Hi Doug,

When you download the track from the DC20, you do get altitude. Not only that, but the track can then be uploaded to Google Earth, so you can see the whole track complete with altitude. Pretty cool.

Amen Brother. 😉

Hey Ken,
Can you give us a simple tutorial on the DC data upload to google earth? I haven't done that before. I knew about the altitude and have heard about the upload, but.....

On a side note - Doug, there are a lot of guys in the club using them. I would bet someone would let you try it out.

It's pretty simple, really. First, you will want to plug your USB cable into your Astro. Then start Google Earth. in Google Earth, drop down the Tools menu and select GPS. You will get a dialog, make sure it looks like this:

Then click the import button. It will procede to download all the tracks from the Astro and put them in a Temporary Places folder.

If you just want to see what one of these tracks looks like, you can download this file and then open it in Google Earth (Right-Click the word file and select Save Target As).

Older versions of Google Earth required an upgrade to Google Earth Plus for the GPS import to be able to do altitude, but this feature is now part of the standard program, so you may need an upgrade.

Thanks for the info, you guys are great. Have any of you had the RF interference problems that Mike Konshak spoke of in his Sport Rocketry article. It seems to me that this may be a reason to go with a accel based altimeter. Have you found the 2 ft distance rule to be sufficient or is everyone RF shielding the alts?

Thanks again

Two feet?
Is that what is was suppose to be?
I just figured as long as it was in a different bay, at the top moastly.

All though, I have a Dart with very little room, that would all have to be in the same bay.

Glad you brought it back up! Hmmmmm...

Any body know if RF signals will mess with timers?
I built a first stage booster with the tracker in the same bay as the timers.
