WebAbstract: In this paper, we present a new solution to GPS RAIM, called Ultra-Tight Coupling (UTC) RAIM, for both GPS fault detection and isolation. It is capable of detecting the onset of very small ramp type range biases, typically at the 0.1 m/s level, within a very short period of time following fault onset, usually under 4 seconds. This ... WebAccordingly, the INS is commonly integrated with GNSS for designing the ultra-tight coupling integration navigation system [21]. The loose coupling and tight coupling of GNSS and INS are also frequently used to improve the navigation performance of the integrated system [22]–[24]. Whereas these two do not change the GNSS baseband.
