Autonomous Positioning using Doppler Aided Inertial Navigation™ (DAIN)

SCP technology makes it possible to provide reliable, consistent, and accurate indoor positioning without the support of network infrastructure and services.  By exploiting freely available signals including GPS, cellular, digital television, and wireless LAN (e.g. WiFi), SCP based Doppler Aided Inertial Navigation (DAIN) determines location through a sensor fusion approach.  Combining inertial, magnetic, and gravity data with the SCP RF observables, DAIN provides continuous position, velocity, and direction information.

A fundamental breakthrough in indoor positioning, SCP DAIN is ideal for emerging location enabled applications hosted on smart phone devices.  The technology delivers unprecedented performance in a cost-effective, software-based solution.  SCP DAIN is a compelling augmentation to outdoor GPS, delivering GPS-like accuracy indoors.

DAIN is an ideal enabler for both consumer and commercial applications.  The autonomous operation capability is well suited for multi-sensor devices incorporating SCP sensor technology.  No additional network infrastructure is required, making it possible to operate in virtually any environment.
