Project Description
In 2023, Starfire Source provided a bus company in Shenzhen with GPS satellite positioning signal amplifier equipment for the installation of indoor positioning and timing systems. Because most of the bus car park addresses are indoors or in the basement, the signal is blocked, resulting in no GPS Beidou signal, and it is impossible to position and time the bus vehicles.
In view of the large area and weak signal of the indoor car park of Bantian International Centre, we designed an 8-port GPS Beidou signal transponder coverage system to cover the floor with GPS Beidou signals to meet the positioning and timing needs of public transport vehicles.
Solution Description
This bus timing solution uses the GNSS timing antenna TIMING4100, GPS line amplifier GA40 and GPS adjustable digital stepper amplifier RGA30-DV8 to complete the forwarding and coverage of the outdoor GPS signal. The strength of the satellite signal can be adjusted to achieve the reception of GPS Beidou signals by public vehicles, positioning and timing of public transport vehicles in and out of stations.
