Examples

MCheetah was created as a reusable mobile framework for the NSF-sponsored Mahali project http://mahali.mit.edu

App examples using MCheetah:

App
MahaliRelayApp [Code]	Purpose: Monitor Earth's ionosphere through GPS. Features: Data acquisition from multifrequency GPS receivers, multithreaded RINEX file parsing on phone, bias removal, computation of ionospheric Total Electron Content (TEC), line of sight to vertical TEC tranformation through NASA satellite ephemeris access, visualization, upload to Dropbox. AGU2015 Abstract
MagnetometerApp [Code]	Purpose: App turning a phone into a mobile magnetometer. Features: Record data in nT, upload data to Dropbox.
