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.
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).
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.
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.
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.
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.
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.
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 signals. With a base of 32 channels, upgradable to 48, 64, or more, 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).
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.
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.
GSG StudioView™ offers an easy way to create, edit and back-up complex scenarios for a Spectracom 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:
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.
