R51 Wide application integrated GNSS receiver

R51 Ubiquitous GNSS Receiver is based on GNSS high-precision positioning technology, MEMS sensor technology, 4G communication technology and single chip system technology research and development.

The whole system adopts a plug-in design, which greatly simplifies the installation process and improves work efficiency.

R51 is a low-power dedicated receiver for field geological disaster monitoring. Optional built-in lithium battery, solar panels are available.

The R51 universal GNSS receiver can be used with a third-party cloud platform to realize remote monitoring and management of equipment in the cloud.

Application field: can meet most needs of bridges, dams, mines, deformation monitoring
