Ublox Chip Set GPS Smart Antenna Module Low Power Consumption

The DL-1818N-GCUFmodule series isa family of stand alone GPS receivers featuring the high performance u-blox 7 positioningengine. These flexible and cost effective receivers offer numerous connectivity options in aminiature 18.1x18.1x6.4mm package.Their compact architecture and power and memory options make DL-1818N-GCUFmodules ideal for battery operated mobile devices with verystrict cost and space constraints.The 56-channel u-blox 7 positioning engine boasts a Time-To-First-Fix (TTFF) of under 1 second. The dedicated acquisition engine,with over 1 million correlatorsis capable of massive parallel time/frequency space searches,enabling it to find satellites inst antly. Innovative design and technology suppresses jamming sources and mitigates multipath effects, givi ng DL-1818N-GCUFGPS receivers excellent navigation performance even in the most challengin g environments.DL-1818N-GCUFmodules are not designed forlife saving or supporting devices or for aviation and should not be used in products that could in any way negatively impact the security or health of the user or third parties or that could cause damage to goods.ApplicationsLBS (Location based Service)PND (Portable Navigation Device)Vehicle navigation systemMobile phoneFeaturesBuildonhighperformance,low-poweru-bloxUBX-G7020-KTchipsetUltrahighsensitivity:-165dBmExtremelyfastTTFFatlowsignallevelBuiltinhighgainLNABuilt in SPI FLASH,Used to save configuration commandsLowpowerconsumption:Max35mA@3.3VNMEA-0183 compliant protocol or custom prot ocolOperatingvoltage:2.8V--3.6VOperatingtemperaturerange:-40to85ºCPatchAntennaSize:18mmx18mmx4mmSmallformfactor:18.1x18.1x6.4mmCommunication type: UART/TTLRoHScompliant(Lead-free)ParameterSpecificationPowerSupplySupply voltage: 2.8V~3.6V Typical: 3.3VPowerConsumptionAcquisition: 35mA @VCC=V_BCKP=3.3VTracking: 30mA @VCC=V_BCKP=3.3VBackup: 15uA @V_BCKP=3.3VReceiver TypeCode 56 search channels ,22 synchronous tracking channelsGPS&QZSS L1 1575.42MHz C/A ,GLonASS L1OF 1602MHz,SBAS: WAAS, EGNOS, MSAS, GAGAN
