/// \par Overview
///             This library parses and decodes the TSIP data stream from a Trimble GPS
/// and stores the position, velocity, and time solutions in the gps.c library.
/// The library also includes functions to transmit TSIP packets to the GPS for 
/// configuration and data request.
