Abstract
An apparatus and a method for performing positioning using a Global Navigation Satellite System (GNSS) with a state machine based localization engine are provided. When the apparatus receives GNSS signals, the apparatus provides the localization engine to process the GNSS signals, and determines, based on a GNSS status and a position-velocity-time (PVT) status, a state of the localization engine. Specifically, the state of the localization engine is switchable between at least 3 states, including a dead reckoning state, a tightly coupling state, and a loosely coupling state. Once the state is determined, the localization engine may determine a local accuracy status based on the state of the localization engine. Thus, a downstream module on the apparatus may use the local accuracy status to perform a corresponding downstream action.
