<p dir="ltr">Hi,</p>
<p dir="ltr">I know there are many versions of WGS84. I have a pro GPS with post processing and I can select various versions for my needs.</p>
<p dir="ltr">My question is for hand held non commercial GPS devices or for small drones or tools that don't use DGPS. (I know that most receivers have an error that is bigger than the added precision of the various ,WGS84 versions). </p>
<p dir="ltr">When WGS84 is updated, is it just an update to the reference frame on the ground or is the info downloaded from the satellite also updated or are they still broadcasting in WGS84(original)? If it's just a reference frame update, then we need to shift the data if we want it in the new wgs84(G1674). If the satellites are updated, then the information is already in WGS84(G1674)...</p>
