The Horizon IMU adds a third choice to SBG System’s Navsight Land/Air Solution. It is a FOG-based high-performance inertial measurement unit (IMU) designed for highly demanding surveying applications such as high-altitude data collection or mobile mapping in dense areas such as urban canyons. The Horizon IMU joins the Ekinox and Apogee IMUs as options for Navsight. The different levels of accuracy enable the solution to meet various application requirements and can be connected to various external equipment such as odometer, lidar and more. The Horizon IMU allows customers to use Navsight in high-altitude and highly dense areas, as well as where only a single antenna can be used. It is based on closed-loop FOG technology that enables ultra-low bias and noise levels. The Navsight solution can be installed in a plane or car — the sensor alignment and lever arms are automatically estimated and validated. The Navsight unit also integrates LED indicators for satellite availability, real-time kinematic (RTK) corrections and power. Qinertia post-processing software provides access to offline RTK corrections from more than 7,000 base stations in 164 countries.

The solution enables engineers to easily verify critical end-to-end safety-related V2X scenarios in a lab environment. It uses the C-V2X software package for the R&S CMW500 to simulate the physical- and MAC-layer, transmitting and receiving data over the simulated PC5 interface. This covers ideal, faded and congested channel conditions to the device under test (DUT). In its current form, the solution supports both GNSS and PSSS/SSSS sidelink synchronization options.
Rohde & Schwarz and Vector have successfully demonstrated its solution, which is designed to configure and run traffic scenarios to comprehensively test the physical layer 3GPP Rel. 14 up to the application layer of C-V2X ECUs in a lab environment.
Rohde & Schwarz is demonstrating the test solution at Mobile World Congress 2019 in Barcelona in hall 6, booth 6C40, Feb. 25-28.
The automotive industry is evolving toward connected and autonomous vehicles that offer many benefits, such as improved safety, less traffic congestion, reduced environmental impact, and lower capital expenditure. With the trend to equip vehicles with 3GPP Release 14 C-V2X ECUs, peer-to-peer data transfer in ad-hoc networks between vehicles will be realized. All vehicles share location, speed and trajectory, enabling warnings regarding on-road dangers to be shared between drivers.
Applications cover use cases such as vehicle-to-vehicle (V2V) communication, data exchange with roadway infrastructure (V2I), and interaction with vulnerable road users such as pedestrians (V2P). Data communication is implemented in the 5.8 GHz and 5.9 GHz intelligent transportation system (ITS) spectrum bands.
Traffic scenarios
CANoe .Car2x offers a range of functions designed to configure and run traffic scenarios. This allows the stimulation of a C-V2X control unit according to a defined traffic situation that tests the implemented application in a structured manner.
The included Car2x Scenario Editor supports the creation of traffic scenarios using a graphical interface. CANoe .Car2x generates the corresponding ITS communication based on the test scenario. The scenario is then played back with the R&S CMW500 providing the radio access layer with the specific physical interface. This verifies data transmission and reception over the PC5 interface so that the functions of the ECU can be tested comprehensively.
The combined solution covers all layers – the complete stack, 3GPP Radio Access Layers for C-V2X Mode 4, region specific ITS protocol layers such as EU ITS-G5 and U.S. WAVE and the ITS application message sets.
This enables testing of specific use cases such as Emergency Electronic Brake Light (EEBL), Left-Turn Assist (LTA) or Intersection Movement Assist (IMA), as well as more complex scenarios with multiple simulated vehicles such as a congested highway.
Additionally, security mechanisms could also be verified running simulations with both valid and invalid signed certificates. On top of this CANoe supports all common automotive bus connectivity such as CAN, LIN, MOST, FlexRay and Automotive Ethernet, enabling the test engineer to analyze or stimulate the ECU within an entire system from their desk.
By extending the solution with the VN4610 interface from Vector, customers can access IEEE 802.11p and CAN (FD) networks as well. This enables users to analyze and test C-V2X and IEEE 802.11p (DSRC) communication and related applications with a single setup and a common user interface.
“C-V2X device testing through the application layer is a significant step towards achieving the goal of having fully connected vehicles to improve road safety,” said Anton Messmer, vice president of Mobile Radio Testers at Rohde & Schwarz. “Our efforts in developing and verifying C-V2X end-to-end application scenarios are enabling user equipment manufacturers and OEMs to reduce the time needed to roll out C-V2X technology on a worldwide basis.”
“CANoe .Car2x has a strong focus on testing V2X based protocols and ADAS applications. This combined solution, CANoe .Car2x with the R&S CMW500, enables our customers to stimulate the V2X ECU with real scenario data in order to perform tests from physical layer up to the application,” said Stefan Krauß, director of Tools for Network and Distribution Systems at Vector. “The collaboration on this solution shows what can be achieved when leading players from the automotive and telecommunication industries work hand in hand.”
Testing the antenna performance of GNSS signals such as GPS, GLONASS, Beidou, Galileo and Metropolitan Beacon Systems (MBS) is key to location accuracy performance of a mobile device.

The two companies integrate the R&S LBS Server, a software component running on the R&S CMW500 wideband radio communication tester, and the Bluetest OTA test solution for A-GNSS systems based on Bluetest’s RTS65 reverberation chamber and Bluetest’s Flow measurement software.
In the test setup, the R&S LBS Server controls the Rohde & Schwarz base-station simulator R&S CMW500 for LTE, WCDMA and GSM, and uses the R&S SMBV100B vector signal generator for simulation of GNSS and MBS signals.
A simple and straightforward upgrade of the setup for 5G will be available soon, making sure that investments are protected and most relevant standards can be tested with the same system.
The R&S LBS Server is an essential part of the R&S TS8991 OTA Performance Test System. This cooperation between Rohde & Schwarz and Bluetest marks the first time that the R&S LBS Server, used here as a software tool on R&S CMW500, is available also for third parties.
“We are delighted to collaborate with Bluetest to contribute with our test and measurement expertise to OTA 4G/3G/GSM and GNSS technology development,” said Alexander Pabst, vice president, Systems and Projects at Rohde & Schwarz. “With a strong global footprint for location based services LBS and close cooperation with partners, Rohde & Schwarz is committed to accompanying the evolution path from OTA testing for GPS, GLONASS, BeiDou and Galileo with innovative test and measurement solutions.”
“The addition of A-GNSS measurements means that the full range of wireless technology in a modern cellular device can be verified with just one test solution,” said Robert Rehammar, Bluetest CTO. “Bluetest has enjoyed the close cooperation with Rohde & Schwarz on this project, leading to a very strong joint solution and customer offering.”
Rohde & Schwarz and Huawei have successfully conducted cellular-based 5G V2X latency measurements in vehicular environments in field tests in Munich and Shanghai.
In a joint project between Huawei and Rohde & Schwarz, a precision end-to-end delay measurement system for over-the-air IP transmissions was applied to 5G V2X communication for cooperative driving applications in field tests in a moving car.
The precision absolute time standards on both ends were derived from two independent GPS receivers.
URLLC will enable automated driving. (Image: Rohde & Schwarz)
The initial measurements show that it is possible to achieve delays in the millisecond regime in a 5G network, demonstrating superior latency performance in comparison to LTE.
One of the key use cases of 5G is ultra-reliable low-latency communication (URLLC). Important for advanced vehicle-to-X communication use cases, URLLC will enable automated driving in the future.
A measurement accuracy below 2 µs for each transmitted IP packet was demonstrated. The transmitted data contained various IP traffic streams including video, lidar and control data (ITS messages) for a tele-operated vehicle.
While the trial in Munich was related to a tele-operated driving project, the tests in Shanghai were related to a platoon V2X testing site, where a number of vehicles traveling together are electronically connected via wireless communication.
The delay for transmission of one IP packet from source over-the-air to a (moving) receiver (sink) needs to be measured, spanning all delays introduced by the radio transmitter, propagation delay and radio receiver from/to IP packet level.
As latency is one of the key performance indicators of 5G and crucial for safety applications, such measurements could become an important criterion for future certification testing.
“We are delighted to collaborate with Huawei to contribute with our test and measurement expertise to 5G technology development,” said Andreas Pauly, executive vice president, Test & Measurement at Rohde & Schwarz. “With a strong global footprint in the telco ecosystem and close cooperation with partners, Rohde & Schwarz is committed to further expanding our innovative test and measurement solutions to new automotive applications.”

Rohde & Schwarz has added GPS L5 and Galileo E5 simulation capabilities to its R&S SMW200A GNSS simulator.
The R&S SMW200A GNSS simulator is designed for efficient test and characterization of multi-constellation and multi-frequency GNSS receivers. With its additional simulation capabilities for GPS L5 and Galileo E5, the R&S SMW200A enables generation of complex and highly realistic test scenarios with up to 144 channels in the GNSS frequency bands L1, L2 and L5, the company said.
In addition to GPS (L1/L2/L5), GLONASS (L1/L2), Galileo (E1/E5) and BeiDou (L1/L2), the R&S SMW200A also supports signal generation for QZSS and SBAS on L1. The available channels can be routed to up to four RF outputs, so that even multi-antenna systems can be tested.
Apart from its new GNSS simulation capabilities, the R&S SMW200A can generate complex coexistence and interference scenarios with multiple interferers. GNSS signals, noise and all interference signals are generated directly in the instrument. Additional signal sources for external generation of interference signals are not required, resulting in small, compact and simple test setups.
Launched in 2017, the R&S SMW200A can be turned into a high-end GNSS simulator and is able to internally simulate complex interference environments in parallel with GNSS signals.
An increasing number of GNSS receivers are capable of receiving signals on multiple different frequencies, such as L1, L2 and L5. Although this multi-frequency capability, as well as having to process signals from diverse navigation systems such as GPS, GLONASS, Galileo or BeiDou, make the receiver design more complex, they ensure a better quality of service for the end user.
According to the company, multi-frequency and multi-constellation processing not only improves positioning accuracy, service availability and robustness, it also makes the positioning process less vulnerable to interference, jamming or spoofing attacks.
The R&S SMW200A with its new GNSS simulation capabilities will be showcased at the ION GNSS+ 2018 trade show in Miami.
