title: Is it possible to develop Indoor navigation by using ARCore?
body: <p>I tried to achieve using google's cloud Anchors, but it has a limitation of 24hrs (after that the cloud anchors become invalid).<br>
  And another way is creating the replica of Unity, but that would be too lengthy process.</p>
  
  <p>Any other ways please suggest me or any idea: <a href="https://www.insidernavigation.com/#solution" rel="nofollow noreferrer">https://www.insidernavigation.com/#solution</a> - how they achieved it?  </p>
  
  <p>And how to save the common coordinate system in cloud or locally? </p>
