All LEA-6 modules support the u-blox AssistNow Online and AssistNow Offline A-GPS services and are OMA SUPL compliant. 1.6 AssistNow Autonomous AssistNow Autonomous provides functionality similar to Assisted-GPS without the need for a host or external network connection. Based on previously broadcast satellite ephemeris data downloaded to and stored by the GPS receiver, AssistNow Autonomous automatically generates accurate satellite orbital data ("AssistNow Autonomous data") that is usable for future GPS position fixes. AssistNow Autonomous data is reliable for up to 3 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 background For more details see the u-blox 6 Receiver Description including Protocol Specification [2]. 1.7 Oscillators LEA-6 GPS modules are available in Crystal and TCXO versions. The TCXO allows accelerated weak signal acquisition, enabling faster start and reacquisition times. 1.8 GALILEO When GALILEO-L1 signals become available, LEA-6H receivers will be capable of receiving and processing them via a firmware upgrade. The ability to receive and track GALILEO satellite signals will result in higher coverage, improved reliability and better accuracy. 9 AssistNow Offline requires external memory on the host for LEA-6S, LEA-6A, and LEA-6T-0 UBX-14044797 Production Information Page 7 of 26 LEA-6 - Data Sheet 1.9 GLONASS The 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 a firmware 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 interfaces Protocol Type NMEA Input/output, ASCII, 0183, 2.3 (compatible to 3.0) UBX Input/output, binary, u-blox proprietary RTCM Input, 2.3 Table 3: Available protocols All listed protocols are available on UART, USB and DDC. For specification of the various protocols see the u-blox 6 Receiver Description including Protocol Specification [2]. LEA-6 modules support a number of peripheral interfaces for serial communication. The embedded firmware uses these interfaces according to their respective protocol specifications. For specific applications, the firmware also supports the connection of external memories. 1.10.1 UART LEA-6 modules include one configurable UART interface for serial communication (for information about configuration see section 1.12). 1.10.2 USB LEA-6 modules provide a USB version 2.0 FS (Full Speed, 12Mbit/s) interface as an alternative to the UART. The pull-up resistor on USB_DP is integrated to signal a full-speed device to the host. The VDDUSB pin supplies the USB interface. (R) u-blox provides a Microsoft certified USB driver for Windows XP, Windows Vista and Windows 7 operating systems. Operating System Support level Windows XP Certified Windows Vista Windows 7 Certified Certified Table 4: Operating systems supported by USB driver UBX-14044797 Production Information Page 8 of 26 LEA-6 - Data Sheet 1.10.3 SPI (LEA-6R) LEA-6R includes a Serial Peripheral Interface (SPI) for connecting external sensors. The interface can be operated in 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 will require a bandwidth verification of the SPI circuits. 1.10.4 Display Data Channel (DDC) 2 The I C compatible DDC interface can be used either to access external devices with a serial interface or to interface with a host CPU. It is capable of master and slave operation. DDC is not available with LEA-6R. The 2 2 DDC 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 of the applicable wireless module to confirm compatibility. The maximum bandwidth is 100kbit/s. 1.10.4.1 External serial EEPROM LEA-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 Antenna LEA-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 supervisor is activated and enables the receiver to detect short circuits at the active antenna by checking the bias voltage level 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 can also be supported with an additional external circuit. For details, please refer to the LEA-6/NEO-6/MAX-6 Hardware Integration Manual [1]. Parameter Specification Antenna Type Active Antenna Recommendations Minimum gain Maximum gain Maximum noise figure Passive and active antenna 15 dB (to compensate signal loss in RF cable) 50 dB 1.5 dB Table 5: Antenna specifications 1.11.1 Power Management u-blox receivers support different power modes. These modes represent strategies of how to control the acquisition and tracking engines in order to achieve either the best possible performance or good performance with reduced power consumption. For more information about power management strategies, see the u-blox 6 Receiver Description including Protocol Specification [2]. 1.11.2 Maximum Performance Mode During a Cold start, a receiver in Maximum Performance Mode continuously deploys the acquisition engine to search for all satellites. Once the receiver has a position fix (or if pre-positioning information is available), the acquisition engine continues to be used to search for all visible satellites that are not being tracked. UBX-14044797 Production Information Page 9 of 26 LEA-6 - Data Sheet 1.11.3 Eco Mode During a Cold start, a receiver in Eco Mode works exactly as in Maximum Performance Mode. Once a position can be calculated and a sufficient number of satellites are being tracked, the acquisition engine is powered off resulting in significant power savings. The tracking engine continuously tracks acquired satellites and acquires other available or emerging satellites. Note that even if the acquisition engine is powered off, satellites continue to be acquired. 1.11.4 Power Save Mode Power Save Mode (PSM) allows a reduction in system power consumption by selectively switching parts of the receiver on and off. Power Save mode is not available with LEA-6R. 1.12 Configuration 1.12.1 Boot-time configuration (LEA-6A, LEA-6S) LEA-6A and LEA-6S modules provide CFG_COM1 for boot-time configuration. This pin becomes effective immediately after start-up. Once the module has started, the configuration settings can be modified with UBX configuration messages. The modified settings remain effective until power-down or reset. If these settings have been stored in battery-backup RAM, then the modified configuration will be retained, as long as the backup battery supply is not interrupted. UART settings can be can be configured as seen in Table 6 with the CFG_COM1 pin. Default settings in bold. CFG_COM1 Protocol Messages UARTBaud rate 1 0 NMEA NMEA GSV, RMC, GSA, GGA, GLL, VTG, TXT GSV 10, RMC, GSA, GGA, VTG, TXT 9600 4800 Table 6: Supported CFG_COM1 settings (LEA-6A, LEA-6S) 1.12.2 Configuration (LEA-6H, LEA-6R, LEA-6T) With the LEA-6H, LEA-6R and LEA-6T, configuration settings modified with UBX configuration messages can be saved permanently. In this case the modified settings remain effective even after power-down and don't require backup battery supply. LEA-6T-0 includes a serial Flash memory for storage of configuration. Saving full configurations might take several seconds to store on LEA-6T-0. Do not power down the Module before receiving the acknowledge. For more information, see the u-blox 6 Receiver Description including Protocol Specification [2]. 1.13 Design-in In order to obtain the necessary information to conduct a proper design-in, u-blox strongly recommends consulting the LEA-6/NEO-6/MAX-6 Hardware Integration Manual [1]. 10 Every 5th fix. UBX-14044797 Production Information Page 10 of 26 LEA-6 - Data Sheet 1.14 Dead Reckoning (LEA-6R) LEA-6R receivers supplement the GPS information with an incoming signal from a gyroscope (turn rate sensor) and odometer pulses to do dead reckoning navigation through periods of poor GPS reception. Depending on the quality of the available GPS signals, the LEA-6R uses an algorithm specially developed by u-blox in order to compute the next positions accurately by using an automatically weighted average of the GPS and sensor inputs. This provides precise navigation in locations with no or impaired GPS reception, for example in tunnels, indoor car parks and deep urban canyons. The LEA-6R is a low power dead reckoning GPS receiver module. The LEA-6R is the ideal solution for applications requiring accurate, reliable positioning, all of the time. The LEA-6R includes a front-end LNA. 1.14.1 Supported peripheral components (LEA-6R) The LEA-6R supports the following peripheral components: A/D converters with SPI interface Linear Technology, LTC1860, 12-bit A/D converter digital temperature sensors with SPI interface National Semiconductors, LM70, precision: 10 bits plus sign Table 7: Supported peripheral components Gyroscopes should at least meet the requirements listed below: Parameter Supply Voltage Specification 5.0 V 0.25 V Zero Point 2.5 V 0.4 V Sensitivity 25 mV//s 5 mV//s Dynamic Range Linearity 60/s to 125/s 0.5% (Full scale) Recommended operating temperature range -40C to +85C Table 8: Required Specifications for Gyroscopes Gyroscopes with a sensitivity of lower than 20 mV//s may work but the performance will be degraded. For this reason u-blox does not recommend using gyroscopes with a lower sensitivity. For implementation details as well as a list of supported gyroscopes that u-blox is currently aware of, or for more information about Dead Reckoning and other special features of the LEA-6R refer to the LEA-6/NEO-6/MAX-6 Hardware Integration Manual [1] and the u-blox 6 Receiver Description including Protocol Specification [2]. UBX-14044797 Production Information Page 11 of 26 LEA-6 - Data Sheet 1.15 Precision Timing & Raw Data (LEA-6T) Timing and Raw data features are available in three Module versions, the LEA-6T-0, LEA-6T-1 and LEA-6T-2. All are pin-compatible Modules. The LEA-6T-1 and LEA-6T-2 include internal Flash memories for firmware updates. 1.15.1 Time mode LEA-6T provides a special Time Mode to provide higher timing accuracy. The LEA-6T is designed for use with stationary antenna setups. The Time Mode features three different settings described in Table 9: Disabled, Survey-In and Fixed Mode. For optimal performance entering the position of the antenna (when known) is recommended as potential source of errors will be reduced. Time Mode Settings Description Disabled Standard PVT operation Survey-In The GPS receiver computes the average position over an extended time period until a predefined maximum standard deviation has been reached. Afterwards the receiver will be automatically set to Fixed Mode and the timing features will be activated. Fixed Mode In this mode, a fixed 3D position and known standard deviation is assumed and the timing features are activated. Fixed Mode can either be activated directly by feeding pre-defined position coordinates (ECEF - Earth Center Earth Fixed format) or by performing a Survey-In. In Fixed mode, the timing errors in the TIMEPULSE signal which otherwise result from positioning errors are eliminated. Single-satellite operation is supported. For details, please refer to the u-blox 6 Receiver Description including Protocol Specification [2]. Table 9: Time mode settings 1.15.2 Timepulse and frequency reference LEA-6T-0 and LEA-6T-1 not only feature the new u-blox 6 engine with its extra acquisition sensitivity, they also comes with a 2nd timepulse output, which can be configured from 0.25 Hz up to 10 MHz. One timepulse can be used for time synchronization (i.e. 1 pulse per second), while the 2nd timepulse can be used with LEA-6T as a reference frequency in the MHz range. A timepulse in the MHz range provides excellent long-term frequency accuracy and stability. This brings cost savings for LEA-6T customers since it is no longer necessary to generate an additional reference frequency with their circuitry. (LEA-6T-2 supports only a single timepulse output.) 1.15.3 Time mark LEA-6T can be used for precise time measurements with sub-microsecond resolution using the external interrupt (EXTINT0). Rising and falling edges of these signals are time-stamped to the GPS or UTC time and counted. The Time Mark functionality can be enabled with the UBX-CFG-TM2 message For details, please refer to the u-blox 6 Receiver Description including Protocol Specification [2]. 1.15.4 Raw data Raw data output is supported at an update rate of 5 Hz on the LEA-6T-0 and 2 Hz on the LEA-6T-1 and LEA-6T2. The UBX-RXM-RAW message includes carrier phase with half-cycle ambiguity resolved, code phase and Doppler measurements, which can be used in external applications that offer precision positioning, real-time kinematics (RTK) and attitude sensing.

LEA-6 modules are rated at MSL level 4. For more information regarding moisture sensitivity levels, labeling, storage and drying see the u-blox Package Information Guide [3]. For MSL standard see IPC/JEDEC J-STD-020, which can be downloaded from www.jedec.org. 6.3 Reflow soldering Reflow profiles are to be selected according to u-blox recommendations (see LEA-6/NEO-6/MAX-6 Hardware Integration Manual [1]). 6.4 ESD handling precautions LEA-6 modules contain highly sensitive electronic circuitry and are Electrostatic Sensitive Devices (ESD). Observe precautions for handling! Failure to observe these precautions can result in severe damage to the GPS receiver! GPS receivers are Electrostatic Sensitive Devices (ESD) and require special precautions when handling. Particular care must be exercised when handling patch antennas, due to the risk of electrostatic charges. In addition to standard ESD safety practices, the following measures should be taken into account whenever handling the receiver: * Unless there is a galvanic coupling between the local GND (i.e. the work table) and the PCB GND, then the first point of contact when handling the PCB must always be between the local GND and PCB GND. * Before mounting an antenna patch, connect ground of the device * When handling the RF pin, do not come into contact with any charged capacitors and be careful when contacting materials that can develop charges (e.g. patch antenna ~10pF, coax cable ~5080pF/m, soldering iron, ...) * To prevent electrostatic discharge through the RF input, do not touch any exposed antenna area. If there is any risk that such exposed antenna area is touched in non ESD protected work area, implement proper ESD protection measures in the design. * When soldering RF connectors and patch antennas to the receiver's RF pin, make sure to use an ESD safe soldering iron (tip).
