GNSS simulators emulate the environment of a GNSS receiver on a dynamic platform by modeling vehicle and satellite motion, signal characteristics, atmospherics, and other effects, causing the receiver to actually navigate according to the parameters of the test scenario. Simulation enables testing using all current and future signals and can incorporate the important edge cases that are impossible to predict in the real world. 2020 saw the introduction of multiple such simulators that improve performance and provide better results than ever before. everything RF has compiled a list of the Top 5 most popular GNSS Simulator products on the website in 2020.
LabSat Real-Time: Real-Time GPS/Galileo/GLONASS/BeiDou GNSS Simulator
The LabSat Real-Time from LabSat is a GNSS Simulator that supports GPS, Galileo, GLONASS and BeiDou constellations. LabSat Real-Time operates in real-time mode (LabSat RT Mode) or as a fully functioning record and replay GNSS simulator. It uses SatGen v3 software to generate a live signal stream to a LabSat RT unit. The unit then converts the RF data from digital to analog with less than 1second latency. The SatGen v3 software can define the position, route, speed, date, and time, as well as the number of satellites included in the data stream. It can also vary the individual carrier to noise levels for each satellite, allowing the data to be streamed directly into the device. Click here for more details.
Xidus-6HU: GNSS Simulator for Navigation Applications
The Xidus-6HU from Work Microwave is a GNSS Simulator that supports GPS L1/L2/L5, Galileo E1/E5/E6, GLONASS L1/L2, and BeiDou B1I/B2I/B3 bands. It is fully capable of multi-constellation, multi-frequency simulations for a wide range of test scenarios used in research and development of GNSS receivers, including aviation, maritime, and other navigation applications.
The Xidus GNSS simulators assure high flexibility and scalability with multiple synchronized signal modules. The Xidus hardware signal purity is retained at very high update rates. The device requires an AC supply voltage of 100 to 240 V and consumes up to 650 W of power. It has a phase noise of less than 0.005 rad RMS and frequency stability of under ±5 x 10-8 (optional < ±5 x 10-10). This simulator has 1024 multipath channels and 32 LOS channels.

BroadSim: Software-Defined GNSS Simulator
BroadSim from Orolia Defence and Security is a Software-Defined GNSS Simulator. It is powered by Orolia’s Skydel GNSS simulator engine and can simultaneously simulate multiple constellations such as GPS, GLONASS, Galileo, BeiDou, and SBAS. This simulator features an Intel i7-7700 processor, dual NVIDIA GPUs, and 64 GB of DDR3 memory which allows it to simulate hundreds of satellites in real-time.
BroadSim offers live sky time synchronization along with on-the-fly scenario re-configuration and differential GNSS & multi-vehicle simulation capability (Real-Time Kinematics). It comes with comprehensive and intuitive API (Python, C#, and C++ open-source client) along with scalable and highly flexible architecture using software-defined radios. Click here for more details.
SIMAC6: Multi-Constellation GNSS Simulator
The SIMAC6 from Accord Software & Systems is a GNSS Simulator that supports GPS, GLONASS, Galileo, BeiDou and IRNSS constellation. It is capable of multipath simulation with configuration of four multipath channels per satellite. Attenuation, doppler shift, code delay and carrier phase offset can be simulated in each multipath channel. It also allows selection of single/multiple channels of GNSS constellations with flexibility of configuring all/some of the channels for SVIDs of any constellation. The simulator supports all types of vehicle simulation via motion commands or user motion/NMEA files. Click here for more details.
SMBV100B: Vector Signal Generator from 8 kHz to 6 GHz with Fully-Fledged GNSS Simulator
The R&S SMBV100 from Rohde & Schwarz is a Vector Signal Generator with a frequency range from 8 kHz to 6 GHz. It has an RF modulation bandwidth of up to 500 MHz and provides superior performance characteristics such as high output power, wide modulation bandwidth and excellent signal quality. In A&D applications, the wide bandwidth allows the generation of complex pulsed signals. It supports internal signal generation for all major digital communication standards, including 5G NR, LTE and WLAN along with a fully-fledged GNSS simulator for GPS, GLONASS, Galileo, BeiDou and QZSS/SBA.
