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”. • Microsoft® certified USB driver Receiver type 50-channel u-blox 6 engine GPS L1 C/A code SBAS: WAAS, EGNOS, MSAS, GAGAN Navigation update rate up to 5 Hz Accuracy1 Position 2.5 m CEP SBAS 2.0 m CEP Acquisition1 Cold starts: 29 s Aided starts2: < 1 s Hot starts: < 1 s Sensitivity3 Tracking: –160 dBm Reacquisition: –160 dBm Cold starts: –147 dBm Hot starts: –156 dBm
