Arduino Uno GPS/GSM Shield

Here is the shield we found that already has a GPS reciever module and GSM transmitter with SIM card reader all set to go. The only modification we will most likely need to make is to extend the antennae for GSP and GSM so it is not blocked based on the orientation of the rocket payload compartment upon landing. The major drawback is the upon completion it will be 2 3/4 of an inch in diameter, so will not fit inside most standard Estes rockets.
