In the second orbit raising manoeuvre, conducted at 12 noon (IST) today (April
12, 2003), the 440 Newton Liquid Apogee Motor (LAM) on board INSAT-3A was fired
for 53 minutes by commanding the satellite from Master Control Facility (MCF),
Hassan. With this LAM firing, INSAT-3A perigee (closest point to the earth) has
been raised from 11,500 km to 32,750 km. The apogee is 36,000 km and the
inclination of the orbit with respect to the equatorial plane has been reduced
from 0.9 deg to the present 0.1 deg. INSAT-3A now has an orbital period of 22
hour, 40 minutes. The satellite will now be in the continuous radio visibility
of MCF-Hassan.
INSAT-3A was launched by Ariane-5 of Arianespace on April 10, 2003 from Kourou,
French Guyana, and the first orbit raising manoeuvre was carried out from
MCF-Hassan yesterday (April 11, 2003). The satellite came within the radio
visibility of MCF this morning at 5:50 a.m. (IST), and all the necessary
operations like earth acquisition and gyro calibration were carried out before
the second orbit raising manoeuvre was started.All systems on board INSAT-3A
are functioning normally. Third apogee raising manoeuvre is planned on April
14, 2003.
