Get Velocity

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 function, 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 parameter of niSync Properties.

Standard Error Behavior

datatype_icon

east velocity

The current east velocity, in meters per second, of the device.

Negative values represent how fast the device is traveling west. Positive values represent how fast the device is traveling east.

datatype_icon

north velocity

The current north velocity, in meters per second, of the device.

Negative values represent how fast the device is traveling south. Positive values represent how fast the device is traveling north.

datatype_icon

up velocity

The current up velocity, in meters per second, of the device.

Negative values represent how fast the device is traveling down. Positive values represent how fast the device is traveling up.
