Indoor Positioning and Timing Solution for Bus Parking Lot of Bus Zhengda City and Garden

2023.08.31

Location: Zhengda City and Garden Bus Terminal Station
Constructor: Shenzhen Xinghuoyuan Electronic Co.

Construction Date: 2023.05.08


Project Introduction
In 2023, Starburst provided a bus company in Shenzhen with GPS signal amplifier equipment for the installation of indoor positioning and timing system. Because most of the bus parking lots are located indoors or in the basement, the signal is blocked, resulting in no GPS Beidou signal, unable to locate and time the bus vehicles.
In view of the situation that the overhead floor of the bus parking lot of Zhengda City and Park is large and the signal is weak, our company designs a set of 8-port host GPS Beidou signal transponder coverage system to cover the floor with GPS Beidou signals, so as to satisfy the need of positioning and timing for bus vehicles.

Program description
This bus timing program uses GNSS timing antenna TIMING4100, GPS line amplifier GA40, GPS power splitter, GPS adjustable digital stepping amplifier RGA30-DV8 and other products to complete the transponder and coverage of outdoor GPS signals. It can realize the adjustment of the intensity of the satellite signal, and realize the reception of GPS Beidou signal by public vehicles, the positioning and timing of bus vehicles entering and leaving the station.
