Resourcesat-1 (IRS-P6) satellite data

The Geoscience Australia objectives with the Resourcesat-1 (IRS-P6 mission) are to provide continued remote sensing data services on an operational basis for integrated land and water resources management. IRS-P6 is the continuation of the IRS-1C/1D missions. The launch of the satellite took place October 17, 2003.

Resourcesat-1 is also known as IRS-P6. IRS-P6 is an Earth observation mission within the Indian Remote-Sensing (IRS) series of satellites operated by the Indian Space Research Organisation (ISRO), Bangalore, India.

ACRES commenced acquisition of Resourcesat-1 Linear Imaging and Self Scanning sensor (LISS-III) and Advanced Wide Field Sensor (AWiFS) data in February 2008, although distribution of Resourcesat-1 data by ACRES is not yet operational.

The data will be routinely recorded over Australia, although not every pass will be acquired and archived.

Archive data over Australia will be available to Australian and New Zealand residents only. For more information on the availability of Resourcesat-1 data contact ACRES.

About Resourcesat-1 (IRS-P6)

The satellite has three sensors on-board: a LISS-III sensor, AWiFS sensor and a high resolution multi-spectral Linear Imaging Self-Scanning Sensor-4 (LISS-IV) along with an On-Board Solid State Recorder (OBSSR).

All sensors work on the 'pushbroom scanning' concept using linear arrays of Charge Coupled Devices (CCDs). In this mode of operation, each line of image is electronically scanned and contiguous lines are imaged by the forward motion of the satellite. Below image for Nadir viewing only.

Only LISS-III and AWiFS data are acquired and distributed by ACRES.

The LISS-III and AWiFS sensors operate in four spectral bands, three in the visible and near infrared and one in the SWIR (1.55 to 1.7 microns) region.

The LISS-III sensor has radiometric quantisation of 7 bits and provides a combined swath of 141 kilometres with a spatial resolution of 23.5 metres.

The AWiFS sensor has radiometric quantisation of 10 bits and provides a combined swath of 740 kilometres with a spatial resolution of 56 metres at nadir.

All sensors have the feature of on-board detector calibration using LEDs. The sensors can be operated either in Real Time mode by direct transmission to ground station or in Record and Playback mode using an on-board 120 GB capacity Solid State Recorder.
