I have a GPS tracker service that i have done years ago in vb.net.
It is working at this momment, but now i have more than 60 units connected to them and the tracker is not run correctly because it "crash" after it is running several days.
The app work with MS SQL server.
Due to this i need you redone it. We work with laipac and arknav GPS units (i have documentation for them) but may be on future we work with other companies so is neccesary that the protocols can be increased easily (added a new class)
Please let me know if you have done this type of soft and the the language you want use to do the project and why.
I will supply the current source code to the hired.
