Question about the sharing feature. I'm on an ADSL service with

restricted limits per month. So my questions are about the sharing


How often does PP upload SBS-1 data to the central server?

How often does PP download aircraft data from the central server?

Is there anyway of setting PP up to share my SBS-1 data whilst at the

same time NOT downloading aircraft data? In that way I could share my

SBS-1 data at times when I'm not interested in viewing other's data.

If in doubt, consult the help file ;-)

It speaketh thus:



Use this option to toggle sharing of your position message data with other

users. When enabled, all your current position data will be uploaded to a

server once per minute.

Dick has commented on the uploads.

For downloads, the program (if it is the same as Ship Plotter) downloads

for the current (maximised?) screen area plus a 50% margin on each side.

So if nothing would be on the (extended) screen, the download bandwidth

consumption would be minimal. The download figure I quoted earlier is for

a visible region of the northern UK from about 53.5 N to 57N. It would

likely be higher for southern England.

Thanks Bev, I guess I should have checked the help file (now that

I've got help working in Vista)

So, I've zoomed right in close to cover an area of only a couple of

miles across, without any aircraft within 30 miles, but still it

downloads 70 aircraft. Is there some sort of minimum number of

aircraft that PP always downloads?

I'm trying to setup PP to always upload aircraft from my SBS1, but

not download any aircraft (for those times when I'm not at my PC).

I've now done my own testing (using PRTG and SNMP data from my router),

and with a download of approx. 210 aircraft each 60 seconds, this

consumes approx. 450mb per month.

On average my uploads/downloads are 5/70 (covering all of Scotland and

most of north England), so I'm probably only using 150MB per month,

which is not an excessive chunk out of my 8GB allowance.
