Re: RAFT is coming down! Grab telemetry
Hi Bob, I'm at work but my antenna is beaming at the average max elevation points of all today's passes (basically South) and should be sending in the TLM via ZL2BAU. David, ZL3AI may also be monitoring/gating. 73 Geoff ZL3GA Christchurch, New Zealand RE66ho

RAFT is de-orbiting within the next 12 hours or so.
It will arrive much earlier than any prediction based on Keplarian Elements because they are always too old. Best bet is to start 20 minutes early and point your beam towards AOS and where it will get about 10 deg above the horizon and wait. Then manually follow the
short 3 minutes along the track... >
- Who will get the last telemetry?
- How hot will it get before telemetry dies?
We need worldwide operators collecting telemetry packets if they want to capture the last packet.
See the live temperature plot on the RAFT-RE_ENTRY WEB PAGE...

We particularly need data from the southern hemisphere where the passes are in the sun and will show the
highest temps... >
Tune in 145.825 1200 baud AX.25 packet. And even with a small antenna, on the two overhead passes per day, you should get at least one telemetry packet. They are every 10 seconds.. Each one begins with a unique serial T#nnn and so we can merge different captures from
different folks. >

Could this be the best recorded AMSAT re-entry ever?
