Abstract
Nowadays, precision and accurate positioning in an indoor environment could pro- vide widely researched because of its variety services. There have been many position estimation techniques that can be proposed such as geometric technique, statistical technique, mapping technique and many others. Trilateration technique is the one technique of geometric technique. This technique can be estimate the target position by using the intersection of circle that can be obtained from a set of reference positions. For low-rate communication, the IEEE 802.15.4a standard is proposed. This paper studies on indoor positioning based on IEEE 802.15.4a standard in IR-UWB option. All of measurements using vector network analyzer (VNA) to measure the channel frequency transfer functions. The biconical antennas were used as both transmitter (Tx) antenna and receiver (Rx) antenna with vertical polarization. Trilateration technique will be use to estimate position related parameter RSS and TOA. From the results, TOA has the higher accuracy than RSS both low band and high band cases.
