Rohde & Schwarz and u-blox validate module compliance with the brand new Chinese language GNSS automotive specification GB/T 45086.1-2024

u-blox, a number one world provider of GNSS modules, and Rohde & Schwarz have efficiently validated u- blox’s newest automotive GNSS module in accordance with the not too long ago printed Chinese language GB/T take a look at requirement for automotive on-board GNSS positioning programs utilizing an automatic R&S SMBV100B based mostly GNSS simulator resolution. This cutting-edge resolution will likely be demonstrated at Cell World Congress 2025 in Barcelona.

GNSS (International Navigation Satellite tv for pc System) performs an more and more vital position within the automotive business to allow new infotainment and autonomous driving purposes. To make sure the required high quality of on-board automotive GNSS programs, the Chinese language Nationwide Automotive Standardization Technical Committee created the “necessities and take a look at strategies for on-board positioning system” pointers. Rohde & Schwarz is proud to have contributed to the drafting of the usual. These necessities had been launched on November 28, 2024 with an “implementation date“ of June 2025. Whereas the take a look at specification is at the moment solely really helpful, it’s anticipated to turn into necessary throughout the upcoming Chinese language eCall commonplace.

The automotive GNSS commonplace requires on-board positioning programs to cross a variety of necessities such for monitoring sensitivity, acquisition sensitivity, time to first repair, location accuracy and velocity accuracy, in numerous multi-constellation and BeiDou-only modes. The usual additionally defines particular occasions akin to week quantity rollover checks, leap second dealing with, radio frequency interference and surprising pseudo vary errors to check the general robustness of the positioning system. In an effort to cross the take a look at instances, the GNSS receiver should have the ability to course of indicators from two frequency bands concurrently.

Lots of the checks can’t be carried out in a real-world setting with reside GNSS indicators since they’re troublesome to implement, time-consuming, expensive and not possible to breed. That is the place the Rohde & Schwarz resolution turns into important. These checks could be carried out with R&S SMBV100B GNSS simulator within the lab underneath managed and repeatable situations. It supplies superior simulation capabilities for configuring lifelike and complicated, but repeatable GNSS eventualities that may be run underneath managed situations. Along with the R&S CMWrun sequencer software program, a R&S NGC101 energy provide and the R&S SMBVB-K364 software program choice, the R&S SMBV100B turns into an automatic take a look at resolution executing the take a look at sequence and offering a cross/fail consequence in addition to take a look at experiences. The take a look at resolution is of particular curiosity to GNSS silicon suppliers, GNSS module suppliers, Tier1 builders of Telematic Management Models (T-Field in China) and infotainment programs certification firms and automobile OEMs promoting to the Chinese language market.

For the automotive ecosystem to validate compliance to this new take a look at specification in an automatic, standards-compliant, repeatable and well timed method, cooperation between suppliers on this business turns into more and more vital. To this impact Rohde & Schwarz is happy to co-operate with u-blox. Gerald Tietscher, Vice President Sign Turbines remarked: “We’re delighted to collaborate with u-blox to allow the automotive positioning ecosystem with a strong, commonplace compliance and automatic resolution to validate their merchandise towards the rising Chinese language GNSS commonplace.”

This partnership enabled pre-compliance checks throughout the u-blox portfolio of automotive GNSS receivers, together with the ZED-F9L and ZED-F9K, in addition to the upcoming u-blox 20 product household. Andreas Thiel, Head of Enterprise Models, and Co-founder at u-blox AG, remarked: “We’re happy that Rohde & Schwarz chosen u-blox and our EVK-F9DR as reference package to showcase this new automated take a look at resolution. With R&S superior testing instruments, automotive firms focusing on the Chinese language market can seamlessly validate their u- blox-based on-board positioning programs towards GB/T 45068 and different requirements.”

The take a look at setup will likely be proven on the Cell World Congress in Barcelona, from the March 3 to March 6, 2025, on the Fira Gran Through, in Corridor 5, sales space 5A80.
