It’s not exactly LEO orbit, but you can track the annual running of the A/N game football from Annapolis to Phily starting at noon.
USNA-1 will always be with the ball while -2,-3,-4 will be shuttling runners.
The 8W Byonics MicrotrackTT4’s are set to use Proportional-Pathing so that close in, (simplex/direct) they are updated at a known 1 minute rate making rendezvous practical, while the first digi hop is only once every 2 minutes. And then there is only a regional 2 hop packet once every 4 minutes. This keeps the 144.39 MHz channel loading down an order of magnitude while still providing close in 1 minute special event tracking quality.
And, knowing the rate is always one minute direct, 2 minutes via one digi and 4 minutes regional, makes it easy to know when packets are missing and how best to anticipate the nice DeadReckoning header as displayed on APRS.FI .
