Kalpana-1 (formerly METSAT-1 , which stands for Met eorological Sat ellite) is an Indian geostationary weather satellite operated by the Indian Space Agency , ISRO .

task

Kalpana-1 is the first exclusive weather satellite built by ISRO. So far, meteorological services have been combined with telecommunications and television services in the Insat system. The satellite will be a precursor to the future Insat program.

construction

Kalpana-1 was developed by the ISRO Satellite Center in Bangalore . The meteorological payloads were developed by the Space Applications Center.

For earth observations, Kalpana-1 has a very high-resolution radiometer that maps the earth in the thermal infrared and water vapor range . It also carries a data relay transponder for collecting data.

At the time of launch, Kalpana-1 weighed 1055 kg, of which about 560 kg was fuel. The propellant carried by Kalpana-1 is mainly required to raise the satellite from geostationary transfer orbit to its final geostationary orbit .

A new spacecraft bus with lightweight structural elements was used at Kalpana-1. The satellite has a solar system with an output of 550 watts. A solar panel attached to the side collects the electricity .

begin

Kalpana-1 was on 12 September 2002 aboard a PSLV - carrier rocket from the Satish Dhawan Space Center under the name METSAT-1 into a geo-transfer orbit started.

The solar panel was automatically deployed immediately after it was injected into the GTO. In the days after launch, METSAT-1's orbit was raised from its elliptical park orbit to its final geostationary orbit by firing the satellite's liquid apogee motor multiple times. The satellite was put into operation after completion of the orbitalization and stationed at the position 74 °.

renaming

On February 5, 2003, METSAT-1 was renamed Kalpana -1 by ISRO in honor of the American, Indian-born astronaut Kalpana Chawla , who died in the accident flight of the Columbia space shuttle on February 1, 2003.
