Ublox Data Accuracy
Provides the GPS data fields associated with data accuracy.
| This block is currently a beta version because it does not work with all Ublox GPS devices. If you are using this block, we would appreciate any feedback at tech@quanser.com. |

Description
The Ublox Data Accuracy block provides the values of Horizontal Dilution of Precision (HDOP), Vertical Dilution of Precision (VDOP), Position Dilution of Precision (PDOP), Position Fix flag, the number of satellites used in the solution, and the number of satellites in view obtained from GPS data structure.
Input Ports
gps_data
A handle containing Ublox GPS data structure.
Output Ports
hdop
Value of Horizontal Dilution of Precision (HDOP).
vdop
Value of Vertical Dilution of Precision (VDOP).
pdop
Value of Position Dilution of Precision (PDOP).
pos_fix
Value of the position fix flag.
sat_in_fix
Number of satellites used in the solution.
sat_in_view
Number of satellites in view.
err
The error signal returns a negative value in case of invalid GPS data obtained from a Ublox unit.
Parameters and Dialog Box
Sample time
The sample time of the block. A sample time of 0 indicates that the block will be treated as a continuous time block. A positive sample time indicates that the block is a discrete time block with the given sample time.
A sample time of -1 indicates that the block inherits its sample time. Since this is a source block, only inherent the sample time when it is placed in a conditionally executed subsystem, like a Triggered or Enabled Subsystem, or in a referenced model.
To use the fundamental sampling time of the model, set the sample time to qc_get_step_size, which is a QUARC function that returns the fundamental sampling time of the model.
