GPS

For our first semester prototype, Alex selected the: Garmin GPS 18 5Hz ($200)

It gives us our GPS position every 200ms with an accuracy of at least 3.5m,
and with an expected accuracy of within a meter using WAAS.
It does not require a subscription to any service.

Gyro and Accelerometer

The gyro and acclerometer are a combo system created by SparkFun. It incorporates both the ADXL330 and IDG300 to enable measurements of acceleration along the x, y, and z axes and of angular rate about the x and y axes. For more information, please visit SparkFun's page on the IMU 5 Degrees of Freedom.
