Object Tracking Classifiers and Flags

OVERVIEW

Objects such as people (via phone apps), assets, network servers, aircraft, ships and other vehicles all can be tracked using Limelight XE™.  To allow mapping systems to classify an object, a classifier ID is used.  In addition, object status is provided so mapping systems can indicate a status if required.  See the tables below for all values used for object classification and status.

Special Air Vehicle Modifiers

The following table shows the value of the lower 5 bits of the air vehicle classifiers (per GDL90 extended protocol 1).  This adds more resolution to the classification based on data received from ADS-B receivers. These values are OR'ed with the above air vehicle classifiers. For example, a classification code of 0x41000005 is a heavy multi-engine aircraft like a Boeing 747.

Special Animalia Modifiers

The following table shows the value of the lower 2 bits of the animalia classifiers.  This add the sex of the organism (if applicable) if required (e.g. tracking livestock).

Value Bits (0-1) Description
0x00000000 00 Sex Unknown / Not Required
0x00000001 01 Male
0x00000002 10 Female
0x00000003 11 Asexual (just in case...)

TRACKING OBJECT FLAGS

The table below shows the values of various flag bits returned in tracked object records.  The returned value can be any of the values below logically OR'ed.  For Example a value of 0x40000003 indicates the object is in alarm and the position and rates are valid between the last access and the radio contact.

Value Bit Description
0x00000001 1 Position value (e.g., lat, long) is available
0x00000002 2 Altitude value is available
0x00000004 3 Altitude rate value is available
0x00000008 4 Heading value is available
0x00000010 5 Heading Course Over Ground (COG) value is available
0x00000020 6 Heading rate value is available
0x00000040 7 Speed value is available
0x00000080 8 Speed overflow
  9-13 (Reserved)
0x00002000 14 Object is inside of a geofence area
0x00004000 15 Object is excluded from geofencing
0x00004000 15 Object is excluded from geofencing
  16-18 (Reserved)
0x00040000 19 Object is off position (e.g., a fixed ATON has broken from its anchor)
0x00080000 20 Object position accuracy is degraded
0x00100000 21 Do not store object (e.g., the information is stored elsewhere)
0x00200000 22 Virtual target (Object is synthetic and doesn't physically exist)
0x00400000 23 Object is in alarm
0x00800000 24 Object is locked from automatic updates (e.g., sensor inputs cannot update the static data)
  25-32 (Reserved or used internally)
