Now it looks like your payload is correct
Try commenting out the icon and marker - see if that helps.

Otherwise, I have helped you all i can - I am unfamiliar with the worldmap node.
I have a doubt 
i think we have to pass only msg.payload in worldmap node.but we are passing other messages also thats why it is not showing on map.
Need help in removing other messages inorder to show on worldmap.so only message object must contain payload property.
So need to remove extra property fields in msg object for clear picture.
No. The worldmap will ignore those other message properties. You do not need to remove them.

You have to have the world map open and connected BEFORE you send it data. Apart from that you payload look fine.

Have you tried using a different name for the 2nd truck?
The documentation says...
name must be a unique identifier across the whole map. Repeated location updates to the same name move the marker
one of the trackers having device eui ending with 02 is facing issue in parsing through the buffer parser.Range issue don't understand why becoz both the trackers are in line of sight to the sky.
