Topic: Track inside tunnel
Hi,
Do anybody have experience in using gps trackers which can capture data inside tunnel or where there is no GPS signal.
One of my customer is into excavation and tunnel boring and a couple of trucks, machineries and passenger buses, pick ups etc spend max 6-12 hours a day inside the tunnel and will come back to the accommodation at the end of the day, and they wish to know the activities happening inside the tunnel like, speed, idling, ion on/off status etc
Regards,
Abraham
