This module features user configurable frequency and timepulse out- puts. An accuracy of up to 15 ns is achievable by using the quanti- zation error information to compensate the granularity of the time pulse. NEO-6T/LEA-6T feature a time mode function whereby the GPS receiver assumes a stationary 3D position, whether pro- grammed 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 maintained 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. NEO-6T/LEA-6T deliver raw pseudo- range data for survey and specialist applications. NEO-6T/LEA-6T modules are manufactured in ISO/TS 16949 certi- fied sites. Each module is tested and inspected during production. Qualification tests are performed as stipulated in the ISO16750 standard: “Road vehicles – Environmental conditions and test- ing for electrical and electronic equipment”.
