. The receivers offer high sensitivity (-157 dBm signal acquisition with assisted GNSS) that enables quick start‑up even inside structures with limited sky‑view. The precise reference clock is derived from multi‑GNSS (Global Navigation Satellite Systems) including GPS, GLONASS, and BeiDou.

 

The LEA‑M8T module is footprint compatible with existing LEA‑5T/6T designs, facilitating easy upgrade. The NEO‑M8T is optimized for timing applications requiring low power consumption and long battery life such as geophones used for seismic field measurements. The modules meet stringent requirements for reliability, accuracy and low power consumption.

 

“These new modules are the industry’s highest performance GNSS timing modules in terms of accuracy, reliability and power consumption,” said Thomas Nigg, Vice President of Product Marketing at u‑blox, “The new modules are perfect solutions for mission‑critical infrastructure systems including mobile communication networks, power generation and distribution systems and seismic measurements.”

 

The NEO and LEA‑M8T modules are multi‑GNSS, pin compatible successors to u‑blox’ existing PPS timing modules and complements the previously announced GNSS disciplined frequency reference module, LEA‑M8F.  

Measuring only 12.2 x 16.0 mm (NEO‑M8T) and 17.0 x 22.4 mm (LEA‑M8T), the modules deliver high integrity and reliability with RAIM (Receiver Autonomous Integrity Monitoring) and alarms, which are crucial features for extremely reliable operation. Two time‑pulse outputs are available, configurable from once per minute up to 10 MHz. The modules also output multi‑GNSS RAW data including carrier phase, code phase and pseudo‑ranges.

The modules can deliver time according to any international standard including calibration of inter‑constellation offsets. Survey‑in and single satellite timing features increase timing accuracy and timing availability with as few as one single satellite in view. Support for low duty cycle operation reduces power consumption for battery‑powered applications which results in cost savings as smaller batteries can be used.

 

The M8T timing modules are delivered in u‑blox’ established LEA and NEO form‑factors with standardized pin‑out, allowing ready migration from previous product generations. u‑blox timing products can make optional use of u‑blox AssistNow or industry standard aiding data. This reduces the time to first fix and delivers exceptional acquisition sensitivity, even on first installation before precise location or time is known.

 

For samples and evaluation kit EVK‑M8T, please contact the u‑blox sales representative nearest you.

 

The modules will be demonstrated at the Small Cells Americas exhibition in Dallas, Texas, Dec. 1‑3, 2014 at u‑blox stand number 28. To set up a meeting, please send an email to info_us@u-blox.com
