Data Question on VRD165 on 042015 KJFK - KLAX

What would cause such a data anamoly from this feeder site? Could simply moving the antenna during a position recording give this erroneous reading on 042015_VRD165 KJFK - LAX?

Any ideas? Thx

It is usually time synchronization not being perfect on that feeder. Moving the antenna doesn’t alter the positional values reported since they are measured and transmitted literally from the aircraft.

Thanks. Is that something that can be corrected at the receiver or is this more of just a one time data hiccup?
