Note
Some menu items listed above may not appear in your application, or not appliable in your application, it depends on your license type.

Tool Bar

There are serveral tool bars.

Main toolbar contains commonly used function tool buttons, the function is exactlly the same with corresponding menu item.

Filter toolbar is uesed for filter function.

Status Bar

Status bar is at the bottom of main window, it shows status information and application message.

Main View

In the middle of main window, it is the main view. There are different types of view, Tree View and Track View.

Tree View

Tree view is the default view after ASTERIX Analyzer starts up. In this view, ASTERIX data is shown in a tree style hierarchy.

ui_treeview.png
Tree View

The tree view composes of four parts:

  • Data packet list
  • Data block/record/item tree
  • Raw hex data
  • Data record/item detail

Packet List

Packet list is on left of tree view, loaded data packets are shown in this list. A sequence number, timestamp and size is displayed for each data packet.

The timestamp here is the receiving UTC time, if data is loaded from file, it means the time when packet is saved into the file.

Note
For some file formats, timestamp is not avaliable, the timestamp field will be displayed as "N/A".
For some file formats, timestamp has only valid time, and no valid date, the timestamp field will be displayed with only time.

When one packet is selected, its content will be displayed in the Raw Data Display panel.

When one packet is selected, system will try to decode it with selected frame and UAP. If it can be successfully decoded, the structure of this data packet will be display in the ASTERIX Tree panel.

ASTERIX Tree

ASTERIX tree is in the middle of tree view, it shows standard ASTERIX data struct in a tree style hierarchy, which are:

  • Data Block
  • Data Record
  • Data Item

The concept of these terms are defined in Eurocontrol ASTERIX documents.

The encoding policy supported by ASTERIX Analyzer is:

  • One data packet can include one or more data blocks
  • One data block can include up to 32 data records
  • One data record can include up to 32 data items

When one data block or data record or data item is selected, the corresponding data will be highlighted in Raw Data Display panel.

When one data record or data item is selected, the decoded ASTERIX fields will be displayed in detail in Detail Display panel.

Raw Data Display

Raw data display is on top-right of tree view. Data of data packet will be shown in hexadecimal format in it. If one data block/record/item is selected, the corresponding data will highlighted.

Detail Display

Detail display panel is on bottom-right of tree view. It is a standard web browser, when a data record/item is selected, a HTML page will be generated and displayed in detail display panel.

The content in this panel depends on the selected data.

Track View

Track view is used to display important properties of aircraft in a table.

Track View

The columns in this table are:

Column Description Note
Country Country of the aircraft, according to its ICAO address If some ICAO address can't be recognized, airdb should be updated
SAC/SIC SAC/SIC of sensor This is useful when data comes from multiple sensors
Time Stamp Time stamp of data transmission
Type Plot, Track & ADS-B
Track Number Track number Valid only when type is "Track"
Mode 3/A Mode 3/A code, suffix 'S' means "smoothed", 'G' means "garbled"
Flight Level Mode C code
Callsign Mode-S callsign
ICAO Address ICAO 24-bit address of aircraft
Polar Coordinates Range and azimuth Valid only for radar
WGS84 Coordinates Latitude and longitude Valid for ADS-B, Mlat and system track
Speed Ground speed
Heading Heading

When system reads one qualified data record, it will extract properties included in the data record, and generate a row. If any property is not appliable to the data record, the corresponding ccolumn will be displayed as blank.
