GSG 5/6 Series GPS/GNSS Simulators

Easy to Use

GSG-51 users can configure settings without the need for an external PC and pre-compilation phase. Via the front panel, the user can swiftly modify parameters such as satellite ID, time and power output. The front panel can be locked out to prevent accidental power down or configuration changes. Once initiated the unit can simulate for 31 days continuously (or indefinitely if the unit is connected to the internet).

Flexibility

As the base model of the popular 5 Series GNSS Simulator family, this affordable unit can be upgraded at any time after purchase to increase the channel count, add receiver trajectory control, and add advanced features such as SBAS (WAAS, EGNOS, MSAS, or GAGAN), white noise generation, or multipath simulation. Some restrictions apply. Your investment is protected as you can purchase now, and upgrade later, as needed, when your requirements change.

Easy to Use

GSG-5 users can configure scenarios on-the-fly without the need for an external PC and pre-compilation phase. Via the front panel, the user can swiftly modify parameters such as user position, time and power output. And using the StudioView™ software facilitates easily created scenarios via a Google Maps interface.

Flexibility

As the base model of the popular 5 Series GNSS Simulator family, this affordable unit can be upgraded at any time after purchase to increase the channel count, add new GNSS constellations and advanced simulation capabilities. Some restrictions apply. Your investment is protected as you can purchase now, or upgrade later, as needed, when your requirements change.

Connectivity Extends Ease of Use and Flexibility

The GSG-5 can be controlled via an Ethernet network connection, USB or GPIB. A built-in web interface allows complete operation of the instrument through front panel controls. With the GSG StudioView™ PC Software, you can build, edit, and manage the most complex scenarios, independent of the unit, for later upload.

All the features of the GSG-5 series and more

The GSG-6 series offers more channels and GNSS signals on multiple simultaneous frequencies. For example, the GSG-6 supports testing dual frequency (L1/L2) receivers and military secure SAASM modules with pseudo P(Y) code with M-code coming soon.

Currently the GSG-6 series also supports new GPS signals L2C, L5; GLONASS L2; Galileo E5; BeiDou B2; and IRNSS L5.

An ideal solution for testing GPS time transfer

Besides the variety of built-in navigation/positioning tests, the GSG-6 is also suited for testing the accuracy of timing receivers. All GSG models are equipped with an ultra-high-stability OCXO timebase for precision timing of the satellite data, or use external synchronization from a 10 MHz reference from e.g. a Cesium or Rubidium clock. A built-in 1-pps output, synchronized to the generated satellite data, allows comparison with the 1-pps signal from the timing receiver under test. And the OPT-TIM option provides a ten times improvement in timing calibration accuracy.

There are 3 hardware configurations of the GSG-6 Series

Each configuration adds 16 channels and another frequency that can be simultaneously simulated. You can upgrade models by returning the unit to the factory.

• GSG-62: 32 channels and 2 simultaneous frequencies
• GSG-63: 48 channels and 3 simultaneous frequencies
• GSG-64: 64 channels and 4 simultaneous frequencies

Notes:

• GPS and L1 is included and the second frequency and other constellations are ordered from the list of available options.
• You can order more frequencies than the unit is capable of generating simultaneously in the case of testing L1+L2 and then later testing L1+L5.
• You do not need to order as many frequencies as the unit is capable of generating in the case of ordering the hardware to generate multiple frequencies, and then ordering frequency options later as a firmware upgrade without the need of returning the unit to the factory.

Even though the ability to manage scenarios without the need of an external computer is an advantage of GSG simulators, StudioView Windows® software offers the following benefits for the test engineer:

• Simple creation, editing and organization of all scenario parameters including dynamic events
• Create, edit and visualize trajectories with mapping tools
• Convert trajectories from CSV, KML, KMZ and GPX files to the required NMEA format
• Create scenario files (including events and trajectories) without the need to be connected to a simulator

Easy Trajectory Building and Dynamic Event Management

A key feature of GSG StudioView is the ability to create and modify the simulation of a moving receiver. Easily create visual trajectories with Google Maps. Or import trajectories from most other software applications and devices such as Google Earth. The software converts a list of waypoints from a CSV file, or waypoints, routes and tracks from a GPX file (GPS exchange format) into NMEA as required by the unit. Google KML and KMZ files can be opened, edited, and saved. Each waypoint can be specified. When converting a trajectory file to NMEA format, you specify altitude and speed at each waypoint or use a constant value for the trajectory. Trajectory waypoints can be interpolated at a set interval from 100 msec to 1 hour.

Download Ephemeris and Almanac Data

Based on the scenario start time and duration, GSG StudioView software identifies and pre-downloads the relevant RINEX files from official websites. Once the scenario is uploaded to the simulator, no further downloads are required.

Simple File Management and Control

When ready to upload (or download) the scenario files to any GSG unit, simply connect through the network, USB, or GPIB interfaces and use the built-in file manager. Drop and drag files, use predefined hotkeys for copy, delete or rename either on the PC side or the GPS simulator side. Or use the "uploader" to batch upload scenarios, or firmware files, to several units simultaneously. Also included is "console" function to send SCPI commands to a connected unit, and view the response. The software comes standard with multi-language support. English and Russian are currently supported. Contact us if other languages are desired.
