ArgosId = 02794 Analysis period: From: Sun Jul 30 14:29:23 2000 To: Tue Aug 1 14:17:29 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 | 1 1 1 3 | 2 1 0 4 | * 1 2 5 | 2 1 0 6 | 3 0 0 ----+-------------------- # | 10 5 3 Total messages received = 15 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 0 0 0 | 1 3 | 0 0 0 1 2 0 | 3 4 | 0 0 0 0 1 0 | 1 5 | 0 0 0 0 0 3 | 3 6 | 3 0 0 0 0 0 | 3 ---+-------------------+--- @ | 0 0 1 0 0 0 | 1 ---+-------------------+--- # | 3 2 3 1 3 3 | 15 Total messages received = 15 Total blasts received = 1 <<1>> 02794 | 3 2 3 1 3 3 | 15 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 $ ------------------------------------------------------------------------------------------------------------------ $ 00080109003249@argosinc.com 02794 1 3 ok 965053049 07 31 2000 14:17:29 51449 32 00080109003249@argosinc.com 02794 1 5 ok 965053133 07 31 2000 14:18:53 51533 32 84 00080109003249@argosinc.com 02794 1 6 ok 965053175 07 31 2000 14:19:35 51575 32 42 00080109003249@argosinc.com 02794 1 1 bad 965053217 07 31 2000 14:20:17 51617 32 42 00080109003249@argosinc.com 02794 1 3 ok 965053301 07 31 2000 14:21:41 51701 32 84 00080109003249@argosinc.com 02794 1 4 bad 965053343 07 31 2000 14:22:23 51743 32 42 00080109003249@argosinc.com 02794 1 5 ok 965053385 07 31 2000 14:23:05 51785 32 42 00080109003249@argosinc.com 02794 1 6 ok 965053427 07 31 2000 14:23:47 51827 32 42 00080109003249@argosinc.com 02794 1 1 ok 965053469 07 31 2000 14:24:29 51869 32 42 00080109003249@argosinc.com 02794 1 2 bad 965053511 07 31 2000 14:25:11 51911 32 42 00080109003249@argosinc.com 02794 1 3 bad 965053553 07 31 2000 14:25:53 51953 32 42 00080109003249@argosinc.com 02794 1 5 bad 965053637 07 31 2000 14:27:17 52037 32 84 00080109003249@argosinc.com 02794 1 6 ok 965053679 07 31 2000 14:27:59 52079 32 42 00080109003249@argosinc.com 02794 1 1 ok 965053721 07 31 2000 14:28:41 52121 32 42 00080109003249@argosinc.com 02794 1 2 ok 965053763 07 31 2000 14:29:23 52163 32 42
