“…Therefore, providing seamless positioning services connecting indoor and outdoor environments has become a critical issue. There are many indoor positioning technologies, such as integrated navigation, 17 ultra wideband (UWB) positioning, [18][19][20] assisted global navigation satellite system (AGNSS), 21,22 high-sensitivity GNSS, 23 and WIFI positioning, [24][25][26][27] but these positioning methods all have their limitations. 28,29 AGNSS and high-sensitivity GNSS technology are extremely complex, and they can only solve the positioning problem of ''shallow indoor environment''; some researches use pseudolites to provide indoor time of arrival (TOA) positioning, but they are still limited by non-line-of-sight (NLOS) and multipath problems.…”

People have to move between indoor and outdoor frequently in city scenarios. The global navigation satellite system signal cannot provide reliable indoor positioning services. To solve the problem, this article proposes a seamless positioning system based on an inverse global navigation satellite system signal, which can extend the global navigation satellite system service into the indoor scenario. In this method, a signal source is arranged at a key position in the room, and the inverse global navigation satellite system signal is transmitted to the global navigation satellite system receiver to obtain a preset positioning result. The indoor positioning service is continued with the inertial navigation system after leaving the key position. The inverse global navigation satellite system seamless positioning system proposed in this article can unify indoor and outdoor positioning using the same receiver. The receiver does not need to re-receive navigation information when the scene changes, which avoids the switching process. Through the design of signal layer coverage, the receiver is in a warm start state, and the users can quickly fix the position when the scenario changes, realizing quick access in a true sense. This enables the ordinary commercial global navigation satellite system receiver to obtain indoor positioning capability without modification, and the algorithm can perform accurate positioning indoors and outdoors without switching.
