In China,The Land Survey  company don't pay full price for these equipment.

As most of the time,the 
Land Survey company use this RTK for only 1 or 2 years in project.After that,they will upgarde to new equipment.
So the dealer of CHC,will only give 1 or 2 years 
Activation Code to Land Survey company.

Then the
