System Output

D2119 Dart RTLS User Guide 85

 <unit> except for P type data, is a Virtual Group ID (in decimal). The tag location data is

computed from the time of flight measurements of the Receivers within the virtual group. In

the case of P type data, <unit> is the Rx # of the Receiver that detected the transmission.

 <LF> is a Line Feed character (with ASCII code = 0x0A) to terminate a location data string.

The following is an example of system output from a Dart RTLS Hub.

Data Quality Indicator (DQI)

If you have enabled Data Quality Indicator (DQI) (see Configuring output control (on page 43)),

the output data appears in the following format, with an additional field <DQI>:

Where <DQI> is the Data Quality Indicator value for the location data. When the DQI result is

not meaningful this field contains an asterisk.

Geometric Dilution of Precision (GDOP)

Geometric Dilution of Precision (GDOP) is used to quantify the location accuracy of each blink

based on the geometry of the receivers detecting the tag blink and the calculated location of the

tag. If you have enabled Geometric Dilution of Precision (GDOP) (see Configuring output

control (on page 43)), the output data appears in the following format, with an additional field

<GDOP>:
