(2) The motor position is sampled from the VESC motor controller at 100 Hz and combined with the estimated heading from the position filter to calculate a relative dead reckoning
In order to reduce error accumulation, odometry or the self-resetting method can be used for dead reckoning
. On a slippery or uneven floor, odometry can cause large unpredictable positioning errors.
Wheel slip causes perturbations in robot velocity measurements leading to performance degradation of dead reckoning
based localization methods.
Crowds did not go to hear Gandhi armed with guns rods and spears." (Sarmila Bose Dead Reckoning
: Memories of 1971 Bangladesh War Page 26)
The key idea behind dead reckoning
is that predicting the position of an object makes it unnecessary to receive an update for that object's motion every time it moves.
Gone are the days of flying across the Pacific Ocean using dead reckoning
navigation without GPS, INS, or stellar navigation updates.
We've come so far from the days of A/N ranges and dead reckoning
The science of navigation; from dead reckoning
The AoA will address the viability of current and emerging technologies to provide PNT information under conditions where GPS is not available such as advanced antennae technology, pseudo-satellites, Radio Frequency Navigation, and Autonomous (e.g., Inertial, MEM IMU, Dead Reckoning
Remember that ocean current and wind make it nearly impossible to accurately fish a specific position, in open water, by dead reckoning

Their topics include Bayesian updating, representations, computation, data structures, the nature of learning, dead reckoning
in a neural network, and the molecular basis of memory.
