Gps Repeater For Indoor Positioning

Gps repeater for indoor positioning.

A large variety of techniques and devices are used to provide indoor positioning ranging from reconfigured devices already deployed such as smartphones wifi and bluetooth antennas digital cameras and clocks. Abbree ar 889g gps position sharing 10w powerful 999ch cross band repeater dual band134 174 400 520 ham long range rechargeable two way radio. Gps repeater indoor gps amplifier gps signal booster. Optical fibre links provide a reliable way of transporting gps signals over long distances and to inaccessible locations.

An active outdoor gps antenna typically mounted on the roof of a building to pick up signals a repeater unit with a built in passive antenna used to re transmit the gps signal indoors and a coaxial cable that connects the two. If the use of gnss repeater is allowed for certain indoor environments under rf radiation regulations switching and or delaying gnss signals enables indoor positioning without any new pn code and signal generator as with pseudolites. The antenna located in the repeater unit can typically cover a radius of up to 20 metres but multiple repeaters can be used to provide coverage over a larger area. An indoor positioning system is a network of devices used to locate people or objects where gps and other satellite technologies lack precision or fail entirely such as inside multistory buildings airports alleys parking garages and underground locations.

Extends the distance from outdoor antenna to indoor repeater receiver up to several kilometres if needed. Neither do repeaters need to be synchronized. Gps repeaters do just that they repeat and reproduce the gps signal in indoors locations where signals cannot normally be achieved. Gps over fibre systems for extending the antenna feeder cable beyond the reach of coaxial cable.

Gps or gnss repeaters consist of three components. In this paper a gps repeater based indoor positioning approach is proposed. The original can be completed indoors. 4 6 out of 5 stars 27.

Unlike most repeater based indoor positioning techniques in current literature repeaters are not required to connect to an outdoor antenna with fixed length cables. Global positioning system gps based indoor positioning techniques generally utilize repeaters to amplify and retransmit the original gps signals to indoor receivers. The gps is received by the antenna the gps satellite goes from the satellite to the receiver.
