Project Description:
We need a basic iPhone app to use as an experimental test bed for the native GPS/Gyro/Magnetometer outputs for iPhone running iOS6. This app will NOT be deployed to the public, but instead will only be used by a few of our developers for hardware experimentation and data collection. So, the UI does not have to be well developed or polished, just have some basic functionality.

The app will need to:
1) Record up to 10 GPS fixed calibration coordinates.
To record calibration point GPS data, a user would move to one of the fixed positions, push a button and run a 5-10 second process to determine the GPS position of that point. This will be repeated for up to 10 points. The contents of the file will include each individual measurement during the 10 second period and fields will include, calibration point number, Local time, GPS system time (utc), elapsed time, lat, long, and all other GPS fields available within iOS 6, such as satellite count etc. The data for each one of these individual test periods will be saved and exported as a file to Dropbox. File will be .csv format and can be renamed by user.

2) Record GPS data in a raw format.
We are interested in recording GPS coordinate measurements as fast as the iOS Device is able to generate them. The user would push a start button to start the GPS measurements, then will move around for a period of time, then press a stop button to end the GPS measurements. The data for each one of these individual test periods will be saved and exported as a file to Dropbox. User should be able to select the filename for the generated GPS file. The file format will be the same as item 1), but excluding the calibration point number. If there are any techniques to minimize battery drain (such as dimming screen, or reducing other process priorities) during measurements, we would like to try to include some of those features also.

3) Record Gyro/Magnetometer data in a raw format.
We are interested in recording Gyro/Magnetometer measurements as fast as the iOS device is able to generate them. The user would push a start button to start the measurements, then will move around for a period of time, then press a stop button to end the measurements. The data for each one of these individual test periods will be saved and exported as a file to Dropbox. User should be able to select the filename for the generated file. The file format will include all raw outputs available from the iOS device and will be saved as a .csv file.

4) Record GPS/Gyro/Magnetometer data simultaneously.
Same as items 2 & 3, but simultaneous collection. Output file format would be a combined set of columns output in items 2 & 3. The data for each one of these individual test periods will be saved and exported as a file to Dropbox. User should be able to select the filename for the generated file. The file format will be a .csv file.
