Abstract

A method of analyzing data link messages is disclosed. These messages include a message type field and at least one message content field whose meaning is determined by the message type. The method includes storing the plurality of data link messages in a database. The method also includes assigning each data link message to one or more message groups according to the message type field so that each group contains data link messages of a specific message type. In addition, the method includes tabulating the messages so as to align corresponding message content fields, displaying the tabulated messages so that the corresponding message content fields are aligned; and displaying a list of the field contents for each message content field. The displayed list is filtered to remove repeated incidence of the same content, within each of the message groups.

Claims

1. A method of analysing data link messages,

the method comprising the steps of:

(a) receiving a plurality of data link messages, each of the data link messages being formatted digital data sequences transmitted between units, and include a message type field and at least one message content field whose meaning is determined by the message type;

(b) storing the plurality of data link messages in a database;

(c) assigning each data link message to one of a plurality of message groups according to the message type field so that each group contains data link messages of a specific message type;

(d) within each of the message groups,

(i) tabulating the messages so as to align corresponding message content fields;

(ii) displaying the tabulated messages so that the corresponding message content fields are aligned;

(iii) filtering selected message content fields to remove repeated incidences of the same content; and

(iv) displaying a list of the field contents for each message content field.

2. A method according to claim 1 wherein each group contains all data link messages of a specific message type.

3. A method according to claim 1 wherein the list is sorted in a desired order.

4. A method according to claim 1 wherein the group is filtered so as to display only messages having a particular content for that field type, the content having been selected from the list.

5. A method according to claim 1 wherein the list is filtered to remove repeated incidence of content falling with a specified range.

6. A method according to claim 1 in which the data link messages are tactical data link messages.

7. A method according to claim 1 in which the messages are tactical data link messages originating from a plurality of military platforms, the messages being in digital form, at least some of which being transmitted by the units via a wireless network.
