Dense urban environments, parking garages and multi-level interchanges impair satellite navigation signals - dead reckoning provides the solution.
u‑blox Dead Reckoning solutions make use of multiple sensor inputs and fuse them with GNSS signal data to bring superior positioning performance to any road vehicle application, line fit as much as aftermarket. There are two variants:
Automotive Dead Reckoning (ADR) makes use of motion sensors and vehicle wheel/speed data to achieve the 100% coverage, highest‑performance positioning solution available in the industry, perfect for all road vehicle high‑accuracy navigation applications with access to the electrical vehicle data.
Untethered Dead Reckoning (UDR) needs only local motion sensors to achieve superior positioning performance in a majority of cases, perfect for all road vehicle applications without access to the vehicle data, bringing unprecedented performance to aftermarket applications.
