Masood M. Sharif Mahmood, CEO, Yahsat said: “Yahsat continues to invest in YahClick and its commercial business. To date, the company has spent well over USD 400 million in Capex and Opex and has taken on Al Yah 3, a program with an additional investment of around USD 400 million, demonstrating commitment to and confidence in our business goals. In line with our aggressive roadmap for success, we are fully committed in executing the right strategies to ensure we both reap the maximum rewards from these investments.”
--------------------
The CEO confirmed that Yahsat’s third satellite Al Yah 3 is on track for launch in the fourth quarter of 2016. Al Yah 3, built by Orbital Sciences Corporation and operating solely in the Ka-band, will provide broadband internet services at affordable prices to nearly 600 million users in Brazil and Africa. It offers a design life of 15 years.

Abu Dhabi, UAE December 12, 2014 – Yahsat, the UAE-based satellite operator, a wholly owned company of the Mubadala Development Company, and Orbital Sciences Corporation [NYSE: ORB] today announced that they have completed the Preliminary Design Review (PDR) for the Al Yah 3 spacecraft and payload. Al Yah 3, which is based on Orbital’s GEOStar-3™ platform, is an all Ka High Throughput Satellite to be designed, manufactured and tested at Orbital’s satellite manufacturing facility in Dulles, VA.

The PDR was a comprehensive review that validated Orbital's design approach to the physical and functional requirements of the spacecraft. The review is the first step toward confirming that the satellite will operate effectively on orbit.

Masood M. Sharif Mahmood, Chief Executive Officer at Yahsat said, “The Preliminary Design Review is an industry standard process where our engineers review and confirm the overall architecture and design of our Al Yah 3 satellite. This is a significant step forward in the development phase of Al Yah 3 and ensures that we are on track to launch as scheduled for Q4 2016. While progress is underway with developing our third satellite, we are actively engaging with potential partners in Africa and Brazil enabling us to deploy much needed connectivity to underserved markets.”

Once operational, Al Yah 3 will enable the delivery of affordable broadband, to over 600 million users, specifically covering more than 95% of the population in Brazil and 60% of the population in Africa.

“This important milestone is a key step towards the Al Yah 3 launch”, said Mr. Christopher Richmond, Orbital’s Senior Vice President. “Al Yah 3 will be the first hybrid electric propulsion GEOStar-3-based spacecraft to be launched by Orbital at the end of 2016. It provides the benefits of higher power and greater payload capability while still maintaining advantageous launch costs.”

Yahsat, Orbital ATK, Masdar Institute Create Space Systems and Technology Master’s Degree Programhttp://www.satellitetoday.com/technology/2015/05/27/yahsat-orbital-atk-masdar-institute-create-space-systems-and-technology-masters-degree-program/

The preexisting Yahsat-Orbital ATK partnership helped guide the academic program’s development and adds a greater technical dimension. Orbital ATK is building the operator’s next satellite, Al Yah 3, which is slated to launch aboard Arianespace’s Ariane 5 ECA rocket in 2016.

Al Yah 3, Yahsat’s third satellite, is scheduled to launch in 2017 with Arianespace and expands the operator’s coverage into the Brazilian market. Yahsat has two geographically separated gateways for the satellite to counter outages due to heavy rain or ensure continuity during scheduled or unscheduled maintenance. Orbital ATK is building the satellite, which will provide coverage to more than 95 percent of the Brazilian population.

美国NASA首次通过商业卫星研究太空天气
0
cnBeta.COM   2018-01-16
[size=1em]摘要:
在本月底,美国宇航局将进行一次太空任务,以便更好地了解高能粒子和地球大气上层的空间天气。而且这次研究首次依靠一颗商业卫星上的科学仪器进行。

这颗名为SES-14的商业卫星将于一月底借助欧洲阿丽亚娜5号火箭发射,SES-14将最终爬升到地球表面上方约22000英里高的轨道,然后这颗卫星上名为GOLD的仪器将收集有关地球上层大气和太空之间的边界数据,这是一个30到600英里之间的地区,即电离层,这也是可能发生重大空间天气事件的地方。
GOLD收集的数据将帮助科学家更好地预测电离层如何对某些类型的自然现象或事件做出反应,例如海浪,海啸或飓风。另外,NASA将在今年晚些时候发射一颗卫星,进行另一个名为ICON的NASA任务,该卫星将坐落在一个低得多的轨道上,在那里它可以收集关于电离层的更多近距离数据。
GOLD研究的最大事情之一是太阳如何与电离层相互作用。例如,太阳产生了很多极端的紫外线辐射,然后被我们星球周围的气体吸收。这实际上有助于防止人们接受太多有害剂量的辐射。但它也会使电离层中的粒子升温并发出光 - 即所谓的气辉。
太阳也会周期性地向地球喷射一堆能量粒子,这些事件被称为日冕物质抛射,可能会导致对地球磁场干扰。当这样的地磁风暴发生时,电离层中的粒子不仅会升温而得到激励,而且会向上移动并扩张,改变高层大气的密度。
这些事件可能会对我们在这里产生重大影响,因为电离层已经成为我们日常生活中许多技术使用的关键地方,包括各种GPS和通信卫星以及国际空间站,用于与船舶和飞机通信的无线电信号以及与地球电网相互作用的电流。然而,电离层的大风暴可能会让太空船偏离轨道,堵塞通讯系统,造成电力波动。

喜欢这个5.2米又粗又大的氢氧罐子,不过有点纳闷,怎么起飞推力更大,芯级更粗的阿丽亚娜5的LEO和GTO都比长五小一些?是不是固推拖了点后腿?

当然和助推有关系,不过长征五号起飞质量要重100吨呢,但是虽然长征五号芯级干质比低,二级还超重了,但是长五的gto运载系数还是比阿里安5高,这就是固推与液推的差距,毕竟固推比冲低,燃烧时间短
