All LEA-6 modules support the u-blox AssistNow Online and AssistNow Offline A-GPS services andare OMA SUPL compliant.1.6 SuperSense Indoor GPSAll LEA-6 modules come with SuperSense, providing improved acquisition/reacquisition and tracking sensitivity.SuperSense enables high performance tracking and navigation even in difficult signal environments such asurban canyons or indoor locations.1.7 KickStart / OscillatorsAn available feature is KickStart. This functionality uses a TCXO to accelerate weak signal acquisition, enablingfaster start and reacquisition times. KickStart is available with the LEA-6H, LEA-6S and LEA-6T.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.10Requires external memory on the Host for ROM based ModulesGPS.G6-HW-09004-DPreliminaryPage 7 of 29

For specification of the various protocols see the u-blox 6Receiver 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.1.9.1 UARTLEA-6 modules include one configurable UART interface for serial communication (for information aboutconfiguration see section 1.12).1.9.2 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. The VDDUSB pin supplies theUSB interface. u-blox provides a Microsoft certified USB driver for Windows XP, Windows Vista and Windows 7 operatingsystems.Operating SystemSupport levelWindows XPWindows VistaCertifiedCertifiedWindows 7CertifiedTable 4: Operating systems supported by USB driver1.9.3 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.1.9.4 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 is compatible with LEON DDC from version LEON-G100-05S/ LEON-G200-05S and aboveThe maximum bandwidth is 100kbit/s.1.9.4.1 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.11Only on LEA-6H-0 with FW7.01GPS.G6-HW-09004-DPreliminaryPage 8 of 29

LEA-6 - Data Sheet1.10 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. For details, please refer to the LEA-6/NEO-6 HardwareIntegration Manual [1].ParameterSpecificationAntenna TypeActive Antenna RecommendationsPassive and active antenna15 dB (to compensate signal loss in RF cable)50 dB1.5 dBMinimum gainMaximum gainMaximum noise figureTable 5: Antenna specifications1.11 Power Managementu-blox receivers support different power modes. These modes represent strategies of how to control theacquisition and tracking engines in order to achieve either the best possible performance or good performancewith reduced power consumption.For more information about power management strategies, see the u-blox 6 Receiver Descriptionincluding Protocol Specification [2].1.11.1 Maximum Performance ModeDuring a Cold start, a receiver in Maximum Performance Mode continuously deploys the acquisition engine tosearch for all satellites. Once the receiver has a position fix (or if pre-positioning information is available), theacquisition engine continues to be used to search for all visible satellites that are not being tracked.1.11.2 Eco ModeDuring a Cold start, a receiver in Eco Mode works exactly as in Maximum Performance Mode. Once a positioncan be calculated and a sufficient number of satellites are being tracked, the acquisition engine is powered offresulting in significant power savings. The tracking engine continuously tracks acquired satellites and acquiresother available or emerging satellites.Note that even if the acquisition engine is powered off, satellites continue to be acquired.1.11.3 Power Save ModePower Save Mode (PSM) allows a reduction in system power consumption by selectively switching parts of thereceiver on and off.Power Save mode is not available with LEA-6R.1.12 Configuration1.12.1 Boot-time configuration (LEA-6A, LEA-6S)LEA-6
