Using the GMS-2
The GMS-2 can be used as a stand-alone, L1 GPS+ receiver, or with
other devices. When installing software or performing file transfers,
the USB cable of Bluetooth module connects the GMS-2 to a
computer for in-office processing. For increased surveying accuracy,
a connected external GPS antenna or external receiver allows other
signals (such as L2 or Beacon) to be recorded.
Connecting the GMS-2 with
Other Devices
The GMS-2 provides direct connection to devices with serial or USB
port, devices that support Bluetooth wireless technology, external
GPS antennas (such as the PG-A5), and receivers that provide
correction information. The various devices are optional and can be
purchased from your local Topcon dealer, or at a commercial retail
store for commercially sold products (such as the SD card).
