PocketSat and PocketSat+ Data Sources
[At the moment, PocketSat+ for PalmOS uses normal PocketSat import databases, and so this is still the place for data and tools. This may change in the future, but I'll be sure to let you know.]
[And another thing: Check out the new BigFatTail support forums for more info about PocketSat and PocketSat+.]
Satellite orbits are always changing, so it is necessary to periodically update your PocketSat data. Actually I'm not all that sure how the predictions degrade with time, but I find that I have generally have no problem using month-old data for naked-eye observation.
Ready-to-use PalmOS Data
For your (and my) convenience, I have set up a perl script that periodically fetches TLE ephemeris data from a couple of my favorite satellite observation web sites and converts it into PocketSat for PalmOS input databases. These can then be downloaded using your web browser and loaded right into PocketSat:
Pocket PC Data
Since you can copy a normal text file onto a Pocket PC, PocketSat+ for Pocket PC doesn't have a special import format. In the interest of being "parallel", however, here are links to the TLE files used to create the PalmOS databases listed above. Download them by right clicking and choosing "Save Target As" (or however you do it using your particular browser):
Other TLE Data Sources
There are several places where you can find up-to-date TLE data files for a wide variety of satellites and types of satellites. Here are a few of them:
Andreas Schneider has written a really cool utility that allows people with Palm Pilots that can connect to the Internet to import text TLE files directly into PocketSat. It's free, too. Get it at his web site.
Once you've downloaded a TLE data file, you need to get it into your Palm Pilot. One way to do this is to create a memo containing the data (remember that it must start with a title line), HotSync it to your Pilot, and use PocketSat's "Import from Memo" feature. Unfortunately, memos are limited to 4K of text, which is only enough for 15 satellites or so. For larger amounts of data, you will want to create a PocketSat Input Database and HotSync it to your Pilot just as you would any .PDB or .PRC file.
Here are some tools to convert TLE files into input databases:
