A:1.Check the tracked satellites and the Age of Differential

2.Check the IMU alignment

3.Pre-validate tilt compensation: measure a point, re-stake it, and ensure the stakeout error ≤ 2 cm before switching to laser mode.

A: Both metrics can be read directly in the upper-left corner of the software: maintain ≥ 25 usable satellites and keep the differential age ≤ 3 s (ideally locked at 1 s).

A: A dedicated IMU-status icon on the tilt-measurement panel reports whether the inertial subsystem is aligned and ready for use.

2. Exclude intense ambient light.  

3. Skip severe weather (heavy rain, fog, snow).  

4. Steer clear of high-rise canyons.

A: Initialize every time you enter the laser-measurement screen:
1. IMU Initialization—rock the pole gently back-and-forth;
2. Laser Initialization—verify the distance read-out is live, then walk for 5–10 m straightly.

A: 1. Time window: complete the shot within 15 s of initialisation; re-initialise if exceeded.

2. Range limit: keep target distance ≤ 5 m to hold 2.5 cm precision.

3. Spot stability: make sure the laser point is stably aimed at the point to be measured without shaking.

4. Avoid pole-slam: do not strike the ground violently with the pole tip.

5. After IMU power-on, hold the pole vertical for a few seconds so the IMU can lock its initial attitude.

6. Don’t let the pole sit idle for more than 15–30 s—IMU errors stack up fast.

A: 1. Compare the data of the same point measured by the point survey and the laser survey;

2. Use the tool “Inverse Calculation” to calculate the distance of two measured points. Then compare the data with that measured by the measuring tape. If the discrepancy stays within 2 cm, the measurement is considered accurate.

3. Re-verify the measured point via point-stakeout or laser-stakeout.

A: 1. Check the tracked satellites and the Age of Differential. Both metrics can be read directly in the upper-left corner of the software: maintain ≥ 25 usable satellites and keep the differential age ≤ 3 s (ideally locked at 1 s).

2. Check the data link which must be WIFI. It can be checked in the “Communication” interface.

3. Check the IMU alignment. Red instructions will appear when it can’t work.

A: 1. Avoid measurements in overly dark environments.  

2. Avoid measuring in extreme weather (e.g., heavy rain, dense fog, or snowfall).  

3. Avoid surveying near tall buildings.

A: Not recommended—running extra apps can monopolize the very resources photogrammetry demands and trigger mid-flight crashes or stuttering.

A: Circle the object as prompted and capture at least five images.

A: After capture, open the image gallery and pick a high-contrast point to save—select a pixel clearly different from its neighbors or the photogrammetric solve will likely fail.

A: 1. Compare the data of the same point measured by point survey and photogrammetry.

2. Use the tool “Inverse Calculation” to calculate the distance of two points measured by photogrammetry. Then compare the data with that measured by the measuring tape. If the discrepancy stays within 2.5 cm, the measurement is considered accurate.

3. Re-verify the measured point via point-stakeout.

A: Check if the surrounding environment meets the conditions for satellite signal reception; ensure the registration code is not expired; verify if there is regional restriction; make sure the satellite system is on; and check if the board firmware is correctly upgraded.

A: Connect the controller to the device hotspot and enter the website address 10.10.10.10 in the browser. Go to "Device Operation," input the registration code, then click "Register."

Method 1: Connect the controller to the device hotspot and enter the URL 10.10.10.10 in the browser. Go to "Device Operation," enter the custom code, and click "Write."
Method 2: Open the software of the controller, connect the device to Bluetooth, go to "Configuration," "Function Code Registration," enter the custom code, and click "Register."

Method 1: Connect the controller to the device hotspot and enter the URL 10.10.10.10 in the browser. Go to "Device Operation," enter the custom code, and click "Write."
Method 2: Open the controller software, connect the device to Bluetooth, go to "Configuration," select "Communication Settings," open Debugging, input the command "SET, FRESET, GNSS," and click "Send."

A: Check if differential data is obtained (check if the differential account is valid, if the device network is online, and if the radio protocol and frequency match the base station); ensure the satellite reception environment is good; and avoid use during thunderstorms.

A: Check if the base station started with fixed coordinates, and if the deviation between the fixed coordinates and the actual coordinates is significant. Suggest to obtain accurate fixed coordinates or switch to single-point coordinates to start up the base station.

A: Check if the device has a SIM card inserted; verify if the mobile network is on; and confirm if the CORS IP address, port, name, and password are correct and CORS account not expired.

A: Check if the device is properly inserted with a SIM card; verify if the mobile network is online; and confirm if the CORS IP address, port, name, and password are correct.

A: Re-insert and unplug the SIM card; restart the device; switch network format; input the correct APN name, username, and password; and check if the SIM card can access the internet.

A: Check if the built-in antenna is connected; ensure the radio protocol and frequency match the base station.

A: Check the PDOP limit and height cutoff angle; ensure the satellite reception environment is good; and avoid using the device during thunderstorms.

A: Log in to the website, go to "File Management," select the date and static raw data, and click to download.
