Case study

Availability, integrity, accuracy and continuity of GNSS (Global Navigation Satellite System) have increased tremendously in the past decade with satellite modernization, receiver and antenna advancing and use of multi-constellation solutions. With around hundred satellites in orbit, GNSS has entering more and more areas in which accurate and always available position solution is crucial for quality of service provided. Common solution is to augment GNSS by coupling it with inertial, magnetic and barometers as sensors which provide autonomous and short-term reliable sources of motion information. One example is application of dead-reckoning in automotive scenarios.

Solution

Bitgear INS/GNSS automotive dead reckoning module is set of portable algorithms and hardware solutions tailored for accurate and continuous positioning of road vehicles in different environments and on all types of terrains. Dead reckoning algorithm is designed for low-cost MEMS inertial measurement units and standard commercial GNSS receivers with update rates from 1Hz to 20Hz. It allows different implementation complexities, from lite version portable to ultra low power microcontrollers to more advanced ARM platforms, depending on user needs.

Variants

INS/GNSS with and without digital compass; INS/GNSS with and without barometer; Output data rates 10Hz to 400Hz, depending on processing capabilities.

Applications

• insurance telematics industry,
• GNSS dead reckoning plug-in modules,
• parking solutions,
• driving behavior analysis,
• fleet management and car sharing solutions.
• Event Data Recorders
