    The LEA-6T provides precision GPS timing for demanding
    positioning applications such as femto cells and WiMAX basestations.
    This module features user configurable frequency
    output and timepulse. An accuracy of up to 15 ns is achievable
    by using the quantization error information to compensate the
    granularity of the time pulse. The LEA-6T features a time mode
    function whereby the GPS receiver assumes a stationary 3D
    position, whether programmed manually or determined by an
    initial self-survey.
    During stationary operation GPS timing is possible with only
    one visible satellite. This means that time can be output even
    under adverse signal conditions or in environments with poor
    sky visibility. A built-in time mark and counter unit provide
    precise time measurement of external event inputs. T-RAIM
    (Timing Receiver Autonomous Integrity Monitoring) is available
    to detect faulty GPS measurements. Raw data is also provided.
    LEA-6T modules are based on AEC-Q100 qualified GPS chips
    and are manufactured in ISO/TS 16949 certified sites. Qualification
    tests on LEA-6T modules are performed as stipulated in
    the ISO16750 standard: “Road vehicles – Environmental conditions
    and testing for electrical and electronic equipment”.
