[acao-it] ACAO Tracking Protocol

[Ola Røer Thorsen]

Hi Danielle,

that PC should be quite sufficient! The 680-card is pretty powerful.

I'm currently watching live aerotows and glider operations from Varese
here, using the planes-by-day data. The quality of the tracking data is
quite good, for example the areotows look quite realistic in my end, and I
can watch the gliders try to find thermals on the nearby mountain top.

It seems like when using the "gettrackerdata" request, only the date part
of the start- and endtime parameters is considered on the server. This
means I get the same data repeatedly that I don't really need, and you'll
have to send me a lot more bytes.

For example, I normally start out by requesting all data for a given day,

&starttime=20150726000000&endtime=20150726235959

After receiving fixes up to let's say time 13:15:10, my next request will
be for 13:15:11 - 23:59:59

&starttime=20150726131511&endtime=20150726235959

(one second after time of last received position)

Can you please check if the timestamp is used correctly on the server  (the
Ruby-code I think)?

Is the tracker ID used the actual FLARM id, or something else? I'm thinking
about recognizing the trackers/aircraft so that we for example can use
towplane 3d-models for the towplanes.

Best regards,
Ola
