Precision Timing GPS Module only requires one satellite.April 7, 2008 -
Capable of (compensated) time pulse accuracy of up to 15 ns, LEA-5T offers Time Mode function whereby GPS receiver assumes stationary position that can be programmed manually or determined by initial self-survey. Stationary operation enables GPS timing with only one visible satellite and eliminates timing errors. Along with SuperSense KickStart weak signal acquisition technologies, module incorporates time mark and counter unit for globally synchronized time stamping/measuring.

u-blox Unveils LEA-5T Precision Timing GPS Module at CTIA
THALWIL, Switzerland, April 2 -- u-blox, the leading Swiss provider of GPS receiver technology, today introduced the LEA-5T, a high performance, precision timing GPS module capable of a (compensated) time pulse accuracy of up to 15 ns.
With more than 1.100 exhibiting companies and over 40.000 visitors, CTIA WIRELESS 2008 offers professionals in broadband convergence, enterprise, advertising, social networking and entertainment a unique chance to meet, exchange views and do business.
u-blox will be promoting its latest technology innovations, including the LEA-5T precision timing GPS module. Needing just one satellite to operate, the LEA-5T is a cost-efficient, compact and easy-to-integrate solution ideally suited for telecom network synchronization such as UMTS, CDMA or the Chinese TD-CDMA, as well as for applications that need time-accurate data communication between geographically dispersed systems and devices such as NTP servers.
"The revolutionary LEA-5T GPS module brings precision timing at low cost," said Thomas Seiler, u-blox CEO. "The module's compact architecture and affordability enables consumer device applications to benefit from highly accurate timing, enabling applications such as WiMAX base stations for home-based broadband networks," added Mr. Seiler.
The LEA-5T features a Time Mode function whereby the GPS receiver assumes a stationary position, which can be programmed manually or be determined by an initial self-survey. Stationary operation enables GPS timing with only one visible satellite and eliminates timing errors which otherwise result in positioning errors.
A built-in time mark and counter unit provides a globally synchronized time stamping and time-measuring functionality useful in applications such as seismic sensors or other applications with wide-area synchronization needs.
The module is powered by the 50-channel, u-blox 5 positioning engine. Endowed with SuperSense KickStart weak signal acquisition technologies, u-blox 5 GPS chips and modules boast an acquisition and tracking sensitivity of -160 dBm that enables fast, uninterrupted operation, even in challenging, weak signal environments like indoor locations.
Samples can be ordered from http://u-blox.com/shop/ from next week onwards; mass production begins end of April. Please contact u-blox sales sales@u-blox.com or visit u-blox' booth at CTIA, April 1-3, Las Vegas, NV, USA, at Hall C3, Booth 3827 for details.
