Configuration; Configuring The Internal Uhf Modem / Gsm Module - Javad TRIUMPH-1 Operator's Manual

6. Configuration

Both Base and Rover receivers must be configured according to the desired survey method.
• In applications where real-time positioning results are required, the Base receiver provides the
correction information needed to properly calculate the location of the Rover receiver. A Base
station is normally set up over a known point and collects GPS/GLONASS data from satellites.
As the receiver picks up satellite data, it measures the carrier and code phases to accurately
compute and verify its location. Then, the receiver transmits this information via radio (UHF or
GSM) to the Rover receiver.
• The Rover receiver applies correction information from the Base station to its current location to
accurately calculate one or more points. Rovers are mobile GNSS receivers on a survey pole or
bipod that compares the information from the Base station to the data it logs from satellites and
applies correction algorithms to accurately calculate a new point.
• In applications intended for post-processing, the receivers typically log code phase and/or carrier
phase measurements separately from common satellites and during the same time interval. This
data is then processed using post-processing software (for example, Justin).
When configuring receivers for RTK surveying, use the following list to ensure the receivers are properly
set up:
• Configure one receiver as an RTK Base station and the other receiver as an RTK Rover. See
"Configuring the Receiver" on page 40.
• Configure the communication data link for transmitting and receiving corrections.
• For a modem, see "Configuring the Internal UHF modem" on page 33.
• For a GSM module, see "Configuring the GSM module for Point-to-Point radio link" on page 34
and "Configuring the GSM module for Internet access" on page 36.
• Set up the Base receiver over a known point to begin collecting static observation data and
transmitting corrections. Set up the Rover receiver to begin collecting RTK data.
When configuring receivers for post-processing surveying, use the following list to ensure the receivers
are properly set up:
• Configure one receiver as a Base station and the other receiver as a Rover. See "Configuring the
Receiver" on page 40.
• Set up the Base receiver over a known point to begin collecting static observation data. Set up the
Rover receiver to begin collecting static or kinematic observation data.

6.1. Configuring the Internal UHF Modem / GSM Module

Use free JAVAD GNSS software ModemVU for configuration of embedded TRIUMPH-1 modems.
ModemVU provides the following functions:
• Connecting a computer to an integrated UHF modem via a serial port or Bluetooth® wireless
technology.
• Displaying information about the radio modem installed in the receiver.
