FJD Trion Survey App Introduction
Coordinate Transformation
Create various plane and elevation models with over 8,000 coordinate systems, 70 ellipsoids, and 30 projections. You can also handle geoid corrections to meet your regional needs.
Measure & Draw
Get accurate positioning data and measure/draw 10 common shapes (including polylines, circles, and rectangles). You can also make code-based measurements with clear graphic categories to speed up post-survey mapping.
Efficient Staking & Smooth Coordination
After you process data in the Survey App, you can add custom labels and quickly export it into common CAD files for fast field staking. You can also use the app to view road details like station equations, alignments, cross-sections, and slopes. Once you've confirmed the staking information is correct, you can export it as a LandXML road file for fast sharing and smooth coordination.
Adaptable for Global Use
By supporting 16 languages, the Trion Survey App lets you process terrain data collected from V4E in your preferred language. Plus, you can freely switch between landscape and portrait modes for better data display and viewing on the 8-inch UA80 and 10-inch D10. This simplifies your workflow from field to processing, quickly getting your data ready for the next project.

FAQs
Is this RTK receiver included with the Trion V4e LiDAR?
Yes. This RTK receiver is included with the Trion V4e LiDAR Kit.
What is the difference of V4e Standard and V4e Pro?
The V4e Pro builds upon the V4e Standard, adding laser range finding and tilt measurement for more advanced surveying needs, making it ideal for complex or precise projects.
How to upload the boundary created by V4e to the navigation system terminal?
Using the Survey APP or the corresponding App.
How to use this product?
A user manual is included with the product. You can also refer to the video.
Can V4e be used as a UAV (Unmanned Aerial Vehicle) base station?
No. Because V4e does not have a network module or a radio station.
Does V4e have a radio station?
No. It is recommended to use Ntrip (Networked Transport of RTCM via Internet Protocol).
How to upload the boundary and baseline data generated by V4e to the navigation kit terminal?
Create the baseline and boundary using the FieldFusion App, then select to sync them to the bound terminal.
When using the V4e Pro for laser measurement, the laser point jitters and cannot be stabilized. Are there any accessories to stabilize the device and ensure the laser point stays fixed on the measurement position?
V4e supports two measurement methods: (1) Inclinometer measurement with a centering rod, which meets the user’s need for stable measurement of specific points. (2) Laser inclinometer measurement, which is suitable for scenarios where users do not want to use a centering rod or where the centering rod cannot reach.
Currently, when V4e is used with Trion Survey, what is the compatibility like? Are there any important functions that are not yet supported?
Trion Survey APP is the supporting software for V4e, and there are no compatibility issues.
Can V4e be used in an environment with no network at all? And can it perform PPK (Post-Processed Kinematics)?
It is recommended to use V4e in an environment with a network. PPK is not supported.
Can V4e store RINEX (Receiver Independent Exchange Format) data?
No.
After connecting V4e Pro to FJD Trion Scan, what is the data format of the exported points?
.las (a common format for storing lidar point cloud data)
