Overview

When the team at Renesas Electronics, an embedded design manufacturer of semiconductor processors for automotive,
decided to demonstrate the company’s new self-driving car to the Japanese media for the first time, they knew they couldn’t afford to have any problems related to Global Navigation Satellite Systems (GNSS) interference—especially after dealing with signal loss at the Consumer Electronics Show (CES) earlier this year.

That’s why they turned to NovAtel® to complete a site survey before the April media demonstration, which was held during the company’s DevCon tradeshow in Tokyo.

The Tokyo location, which is where Renesas is headquartered, presented its own set of challenges, but with help from NovAtel, the team was able to overcome them. 

Renesas has worked with NovAtel for about a year, and uses a SPAN® GNSS/INS package that includes a dual-antenna ProPak6™, an IMUKVH1750 and VEXXIS® GNSS-502 antennas to deliver a cm-level GNSS positioning, heading and vehicle orientation solution. NovAtel used the Interference Toolkit (ITK) to perform site surveys and assess the risk of GNSS interference disrupting the company’s self-driving car demo in Tokyo. The ITK was used to monitor and identify GNSS interference.

“From the technology standpoint they (NovAtel) have, from what I’ve seen, it’s the best solution available for GPS,” said Craig Johnson, Senior Manager, Silicon Valley Automotive and ADAS at Renesas. “They can support multiple channels and have a solution for loss of signal, it’s a very robust solution. And they’re very concerned about safety. If the signal fails or if there’s an issue, it indicates to the system that something failed and why. You’re not left wondering why you don’t have GPS, and that’s important for safety.”
