Abstract
The paper describes a parallel genetic algorithm for the
VLSI implementation of real-time GPS attitude
determination systems. The genetic algorithm is based on a
fine-grained model and utilises AFM (Ambiguity Function
Method) for GPS attitude determination. The paper
describes various implementation choices with for the
genetic algorithm in order to achieve both functionality and
practical performance constraints such as speed,
compactness and scalability. Simulation results using GPS
carrier phase experimental data show that, in addition to low
