- Page 5 3、 Guide For Outdoor Surveying The following instructions are easy-to-follow tips for new surveyors. For detailed guidance,please read the user manuals. (Note:The manuals can be downloaded on the official website:alpha-survey- ing.com) 3.1 General Working Process Of Base & Rover: (1) Set up the base.
- Page 6 (5) Go to another known point to check whether the coordinates are right after coordinate transformation. (6) Start the work. *If the start-up coordinate or the position of the base station change, you need to perform a maker point calibration process. (7) Finish the work and export the data file as required.
- Page 7 Requirements of the place you set up the base： Requirements of the place you set up the base： a. Cut-off angle larger than 15 degrees; Open area a. Cut-off angle larger than 15 degrees; Open area without large obstructions. without large obstructions. b.

Click the positioning button to get the local central meridian in the Projection interface of the Coordinate system setting.

- Page 10 【Network of the instrument】 The mode is connected to the Internet by the network of RTK. Open the rover mode interface, click[New] to create a new config set. As for the data link, select the NETWORK,connection mode As for the CORS setting, “...
- Page 11 【Network of the controller】 Insert the SIM card into the controller, and select PHONE in the data link, the same way as setting network for the instrument. In general, when the rover gets differential solution and fixed solutions successfully, it is suggested that the rover has been set up.
- Page 12 3.2.5 Calculating Transformation Parameters Taking four parameters as an example, the operational steps are as follows:： 1、 Get fixed solution by setting the mobile station properly. Click [Survey]- [Point survey] to get the coordinates of two known controlling points. Known controlling point: Northern :2909040.268 Eastern :480802.662 Altitude: 11.901...
- Page 13 3、 Repeat the above operation and add another point. When two points are recorded, the coordinate calculation can be done. Then switch back to the transforma- tion parameters interface and click [calculate] at the bottom, you will get the transformation parameter results.
- Page 14 3.2.6 Data Exporting When the measuring work is finished, the results can be exported in the format that caters to the needs of the surveyor by clicking [project]-[data export]. The export process is as follows. a. Connecting the controller to a computer by Type-C cable. Set USB computer connection to MTP mode.The computer will read the U disk mode in the controller, open and copy the recorded results on the computer.
- Page 15 Click [Project]-[panning and calibration] and employ the 4、 Tilt compensation Alpha 5i with the inertial navigation system is able to offer accurate inertial measurement in real-time even in the condition of high inclination or in highly dynamic situations.
