1 Get to Know Trion Survey

Trion Survey is a professional field surveying application designed for surveying and mapping, engineering construction, and GIS data collection. When used with GNSS/RTK receivers, it supports project and coordinate system management, receiver connection, point and line measurement, field drafting, point, line, and CAD stakeout, as well as data import and export. It also provides practical tools for area and volume calculation, coordinate transformation, and COGO operations. By integrating receiver configuration, data collection, field stakeout, and result export into a single platform, Trion Survey helps users complete a wide range of high-precision field tasks more efficiently.

FOUR CHECKS BEFORE WORK  Correct project, receiver connected, solution FIXED, and Antenna Height correct.

2 Connect a GNSS Receiver

PATH: Settings  >  Connection

Establish stable communication between the controller and the intended RTK receiver.

1. Power on the receiver; set Device Type to RTK in Connection.
2. Choose Bluetooth or Wi-Fi and refresh the device list.
3. Identify the receiver by the last five digits of its SN, select it, and tap CONNECT. Follow the Android pairing prompt for first-time Bluetooth; the default Wi-Fi password is 12345678.
4. After the app returns home, confirm that receiver SN, satellites, battery, and position values keep updating.

3 Create a Project

PATH: Projects  >  Projects  >  NEW

Create a separate data container for the job so records are not mixed with another project.

1. Enter a clear name, such as Project_Date.
2. Select the project Coord System; add a Code Template and External Data only if needed.
3. To reuse an existing setup, enable Copy Project and select the source project.
4. Tap SAVE, return to the project list, and confirm that the new project is current.

DONE WHEN  The correct project name appears at the top of Home. Points, lines, CAD, and exports will be stored under this project.

4 Set the Coordinate System

PATH: Projects  >  Coord System

Use one spatial reference for field observations, design data, stakeout, and exports.

1. Prefer Predefined and search by region, name, or EPSG code; Trion Survey includes more than 6,000 predefined systems.
2. Open Details and verify the ellipsoid, projection, central meridian, coordinate units, and vertical datum.
3. Use a Custom system only with approved parameters; load transformation, geoid, or grid models when required.
4. Apply the system, then remeasure a known point and verify horizontal and vertical differences.
5. Site Calibration and Base Shift are both common tools for coordinate system setup.

5 Configure the Rover

PATH: Settings  >  Rover  >  NEW

Assuming the base station is already set up, select the correction source and keep correction data flowing to the rover.

1. Choose a method—commonly Ntrip, Internal Radio, or FDDS.
2. Ntrip: enter Network, IP, Port, Source Node, Username, and Password, then tap APPLY.
3. Internal Radio: match protocol, baud rate, channel/frequency to the base and attach the correct-band whip antenna.
4. FDDS: enter the six-digit base code and apply; return Home and wait for FIX.

Once the rover is configured, before saving any points, make sure the positioning status meets the project's quality requirements.

6 Measure Points

PATH: Survey  >  Measure

Collect and save an individual coordinate while the solution is FIX.

1. Enter Point ID, choose the correct antenna type, enter Antenna Height, and select a Code if required.
2. Place the pole tip precisely on the point, center the bubble, and keep the pole steady.
3. Confirm FIX and acceptable HRMS/VRMS, then tap Measure. Investigate an over-limit warning before accepting it.
4. Open Points and spot-check Point ID, Northing, Easting, Elevation, and point type. Remeasure a known point first.

7 Measure & Draw

PATH: Survey  >  Measure & Draw

Collect points while building line or polygon geometry in the field.

1. Select a point, line, or polygon Code; tap the line-type tool and choose one of the ten geometry types.
2. Measure nodes in sequence as prompted; a dashed preview connects the current position to the last node.
3. Use Back to remove a wrong node. A polyline can finish with at least two nodes and can close with at least three.
4. Tap Finish; the geometry is named and saved to the graphics library. Check its shape, Code, and attributes.
5. When required, export graphics to SHP and choose whether to merge or keep individual features.

8 Stake Points

PATH: Survey  >  Stake Points

Navigate from a design coordinate to its field location and save the as-staked point.

1. Select one or more stake points. A red flag marks the target; use Previous, Nearest, and Next for multiple targets.
2. Follow relative or cardinal guidance. The bullseye appears at 1 m or less.
3. Recheck Antenna Height and elevation mode. If the target has only plane coordinates, use real-time elevation when appropriate.
4. Under FIX, center precisely; when the job tolerance is met, tap Measure to save the as-staked position.

9 Stake Lines

PATH: Survey  >  Stake Lines

Stake stations along a design line, find the nearest line position, or stake key nodes.

1. Select a line from Lines or create a straight line/polyline in the field.
2. Choose Station, Line, or Node mode: regular chainage points, nearest position to line, or key nodes.
3. For stations, set Start Chainage, Interval, left/right Offset, Target Chainage, and Include Nodes as required.
4. Use chainage and lateral offsets in the navigation panel; save under FIXED when the tolerance is met, then move to the next target.

10 Stake CAD

PATH: Survey  >  Stake CAD

Load a DWG/DXF design, select targets from the drawing, and stake them directly.

1. In CAD Files, tap Import and add the DWG/DXF from the controller to the current project.
2. Open the drawing and verify location, units, Coord System, and layers; hide irrelevant layers for smoother operation.
3. Open Stake CAD and snap to a point, line, or node. A line target supports Station, Line, and Node modes.
4. Set target elevation and any station/offset values, navigate to the target, and finalize under FIXED.
5. Save the as-staked point and review both target and measured data in the layer/point library.

11 Import Data

PATH: Projects  >  Import

Bring external points or industry data into the current project safely.

1. Choose Text Format or Other Format. Text formats include CSV, TXT, DAT, XLS, and XLSX and support editable field mapping.
2. Select or create a format; confirm delimiter and mappings for Point ID, Northing, Easting, Elevation, and Code.
3. Set points intended for stakeout as Stake Points and choose the duplicate-name rule carefully.
4. Select a file from local storage, USB, My Cloud Drive, or a sharing code and run the import.
5. Verify record count, Point IDs, coordinate magnitude/range, and map location after import.

12 Export Data

PATH: Projects  >  Export

Output the required coordinate file and verify it before leaving the site.

1. Select a Text Format or standard format, then set point type, time range, Code filter, and sort order.
2. Confirm field order, units, decimals, file name, and local/USB/cloud destination.
3. Run Export. For collaboration, upload to My Cloud Drive or create a sharing code.
4. Reopen the file and verify point count, header, first/last records, and two or three sample coordinates.
