GSG-51 Single Channel GNSS Tester

Single-channel GPS/GNSS L1 RF Generator

The GSG-51 is a GNSS signal generator that emulates a single satellite signal. The main application is a simple but very fast manufacturing test, to assure that the assembly is correct, that the antenna is properly connected, and that the receiver can receive and identify a satellite signal. It provides a fast and cost-effective solution for production test of GNSS-receivers in e.g. mobile phones with integrated GNSS-receivers. Thanks to the wide RF level range from –65 to –160 dBm, the sensitivity of all types of GNSS receivers can be veriﬁed with a minimum of delay. The 60 dB of extra power from normal test scenarios allows from splitting the signal many times.

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.

GSG-5 Series Multi-channel Essential GNSS Simulator

Multi-channel GPS/GNSS L1 RF Generator

The GSG-5 series is a GPS, GLONASS, Galileo, BeiDou, and QZSS constellation simulator that generates all commercial signals in the standard L1 band. It offers the standard set of features for testing GNSS systems. With a base of four channels, configurable and upgradable to 8, 16, or more signals, this configuration is the perfect fit for navigational ﬁx and position testing, for in-line product testing or engineering and development.

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 complex scenarios, independent of the unit, for later upload.

GSG-6 Multi-Channel, Multi-Frequency Essential GNSS Simulator

Multi-channel, Multi-Frequency GPS/GNSS RF Generator

The GSG-6 Series family offers multiple frequency band operation, multiple GNSS constellation simulation, and expansion to many more channels. Incorporating all of the features of the popular 5 Series family, the 6 Series line expands your capability to simulate all the new, emerging GNSS satellite signals. With a base of 32 channels, upgradable to 48 or 64, it provides navigational ﬁx and position testing, for engineering and development testing. The 6 Series simulator protects your investment by being upgradeable in the future to more frequency bands and channels (plug-in hardware upgrade) and more signal formats (ﬁrmware upgrade).

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.

Currently the GSG-6 series also supports GPS signals L2C, L2P and L5; GLONASS L2; Galileo E5a, E5b, and E6; BeiDou B2I, B2a and B3; NavIC L5; QZSS L2C, and 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.

GSG StudioView Software

GPS/GNSS Test Scenario Builder Software for Windows®

GSG StudioView™ offers an easy way to create, edit and back-up complex scenarios for a GSG series multi-channel GPS/GNSS simulator. GSG StudioView allows users to build and manage visual trajectories and supports the import and conversion of trajectory files from other software applications and devices such as Google Earth.

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.

White Papers
Testing GNSS Receivers to Harden Against Spoofing Attacks More Info Spoofing is an attempt to deceive the GNSS/GPS receiver by broadcasting signals that the receiver will use instead of the live sky signals. This article describes a test system for spoofing allows testing the three major factors to consider in a spoofing attack, time synchronization to the signals to be spoofed, power level of the spoofing signal compared to the live sky signals, and accuracy of the position obtained by the spoofing signal to that of the actual position of the device being spoofed. Using a spoofing test system will allow a user to better understand the receiver and harden the system against spoofing attacks.	pdf - 673 KB Tuesday, December 8, 2015 [ Permalink ]
Zone Based Indoor Location Using GNSS Simulators More Info Signals from Global Navigation Satellite Systems (GNSS), such as the Global Positioning System (GPS), are very weak and usually cannot be seen indoors or underground. A common method to overcome the problem of receiving GNSS signals indoors or underground is to use a GPS/GNSS repeater with an antenna located outdoors to receive the GNSS signals and an amplifier/antenna to re-transmit the signal indoors. This paper describes the technologies and methods for creating an intelligent repeater system including time synchronization at the nanosecond, microsecond, and millisecond levels, how each synchronization level affects the overall system and methods for achieving each, power level considerations including power level requirements between zones and how they affect transitions from one zone to another, data transfer and example system configurations. While GPS is primarily demonstrated and tested, the possibility for adding other GNSS constellations such as QZSS, BeiDou, Galileo, and GLONASS are also presented.	pdf - 270 KB Wednesday, November 18, 2015 [ Permalink ]
