Florida ? Former astronaut Lisa Nowak wants a judge to let her remove the ankle bracelet that allows authorities to track her as she awaits trial on suspicion of attacking a romantic rival, calling it expensive and unnecessary.

Nowak is paying $105 a week – $2,940 so far – for the monitoring device as a condition of her release, according to a court filing her attorney says was made Thursday. A clerk at the Circuit Court in Orange County could not find the filing, but said it could be on its way.

Nowak also argues that the device interferes with her ability to exercise and her ability to drive, fly on a commercial airplane and monitor her children in the pool.

Nowak has pleaded not guilty to attempted kidnapping, battery and burglary with assault. She is accused of attacking Air Force Capt. Colleen Shipman in a parking lot at Orlando International Airport.
