Galaxy G6 Chapter Ⅶ Measuring Operation Reading this chapter, you can grasp in detail how to use the G1 measurement to do system static, RTK operations. GPS measurement operation scheme refers to the operating scheme used to determine the relative position between the stations with the help of GPS technology. Point coordinate precision obtained is not the same; its operating methods and observation time are also different, thus having different range of applications.
Galaxy G6 The establishment of precision engineering control network, such as bridge measurement, tunnel measurements, etc; The establishment of a variety of encryption control network, such as city measurements, Drawing Point measurement, road surveying, demarcation measurements.
Galaxy G6 5)Power on, confirm the static mode, the mainframe begins to search satellites and satellite lights begin to flash. Recording condition reached, the status light flashes in accordance with the set sampling interval, flashing once indicates the acquisition of an epoch. 6)After the test, the mainframe shut down, and then begins data transmission and data processing (data transmission sees Chapter IV, data processing, please read another manual GPS data processing software operation manual). §7.1.
Galaxy G6 and consistency. General speaking, the amount of baselines has such limit as follows: The advantage of circle net is the small workload, good self-checking and consistency. But the main disadvantage is that the accuracy of indirect-observed border is lower than that of direct-observed border, and the baseline accuracy of neighbor points distributes unevenly. In field surveying, we usually use annexed traverse as special example according to practical situation and the net usage.
Galaxy G6 Measuring plate h We use a formula to calculate antenna height. “h” is the inclined height that measure from point on the ground to the measuring plate edge. R0 is the distance from middle of antenna to the edge of measuring plate. h 0 is the distance from antenna phase center to the bottom of receiver (measuring plate). H is the calculation result. We usually measure antenna height twice and adopt the average.
Galaxy G6 §7.2 RTK measurement RTK is the abbreviation of Real-Time Kinematic measurements. RTK technology is the real-time dynamic differential carrier phase positioning technology, combining global satellite navigation and positioning technology with data communication technology which includes base station and rover station.

Then select the appropriate one from the list and click on “Enter” button at the bottom to access.
Galaxy G6 §7.2.4 By using internet (WIFI) WiFi datalink is a new feature and new technology adopted on Galaxy G6, it is more faster and stable in network RTK job. Set the receiver as rover with WIFI mode on the control panel or on Web UI. Instrument settings 1) After choosing the rover mode for receiver, then press F button and get into the “Set Data Link” configure page, then move the select box to “WIFI Datalink” option and press power button to confirm.
Galaxy G6 Web UI settings 1) Login the web UI of G6 and go to “General Config” interface, then choose “WIFI” in “Datalink” option, click on “Enter” button to confirm and save the settings. 2) Then go to “WIFI Config” interface under “Network Config”, there the option of “Client” is activated if WIFI used as datalink.
Galaxy G6 4) If the WIFI connection is successfully connected, go to “NTRIP Config” interface under “Data Transfer”, and input the CORS server information including IP, Port, User and password, then click “Get Point” button to download mountpoint list from server. Then select the appropriate one from the list and click on “Enter” button at the bottom to access.
Galaxy G6 §7.2.5 Tilt Survey Electronic Bubble Start electronic bubble a) In the main interface, click the calibration setting button on the top of the interface, then get into the setting interface. b) Mark on the checkbox of “Bubble” option in the setting interface, click „OK‟ return to Point survey interface, there appears the electronic bubble on the upper left of the screen.
Galaxy G6 Sensors Calibration Galaxy G6 supports tilt survey function, but before doing the tilt surveying on Galaxy G6, the sensors calibration shall be done. 1. Electronic Bubble calibration Get into calibration interface by clicking on calibration setting button on the top of the screen. Click “Electronic Bubble” in the calibration setting interface, In the acceleration calibration interface, make sure the device is level, hold and click “Start” button to start the calibration, until it‟s finished.
Galaxy G6 2.Magnetic calibration In the calibration setting interface, click “Magnetic” to enter the magnetic calibration interface. In the megnetic calibration interface, click “Start” to start the calibration, then flip and rotate the G6 according to the sketch map on the left bottom of the screen ( you can also draw “∞” after G6 is connected to the carbon fiber pole), until the calibration is finished 100%.
Galaxy G6 Tilt Surveying After finishing the calibration for sensors, you can start tilt survey with Galaxy G6 in the tough conditions such as under the eave or around the wall, this function can correct the slant coordinates to the normal coordinates within 30°angle of inclination. SPECIAL REMIND: We recommend you to do the measurement in usual way with the pole centering in the open air area, the tilt survey function is not the mainly measuring method for the normal fieldwork. §7.2.

Galaxy G6 Appendix C Technical Terms Ambiguity: unknown quantity is the integer number of cycles of the carrier phase measured from the satellite to the receiver. Baseline: The connection line of the two measurement points, on which to receive GPS signals and collect observation data simultaneously. Broadcast ephemeris: message released by the satellite demodulator satellite orbit parameters. SNR (Signal-to-noise ratio): an endpoint signal power to noise power ratio.
Galaxy G6 Multipath error: the positioning error caused by the interference between two or more radio signal propagation path. Observing session: the use of two or more receivers at the same time to collect GPS data period. Pseudo Range: GPS receiver in the time required to copy the code aligned with the received GPS code offset and multiplied by the speed of light to calculate the distance.
