TELEOS-2 SATELLITE

The Indian Space Research Organisation (ISRO) will launch Singapore’s TeLEOS-2 satellite.
The launch will be carried out by the Polar Satellite Launch Vehicle (PSLV.
TeLEOS-2 is an Earth Observation Satellite.
In 2015, ISRO launched TeLEOS-1, the first Singapore commercial Earth Observation Satellite.

More about the satellite:

TeLEOS 2 is a Singaporean SAR Earth Observation satellite.
It is built by ST Electronics (Satellite Systems).
The satellite is built on a bus based on the TeLEOS 1 optical earth observation satellite and is to operate in conjunction with this satellite.
TeLEOS 2 carries a made-in-Singapore Synthetic Aperture Radar (SAR) payload capable of providing 1 m resolution data.
It will be equipped with a 500 Giga Bytes onboard recorder for recording the data captured and a high speed 800 Mbps down link.

Earth Observation Satellites

An Earth observation satellite also called Earth remote sensing satellite is a satellite designed for Earth observation (EO) from orbit.

Applications:

1. Weather

2. Environmental monitoring

3. Mapping

Geostationary orbit:

· A geostationary orbit allows a satellite to hover over a constant spot on the earth.

· The orbital period at this altitude is 24 hours.

· This allows uninterrupted coverage of more than 1/3 of the Earth per satellite.

· Three satellites, spaced 120° apart, can cover the whole Earth except the extreme polar regions.

· This type of orbit is mainly used for meteorological satellites.
