GPS module has impeccable timing
The LEA-5T is a cost-efficient, compact and easy-to-integrate solution ideally suited for telecomms network synchronisation.
New from u-blox, the LEA-5T is a high-performance precision timing GPS module capable of a (compensated) time pulse accuracy up to 15ns Needing just one satellite to operate, the LEA-5T is a cost-efficient, compact and easy-to-integrate solution ideally suited for telecomms network synchronisation 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

Tracking technology makes sense of weak GPS
Atmel and u-blox have codeveloped a new GPS weak-signal tracking technology, called SuperSense, supporting Atmel's Antaris GPS chipsets and GPS modules from u-blox.
Firmware upgrades GPS chipset performance
GPS module maker u-blox has released the final SuperSense firmware for its TIM-LH GPS receiver modules and Antaris GPS chipsets.
"The revolutionary LEA-5T GPS module brings precision timing at low cost", says 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 basestations for home-based broadband networks".
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 synchronised time stamping and time-measuring functionality useful in applications such as seismic sensors or other applications with wide-area synchronisation 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 -160dBm that enables fast, uninterrupted operation, even in challenging, weak signal environments like indoor locations.
