Do dishy's have IMUs (aka some means for determining attitude w.r.t. the local gravitational vector and true or magnetic north) or GPS modules (or both)??? I am somewhat skeptical that the system would be able to locate a UT just based on zero tilt transmissions from the UT. I am guessing something a bit more complex is transpiring, like some rudimentary form of SDMA (aka spatio-temporal resource allocation).

I've used it at a couple locations 5-10 miles away without a problem I asked starlink support about roaming and it's currently not supported, you can change the registered location, and if a slot is available, they'll approve it and guarantee service (view of the sky permitting). But when you do that you give up the slot at your home location and are not guaranteed to be able to move it back. They told me that I could try it, and it may work, may be degraded a bit, or may not work at all. They do plan to add roaming capabilities in the future (my guess is that the laser satellites will enable a lot more flexibility) David Lang On Mon, 21 Feb 2022, Mike Puchol wrote: > From what I have observed, there is a new "roaming" flag in terminal properties that determines roaming capability.

The backend then informs the terminal if it is out of its service address, and if so, it will just sit there doing nothing (although it does periodically send stuff). > > Best, > > Mike > On Feb 21, 2022, 23:31 +0300, Dick Roy , wrote: >> What does your contract say about the "where" you can expect service from >> your dishy?
