OTA-Measurements

Currently available OTA test systems and measurement techniques are ill-suited for large vehicles and the automotive industry’s growing demand for system performance analyses. To address this, ATC has begun developing a process to evaluate automotive antennas in real-world environments using drive tests. This technique uses existing 4G mobile network infrastructure in real environments to show how good is the user experience of your antenna system. Neither the size of vehicle nor a lack of investment capital hinders the ability to characterize 4G systems using this technique.

Sirius-XM

Nationwide reception in best radio quality, where terrestrial radio services like AM, FM or DAB reach their limits – this is what satellite radio stands for, such as SiriusXM in the USA. ATC GmbH is an independent, certified contact in Europe.

Ultra Wide Band

A very exciting application of ultra-wideband technology is the exact positioning of objects at distances of up to 250m. It is currently attracting great interest not only from automotive manufacturers. In the following we describe the special challenges of position determination from the point of view of the antennas used.

GPS (GNSS) System Evaluation

“Waiting for GPS…”, “GPS signal not found”, “No GPS reception”, “Position determination not possible”, this or similar error messages can look like this, which are annoying for the user on the one hand and can impair autonomous driving on the other hand.

EMC - Root Cause Analysis

As soon as a significant deviation in interference emission or in interference immunity of EMC tests is detected, question arises not only about a possible solution, but always about actual cause. In many development departments, the trail-and-error method is then used to find a quick solution. The actual physical cause usually remains hidden.
