About Proba-3

Proba-3 is ESA’s – and the world’s – first precision formation flying mission. A pair of satellites will fly together maintaining a fixed configuration as a ‘large rigid structure’ in space to prove formation flying technologies and rendezvous experiments.

Overview

Destination: Elliptical Orbit
Mission: Technology

Elliptical Orbit Satish Dhawan Space Centre First Launch Pad Satish Dhawan Space Centre, India

Proba-3 (Project for On-Board Autonomy 3) is the first close formation flying mission for the European Space Agency (ESA). It consists of two independent, three-axis stabilised spacecraft flying 150 meters from one another with the ability to accurately control the attitude and separation of the two craft. Such formation flying will be maintained for 6 hours, creating ″artificial solar eclipse″ for the satellite below. The spacecraft pair will fly a highly elliptical orbit divided between periods of accurate formation flying around apogee, when payload operations will be possible, and periods of free flight.

PSLV-XL

Family:
Configuration: XL

PSLV-XL is the upgraded version of Polar Satellite Launch Vehicle in its standard configuration boosted by more powerful, stretched strap-on boosters with 12 tonne propellant load. Weighing 320t at lift-off, the vehicle uses larger strap-on motors (PSOM-XL or S12) to achieve higher payload capability. On 29 December 2005, ISRO successfully tested the improved version of strap-on booster for the PSLV. The first use of PSLV-XL was the launch of Chandrayaan-1 by PSLV C11. The payload capability for this variant is 1,800 kg to SSO.
