According to a report by the National Highway Traffic Safety Administration and the Auto Insurance Center, between the years 2011-2015, about 4,000 Americans died in car accidents during severe weather conditions. With these numbers, car accidents topped the list of deadliest weather hazards, overtaking floods and tornadoes.
Looking to make driving cars safer for everyone, experts are busy improving vehicle positioning technology with the use of Global Navigation Satellite Systems (GNSS) and simulators.
Such technology will not only increase the safety of travelers in unfamiliar and potentially dangerous environments, but it also has the potential to enable advanced driver-assistance systems.
GNSS constellation simulators produce GPS signals that aid in gauging the performance of navigation systems. Professionals use these simulators to work on carrier-phase differential GNSS positioning that will, in the near future, become an essential integration to LiDar and cameras to improve all-weather automated driving.
Experts are looking to improve positioning using a dense reference network that broadcasts signals to low-cost antennas within 10cm. These new systems, when realized, can provide better mapping and positioning abilities in a range of outdoor environments, including darkness and fog.
Driver-Assistance Systems of the Future
As the system also allows for precise knowledge of the orientation and position of the vehicle, the system may render intuitive driving directions on the windshield, making it appear as if there are luminous paths painted on the roadway. The driver can then follow these augmented-reality paths to reach their destination safely. The driver will also see other symbols, such as those that signal a lane change or highlight the presence of vehicles that are close by.
Rain, fog, and snow can’t affect satellite navigation signals. Therefore, experts may combine them with radar sensors to guide a driver or an automated car operating through all-weather driving.
As GNSS technology used to be exclusive to the military, such capabilities used to be a foreign concept for most civilians. Now, with the technology made available to everyone, experts seek more ways to integrate such systems into regular devices and improve the level of security for everyone.
