Hi-Tech Automotive GNSS Simulation Test Solution
Industry Development and Background
In recent years, the development direction of Intelligent Networked Vehicles (INVs) has become clearer, and the technological evolution has continued to deepen, demonstrating enormous market potential. At this stage, the industry has basically formed the core technology framework of "perception - communication - planning and control". Among them, GNSS positioning, as a key component of the perception layer, is currently the only sensing method that can provide absolute location information.
Typical applications such as remote vehicle control, smart cabin, in-vehicle entertainment systems, V2X Box, high-precision positioning, and V2X roadside units (RSUs) rely on high-precision GNSS positioning modules. As a result, the market demand for GNSS positioning accuracy, stability and verifiability is increasing.
GNSS Testing Status and Challenges
There are three main types of GNSS test methods in use today:
- Testing with GNSS signals in a real environment (Live Sky)
- Record GNSS signals and playback for testing (RF Record / Playback)
- Simulation and testing of GNSS signals through software or hardware
| Test Method | Real Sky Signal | Signal Recording / Playback | Signal Emulation / Simulation |
|---|---|---|---|
| Repeatable test | × | √ | √ |
| Controlled environmental conditions | × | portion | √ |
| Can be done anytime, anywhere | × | × | √ |
| Simulates future signals and events | × | × | √ |
| Realistic signal simulation | √ | √ | portion |
Most of the GNSS simulation devices in the market still have the following problems:
- Inadequate capacity to update and iterate
- Complicated software operation and long learning cycle
- High cost of traditional hardware
- Wide range of options at extra cost
- HIL simulation delay is high
Smart Internet GNSS Testing Requirements
High-performance, high-openness and cost-effective test solutions
On the one hand, smart internet vehicles need to test the performance of various types of GNSS receivers, which often involves large-volume validation, so the test system must be reproducible, controllable, easy to use and cost-effective.
On the other hand, in smart grid applications, GNSS often needs to be tested together with other modules for in-the-loop simulation (HIL). This requires test platforms with near real-time processing power, low latency performance, and flexible embedding and integration capabilities, while also catering to future upgrades and expansion needs.
Hongke GNSS simulation test program
HONGKEI has launched a complete and integrated GNSS simulation test solution for Smart Internet Vehicles, which can effectively cover the common application scenarios of GNSS receiver test, HIL test, RTK test and anti-interference test at this stage.
Based on the Skydel GNSS simulation engine, the solution constructed by Avision is based on the core concept of "relying on the software engine, opening up the hardware platform, and efficiently completing the GNSS simulation", which can provide users with a more flexible, better integrated and more forward-looking GNSS test platform, and is a truly future-oriented GNSS simulation test solution.
