GDM Monitoring GNSS Receiver
GDM is a highly integrated all-in-one GNSS receiver with low power consumption, high performance and high stability. It is based on the combination of BeiDou GNSS positioning and MEMS sensor technology, which is highly integrated and applied to the universality of field geological disaster monitoring. GDM innovatively adds camera panorama photography, which can obtain the real-time situation around the scene in the first time when the alarm occurs.
Low Power Design
Power consumption＜2W, effectively reduce the ratio and cost of solar power supply system, 100AH battery can achieve 30 consecutive cloudy and rainy days normal work.
Cloud Service functions
GDM has the self-checking function, which can regularly transfer the location, network status, signal strength, operator, number of satellites, voltage, current of power supply system, etc to the cloud platform, you can remotely restart, set, upgrade and other operations of equipment on the cloud platform.
Camera panorama
The GDM can be equipped with four cameras, which can take panoramic photos at any time to check abnormal faults in daily life and obtain the facts around the scene in the first time when early warning occurs.
