1. Introduction This is the user manual for eSurveys’ E800 GNSS receivers. It gives a basic description and operational guide which may help users to operate the device in a proper manner. 1.1 Appearance The E800 main body is designed with magnesium alloy material to provide durable usage and better heat dispersion.
1.3 Interface E800 GNSS receiver’s bottom interface is shown below. The 5-pin port is used to connect to the external radio, external power or output NMEA messages. Type-C port can be used for data download (internal storage access) or charging.
“self- check”. 1.6 Touch Screen E800’s 1.45” colorful screen is touch enabled. Users can view device status or operate the device via touch screen. The screen includes three parts: the main page, device information and work mode setting.
PDOP Limit Base ID: Change from software Rover Change to rover setting Channel: Channel frequency Radio Power: Low(2W)/High(5W) Protocol: Radio Protocol Datalink GPRS Auto APN: Yes/No External Radio Baud Rate Diff Diff Mode Available in base mode Backlight Time Setting Setting Language: wait for 3 seconds to apply setting 2.
2.2 Satellites View satellite list and satellite map, set cut-off angle. 2.3 Information View receiver information: firmware version, GNSS board, and network module. 2.4 Working Mode Configure working mode: base, rover or static.
2.5 Satellite Setting Configure the satellites to be used. 2.6 Device Configuration Configure receiver settings: User can set the time zone. Sensor means MEMS sensor data output. Also, the 5-pin port baud rate is changeable. Speaker “Smart voice broadcast” can be disabled. Base Alert is enabled, the rover will receive message when base is moved.
2.8 View Logs The log files can be used to diagnose issues. Click “download” to download the files. 2.9 Raw Data Download raw data or convert data to RINEX format. Users can use the check box, then click “Package” to download multiple files. 2.10 Backup Data The points collected in SurPad4.0 software can be backed up in receiver storage automatically to avoid data loss.
E800 supports network working mode. Open the cover and insert Micro SIM card. 3.2 Charge the battery E800 is equipped with a Type-C charger which supports a maximum of 45W PD quick charge. The capacity is 13600mAh, Fully charging the battery takes 8 hours typically.
3.3 Attach radio antenna A antenna is required in radio working mode. 3.4 Measure antenna height In order to get correct elevation value, we need to know the correct phase center height of the receiver. However, it is almost impossible to measure the phase center directly.
3.5 Tilt Survey E800 is equipped with MEMS sensor which supports tilt survey in SurPad4.0 software. The calibration is very simple. To calibrate the MEMS sensor, receiver must be in Fixed solution. In SurPad4.0 software, connect device and click “Device” -> “Device Settings”, open “Pole Tilt Correction”...
4. Internal Radio E800 is equipped with 5-watt internal radio. Users can select the transmission power of 2W (Low) or 5W (High). There are 8 default channel frequencies and the frequency of the channel “8” is adjustable. With new firmware update, many of the main survey industry protocols are supported.
"performance failure”, which still isn’t in working condition after two repairs. e-survey supports a 24 months of warranty service for a device host and a 3 months of free warranty service for an accessory from the day when the products are received.
