ArgosId = 02794 Analysis period: From: Mon Aug 7 14:21:40 2000 To: Wed Aug 9 14:13:58 2000 CRC State Map: The table below lists CRC statistics for the ensemble of ARGOS messages in the current profile. The column of indexes along the left margin represent ARGOS message id's. The `ok' column lists the number of times that each message was received and the passed the CRC check. The `bad' column lists the number of times that each message was received but failed the CRC check. The `missing' column lists the number of times that each message was skipped within one or more blasts. msg| ok bad missing ----+-------------------- 1 | 2 1 0 2 | 4 0 0 3 | 2 2 0 4 | 2 1 0 5 | 3 2 0 6 | 2 1 0 ----+-------------------- # | 15 7 0 Total messages received = 22 Receipt Matrix: The matrix below depicts the message receipt statistics for the current profile. The numbers along the left margin represent the row index `m' and the numbers along the top margin represent the column index `n'. Each element of the matrix gives the number of times that message-id `m' is followed by message-id `n' within a given satellite blast (regardless of the state of the CRC). The row indicated by a `@' indicates the number of times a that message-id `n' was the first in of a satellite blast. The row indicated by a `#' indicates the total number of times that message-id `n' was received (again regardless of the state of the CRC). Note: The total number of messages expected (N) is unknown to the utility that generated this matrix. Hence, if message N is completely absent from the data stream, no reference will be made to it in the matrix below. m n 1 2 3 4 5 6 | # ---+-------------------+--- 1 | 0 3 0 0 0 0 | 3 2 | 0 0 4 0 0 0 | 4 3 | 0 0 0 3 0 0 | 3 4 | 0 0 0 0 3 0 | 3 5 | 0 1 0 0 1 3 | 5 6 | 2 0 0 0 0 0 | 2 ---+-------------------+--- @ | 1 0 0 0 1 0 | 2 ---+-------------------+--- # | 3 4 4 3 5 3 | 22 Total messages received = 22 Total blasts received = 2 <<1>> 02794 | 3 4 4 3 5 3 | 22 2 The ideal set of transmissions would have zeros everywhere in the matrix except for the elements just above the diagonal and the (N,1) element (where N is the total number of messages in the profile). Any other non-zero elements indicate messages received out of sequence within some satellite blast. A null column indicates the complete absence of the respective message from the data stream and is flagged with a `*' in row `#'. The deviation of the matrix above from the ideal case is a good gauge of the overall quality of the transmissions for this profile. Argos Log Map: The table below details the receipt of each ARGOS message for the current profile. The column headers are described below. $ --------------------------------------------------------------------------------------------------------------- $ $ E-Mail-Msg-Id: Each email has a unique identifier. This field is that identifier $ and can be used to locate the ARGOS data within the large email archives. $ $ ArgosId: The platform identifier assigned to each ALACE float. $ $ Blast: All ARGOS data from a given satellite pass is clumped together under a single $ header within a given email message. This assemblage of data is referred to $ as a `blast'. $ $ MsgId: The message identifier. For a given blast (ie., satellite pass), the message $ identifiers should cycle in sequential order. $ $ CRC: The message CRC test results. $ $ TimeStamp: This field records the time when the satellite received the message measured as $ the number of seconds since Jan 1, 1970. $ $ mm, dd, yy: The date the satellite received the message. $ $ GMT: The time-of-day that the satellite received the message. $ $ DSec: This field records the time when the satellite received the message measured as $ the number of seconds since midnight of the day of receipt. $ $ B: The number of bytes in the received message (should be 32). $ $ dT: The number of seconds since receipt of the previous message within the same blast. $ $ ------------------------------------------------------------------------------------------------------------------ $ E-Mail-Msg-Id ArgosId Blast MsgId CRC TimeStamp mm dd yyyy GMT DSec B dT $ ------------------------------------------------------------------------------------------------------------------ $ 00080909002573@argosinc.com 02794 1 5 ok 965744038 08 08 2000 14:13:58 51238 32 00080909002573@argosinc.com 02794 1 6 ok 965744080 08 08 2000 14:14:40 51280 32 42 00080909002573@argosinc.com 02794 1 1 ok 965744122 08 08 2000 14:15:22 51322 32 42 00080909002573@argosinc.com 02794 1 2 ok 965744164 08 08 2000 14:16:04 51364 32 42 00080909002573@argosinc.com 02794 1 3 bad 965744206 08 08 2000 14:16:46 51406 32 42 00080909002573@argosinc.com 02794 1 4 bad 965744248 08 08 2000 14:17:28 51448 32 42 00080909002573@argosinc.com 02794 1 5 bad 965744290 08 08 2000 14:18:10 51490 32 42 00080909002573@argosinc.com 02794 1 6 bad 965744332 08 08 2000 14:18:52 51532 32 42 00080909002573@argosinc.com 02794 1 1 ok 965744374 08 08 2000 14:19:34 51574 32 42 00080909002573@argosinc.com 02794 1 2 ok 965744416 08 08 2000 14:20:16 51616 32 42 00080909002573@argosinc.com 02794 1 3 ok 965744458 08 08 2000 14:20:58 51658 32 42 00080909002573@argosinc.com 02794 1 4 ok 965744500 08 08 2000 14:21:40 51700 32 42 00080909002573@argosinc.com 02794 1 5 ok 965744542 08 08 2000 14:22:22 51742 32 42 00080909002573@argosinc.com 02794 1 5 bad 965744626 08 08 2000 14:23:46 51826 32 84 00080909002573@argosinc.com 02794 1 2 ok 965744668 08 08 2000 14:24:28 51868 32 42 00080909002573@argosinc.com 02794 1 3 ok 965744710 08 08 2000 14:25:10 51910 32 42 00080909002573@argosinc.com 02794 1 4 ok 965744752 08 08 2000 14:25:52 51952 32 42 00080909002573@argosinc.com 02794 1 5 ok 965744794 08 08 2000 14:26:34 51994 32 42 00080909002573@argosinc.com 02794 1 6 ok 965744836 08 08 2000 14:27:16 52036 32 42 $ 00080909002573@argosinc.com 02794 2 1 bad 965759494 08 08 2000 18:31:34 66694 32 00080909002573@argosinc.com 02794 2 2 ok 965759536 08 08 2000 18:32:16 66736 32 42 00080909002573@argosinc.com 02794 2 3 bad 965759578 08 08 2000 18:32:58 66778 32 42
