Global Data Burst (GDB) has combined its expertise in satellite paging with its knowledge of conventional paging to produce a unique product that brings together the best features of both technologies. GDB Repeat allows standard, low cost VHF pagers to receive messages anywhere on earth!
Our system accepts a conventional paging request, broadcasts it by satellite to one or more GDB Repeat units on the ground where it is re-transmitted as a conventional VHF paging message.
GDB Repeat is also ideally suited to setting up new networks and eliminates the need for any ground-based telecoms services. GDB Repeat can be installed easily and become operational quickly. If environmentally-friendly power sources are used (solar cells or wind turbine), there are no constraints on installation location.

HOW DOES IT WORK?
Our simple interface allows an operator or a system to send in a VHF paging message. We take the message, convert this into a satellite message, route the message to the correct satellite where it is then sent to the GDB Repeat unit on the ground. The GDB Repeat unit then decodes the satellite message and converts it back to a VHF paging message and re-broadcasts the message using its built-in VHF paging transmitter.
