The Indian Space Research Organization will launch 13 commercial nano satellites of the United States along with the imaging and mapping satellite Cartostat-3. The launch is scheduled on November 25, 2019.
The satellites will be launched by PSLV-C47, a Polar Satellite Launch Vehicle into Sun Synchronous Orbit from Satish Dhawan Space Centre at Sriharikota.
Cartosat-3 is the third generation Earth observation satellite built by ISRO. It is one of the most advanced imaging satellites built by the organization so far. It has the capability to produce high resolution aerial images in the world. The features of the satellite include
- Panchromatic-Captures all visible colors of light
- Hyperspectral-Captures light from electromagnetic spectrum
- Multispectral-Captures light within specific ranges of the electromagnetic spectrum.
Till date, eight Cartosats have been launched.
13 commercial satellites
The 13 satellites are launched by the Luxembourg based space company Kleos, as a part of its multi-satellite constellation mission called the Scouting Mission. The Scouting mission aims to provide a global picture of unregistered marine activity and surveillance and intelligence capability to government and commercial entities. The mission also has an Automatic Identification system that rectifies commonly faced challenges of the surveillance mission.

In next 2 months, ISRO will launch 14 small foreign satellites in its next three PSLVs (Polar Satellite Launch Vehicles). The projects are to be implemented by November and December.
- The payloads are to be launched in three PSLV flights namely PSLV-C47, PSLV-C48, PSLV-C49.
- The Indian payload Cartosat-3 will be the primary payload of PSLV-C47. The Cartosat satellites are a series of Indian earth observatory satellites built and operated by ISRO. The Cartosat-3 is a remote sensing satellite.
- So far ISRO has launched 300 small satellites to low earth orbits for foreign customers.
The small satellites weigh around 500 kg. These satellites reduce large economic costs of launch vehicles. They are of lower cost, more frequent, quicker and offer broader access to space. They are primarily used for communication, research, meteorology and insurance.
The small satellites are mini-satellites, micro-satellites and nano-satellites.
The INS-ISRO Nano Satellites have capability to carry up to 3 kg. The primary objective of the INS is to provide an opportunity to carry payloads for universities and R&D laboratories. They also provide an opportunity for ISRO technology demonstration payloads.
