Positioning IssueThe number of satellites shows 0Environmental reasons, hardware reasons1. Check whether the GNSS antenna is blocked or interfered with.
4
2. Check whether the GNSS antenna and wiring harness are normal.
5
3. Check whether the GNSS antenna harness is connected correctly
6
4. Change terminal FOR cross-verification/check

Data Source Status/Data broadcast status is abnormalData source configuration, operation , and hardware1. Check whether the data source is configured and used correctly
10
(HD201 portable base station, cors configuration, PPP, Fixed base station)
11
2. Data source cover range
12
3. Check if the radio antenna is installed
13
4. Cross-validation by changing the same kind data source
14
The differential delay is too large, not 1.0/0.0 or 0.0/0.0Data source configuration reasons, hardware reasons1. Check whether the terminal and data source channels are consistent/matched
15
2. When Cors is configured, check whether the network is normal. (CORS needs internet)
16
3. Is the radio antenna installed?
17
4. Cross-validation by changing the same kind data source
18
GPS positioning not fixedSingle PointNetwork issueConnect to mobile hotspot or replace SIM card
19
Satellites: normal around 28
20
Latitude and longitude: normal
21
Data Source Status: Server connection fails
22
Location: direction not fixedGNSS antenna issueCheck connection cables, replace GNSS antenna
23
Satellites: 0
24
Latitude and longitude:0
25
Data Source Status: normal
26
Single PointCORS account issue (RTK service)Contact tech support to change CORS account,reset GNSS board
27
Satellites: around 28
28
Latitude and longitude: normal
29
Data Source Status: Account authentication failed
30
Location: Single point (Radio base station connected)
Recevier board and Radio base station mismatchReplace the correct radio base station or connect to internet/hotsopt to upgrade the radio base station
31
Satellites: around 28
32
Latitude and longitude: normal
33
Data Upload: Server connection fails
34
Swath Transition/Swatch gap IssueThe swath gap on both sides are fixed but the values are wrongThe position of the implement is not centered relative to the agricultural machinery, and the implement parameters are incorrectly filled in.Adjust left and right offset(in Farm implement parameters), Adjust the connection between the tractor and the implement, left or right
35
36
37
The autosteer will not make the tractor go in a straight lineFarm implement parameters, scenarios, and hardware reasonsLateral is normal
38
1. IMU/Receiver vibration (Attatch IMU directly to floor, not on top of floor mat)
39
2. Loose GNSS antenna
40
3. IMU and wiring harness failure
41
4. Too big implements Backlash/Free Play/loss
42
5. Terrain reasons
43
6. Inaccurate input of implement parameters
44
Abnormal lateral error
45
1. Motor and wiring harness abnormality
46
2. Vehicle steering abnormality
47
3. Control parameters are incorrect
48
4. Gyroscope failure
49
5. IMU and wiring harness failure
50
Connection AbnormalityStatus bar shows: SIM card 1 status XSIM card not insertedCheck whether SIM is inserted correctly
51
Status bar shows: Gyroscope not connectedGyroscope not connectedCheck gyroscope and cable connections
52
Status bar shows: IMU abnormalIMU not connected or damagedCheck IMU and cable connections
53
Status bar shows: Motor connection abnormalMotor not connected or motor model mismatchCheck motor and cable, or change to correct control model
54
IMU IssuesAfter vehicle calibration, Going back and forth on the same navigation line,cannot stay on a straight line; deviation appears;IMU not fixed
Re-fix IMU, ensure no obstruction above and no metal interference around
55
During normal operation, after turning, There are a lot of small S-bends on the operation trackIMU loosenedCheck and refix IMU
56
Swatch gap not fixIMU loosenedCheck and refix IMU
57
Usage IssuesDuring use, it reports: AutoSteering is not available, control status is idleConnection problemCheck the terminal's all harness connection and motor harness
58
When the vehicle is parked for a long time during use, the direction angle error is reported when the user starts the autosteer againGyroscope is SleepingRestart control box
59
Motor turn the steering wheel all the way to the left/right.The vehicle is spinning in circlesMagnetometer anomalyAfter recalibrating the magnetometer, restart
60
When the autopilot is activated, the vehicle keeps turning left and right, and the Swatch gap is constantly changing.Control parameter issueAppropriately reduce the heading sensitivity and increase the steering attack adjustment(How often the motor turns the steering wheel)
61
During operation, front wheels wobble; overlap varies within a certain rangeControl parameter issueAdjust steering sensitivity and increase turn gain
62
When the product is powered on, the vehicle is moving forward and WAS cannot be initializedPositioning State is not FixCheck the signal source,cors coverage, whether do the reset the GNSS BOARD
63
Gyro brokenReplace gyroscope with the gyro cable
64
Speed lower than 1.6km/h(1mile/h)speed up 2-3km/h 2mile/h (does not recognize machine is moving)
65
Magnetometer ProblemRecalibrate Magnetometer
66
Motor control status is abnormal, The motor has no torque，
The motor has low torque		Motor configuration reasons, hardware reasons, version reasons1. Check whether the motor and motor harness are normal
67
2. Check whether the motor control type selection is normal
68
3. Check if the motor calibration is correct
69
4. Check if you have the latest software version
70
71
The terminal has not been initialized after starting up.Driving speed is too low, hardware reasons,1. The vehicle need faster than 1.6 km/h =1 mile/h
72
2. Check whether the positioning status is normal
73
3. Check if there is any abnormality in the status bar. If there is, check if the wiring harness connection is normal. If the connection is normal, replace the hardware according to the abnormal prompt in the status and cross-check (gyroscope and wiring harness, IMU and wiring harness)
74
Frequent crash when opening navigationData caching reasonsClear the app cacheClick round icon in the black task bar at the bottom of the screen,slide the screen up from bottom to the top, go to settings, find the Applications page, Click NavTerminal, Find Cache, Click clean the cache.
75
Control box not connectedVersion, hardware reasons1. Check if you have the latest software version
76
2. Change other terminal to cross-verification
77
SoftwareWhen the new device is turned on, the factory test interface is displayed, and there is no autosteering appAndroid setup issuesAndroid system settings - privacy - workmode changed to 0
