The LEA‑6R provides 100 % coverage, combining the high performance u‑blox 6 positioning engine with u‑blox’ ADR Dead Reckoning technology. ADR supplements GPS satellite position information with heading and distance data provided by additional sensors. When GPS satellites are out of sight, location is extrapolated using distance and angle information from the gyroscope and speedpulse sensors. The speedpulse sensor signal can be received either as a digital tick signal or as messages via the serial interface. The gyroscope is monitored via an external ADC over the SPI interface. ADR enables accurate navigation even in locations with poor or absent GPS signals such as tunnels, indoor parking facilities and deep urban canyons. In addition, ADR effectively eliminates the impact of multipath effects in urban canyon environments. This makes the LEA‑6R the ideal solution for applications requiring accurate, reliable positioning, all of the time. LEA‑6R modules are manufactured in ISO/TS 16949 certified sites. Each module is tested and inspected during production. Qualification tests are performed as stipulated in the ISO16750 standard: “Road vehicles – Environmental conditions and testing for electrical and electronic equipment”.
