ORBIT-USER: Global Positioning Service in ORBIT

[Arinto Murdopo]

If the position service is provided using a configuration file, will there
any synchronization problem between the nodes? My thought is maybe the node
will read incorrect position because the destinatino node doesn't read the
configuration file in the same time. Is this problem possible to happen?

By the way, sorry I don't get what you mean. What does "tow implementation"
mean? Could you give me more example?

Thank you

Arinto
