LRTK app required to use LRTK terminals.

Basic usage is free, but you can use various functions that change the conventional positioning with a paid plan.

From free features to paid features, we'll show you everything you can do with the LRTK app.

* All paid functions can be used for a monthly fee of 30,000 yen (excluding tax).

​ *Paid features can only be used with LRTK Phone and iPhone at the same time.

​ [Free function]

​① Single point positioning

It is a function to locate a single point.

The LRTK app allows you to subtract the length of your tripod or red/white pole as an offset.

​ data can be checked from the LRTK app or on the synchronized LRTK cloud.

​Example: LRTK Cloud

You can check all the information for positioning, such as latitude, longitude and height.

​Coordinate information can be downloaded as csv or pdf. ​

​② Logging (continuous positioning)

It is a function that keeps positioning at 10 Hz (10 points per second).

By continuing logging while moving, it is also possible to capture the trajectory of movement.

The trajectory becomes a profile when viewed from the side (parallel to the ground).

​Example: LRTK Cloud

You can check the information of all the points that have been positioned.

You can also check the trajectory of the movement on the map.

​Coordinate information can be downloaded as csv or pdf. ​

​ [Paid features]

​③ Indoor positioning

This is a function that performs positioning with centimeter accuracy indoors.

Both single point positioning and logging are possible.

Error accumulates at approximately 1% of traveled distance.

For example, if you move 100m indoors, there will be an error of 1m at 100m ahead.

Azimuth correction is required before positioning. ​

Follow the prompts displayed on the LRTK app.

​ *Accuracy will decrease in environments with excessive shaking, low light, or when the camera is covered by your hand.

​④ Positioning photo

This is a function that replaces the coordinate information of the photographed photo with RTK accuracy.

​ coordinates will be the position of the iPhone camera.

It can be used for creating high-precision point cloud data by photogrammetry and for on-site inspection work.

​Example: LRTK Cloud

You can check all the information for positioning, such as latitude, longitude and height, as well as the photos you have taken.

​Coordinate information can be downloaded as csv or pdf. ​

​Photos can be downloaded as jpegs.

​⑤ Object positioning

It is a function to acquire the coordinates of the subject of the photographed photograph.

Only available for indoor positioning.

It can be used for positioning at points where positioning is difficult due to its shape, and for on-site inspection work.

​Example: LRTK app

​ You can get the coordinates of the center of the crosshair on the screen.

You can check all the information for positioning, such as latitude, longitude and height, as well as the photos you have taken.

​Coordinate information can be downloaded as csv or pdf. ​

​Photos can be downloaded as jpegs.

​ *Only available on iPhones with LIDAR.

​⑤ Object positioning
