INSAT-4CR Raised To A Perigee Of 15994 Kilometers
Bangalore (PTI) Sep 06, 2007 INSAT-4CR, India's communication satellite successfully launched on Sunday, was today raised to a perigree of 15,994 kms as planned in the third of its orbit raising manoeuvres. The operation was conducted at 4.35 am with the firing of the 440 Newton Liquid Apogee Motor (LAM) on board for 3140 seconds by commanding the satellite from the Master Control Facility at Hassan in Karnataka, a release said here today. With this LAM operation, INSAT-4CR perigree has been raised to 15,994 kms, the release said. The apogee is at 35,385 km and the inclination of the orbit with respect to the equatorial plane has been reduced from 11.1 deg to 3.24 deg now, it said adding the orbital parameters achieved are as planned. The present orbital period is 15 hours 52 minutes. INSAT-4CR was successfully launched by GSLV-F04 on September two from Satish Dhawan Space Centre, SHAR, Sriharikota. Subsequently, the Master Control Facility had acquired the signals from the satellite and conducted initial phase operations on INSAT-4CR. All systems on board the satellite are functioning normally. The next orbit raising manoeuvre is planned around 12.30 pm tomorrow, it said. INSAT- 4CR is the third in the INSAT 4 series and is expected to boost DTH television services, digital news gathering services and other high bit rate data transmission in the country.

ISRO scientists leave for better pay While in 2006, 187 out of 354 scientists/engineers recruited left ISRO, the corresponding figures for 2004 and 2005 were 105 out of 360 and 100 out of 346, Minister of State in the PMO Prithviraj Chavan said in a written reply in the Lok Sabha. "Stupendous growth of Information Technology and Communication sectors in the country and the high remunerative packages being offered by the private sector are the main reasons for the scientists/engineers to leave ISRO," he said. Chavan said a host of steps were being taken to encourage and motivate students in schools and colleges to join space studies and space research like providing opportunity for visits to ISRO centres, organisation of open house discussions and exhibitions every year. The department of space has submitted a proposal to the VIth pay commission for enhanced pay and special incentives as performance based annual increments, he said.
