LEA-6 - Data Sheet1.4 Block diagramFigure 1 Block diagram (For available options refer to the product features table in section 1.2.)1.5 Assisted GPS (A-GPS)Supply of aiding information like ephemeris, almanac, approximate previous position and time, satellite statusand an optional time synchronization signal will reduce time to first fix significantly and improve the acquisition9sensitivity. All LEA-6 modules support the u-blox AssistNow Online and AssistNow Offline A-GPS services and areOMA SUPL compliant.1.6 AssistNow AutonomousAssistNow Autonomous provides functionality similar to Assisted-GPS without the need for a host or externalnetwork connection. Based on previously broadcast satellite ephemeris data downloaded to and stored by theGPS receiver, AssistNow Autonomous automatically generates accurate satellite orbital data (“AssistNowAutonomous data”) that is usable for future GPS position fixes. AssistNow Autonomous data is reliable for up to3 days after initial capture.u-blox’ AssistNow Autonomous benefits are: Faster position fix No connectivity required Complementary with AssistNow Online and Offline services No integration effort, calculations are done in the backgroundFor more details see the u-blox 6 Receiver Description including Protocol Specification [2].1.7 OscillatorsLEA-6 GPS modules are available in Crystal and TCXO versions. The TCXO allows accelerated weak signalacquisition, enabling faster start and reacquisition times.1.8 GALILEOWhen GALILEO-L1 signals become available, LEA-6H receivers will be capable of receiving and processing themvia a firmware upgrade. The ability to receive and track GALILEO satellite signals will result in higher coverage,improved reliability and better accuracy.9AssistNow Offline requires external memory on the host for LEA-6S, LEA-6A, and LEA-6T-0UBX-14044797Production InformationPage 7 of 26
LEA-6 - Data Sheet1.9 GLONASSThe Russian GLONASS satellite system is an alternative system to the US-based Global Positioning System (GPS).LEA-6H modules are GLONASS ready and are capable of receiving and processing GLONASS signals via afirmware upgrade. For more information about GLONASS and implementation see the u-blox GPS Compendium[4] and the GLONASS & GPS HW Designs Application Note [5].1.10 Protocols and interfacesProtocolTypeNMEAInput/output, ASCII, 0183, 2.3 (compatible to 3.0)UBXInput/output, binary, u-blox proprietaryRTCMInput, 2.3Table 3: Available protocolsAll listed protocols are available on UART, USB and DDC. For specification of the various protocols see theu-blox 6 Receiver Description including Protocol Specification [2].LEA-6 modules support a number of peripheral interfaces for serial communication. The embedded firmwareuses these interfaces according to their respective protocol specifications. For specific applications, the firmwarealso supports the connection of external memories.1.10.1 UARTLEA-6 modules include one configurable UART interface for serial communication (for information aboutconfiguration see section 1.12).1.10.2 USBLEA-6 modules provide a USB version 2.0 FS (Full Speed, 12Mbit/s) interface as an alternative to the UART. Thepull-up resistor on USB DP is integrated to signal a full-speed device to the host.

LEA-6 - Data Sheet1.10.3 SPI (LEA-6R)LEA-6R includes a Serial Peripheral Interface (SPI) for connecting external sensors. The interface can be operatedin SPI master mode only. Two chip select signals are available to select external slaves.LEA-6R default SPI clock is 870 kHz. As LEA-4R default value is 460 kHz, migrating from LEA-4R to LEA-6R willrequire a bandwidth verification of the SPI circuits.1.10.4 Display Data Channel (DDC)2The I C compatible DDC interface can be used either to access external devices with a serial interface or tointerface with a host CPU. It is capable of master and slave operation. DDC is not available with LEA-6R. The22DDC interface is I C Standard Mode compliant. For timing parameters consult the I C standard.The DDC Interface supports serial communication with u-blox wireless modules. See the specification ofthe applicable wireless module to confirm compatibility.The maximum bandwidth is 100kbit/s.1.10.4.1 External serial EEPROMLEA-6A and LEA-6S modules allow an optional external serial EEPROM to be connected to the DDC interface.This can be used to store Configurations permanently.For more information see the LEA-6/NEO-6/MAX-6 Hardware Integration Manual [1].1.11 AntennaLEA-6 modules are designed for use with passive and active antennas.An antenna supervisor is available with all LEA-6 Modules. In the default operation mode the antenna supervisoris activated and enables the receiver to detect short circuits at the active antenna by checking the bias voltagelevel and can shut down the voltage bias immediately. A series resistor is needed in front of the V ANT input.UBX and NMEA messages are provided to report the condition of the antenna supply. Open circuit detection canalso be supported with an additional external circuit.
