Digipeating via ISS - tutorial

Hello ISS Fans:

I wrote a presentation / tutorial on ISS APRS digipeating which might be of general interest. You can find my 40+ page PDF presentation at:


Any and all comments are most welcome. Thanks.

Dear Peter,
your presentation is great stuff, very compact and instructive!
Being a long time ham, but unexperienced in Satellite operations it helped me to get a
sense of achievment via ISS after some minutes reading only.

Thank you very much.

Packet - just one aspect of satellite communications

Your welcome Christian,
My presentation just covers one small aspect of satellite communications, as it relates to packet. I have no experience with other means, such as voice. I just know enough packet and APRS stuff to be dangerous - but I thought I'd document a cookbook method of doing at least something via satellite (the Space Station no less), to make packet somewhat exciting. And it requires no active involvement of the astronauts/cosmonauts orbiting in space! So it gives hams an opportunity of achieving successful communications without live participants.

Quick review

Info on page 6 about passes does not take into account people near equatorial latitudes where 1 pass every 12 hours is more the norm nor does it thake into account operators near the 50 degree latitude where up to 7 passes in a row are possible.

On page 7, you indicate 2 amateur radio stations and then what appears to be callsigns. Currently, only 1 of the 3 tranceivers is operational. Callsigns in use by ISS amateur radio operations include (but are not limited to) RS0ISS, NA1SS, DP0ISS and OR4ISS. "ARISS" is the universal alias for digipeater operations.

On page 17, If you indicate use of RS0ISS-4 and operations change to one of the other supported modes (RS0ISS-3 for instance) then digipeat funtions will not work. It is best to just indicate the "ARISS" alias that works in all modes.

Can you reduce the image sizes so the document is smaller?

Thanks for the great tutorial

Thanks for the great tutorial on digipeating via ISS. It is a very helpful presentation.

I do have one suggestion: you might consider adding a page showing the settings for the Kenwood THD7 and D700.

Settings for Kenwood THD7 and/or D700?

Can anyone provide any Kenwood THD7/D700 setting information
that I can use in my presentation, per KE7DMs request? I personally
have no experience with these transceivers. Thanks in advance.

Glad to know that the presentation is of some usefulness.
