text clarification in Section 1.2.2 #10

Closed mglt closed 3 years ago

mglt commented 3 years ago

1.2.2. Network RID """ at either end with the Internet between. For all, but the simplest hobby aircraft, telemetry (at least position and heading) flows from the UA to the GCS via some path, typically the reverse of the C2 path. Thus, RID information pertaining to both the GCS and the UA can be sent, by whichever has Internet connectivity, to the Net-RID SP, typically the USS managing the UAS operation. """

I am reading the text as mentioning that the simplest hobby aircraft are excluded from the discussion. I think the reason is that they do not have telemetry flows. If that is the case, I suggest that one either mention the two categories of aircraft explicitly, or remove the distinction. More specifically - assuming my interpretation is correct - it seems evident that the text precludes the existence of such flow, while the current text - at least my reading of it - let suppose there might be another (simpler) path.

@mglt I actually agree there is no need to be very specific about what hobby aircraft may/not be in the picture.

i propose to remove the "For all, but the simplest hobby aircraft"

mglt commented 3 years ago

I agree.

It should not be assumed that all UAS have a flow of telemetry from the UA to the GCS. Some simple hobby aircraft don't. If the link is not there to support telemetry, it cannot be re-used to support Network RID.

For all but the simplest hobby aircraft, telemetry (at least position and heading) flows from the UA to the GCS via some path, typically the reverse of the C2 path. Thus, RID information pertaining to both the GCS and the UA can be sent, by whichever has Internet connectivity, to the Net-RID SP, typically the USS managing the UAS operation.

> Editor-note 3: Does all UAS support telemetry? explain what are simplsest hobby aircraft vs UAS in general. Is it necessay to keep "For all but the simplest hobby aircraft"?

mglt commented 3 years ago

i propose to remove the "For all, but the simplest hobby aircraft". If not it should be clearly justified so the reader understands why we are making such distinction.

implemented as following:

Telemetry (at least UA's position and heading) flows from the UA to the GCS via some path, typically the reverse of the C2 path. Thus, RID information pertaining to both the GCS and the UA can be sent, by whichever has Internet connectivity, to the Net-RID SP, typically the USS managing the UAS operation.
