List of common software problems and solutions
1. Pre-operation checks for laser measurement.
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.
2. How to check the tracked satellites and the Age of Differential?
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).
3. How to check the lMU alignment?
A: A dedicated IMU-status icon on the tilt-measurement panel reports whether the inertial subsystem is aligned and ready for use.
4. What's the site selection criteria for reliable laser measurements?
A: 1. Avoid targets with extremely low (e.g., black) or high (mirror) reflectance.
2. Exclude intense ambient light.
3. Skip severe weather (heavy rain, fog, snow).
4. Steer clear of high-rise canyons.
5. How to do the initialization of the laser measurement?
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.
6. How to secure centimeter-level accuracy in laser surveying?
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.
7.How to verify the accuracy?
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.
8. Pre-operation checks for photogrammetry.
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.
9. What's the site selection criteria for reliable photogrammetry?
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.
10. Can other applications be run concurrently during photogrammetry measurement?
A: Not recommended—running extra apps can monopolize the very resources photogrammetry demands and trigger mid-flight crashes or stuttering.
11. How to use the photogrammetry properly?
A: Circle the object as prompted and capture at least five images.
12. How to select the suitable points during photogrammetry?
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.
13. Pre-test before photogrammetry.
A: Before photogrammetry, validate tilt compensation: measure a point and re-stake it; if the residual ≤ 2 cm, the tilt sensor is ready.
14. How to check the accuracy after photogrammetry?
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.
15.The device cannot receive satellite signals.
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.

19. Fixed solution is not possible.
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.
20. The device prompts that the base station startup coordinate deviation is too large.
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.

List of common software problems and solutions
1. Is it necessary to insert a SIM card while using the SAG10?
A: Only using the Cors mode requires the SIM card to work. In the PPP or radio mode, it doesn’t require the SIM card.
2. How to judge if the GNSS receiver can work with the SAG10?
A: Due to variations in interfaces, software, and configurations across manufacturers, the SAG10 should be matched with our brand’s GNSS receivers to prevent malfunctions caused by incompatibility.
3. After travelling 10 m along the set A-B line and turning, the tractor’s path is off the line. Is it necessary to manually drive the tractor to realign with the AB line and go back to point A?
A: Yes, it is.
4. How to adjust the dimensions?
1.After the AB line has been created, engage auto-steer at point B and let the tractor crawl forward until the cross-track error on the display reads 0/1. Stop immediately, place a physical marker exactly under the rear-axle centre, measure the distance from the marker to the inside of the left rear rim, and log the value.
2.Disable the navigation, manually move the vehicle forward a short distance, then make a U-turn. Manually steer the vehicle back toward the AB line. Once aligned, re-enable the navigation and return to the marked position. Stop and measure the distance from the marker to the rear wheel again.
3.Compare the difference between the two measured values. If the difference is within 2 cm, and the straight-line deviation shown on the tablet software is also within 2 cm, no adjustment to the antenna parameters is necessary. If the difference exceeds 2 cm (e.g., 4 cm), an adjustment is required. For example, if the initial measurement at the left wheel is 50 cm, and after the U-turn the measurement becomes 54 cm, this indicates that the antenna may actually be mounted to the right of the center-line. In this case, adjust the antenna offset setting in the tractor system to 0.02 m to the right, indicating to the software that the antenna is offset to the right.
(If the result of a single round trip is not trusted, the user may repeat the above process multiple times to verify the measurements.)
5. How many GPS, Bluetooth, Wi-Fi, and 2/3/4G wireless modules are contained in the complete Auto-Steer SAG10 kit, and are the wireless modules identical?
A: 1 GPS module, 1 Bluetooth module, 1 Wi-Fi module, and 1 module for 2/3/4G which is identical.
6. Is it necessary to define the reference plane before using the Map Collection function?
A: No. You can directly perform the map collection, and after the map collection is completed, an average reference surface will be calculated automatically.
7. Can a camera be installed in the land leveling system software?
A: Yes. The wiring harness of the land leveling system has a reserved interface for a camera, so a camera can be installed if needed.
8. What’s the function of the relief valve?
A: By controlling pressure and flow, it ensures the stability and safety of the system. For example, when the system pressure exceeds the set value, the relief valve will automatically open to prevent hydraulic components and pipelines from being damaged by high pressure.
9. In the complete TAG88 product set, how many GPS, Bluetooth, Wi-Fi, and 2/3/4G wireless modules are there? Are the wireless modules the same?
