1993 W1AW ARRL Keplerian Bulletins Description File
New ARRL Keplerian Bulletins are transmitted by W1AW twice weekly, on
Saturdays and Tuesdays at 6:30p.m. Eastern time (immediately following the
regularly scheduled RTTY bulletin). The transmissions are 3 mode RTTY,
starting with Baudot, followed by Amtor, followed by ASCII (as time allows).
The Keplerian bulletins contain Amateur satellite orbital data in two-line
NASA format, which can be decoded with the following key:
1 AAAAAU 00 0 0 BBBBB.BBBBBBBB .CCCCCCCC 00000-0 00000-0 0 DDDZ
2 AAAAA EEE.EEEE FFF.FFFF GGGGGGG HHH.HHHH III.IIII JJ.JJJJJJJJKKKKKZ
KEY: A-CATALOGNUM B-EPOCHTIME C-DECAY D-ELSETNUM E-INCLINATION F-RAAN
G-ECCENTRICITY H-ARGPERIGEE I-MNANOM J-MNMOTION K-ORBITNUM Z-CHECKSUM
Because of the similar subject matter in each bulletin, there are no
individual bulletin descriptions available.
The staff of W1AW would like to thank NASA, AMSAT and N3FKV for supplying
Keplerian data for W1AW bulletins.
