Because of the MEMS inertial sensors being more and cheaper, most studies focus on their applications. It is known that the simple principle and construction of the MEMS accelerometer make it is possible to improve the performance of MEMS accelerometers faster than that of gyros, so most efforts are done to use only the linear accelerometers forming the IMU called IMU-BA which has the potential market in the land and air navigation system, such as the car…

Indian NSDI publishes Metadata Standards ver 2.0

The National Spatial Data Infrastructure (NSDI), under Department of Science & Technology of Government of India, has released Metadata Standard 2.0. It is prepared by the working group on ‘Metadata Standards’ chaired by Dr. S K Pathan, from Space Applications Centre (SAC), ISRO, Ahmadabad. The National Natural Resources Management System (NNRMS) Metadata Standards defines the schema and design for the NSDI Metadata. It also contains a set of relational tables that standardise the layer metadata, the geographic search metadata, the access metadata etc.

Metadata is the first element of the NSDI, which enables a user to find spatial data that is available in different NSDI Agency servers. It serves two major purposes – both for the spatial data generator and for the spatial data user. For the generator, it provides a framework to document the spatial data and declare its content for users. For the user, it serves many important purposes, including finding the spatial data as per need; browsing spatial data; deciding on whether the spatial data will meet the application need and finding how the spatial data can be accessed.

ISRO, with the involvement of Survey of India, National Informatics Centre, Geological Survey of India, Forest Survey of India, National Bureau of Soil Survey and Land Use Planning, National Atlas and Thematic Mapping Organisation, Central Ground Water Board, Central Water Commission and the private sector, has led the effort of defining a ‘National Metadata Standards’. http://www.nsdiindia.gov.in

Obama proposes terminating system that backs up GPS

In his fiscal 2010 budget, President Obama killed funding for a system that would back up the much relied on GPS if it failed, despite calls from the telecom industry and federal agencies that it is needed. The Homeland Security Department (DHS) endorsed Loran-C a year ago as a backup for the satellite-based GPS, but in its fiscal 2010 budget, the department zeroed out funding for the system. www.nextgov.com

The effort for realizing fully autonomous and operative Unmanned Aerial Systems (UAS) induced the need of developing innovative techniques for integrating measurements derived from different aircraft navigation systems. Since no human aid is available onboard UAVs, navigation hardware must attain larger capabilities than the ones of manned platforms. In particular, the most important features that shall be considered are autonomy, safety,…
