Abstract:The state-of-art Local Area Augmentation System (LAAS) system for 21st century is being developed by USA, to provide aircraft precision approach and landing. In India, LAAS is still in conceptual stage. Prominent error sources namely ionosphere, troposphere, multipath and receiver noise affect LAAS performance. LAAS employs Single Frequency Carrier Smoothing (SFCS) to mitigate spatially uncorrelated errors like multipath and thermal noise. Temporal and spatial gradients of ionosphere affect the performance of … Show more
