Trimble and Sirius XM Connected Vehicles Services Inc. announced that Trimble RTX® GNSS corrections are being transmitted through the SiriusXM® satellite radio network. As a result, new cars sold in the contiguous U.S. and Canada equipped with SiriusXM’s Gen8 satellite chipset will be able to receive RTX GNSS corrections enabling high-accuracy positioning—a key component of autonomous on-road applications.
With the simple addition of the Trimble RTX Auto™ software library, any new vehicle that receives SiriusXM broadcasts with a Gen8 satellite chipset can leverage a positioning solution ideal for Advanced Driving Assistance Systems (ADAS), Autonomous Driving (AD) and Vehicle-to-Everything (V2X) applications.
Since the SiriusXM hardware is already installed in most new vehicles, automotive OEMs can avoid the cost of additional hardware to receive GNSS positioning corrections.
RTX technology is a critical component of General Motors’ Super Cruise™ system. To date, Super Cruise and Trimble RTX have enabled over 5 million miles of hands-free driving on America’s roadways.
Trimble RTX technology provides real-time, multi-constellation correction of GNSS observations to provide significantly more precise position estimates. Standard GPS signals can drift up to 25 feet, which could cause incorrect lane identification. When used in conjunction with high-definition maps, cameras, radar and inertial sensors, Trimble RTX provides lane-level positioning performance for semi-autonomous and autonomous vehicles.
