9.3.5 Real-Time Corrections with a Mobile Phone
Just as real-time corrections can be broadcast over UHF/VHF
radio and satellite signals,correction packets can be sent via
mobile phone and modem alike. Version 1.15 builds on the
current real-time capabilities of the GS20 by adding GSM and
modem capabilities.
Version 1.15 also provides support for additional RTK data
correction formats such as RTCM 18-21, Leica, and Trimble
CMR. Finally by using the Bluetooth technology, your real-
time correction system can be as small as your GS20 and
your phone.
Overview
In order to use the GSM or Modem abilities with the GS20,
you must either have a hardware device currently supported
(see list), or information concerning the AT commands for a
particular device. GSM or modem devices can be connected
to the GS20 in 3 ways:
1. Bluetooth connection directly to the GS20: Using a Virtual
BT Port.
2. Bluetooth connection via the WoRCS belt: Using Lemo or
DB9 connection.
3. Bluetooth connection directly to the GS20: Using a
modified cable with RTS/CTS leads.
This cable can also be created by modifying the existing
download cable 731354.

This will not affect the functionality of the cable for
sensor transfer or connection to external devices.
A reference station list must be defined either on the device,
or by text file which includes:
• Dial in number: Mandatory
• Reference Station name: Mandatory
• Reference Coordinates: Optional. However Reference
coordinates provides baseline data.
Finally, a configuration must be created that will reference the
device being used, the connection type listed above, and the
real-time correction format.
