niSync Get Velocity (VI)

Installed With: NI-Sync

Returns the last calculated velocity of the specified device's onboard GPS receiver.

You can display east velocity, north velocity, and up velocity in meters per second.

Note  
  • You must connect an external GPS antenna to your device to receive valid data from this VI, and you must enable Mobile Mode on the device to receive non-zero velocity values. You can enable Mobile Mode using Measurement & Automation Explorer (MAX) or by using the Mobile Mode property of the niSync Property Node.
  • This function is supported only on certain targets; refer to Target Support for Timing Properties and VIs for more information.
