The u-blox LEA-6T supports precision GPS timing for demanding
positioning applications such as femto cells and WiMAX
basestations. It features a time mode function whereby the GPS
receiver assumes a stationary 3D position, whether programmed
manually or 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. An accuracy of up to 15ns is achievable by
using the quantization error information to compensate the
granularity of the time pulse.
LEA-6T has a built-in time mark and counter unit provide precise
time measurement of external event inputs. The best way to discover
the feature rich benefits of LEA-6T is to purcahse an easy-to-use
EVK-6T Precision Timing Evaluation Kit which is supplied with free
software and user guide.
Comprehensive development support is available from our team of
experts.

U-blox 6 is the next generation of GPS chips and module
solutions from from u-blox. It features extremely low power
performance for GPS applications and increased sensitivity while
maintaining the fastest acquisition time available in todays
market.
Features of the AMY, MAX, NEO and LEA GPS u-blox-6 module
families include position, velocity, time and Dead Reckoning used
in a wide range of navigation, tracking, precision timing and
location-based applications. The product selection table
below represents the range of GPS modules available and for, larger
volume users, chip solutions are also available.
Purchasing the u-blox 6 precision timing evaluation kit, EVK-6T,
is by far the best way to learn about the high performance LEA-6T
u-blox 6 GPS module for precision timing applications.
The EVK-6T is compact, and its user-friendly USB interface and
power supply options make it ideally suited for use in
laboratories, vehicles and outdoor locations. Furthermore, the
EVK-6T can be used with a PDA or a notebook PC, making it the
perfect companion through all stages of design-in projects.
