The total in-car navigation market has been in continual decline for the last three years, but ABI Research believes it has now reached its lowest ebb. While pure navigation is unlikely to reach the highs of 2008 again, the overall market is reaching a revenue plateau, creating a solid platform on which connected in-car services can bring a new generation of revenue growth, the market research firm concluded.
Telogis, Inc., a platform for location intelligence, has acquired Navtrak, a mobile resource and fleet management company. This latest acquisition, along with the company’s strong organic growth rate, further positions Telogis as a fast-growing enterprise Software-as-a-Service (SaaS) provider of location-based intelligence solutions, the company said.
It wasn’t quite a call to arms, but Bill Ford, head of Ford Motor, called on the wireless community to work with car makers to avoid global gridlock and create a future of “urban mobility,” a network that will track vehicles and automatically instruct cars to change lanes, exit a road, or park. Vehicle connectivity was one of the major themes of the Mobile World Congress, held in February in Barcelona. For some of us, it brought up memories of the PATH automated highways project of the 1990s. You have likely seen photos of that prototype automated highway with platoons of driver-less vehicles riding on I-15 in southern California. The vision has changed, and we are headed towards autonomous, connected vehicles and away from the specialized, and prohibitively expensive, infrastructure that defined earlier efforts.
Future safety-relevant driver assistant systems demand vehicle state estimations accurate enough to match the position within a road lane, which cannot be provided by standalone GPS. A promising approach to meet the requirements is the fusion of standalone or differential GNSS measurements with vehicle sensor data like odometers or accelerometers. To achieve deeper sensor integration, a software GNSS receiver was developed at the Institute of Flight Guidance (IFF) that is able to use dead reckoning sensors to support its signal acquisition. This article presents an approach to estimate the signal states during outages based on the tightly coupled vehicle state, which reduces the reacquisition time and significantly increases the signal availability.
