ArgosId = 02794 Analysis period: From: Sat Jul 22 14:23:33 2000 To: Mon Jul 24 14:20:03 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 | 3 0 0 2 | 2 0 1 3 | 2 0 1 4 | 3 0 1 5 | 4 0 0 6 | 2 0 0 ----+-------------------- # | 16 0 3 Total messages received = 16 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 2 1 0 0 0 | 3 2 | 0 0 1 1 0 0 | 2 3 | 0 0 0 1 1 0 | 2 4 | 0 0 0 0 3 0 | 3 5 | 1 0 0 0 0 2 | 3 6 | 2 0 0 0 0 0 | 2 ---+-------------------+--- @ | 0 0 0 1 0 0 | 1 ---+-------------------+--- # | 3 2 2 3 4 2 | 16 Total messages received = 16 Total blasts received = 1 <<1>> 02794 | 3 2 2 3 4 2 | 16 1 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 $ ------------------------------------------------------------------------------------------------------------------ $ 00072409002819@argosinc.com 02794 4 4 ok 964362003 07 23 2000 14:20:03 51603 32 00072409002819@argosinc.com 02794 4 5 ok 964362045 07 23 2000 14:20:45 51645 32 42 00072409002819@argosinc.com 02794 4 6 ok 964362087 07 23 2000 14:21:27 51687 32 42 00072409002819@argosinc.com 02794 4 1 ok 964362129 07 23 2000 14:22:09 51729 32 42 00072409002819@argosinc.com 02794 4 2 ok 964362171 07 23 2000 14:22:51 51771 32 42 00072409002819@argosinc.com 02794 4 3 ok 964362213 07 23 2000 14:23:33 51813 32 42 00072409002819@argosinc.com 02794 4 5 ok 964362297 07 23 2000 14:24:57 51897 32 84 00072409002819@argosinc.com 02794 4 6 ok 964362339 07 23 2000 14:25:39 51939 32 42 00072409002819@argosinc.com 02794 4 1 ok 964362381 07 23 2000 14:26:21 51981 32 42 00072409002819@argosinc.com 02794 4 2 ok 964362422 07 23 2000 14:27:02 52022 32 41 00072409002819@argosinc.com 02794 4 4 ok 964362507 07 23 2000 14:28:27 52107 32 85 00072409002819@argosinc.com 02794 4 5 ok 964362549 07 23 2000 14:29:09 52149 32 42 00072409002819@argosinc.com 02794 4 1 ok 964362632 07 23 2000 14:30:32 52232 32 83 00072409002819@argosinc.com 02794 4 3 ok 964362716 07 23 2000 14:31:56 52316 32 84 00072409002819@argosinc.com 02794 4 4 ok 964362759 07 23 2000 14:32:39 52359 32 43 00072409002819@argosinc.com 02794 4 5 ok 964362801 07 23 2000 14:33:21 52401 32 42
