The problem is that I am not sure what this will\ntell you other than that A-07 switches off as it enters eclipse. This is a\nlow pass here (10 deg max el.) and according to me it will go into eclipse\njust after my TCA. If you are looking for the exact time of eclipse I would\nhave to put a signal through the transponder and note the time I loose my\nsignal but I suspect on a low pass this may not be very accurate.\n\n73\nAlan\nZL2bx\n\n-----Original Message-----\nFrom: [email protected] [mailto:[email protected]] On\nBehalf Of K4FEG\nSent: Monday, 20 May 2013 18:00\nTo: [email protected]\nSubject: [amsat-bb] AO7 Eclipse Period\n\nAre there any of the New Zealand satellite operators that could listen \nto /*AO7 on May 21, 2013 during the 13:45:50UTC pass?*/\n\nIf I am correct this will be the beginning of the satellite eclipse \nperiod that will run until August 2, 2013.\n\nI am not using any fancy software to track the eclipse periods so I \ncannot determine if the times are accurate or not, nor if the satellite \ntracking software is taking full account of all variables involved in \ntracking an eclipse period on AO7.\n\nMy understanding from others is that the design of the satellite is such \nthat it will come up as the \"first state on start-up\" in Mode B. I do \nnot know these things to be true but the information comes from what I \nconsider to be reliable sources.\n\nI am just interested in any type of satellite report from the operators \nthat will first access to AO7 after it has been in an eclipse period no \nmatter how brief. Any information will be of interest to me.\n\n/The current mode switches on AO7 are occurring at approximately 1047UTC \neveryday, I suspect that if we get any type of a total voltage loss on \nthe satellite that this time will change(just my opinion)./\n\n From the projections I have been running the eclipse periods will \nquickly increase in duration and they will vary during the day with \nrespect to the time of day over the Southern Hemisphere.\n\nOne of my goals is to try and determine, with the software available to \nme, what duration of eclipse is needed to cause a \"Zero Voltage Reset\", \nwhich should result in the satellite reverting to Mode B.\n\nAny help is appreciated! Happy \"Bird\" watching!\n73\nFrank\nK4FEG\nEM55aj84ta\n_______________________________________________\nSent via [email protected].
