High Precision Positioning Board

ER-306 & ER-307 OEM ModulesExperience Multi-Frequency Multi-GNSS RTKMain features:• Uses GPS, GLONASS and BeiDou; Galileo and QZSS ready• 372 Channels• Long-range RTK baselines• Compatible with ROX, RTCM, CMR, CMR+ RTK Sources• Fewer cold starts with Head Start• Pin compatible with many Hemisphere and other manufacturer’s modulesER-306 and ER-307Position with RTK accuracy using multiple satellite systems, ER-306 and ER-307 OEM modules use GPS, GLONASS and BeiDou and Galileo and QZSS are ready. Track more signals for unparalleled positioning performance even in challenging environments.Leverage the compact size and easy integration in your design. The 34 pin ER-306 module is a drop-in upgrade for many products. ER-307 is a drop-in upgrade for existing designs using standard 20 pin modules from other manufacturers.Scalable Eclipse RTK Solutions, with the Eclipse ER-306 and ER-307, RTK performance is scalable. Utilize the same centimeter-level accuracy in either single frequency mode, or employ the full performance and fast RTK over long distances with multi-frequency multi-constellation GNSS signals.EnvironmentalMechanicalCommunicationsGPS Sensor SpecificationsReceiver Type:GNSS multi-frecuency RTK with carrier phaseSignals Received:GPS, GLONASS, BeiDou, GALILEO 1and QZSS1Channels:372GPS Sensitivity:-142 dBmSBAS Tracking:3-channel, parallel trackingUpdate Rate:1 Hz standard, 10 or 20 Hz optionalAccuracy:Horizontal (RMS)  Vertical   (RMS)RTK:2 10 mm + 1 ppm  20 mm + 2 ppmSBAS (WAAS):3 0.3 m  0.6 mAutonomous, no SA:3 1.2 m  2.5 mTiming (1PPS) Accuracy:20 nsCold Start:4 < 60 s typical (all unknown)Warm Start:< 30 s typical (no ephemeris)Hot Start:< 10 s typical (all known)HeadStart:5 Removeable, auto-recharging onboard clock batteryMaximum Speed:1,850 kph (999 kts)Maximum Altitude:18,288 m (60,000 ft)Operating Temperature:-40°C to +85°C (-40°F to +185°F)Storage Temperature:-40°C to +85°C (-40°F to +185°F)Humidity:95% non-condensing (when installed in an enclosure)Shock: Mechanical Shock:EP455 Section 5.14.1 Operational (when mounted in an enclosure with   screw mounting holes utilized)Vibration:EP455 Section 5.15.1 RandomDimensionsP306:  71 L x 41 W x 13 H (mm)P307: 72 L x 41 W x 13 H (mm)Weight:< 23 g (< 0.81 oz.)Status Indication (LED):Power, GPS lock, Differential lock DGPS positionPower/Data ConnectorP306:  34-pin male header,   0.05" (1.27 mm) pitchP307:  20-pin male header,   0.08"(2 mm) pitchAntenna Connectors:MCX, female, straightSerial Ports:4 full-duplex 3.3 V CMOS (3 main serial ports,1 differential-only port),1 USB Host 6,1 USB DeviceBaud Rates: 4800 - 115200Correction I/O Protocol:Hemisphere GNSS proprietary, ROXFormat, RTCM v2.3, RTCM  v3.2, CMR,CMR+Data I/O Protocol:NMEA 0183, Crescent binary  7Timing Output:1PPS, CMOS, active high, rising edge sync, 10 kΩ, 10 pF loadEvent Marker Input:CMOS, active low, falling edge sync,10 kΩ, 10 pF loadPowerInput Voltage:3.3 VDC +/- 5%Power Consumption:< 2.55 W nominal dual frequency GPS+ GLONASS + BeiDouCurrent Consumption:770 mA nominal dual frequency GPS+ GLONASS + BeiDouAntenna Voltage: 15 VDC maximum Antenna Short CircuitProtection:YesAntenna Gain Input Range:10 to 40 dB
