Note: If you have not registered with SNIP, it is only online for 1 hour, and you can experience all functions within an hour and manage 5 CORS stations at the same time. After an hour you can restart SNIP to get back online. If you register SNIP for free, you can permanently use the basic functions and keep 3 CORS stations online for a long time.
