High Precision Gnss GPS Receiver Foif A90 with 1408 Channels

 Product Description 1) Smart DesignWith the increasing demand for smart-design GNSS, to develop the receiver featured with miniaturization turns into our new goal until today it comes true. It is completely no doubt that small size and light weight design can greatly alleviate general field work and improve productivity a lot.  2) Brand new ideaIn terms of cellular mobile and wireless system, we tend to introduce more and more creativities into our product. Besides a set of bluetooth, wireless radio and mobile network, we bring in the WIFI function which quite broaden data communications for GNSS.  3) Excellent performanceEmbedded with high-sensitivity GNSS module , A90 can implement massive surveys:RTK, DGPS, (SBAS) , Static, etc.  Product ParametersTypeA90GNSS System800 channelsPerformanceStatic measurement plane accuracy±(2.5mm + 0.5ppm)RMSStatic measurement elevation accuracy±(5mm + 0.5ppm)RMSRTK measurement plane accuracy±(8mm + 0.5ppm)RMSRTK measurement elevation accuracy±(15mm + 0.5ppm)RMSSBAS postion(typical)0.5mInitialization time99.99EnvironmentWorking temperature-30ºC~ +60ºCStorage temperature-40ºC~ +80ºCWater-proof & Dust-proofIP68Drop resistance2 meters at normal temperatureHumidityAnti-condensationStorage/dataBuilt-in storageOnboard 8G, Support TF card expansion≥32GDifferential outputRTCM2.3, RTCM3.X, RTCM3.2, CMR, CMR+,RTCAData safetyData will be stored and backed up in three places after surveyingSatellite AntennaHigh performance 4 in 1 antenna: GNSS antenna/Bluetooth/WIFI/4G full netcom module is highly integratedWireless communicationBluetoothBuilt-in V2.0 Class2WIFIDirectly connected to the handheld controller via wifi instead of bluetooth, support web UI wireless management: device upgrade, data download, parameter setting, station operation, etc.Communication protocolPCC-EOT, TrimTalk 450S, TrimMark III,South,GeoTalk,GeoMark,Satel,HI-TARGET,ect.UHF radioBulit-in transceive0.5/2W Effective distance≥5kmExternal transmit2/35WEffective distance≥15kmWorking Frequency410-470MHzPhysical and Power CharacteristicsSizeΦ15.6cm×7.6cmMaterialLower cover is magnesium alloy, Top cover is polymer plasticBattery volume7.4V×3700mAH×2, Intelligent lithium battery, self power displayUser interface4 LED indicators, 1 button,voiceWorking time>8 hoursAuxiliary functionElectronic bubble, 2nd generation tilt survey function  Detailed PhotosCertificationsFactory Photos Our Products /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
