Cohda's DSRC (Dedicated Short-Range Communications) based V2X system uses accurate satellite positioning with embedded dead reckoning
technology provided by u-blox.
u-blox' dead reckoning
solution, powered by the LEA-4R GPS module, is ideal for applications that require continuous positioning such as vehicle navigation, fleet management and toll systems.
SiRFDRive for SiRFstarV 5ea now also includes CSR s latest dead reckoning
algorithms that work alongside concurrent GPS and GLONASS operations.
u-blox' dead reckoning
technology uses additional sensors that detect travelled distance with an odometer and turn rate using a gyroscope, supplementing GPS data and thus providing an accurate position in tunnels, indoor parking facilities, roofed logistics centers, urban canyons and any other environment where obstructed GPS signals hinder positioning.
In 1707, after a maritime disaster caused by an incorrect calculation of a fleet's position (``guess'' is more appropriate, as navigators had no way of really knowing then, using dead reckoning
and an unreliable method of computing knots), the British Parliament offered a sum of 20,000 pounds (about $5 million today) to anyone who could solve the problem of finding longitude at sea.

However, GNSS technologies will have to be combined with other positioning solutions such as A-GPS, Wi-Fi, and dead reckoning
to address the indoor coverage issue.
That was the hope Saturday as about a dozen rover robots roamed the beach while scientists from around the globe talked of autonomous navigation, pitch-and-roll clinometers, rocker-bogie chassis and encoders for dead reckoning
Leveraging Analog Devices' iMEMS[R] Motion Signal Processing Technology[TM], the ADIS16355 inertial measurement unit (IMU) allows industrial designers for the first time to equip their systems with sophisticated motion analysis and navigational dead reckoning
functions previously reserved for defense, aerospace, and other high-end applications, at approximately one tenth of the cost.
NEW ORLEANS, May 8, 2012 /PRNewswire/ -- Trimble (NASDAQ:TRMB) introduced today the Aardvark DR+GPS module that combines Dead Reckoning
(DR) with Global Positioning System (GPS) technology on a single, compact board.

The IDG-1004 enables dead reckoning
(DR) and better map matching capability by measuring the direction of the vehicle with one axis, while providing better distance accuracy by measuring slope as the vehicle travels up and down hills or in rough terrain using the second axis.
