1. A system for determining a hitch angle between a vehicle and a trailer, comprising: a first GPS receiver disposed on-board the vehicle;a portable electronic device having a second GPS receiver and disposed on-board the trailer; anda controller for determining a hitch angle based on data received from the first and second GPS receivers and comprising a hitch angle detection module configured to alternate between receiving data from the first and second GPS receivers. 2. The system of claim 1, wherein the portable electronic device is coupled to a rear structure of the trailer and is disposed to capture image data rearward of the trailer. 3. The system of claim 1, wherein the portable electronic device comprises one of a smart phone and a tablet. 4. The system of claim 1, wherein the first GPS receiver is operable to determine a vehicle position and the second GPS receiver is operable to determine a trailer position. 5. The system of claim 4, wherein the controller calculates the hitch angle by comparing the vehicle position to the trailer position. 6. The system of claim 1, wherein the hitch angle detection module comprises a Kalman filter for extrapolating a vehicle position and a trailer position from the data and subsequently computing the hitch angle based on the extrapolated vehicle position and the extrapolated trailer position.
