4.1. אַלגעמיינע אינסטאַלאַציע טריט

1. Mount the 10.1-inch tablet securely in the cabin using the provided RAM bracket.
2. Install the EMS2 electric motor onto the steering wheel. Ensure the correct spline is used for your tractor model.
3. Attach the GNSS antenna to the highest point of the tractor cabin using the antenna mount plate.
4. Connect all necessary cables: Tractor Main Cable, Power Supply Extension Cable, Camera Extension Cable, Switch Cable, Switch Button Cable, and R71 Power Cable.
5. Install the Gyroscope Sensor Kit and Vehicle Radio Antenna as per the diagram.
6. Secure all cables using the provided rolling strips (cable ties).

This section outlines the key operational procedures for the SMAJAYU JY305 system.

5.1. PPP Operation Process

The Precise Point Positioning (PPP) mode allows for 10cm accuracy without a base station or subscription. Follow these steps to activate PPP mode:

1. From the main interface, click 'Status' then 'Self-Check'.
2. Click 'Parameter view' to enter the parameter viewing interface. Verify the board type (UM982) and firmware version (11826). Return after checking.
3. Click 'System' then 'Connect'.
4. Select 'External Data' and then 'PPP RTK' to enable PPP mode.
5. Return to the main interface and wait for the signal to change to PPP. This may take several minutes.
6. Once the signal is received successfully, PPP mode is active.

5.2. System Calibration

Accurate calibration is crucial for optimal performance. The JY305 system requires vehicle parameter measurement, gyro sensor calibration, and antenna roll value calibration.

5.2.1. Vehicle Parameter Measurement

Measure the following parameters on a flat ground and input them into the system:

1. Front wheel track.
2. Track width of front and back wheels.
3. Distance from antenna to ground.
4. Distance from antenna to front wheel.

5.2.2. Gyro Sensor Calibration

Calibrate the gyro sensor by turning the steering wheel left and right as prompted by the system.

5.2.3. Antenna Roll Value Calibration

Perform antenna roll value calibration to correct human error and ensure accurate navigation.

5.3. Setting AB Line for Straight Navigation

To set an AB line for straight navigation and allow the system to automatically correct errors:

1. Drive the tractor to point A and mark it on the system.
2. Drive the tractor to point B and mark it.
3. Start navigation, and the system will automatically correct the error to ±0-1cm.

5.4. Concentric Circle Navigation

The JY305 supports concentric circle navigation, ideal for working around a central pivot or irregular field shapes.

6. אַפּפּליקאַטיאָן סינעריאָוז
