• The development of operational oceanography (study of mesoscale ocean viability, coastal region observations, inland waters, marine ecosystems, etc. ) The launcher interface uses a Merman clamp band, 937VB. In the nominal mode, the radiometer receivers measure the antenna temperatures (RM1 to RM5). The associated kinetic energy is at least an order of magnitude larger than that of the mean circulation. • Feb. 2015: The SARAL spacecraft is fully operational and carefully controlled by the ISRO team.

Hence, the PRF has been doubled with respect to the Ku-band (Poseidon) instruments. and gives a more accurate measurement of the backscatter coefficient over calm or moderate seas, thus leading to a noise reduction of a factor of two compared to Jason-class altimeters for wave heights greater than 1 m. Moreover, the specificities of the Ka-band backscatter coefficient offer unique contributions in fields that where not foreseen (snow/ice morphology and its temporal variability. SSH differences at crossovers is the main metric to assess the overall performance of satellite altimetry missions. A drawback of the Ka-band is the attenuation due to water/water vapor in case of rain and the resulting loss of data. The combination of two altimetry missions in orbit has a considerable impact on the reconstruction of SSH (Sea Surface Height), reducing the mean mapping error by a factor of 4. IMS-2 is also designed to accommodate different types of payloads with minor modification from mission to mission. SARAL (Satellite with ARgos and ALtiKa) ... To do so, missing measurements are monitored toward the reference ground track (i.e.

Over the ocean, the data coverage is greater than 99.5%, which, once again, exceeds the mission requirements. 2) The second one is considered for a microsatellite series with a total launch mass of around 100 kg, including a payload mass of 20-30 kg All links, both up and down, are encrypted to prevent unauthorized access to the data.

Aluminum honey comb sandwich structure with 4 vertical panels and 2 horizontal decks Sensitivity: (including antenna reflector contribution) - In summary, the SARAL/AltiKa altimeter the first oceanographic altimeter to use a high single frequency in Ka-band (35.75 GHz). Nowadays, the SARAL/AltiKa Ka-band altimetric mission has taken a full position in the altimetric satellite constellation that has been built over years providing a major push to oceanographic sciences. A little less than five years after launch, the satellite and the instruments onboard are performing well although the control of the reaction wheels appeared to be impossible at some stage, end of 2015 and beginning of 2016, leading the leave of the exact 35 repeat orbit and a shift to the Drifting Orbit Phase.

• Production of the mission preliminary and precise orbits is realized by CNES, from DORIS system data, completed by the laser system data, for the precise orbit. AltiKa provides a PRF of about 4000 Hz adjustable along the orbit to cope with altitude variations in the surface profile. assuming a full coverage of the satellite data whatever the conditions are). It is now well recognized that the mesoscale processes are a key component of the ocean circulation, shaping the mean currents, controlling the exchanges with the atmosphere and the marine biogeochemistry, and clearly playing a major role in the way the ocean participate to the climatic system. Beyond the expected contributions of this mission and its very good integration into the objectives of the constellation of altimetric satellites, it has become more and more apparent that specific contributions and innovations related to the main specification of SARAL/AltiKa, that is to say the use of the Ka-band, have clearly emerged. The objective is to gather all the (hardware and software) processing functions of the instrument (digital chirp generator, time FFT, altimeter echo processing, radiometer signal processing, instrument interface handling with the platform computer).

Small Satellite Bus/Indian Mini Satellite - 2 Platform It interfaces with the payloads and acquires the data from payloads through LVDS interface.
