Engineers in the automotive industry face new challenges with infotainment systems, which now introduce additional I/O like audio, video, and RF signals into systems that already have vehicle network communications and other sensor measurements. The NI PXI platform combines all measurements into one chassis to simplify this test.
The global positioning system (GPS) is a space-based radio navigation system. And the use of GPS is increasing every day. It’s important for the manufactures to make sure that GPS receivers get signals and communicate properly with connected systems.
GPS navigation is a common feature in automobiles now. Drivers rely on this to find unfamiliar locations and find the route to reach that destination. Beyond this fundamental duty of the GPS navigator, present day navigators provides many new features such as alternative route to the same location, redirecting routes, routes avoiding tolls, ferries, other points of interest etc.
There are a series of fundamental receiver performance parameters applicable to GPS systems such as sensitivity, time to first fix, reacquisition time etc. We run test cases based on all these parameters to evaluate the performance of the GPS system and thus help the manufactures to find out errors in their system and to rectify them, to provide to customers a better experience.
Automotive infotainment is generally a hardware and software platform that delivers audio and video in your car. This could be, for example, car radio broadcasting, audio and video streaming via a wireless (LTE, Wi-Fi, Bluetooth®) or wired network (HDMI, Ethernet) or even a CD or USB device.
Tuner & Media solutions in cars are becoming increasingly complex. Mobile internet, traffic information, navigation, digital broadcast and streaming services are all combined in one system. Each service requires its own antennas. To ensure the correct functionality of each part of the infotainment system and to discover sources and effects of interference, we offer a complete set of test and measurement solutions for multimedia, audio, antennas and navigation services.
With the vast number of available broadcast, wireless and cellular standards as well as different audio and video file formats and codecs, manufacturers of infotainment systems need to ensure the right functionality, even in the presence of interference.
