What is SARAL?

techsmartworld.com

Saral [Satellite with ARGOS and ALTIKA (SARAL)] is an Indo-French joint expedition for oceanographic studies. Designed for altitude measurement for simple ocean transmission and ocean surface elevation studies.

Saral has the following payloads: -

K-band TungtaMapi, Altica - It is designed by the French National Space Agency CNES. The payload, intended for oceanographic applications, operates at 35.75 GHz.

ARGOS (ARGOS) data collection system - This payload created by French National Space Agency CNES will contribute to the development and executive implementation of the global ARGOS data collection system. This payload will receive data from marine excavators (Voya) and disseminate them to the Argos Geosynchronous System for subsequent processing and distribution. This will be useful in providing direction to the sailors.

SolidSat C-band transponder (SCBT) - It is designed for radar geo-calibration by ISRO. This will help maintain the continuity of the C-band transponders on the earlier IRS-P2 and IRS-P5.

Saral's payloads are installed on the ISRO-built Indian Mini Satellite'2 bases.
