No, we have designed this to "plug and play" with your existing GS2. You don't need extra's if you are not wanting it, but we can demo "extra's" to you via Virtual Wrench capability.

Example: Say you want Glonass with your mojoRTK that is connected to your GS2. We can send that to you via Virtual Wrench for you to "demo" to see if it is an upgrade that you want for additional satellite coverage. That is the beauty of Virtual Wrench beyond its immediate service capabilities. You get to try additional upgrades that might fit your needs.

Thanks,

Trevor
