"Ground" which is in systems without separate chassis Ground is the same as the "chassis" is defined as "0V common reference point". It is not negative or positive. It is the common return or common reference.
For example in a typical by-polar Op Amp schematic there will be two power supplies, Positive and Negative, such as +/-15V. GND is simply the common reference there.
