The 23rd mission of PSLV-C20 has been successfully launched. This is the ninth time ISRO is using the 'core alone' variant of the rocket.
The 668.5 kgs and 44.4 metres tall rocket had a lift off mass of 229.7 tonnes. Besides 'SARAL', it put into orbit two micro-satellites UniBRITE and BRITE from Austria and AAUSAT3 from Denmark and STRaND from United Kingdom and also one micro-satellite (NEOSSat) and one mini-satellite (SAPPHIRE) from Canada.
The ISRO-built SARAL is a 410-kg satellite with payloads - Argos and Altika - from French space agency CNES for study of ocean parameters towards enhancing the understanding of the ocean state conditions which are otherwise not covered by the in-situ measurements.
SARAL will provide data products to operational and research user communities, in support of marine meteorology and sea state forecasting; operational oceanography; seasonal forecasting; climate monitoring; ocean, earth system and climate research.Altimeter (Altika) would help study the sea surface heights while Argos payload is a satellite-based data collection platform.
