The invention discloses an indoor and outdoor seamless positioning method and
system based on a pseudo-
satellite technology, and the method comprises the steps: changing a pseudo-
satellite transmitting end into a receiving and transmitting
system, receiving an external
satellite signal during indoor positioning, enabling indoor positioning and outdoor positioning to be combined, and enabling the
system to be additionally provided with a reference transmitting end; and obtaining the distance and the included angle with the indoor target, so that the outdoor position can be measured in an auxiliary manner. Flexible indoor and outdoor positioning switching can be realized, a
pseudolite telegraph text is highly similar to that of a
sky satellite, normal acquisition of a
receiver is not affected, and no matter whether a positioning target is indoor or outdoor, the
receiver can normally receive signals; a special
receiver does not need to be additionally designed, indoor and outdoor
modes do not need to be switched, the system technology is simple to realize, and the
algorithm is easy to implement and high in
controllability.
