RTK Implementation
configuration is well suited to surveying systems used in
base/rover configuration.
• One modem or cell phone operating in GPRS mode. The
modem is used on the rover side to establish a connection
to the Internet, either in Direct IP or NTRIP mode. The
rover will then receive RTK correction data from the
selected base. This type of data link is well suited to
surveying systems used in rover-only configuration.
Internal vs. External Modems
Depending on the model of Ashtech receiver used, modems
can be:
• Incorporated into the Ashtech receiver. Only the antenna
is visible from outside.
• External to the Ashtech receiver and connected to it via a
power/serial data cable or a Bluetooth connection.
• External to the Ashtech receiver and available as cell
phones.
Features
GSM:
• Based on TDMA technology (TDMA= Time-Division
Multiple Access). The frequency band is divided into
multiple channels which are then stacked together into a
single stream.
• Frequency bands used: 900MHz and 1,800 MHz in
Europe and Asia, 850 MHz and 1,900 MHz in North
America and Latin America.
