    Default Aluminum domes and gps signals



    Maybe a silly question.

    Do any of you with a metal dome use a gps inside your observatories? Do you pick up enough signal through the shutter, or none metalic walls to get a lock? Or do you use an external gps antenna located out side?

    Cheers,

    Len

    Hi,

    If you are using the GPS in your mount/HC for position and time/date, it is more of a nicety (almost gimmicky), certainly not a necessity. Once you've loaded your local data once it should always be there. To make sure your mount has the correct time, your cell phone can help with that. So no GPS is really necessary.

    Cheers,
    JT

    Yes, if you are under a dome, your location never changes. So GPS in that case is just an expensive clock. If you are having trouble getting a GPS signal, set up outside the dome one time. Let it get a GPS lock and set the location. The short distance from outside the door to the pier will make no difference to the coordinates. You can set the time from your watch or from a computer clock.
