Спутник ДЗЗ. SARAL. [Редактировать]

КА SARAL был создан Индийской организации космических исследований ISRO совместно с Французским космическим агентством CNES. Согласно Меморандуму о взаимопонимании, подписанному 23 февраля 2007 года Агентство CNES предоставило:

  • радиолокационный высотомер Altika,
  • прибор определения параметров орбиты DORIS,
  • лазерный уголковый отражатель LRA,
  • систему сбора информации Argos-3 
  • обеспечение приема и обработки информации. 

Организация ISRO предоставила:

  • спутниковую платформу IMS-2; 
  • обеспечила операции запуска РН PSLV, услуги по эксплуатации КА.

На спутнике SARAL используется трехосная система стабилизации, четыре маховика (5 Н-м) тетраэдрической конфигурации и 2 магнитных датчика моментов. Для оптимизации точности определения ориентации КА и обновления данных, поступающих с миниатюрных гироскопов, используются миниатюрный астродатчик, предоставляющий данные с точностью < 30 угловых микросекунд, а также четыре солнечных датчика (поле зрения 4π) и миниатюрный трехосевой магнитометр.   Система телеметрии, слежения и управления передает сигнал в S-диапазоне со скоростью 4 кбит/с с использованием практически всенаправленной антенны, передача данных в направлении спутник-Земля ведется в X-диапазоне со скоростью 32 Мбит/с с использованием профильно-лучевой антенны. Антенна с профилированной диаграммой направленности (ДН) с коэффициентом усиления +4,5 дБи в секторе ±65°, а также полупроводниковый усилитель мощности 4 Вт обеспечивают необходимый энергетический запас. Помимо этого УВЧ-диапазон используется прибором Argos-3 для получения информации с наземных станций, а L-диапазон – для передачи накопленных данных в центры информации.

КА SARAL предназначен для измерения высоты поверхности мирового океана, высоты волн и скорости ветра. Полученные с его помощью данные будут использоваться для расширения знаний в области океанографии, понимания факторов, влияющих на изменение климата, составления прогнозов погоды и в других метеорологических целях. Спутник SARAL позволит исключить перерыв в поступлении данных между окончанием эксплуатации спутника Envisat и началом функционирования спутника Sentinel-3. Поступающая с КА SARAL информация будет дополнять данные, поступающие с КА Jason-2.

Contribution of SARAL/Altika to the Global Mean Sea Level estimation P. Prandi, Y. Faugère, M. Ablain, N. Picot With large contributions from A. Cazenave SARAL/AtiKa Science Workshop -1- Sea Level: a sensitive index for climate change • • • In situ and satellite observations indicate that sea level is currently rising, Models predict sea level will continue to rise in the future decades, But how much ? We don’t know • Coastal impacts of sea level rise are among the most threatening consequences of global warming, • Continous and accurate monitoring of sea level change (globally and regionally) by satellite altimetry is a high priority objective, Such monitoring can’t be achieved without multiple satellite altimetry missions flying at the same time. • SARAL/AtiKa Science Workshop -2- Past, present and future sea level rise SARAL/AtiKa Science Workshop -3- Past and present sea level rise from historical data SARAL/AtiKa Science Workshop -4- Present-day sea level rise from satellite altimetry Rate of sea level rise : 3.3 mm/yr Current uncertainty : 0.6 mm/yr (90%) 6 cm SARAL/AtiKa Science Workshop -5- Regional sea level rise patterns from satellite altimetry • Sea level trends over 1993-2009 from DUACS multi-mission maps, • Data (time series and maps) are available from AVISO (www.aviso.oceanobs.com) SARAL/AtiKa Science Workshop -6- Sea Level Budget SARAL/AtiKa Science Workshop -7- Uncertainties affecting satellite altimetry • Errors affecting satellite altimetry MSL trend calculation (Ablain et al., 2009) : Orbits 0.10 mm/yr 0.15 mm/yr Wet tropo 0.20 mm/yr 0.30 mm/yr DAC and dry tropo 0.05 mm/yr 0.10 mm/yr Sigma0 drift 0.05 mm/yr 0.10 mm/yr Mission bias 0.10 mm/yr 0.25 mm/yr Total 0.6 mm/yr (90%) • Uncertainties assessed by CAL/VAL activities are low enough for climate studies, • MSL drift evaluated from tide gauge data for T/P and Jason-1 is 0.3 mm/yr, within the ±0.6 mm/yr interval • => reliability of T/P+Jason GMSL trend SARAL/AtiKa Science Workshop -8- Interest of SARAL/Altika for global sea level rise monitoring • No such accurate long-term monitoring is achievable with only one satellite altimeter : – CAL/VAL activities – Drift detection and correction – Uncertainty evaluation See Y. Faugère’s talk • With the possible end of Envisat and Jason-1, • With issues regarding CryoSat-2 data over oceans, • Another satellite altimetry system is crucial to increase the global mean sea level record, • SARAL/Altika will provide complementary data to Jason-2 allowing to keep track of mean sea level rise SARAL/AtiKa Science Workshop -9- Regional sea level studies • Regional MSL is important to evaluate local impacts, • Multiple satellites are important to combine : • Temporal sampling (Jason like) • Spatial sampling (Envisat like) • At regional scales, altimetry MSL error budget is higher due to geographically correlated errors, • An example on T/P – Jason 1 bias -2 -3 mm/yr cm SARAL/AtiKa Science Workshop - 10 - + -3 2 The high latitudes issue : Arctic Ocean • Arctic climate is changing quickly and dramatically: • Sea ice loss, • Temperature rise for both atmosphere and ocean, • Greenland ice sheet melting, • But we hardly know sea level variability, • Only sampled by ERS-1, ERS-2 and Envisat up to 82°N, • Suffers from increased error sources, • Geophysical corrections, • Seasonnaly covered by sea-ice, • From Ssalto/Duacs sea level dataset, Arctic Ocean sampling is needs to be improved, SARAL/AtiKa Science Workshop - 11 - The high latitudes issue : Arctic Ocean • Need for a regional reprocessing of the data, • Performed over 1993-2009 period, • For latitudes between 50°N and 82°N • Tide model and mean sea surface change, • Multi-mission biases recalculated, • Regional high resolution objective analysis, • Achieving an improved sampling af the Arctic Ocean, • Leading to more reliable estimates for regional sea level variability. SARAL/AtiKa Science Workshop - 12 - Conclusions • Global mean sea level is one of the most used indicator for climate change, • Sea level rise impacts are among the most threatening to human activities, • It is crucial to have a continuous and precise mean sea level record, • SARAL/Altika mission will contribute to mean sea level monitoring for climate studies, both global and regional, • Concerning the high latitudes, SARAL/Altika will play a crucial role : • Cross-calibration with Envisat, • Ensure the measurement continuity, threatened by Envisat’s mission end SARAL/AtiKa Science Workshop - 13 - Thank You SARAL/AtiKa Science Workshop - 14 -
