12-11-2013	Fourth supplementary orbit raising manoeuvre of Mars Orbiter Spacecraft, starting at 05:03:50 hrs(IST) on Nov 12, 2013, with a burn Time of 303.8 seconds has been successfully completed. The observed change in Apogee is from 78276km to 118642km.
11-11-2013	In the fourth orbit-raising operation conducted this morning (Nov 11, 2013), the apogee (farthest point to Earth) of Mars Orbiter Spacecraft was raised from 71,623 km to 78,276 km by imparting an incremental velocity of 35 metres/second (as against 130 metres/second originally planned to raise apogee to about 100,000 [1 lakh] km). The spacecraft is in normal health.
09-11-2013	The third orbit raising manoeuvre of Mars Orbiter Spacecraft, starting at 02:10:43 hrs(IST) on Nov 09, 2013, with a burn time of 707 seconds has been successfully completed. The observed change in Apogee is from 40186km to 71636km.
08-11-2013	The second orbit raising manoeuvre of Mars Orbiter Spacecraft, starting at 02:18:51 hrs(IST) on Nov 08, 2013, with a burn time of 570.6 seconds has been successfully completed. The observed change in Apogee is from 28814 km to 40186 km.
07-11-2013	The first orbit raising manoeuvre of Mars Orbiter Spacecraft, starting at 01:17 hrs(IST) on Nov 07, 2013 has been successfully completed.

IRNSS Signal-in-Space(SIS) Interface Control Document (ICD) released for public (ISRO)

Indian Regional Navigation Satellite System (IRNSS) IRNSS is an independent regional navigation satellite system being developed by India. It is designed to provide accurate position information service to users in India as well as the region extending up to 1500 km from its boundary, which is its primary service area. IRNSS will provide two types of services, namely, Standard Positioning Service (SPS) and Restricted Service (RS) and is expected to provide a position accuracy of better than 20 m in the primary service area. The IRNSS Signal-in-Space Interface Control Document (ICD) for Standard Positioing Service (SPS) is released to the public to provide the essential information on the IRNSS signal-in-space, to facilitate research & development and aid the commercial use of the IRNSS signals for navigation-based applications. Launch Date 04.04.2014  IRNSS-1B is the second dedicated navigation satellite of India.  Launch Date 01.07.2013  IRNSS-1A, the first of the seven satellites of the IRNSS constellation, launched onboard PSLV-C22. GPS Aided GEO Augmented Navigation (GAGAN) GAGAN is a Satellite Based Augmentation System (SBAS) implemented jointly with Airport Authority of India (AAI). The main objectives of GAGAN are to provide Satellite-based Navigation services with accuracy and integrity required for civil aviation applications and to provide better Air Traffic Management over Indian Airspace. The system will be interoperable with other international SBAS systems and provide seamless navigation across regional boundaries. The first GAGAN navigation payload was flown on GSAT-8 which was launched on May 21, 2011 and the second on GSAT-10 launched on Sep 29, 2012.

Latest NEWS of Microsoft .NET

Sela and Microsoft have established a wonderful tradition: several times a year, VP-level R&D managers from various Israeli companies meet at the Crowne Plaza hotel (with beautiful views to the Tel-Aviv beach) to share news and hear updates about Microsoft technology.

The latest meeting was yesterday, and I had the opportunity to present a 45-minute talk covering the latest announcements from Build 2013 and some of the more recent news concerning Visual Studio 2013, Windows 8.1, and Windows Azure. Thank you for coming, and I'm looking forward to seeing you at future forum events. My slides are below, and should give you some highlights and pointers to follow later.

Microsoft .Net

Microsoft.NET Framework is one of the most comprehensive as well as consistent model of programming that is primarily used for setting up various applications that are visually seamless with the capacity to set up wide variety of business processes. The present Microsoft.NET Framework version 4 will provide the client a much improved CLR or Common Language Runtime and BCL or Base Class Library, improved access and modeling of vital data, improvement of ASP.NET, and enhancement of WPF or Windows Presentation Foundation, WWF or Windows Work Flow and WCF or Windows Communication Foundation. 

Microsoft .Net Framework software framework can be installed on the Microsoft windows OS. The class library of MS .Net Framework provide a wide gambit of developing features that includes UI or user interface, various numeric algorithms, development framework of web application, development of desktop and network application, database connectivity as well as cryptography. The MS.NET Framework that are used by our .Net Developers and ASP net programmers help in creating their own codes & develop new applications. The .Net Framework supports carious server technologies along with the client technologies that include ASP .Net (ASP - active server page), Windows forms forth windows desktop solutions and a compact framework for various PDA & Mobile solutions.
