GPS-compatible indoor-positioning methods for indoor-outdoor seamless robot navigation

The difficulty of applying “pseudolites” (i.e., pseudo-satellites) and the “indoor messaging system” (MES) to indoor robot navigation is investigated. Moreover, as an alternative to these methods, “high-accuracy IMES using real-time kinematic Doppler positioning” is introduced and experimentally evaluated. The evaluation showed that this method can achieve… CONTINUE READING
