u-blox 5 modules are not recommend for
new designs. Please use the latest u-blox 6 based GPS receiver modules for new
designs.
The LEA-5T Precision Timing GPS module is ideally suited for
applications that require highly accurate timing, high sensitivity,
low power consumption and USB connectivity.
The LEA-5T 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. The accuracy of the time pulse is as good as 30 ns,
synchronized to GPS or UTC time. An accuracy of 15 ns is achievable
by using the quantization error information to compensate the
granularity of the time pulse. A built-in time mark and counter
unit provides precise time measurement of an external signal
("EXTINT0" input).
Powered by the 50-channel u-blox 5 positioning engine, the
module boasts a Time-To-First-Fix of under 1 second. The dedicated
acquisition engine, with over 1 million correlators, is capable of
massive parallel time/frequency space searches, enabling it to find
satellites instantly. Innovative design and technology suppresses
jamming sources and mitigates multipath effects, giving u-blox 5
GPS receivers excellent navigation performance even in the most
challenging environments.
