Phase centre is defined as a point (or a set of points) in space from which, when emitted, far-field phasefronts or, correspondingly, group-delay fronts are spherical or substantially spherical [1-2]. That is, the phase value is constant in a certain angular area of interest when measured with respect to the coordinate system whose origin is in the PC. However, PC is ambiguous for most of the real-life antennas and its position varies for…
Ground Penetrating Radar (GPR) provides a picture of the different materials or structures underground up to a few meters of depth. To provide a 3D map of underground objects such as pipelines, the georeferencing horizontal tolerance should be around 20 cm, a figure achievable by GNSS systems. The conditions of GPR urban surveys, though, make it impossible to rely on GPS alone for positioning. In front of large blocks…
GIS was first introduced in Malaysia about a decade ago. Amongst the major issues that arose, was the absence or lack of digital geospatial data. GIS users then, needed to digitize their own data from hardcopy maps or survey plans to convert them to digital data. This conversion was certainly time-consuming and expensive, so much so, that accuracy of data was not of paramount importance. At present, with the realization of …
Latest Indian RS Satellite Cartosat-2B and a Dream’ of students
India’s Polar Satellite Launch Vehicle (PSLV-C15) successfully launched CARTOSAT-2B from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota on 12 July 2010.
In addition to CARTOSAT-2B; PSLV-C15 carried four auxiliary satellites namely STUDSAT a pico-satellite weighing less than 1 kg, built jointly by students from a consortium …
says Shri KR Sridhara Murthi, Managing Director, Antrix Corporation with reference to the Indian Remote Sensing Satellite.
What are the added features in CARTOSAT-2B as compared to CARTOSAT-2A? What will be its marketing strategy?
CARTOSAT-2B is an identical satellite of CARTOSAT-2A and is meant for continuity of services. They are not available for commercial distribution. As …
