Find below a listing of the total number of packets received by the
ZS7ANT station in Antarctica during the past three days, as well as
the number of packets for which each payload was below the horizon.
Total packets 23 + 19 + 55 = 97
PAYLOAD A 0 + 1 + 1 = 2
PAYLOAD B 3 + 9 + 46 = 58
PAYLOAD C 0 + 4 + 19 = 23
PAYLOAD D 2 + 10 + 17 = 29
PAYLOAD E 14 + 18 + 54 = 86
SL-24 R/B - RUBIN-2 23 + 19 + 55 = 97
The tle-new.txt keps from Celestrak were used (attached below).
This confirms Keith's observation that PAYLOAD A is the best fit to
SAFIR-M transmissions.
