1.1 Quick Start
The following procedure is a brief outline on how to get started with your GSG-5/6 unit.
The minimal setup steps are:
1. Unpack the unit (see "Unpacking and Inventory" on page14), and place it on a
desktop or install it in a rack, as described under "Mechanical Installation" on
page15.
2. Connect the receiver antenna cable to the RF Out connector on the front panel.
(See also "Electrical Installation" on page22.)
3. Connect the power cable to a wall socket. Press the ON/OFF key to start the unit.
4. The GSG display will show the Start view: Verify that the right-hand side shows an
overview of a test scenario (name, date, lat/long/traj, etc.).
5. If no scenario is shown, use the arrow and enter keys to select Select from the main
menu. This will open up a list of pre-defined scenarios. Select one of the scenarios
from this list.
6. Press the start key to begin with the scenario execution.
7. Start the GNSS receiver you want to test.
Note: It may be necessary to clear the memory of your GNSS
receiver, i.e. erase old data. This is typically referred to as a Cold
Start , where any ephemeris data and almanac data are removed
from the receiver’s memory.
8. Your GNSS receiver under test should see and track the generated signals. If the
receiver could successfully decode the navigation data included in the signals (this
process often takes approximately 40 seconds), the receiver will output the nav-
igation fix as specified in the selected scenario. This navigation solution should cor-
respond to the solution shown on the GSG-5/6 display.

About Orolia's GNSS Simulators
The GSG-5™ and GSG-6™ Series of GNSS Constellation Simulators provide a wide-range
of capabilities for in-line production testing and development testing, including navigational
fix and position testing, while offering ease-of-operation.
GSG-51 is a single-channel GPS L1 RF generator, capable of emulating a single GNSS sig-
nal. One of the main applications for these cost-effective units is fast manufacturing testing
of GPS receivers.
GSG-5 Series simulators reproduce the environment of a GNSS receiver. Depending on
the configuration, these units simulate up to sixteen GNSS satellites, up to 3SBAS satel-
lites, together with optional multipath and interference signals. The GSG-5 Series applies
models to simulate satellite motions, atmospheric effects, and different antenna types. The
movement of the GNSS receiver under test is defined using NMEA data or pre-defined tra-
jectory models.
GSG-6 Series simulators add advanced features and the capability to simulate up to 64
satellites (configuration-dependent) on different frequency bands simultaneously. New sig-
nal types include GPS L2P, L2C and L5, GLONASS L2, Galileo E1 and E5a/b, BeiDou B1
and B2, and QZSS L1 C/A, L2C, L5 and L1 SAIF, IRNSS L5.
1.3 Key Features
Since GNSS testing requirements may vary considerably from application to application,
GSGSeries simulators are available in a multitude of configurations (see "GSG Series
Model Variants and Options" on page203).
Some of the key features are:
1.2 Welcome

High accuracy time base
GSG Series simulators offer a front panel display with an intuitive software User Interface,
allow for remote Web-based operation, and include GSG StudioView™, a PC-based soft-
ware with Google Maps™ interface to create custom scenarios.
1.4 Typical GSG Applications
GSG-5/6 Series GNSS Simulator are often used for the following testing applications:
Basic Receiver Testing
Time-to-First-Fix (TTFF): How fast can a GNSS receiver obtain a position fix after
a cold start.
Reacquisition Time: How fast can a GNSS receiver get a fix after a hot or warm
start.
Location: Test position accuracy at different locations in the world.
Sensitivity: Acquisition and Tracking Sensitivity
Noise Susceptibility: SNR limit testing
Advanced Receiver Testing
Trajectories: Test receiver while moving
1PPS: Verify the receiver timing accuracy
Leap Second: Test the leap second handling of the receiver
Multipath: Perform basic receiver tests under multipath conditions
