Vlink Dlink del sistema automático de seguimiento de antena

At the user manual of Automatic Antenna Track system, https://ivcan.com/wp-content/uploads/AAT-User-Manual.pdf, en la página 11, it mentioned Vlink and Dlink.

Display Item	Descripción
GPS/Local GPS	GPS Satellites locked. If an external GPS is connected, GPS/LocalGPS will be displayed in 12/11 formation (GPS=12, Local=11)
Batt	Batt (Voltage of the main battery) will be displayed alternatively here.
Dist	Distance of the plane (Not Available before SetHome)
alt	Altitude of the plane (Not Available before SetHome)
Azim	Azimuth of the plane (Not Available before SetHome)
VLink/DLink	Video/Data downlink quality. (en %, ref to the “Enlace descendente” chapter)
Dir/EDir	Current heading diretion of the tracker. If an external compass is connected, EDir will be displayed alternatively

Crossbow AAT needs both these 2 Mensajes MAVLink para rastrear.
MAVLINK_MSG_ID_GPS_RAW_INT
MAVLINK_MSG_ID_GLOBAL_POSITION_INT
If the Crossbow AAT receives some correct MAVLink data packs (Latido del corazón?) but not able to find
the above 2 mensajes, se mostrará “Dlink:1% mensaje?” para recordarle que compruebe si lo anterior 2
Los mensajes se envían a 1 Hz o una frecuencia superior..

Q1: Why does the menu sometimes show Vlink and sometimes Dlink?

A1: The default display is Vlink, If the data is correct, Dlink will be displayed. Pleae check whether the factory-coredata-rx parameters are increasing. Please take a look at the received data from the Rx.

If the data fails to show an increase, then you should try to change and test the TX and RX cables against one another to identify the problem.

Q2: The functionality of the Yaw feature on the Menu of the AAT Automatic Antenna Track system, what could be causing it to not move?

A2: This Yaw menu’s functionality and validation are contingent upon the tracking process; it is only effective and validated while tracking is active.

This parameter means, how many degrees offset based the original tracking direction

Q3: I am curious about why the flight control system failed to transmit the necessary real-time operational data to the AAT.

A3: Are the baud rates that you have configured identical for both the data link and the AAT system? Please check it, default setting of AAT is 57600.

We kindly request that you send us a picture or video of your connection diagram; our engineer will then be able to analyze it, identify the potential issue, and provide you with a suitable solution.
