National Geospatial Policy of India, 2022: An urban perspective
Dr Mahavir and Dr Prabh Bedi
The Policy states the use of very high- resolution satellite images (5-10 cm resolution) for urban areas. Is this really a requirement for preparing a development plan or a neighbourhood plan or an infrastructure plan? Would emphasis on excessive data lead to making of good plans and good implementation? A clear, methodical and scientific distinction needs to be drawn between land use and land cover, especially in the context of urban planning and development.... [more]

Protecting GNSS against intentional interference
Arul Elango, Ahmed Al-Tahmeesschi, Mikko Saukkoriipi, Titti Malmivirta and Laura Ruotsalainen
The disruptions to GNSS based navigation systems due to intentional and unintentional interference is a global phenomenon. Therefore, interference management techniques are crucial to mitigate interference effects. The paper provides an overview of GNSS interference sources and methods to detect it. Specifically, traditional and machine learning methods are used to detect abnormal behaviour in the GNSS signal.... [more]
