New framework PC-DeepNet uses a permutation-invariant deep neural network to minimize positioning errors in global navigation satellite systems (GNSS) in urban and sub-urban areas.
PC-DeepNet addresses challenges posed by non-line-of-sight propagation, multipath effects, and low received power levels that result in non-linear and non-Gaussian measurement error distributions.
The framework leverages NLOS and multipath indicators as features to enhance positioning accuracy in challenging environments.
PC-DeepNet achieves superior accuracy and lower computational complexity compared to existing model-based and learning-based methods.
