Timeline to over 40 years of historical satellite missions

ESA's Heritage Space Programme preserves historical data from over 40 years of Earth observation missions.

ESA and GAF AG continue to offer free-of-charge access to Third Party Mission data

In January 2021, ESA and GAF AG extended their agreement under ESA’s Third Party Missions programme regarding the provision of IRS data and DSMs until the end of 2021.

A stroll through Heritage Missions

At ESA's Earth Observation centre—ESRIN—in Frascati, Italy, there is a place where one can walk back in time, to better understand the history and importance of Heritage Missions and their data.

About IRS-P6

IRS-P6 (also known as ResourceSat-1) launched on 17 October 2003 from Satish Dhawan Space Centre by the Indian PSLV-C5, and came to an end on 30 September 2013. The mission was part of the IRS (Indian Remote-Sensing Satellite) series of ISRO (Indian Space Research Organization).

Prior to launch, ISRO renamed the IRS-P6 spacecraft to ResourceSat-1.

*Mission Parameters*
Launch Date	17 October 2003
Mission Status	Ended 30 September 2013
Orbit Height	820 km
Orbit Type	Polar sun-synchronous
Revisit Period	24 days

ResourceSat-1 is part of ESA's Third Party Missions Programme, in which ESA has an agreement with ISRO to distribute data products from the missions.

IRS-P6 Objectives

The overall objectives of the IRS-P6 mission (ResourceSat-1) was to provide continued remote sensing data services on an operational basis for integrated land and water resources management. The mission provided data continuity for the IRS-1C and IRS-1D satellites, with the addition of new instruments.

IRS-P6 Instruments

ResourceSat-1 carried three instruments:

A high resolution linear imaging self-scanner (LISS-IV)
A medium resolution linear imaging self-scanner (LISS-III)
AwiFS (Advanced Wide Field Sensor)

All three cameras were pushbroom scanners using linear arrays of CCDs (Charge Coupled Devices).

DATA DESCRIPTION

ESA is offering, for scientific research and application development, access to Full archive of ResourceSat-1 data upon submission and acceptance of a project proposal. These products are available as part of the GAF Indian Satellite Imagery products.

ESA will support as many high-quality and innovative projects as possible within the quota limit available, therefore only a limited amount of products can be made available to each project.

The following collection is available:
