阿根廷Satellogic公司的ÑuSat-1/ÑuSat-2在2016年5月30日11:17搭载长征四号乙火箭从太原发射升空




2016年5月26日上午,阿根廷Satellogic公司项目经理阿岚·卡桑斯基(Alan Kharsansky)一行到航天东方红进行参观访问,了解公司相关AIT设施。

   

      Satellogic一行着重参观了航天东方红的总装和振动试验等设施,了解了小卫星生产的各项流程,对公司所取得的重要成果表示赞叹。双方探讨了小卫星生产未来的发展趋势,认为如何实现流水线式的标准化生产、降低卫星生产成本是目前众多卫星公司面临的共同挑战。此外,双方也就小卫星制造在流程和硬件设施上的差异及小卫星星座的有关事项进行了交流,对后续合作可能进行了探讨。

  Satellogic是一家卫星初创公司,其目标是以传统模式千分之一的成本打造微小卫星星座,利用最新的纳米卫星技术获取高分辨率、实时的卫星影像和数据。据悉,目前Satellogic公司正致力于打造一个包含低地球轨道运行的300颗卫星的星座,构成一个覆盖整个地球的实时数据流,每隔几分钟就能获取地球任何一个地点的影像,真正实现 “卫星网络”。

        此次来访使Satellogic公司对航天东方红的生产水平和实力有了更加直观的了解,为国际市场的开发和今后在小卫星星座的合作奠定了基础。

**The above frequencies have now been coordinated and the launch date is now expected to be May 30th 2016**


头两颗从4月30日推迟到5月30日,今年的另外4颗由俄罗斯第聂伯火箭发射。

计划在2017年上半年发射完成16颗卫星。

Satellogic originally planned to begin launching its satellites in 2015, so that a service constellation of 16 spacecraft would be active this year, but launch delays have stretched out this timeline. Kargieman said the company now plans to have an initial constellation of six satellites by year’s end, with two launching May 30 on a Long March 4B from China, and another four later on aboard a Russian Dnepr rocket.


ÑuSat-1 and ÑuSat-2 :Two identical 37kg, 450mm x 450mm x 800mm, spacecraft. 

         The primary objective of the mission is to commercially provide earth observation images to the general public, in the visible and infrared parts of the spectrum. 

         Additionally, the satellites will carry a U/V linear transponder provided by AMSAT-LU to offer services to the HAM community.In addition to opertaion in other services with downlinks on 8GHz and uplinks on 2GHz, the group is proposing a U/V transponder which will ahve a 100kHz bandwidth with an output power of 2 watts. 

       An additional backup telemetry downlink on UHF operating at >9k6 GFSK is also proposed. 

      Planning a launch from Taiyuan Satellite Launch Center. Taiyuan, China on 30th April 2016 into 500km SSO 97.5 degree orbit with a 10:30 LTAN.** More information has been reqeusted from the group**


      Satellogic is facing currently building a constellation of satellites and earth observation Amsat- LU invited to participate in the project of the next two satellites, ÑUSAT ÑUSAT 1 and 2 in one riding an analog linear transponder amateur radio and its corresponding antenna.

      This time, the experiment AMSAT LU - still has no proper name - is smaller in size and mounted on a radiating plate 10 x 10 cm, in which the required components are also soldered to the power supply and duplexer. The set will be installed on the bus Ñusat, which provide energy and be part of several other experiments that carried this satellite.

       The transponder receives UHF and VHF broadcasts, has a bandwidth of 30 kHz and output power is 200 mW. 

Uplink frequency 435 935 ~ 965 LSB / CW,

Downlink frequencies 145 965 ~ 935 USB / CW.

Basic CW telemetry 145,900.


头两颗的运载工具是CZ-4B


阿根廷卫星初创公司Satellogic的创始人Emiliano Kargieman在北京表示,2016年4月,他们将使用中国的长征火箭,将16颗卫星运载到太空;未来一段时间内,将增加到 300 颗卫星,真正实现 “卫星网络”,对地球进行实时的监测。
