Topographic Surveying Instrument Foif A90 with Hemisphere Board

Product DescriptionTopographic Surveying Instrument FOIF A90 with Hemisphere BoardFunction Feature   1. Compact design, more productive2. Professional GNSS satellites tracked simultaneously( GPS, Glonass, Galileo, Beidou)3. Automatic data collection during centering4. It could get the right point data by automatic correct system with IMU when the pole is tilted in 60 degrees.5. Applies WIFI connection to realize WebUI control designed to modify settings and monitor the receiver status6. Bundled Android field software brings a big change in user experience and accessibility  Function Feature1. Performance values assume minimum of five satellites, following the procedures recommended in the product manual,High-multipath areas, high PDOP values and periods of severe atmospheric conditions may degrade performance.*2. Long baselines, long occupations, precise ephemeris used.FOIF Geomatics CADMain functions include:DWG file format, compatible with AutoCAD Integrated transformation and grid system computationsFull 3D least squares adjustment, blunder detection, graphical elipse displayDTM contouring/Modeling volumes/3D renderingSite Design: Ponds, ditches, stockpiles and siopesRoad Design: horizontal and vertical alignments, cross sectional templatesCompletely customizable user interface* Toolbars-can be arranged with "drag and drop" functionality* Menus- can be re-organized with our graphical menu editor* Screen- items can be turned off for more graphics area* Layout- of command window- top or bottomReporting, exporting and printingProduct Parameters ItemsSpecificationGNSS EngineGNSS boardTrimble BD990 boardChannel336SatellitesGPS: L1 C/A, L2E, L2C, L5GLONASS: L1 C/A, L2 C/A, L3 CDMA14BeiDou: B1, B2, B313Galileo: E1, E5A, E5B, E5AltBOC, E614IRNSS: L5 SBAS: L1C/A, L5QZSS: L1 C/A, L1 SAIF, L1C, L2C, L5, LEXMSS L-Band: OmniSTAR, Trimble RTXTilt survey: The forth generation Tilt Technology, IMU functionReal-Time Accuracy(rms)SBASHorizon: 60cm(1.97ft); Vertical: 120cm(3.94ft)Real-Time DGPS positionHorizon: 40cm(1.31ft); Vertical: 80cm(2.62ft)Real-Time Kinematic PositionHorizontal: 1cm(0.03ft)+1.0ppm; Vertical: 2.5cm(0.08ft)+1.0ppmReal-Time PerformanceStop and Go solutionInstant-RTK Intialization Typically
