希望二号A-F小卫星

希望二号卫星顺利通过在轨寿命考核

时间:2016-05-03 信息来源:中国空间技术研究院

      去年9月20日,希望二号卫星由CZ-6运载火箭以一箭20星方式发射入轨。入轨后卫星进行了多项试验,获取了大量科学试验数据,圆满完成了既定任务。截止到今年3月20日,顺利通过了六个月在轨寿命考核,目前卫星稳定运行。

希望二号卫星系统由1颗20kg级纳星、3颗10kg级皮星及2颗1kg级子星组成。卫星采用标准化、模块化设计,使用COTS器件及其防护措施的设计理念,形成应用型皮纳卫星产品系列。

       作为航天东方红自主研发的皮纳卫星系列的首发星,希望二号卫星在轨稳定运行,为我院应用型皮纳卫星的后续发展与微小型产品型谱化奠定了坚实基础。卫星后续还将持续进行平台和载荷的在轨拓展试验和验证,并进行平台长期在轨可靠性考核,为用户提供持续、优良的服务与支持。


长春SLR站国际首次成功观测到PN-1A卫星

          2015年11月11日九点零八分,我站在国际上首次成功观测到最新加入到ILRS国际联测的PN-1A卫星,数据处理后的时间偏差为162.2ms、距离偏差为23.0m。该卫星轨道高度低(450-120km)、运行速度快、预报偏差较大、我站在第一时间对该卫星的成功测距充分体现了对预报精度差卫星具有有效的观测方法及卫星激光测距系统具有较高的测距能力。图1和图2为PN-1A卫星的数据处理界面图。

        PN-1A卫星于2015年9月19日发射,是APOD(大气密度检测和精密定轨)实验卫星中的一颗,该卫星的轨道高度随着时间的推移从450km-120km逐渐降低、轨道倾角为97.47度、为近圆形轨道。APOD实验卫星是中国的一项倡议项目,旨在精密定轨和热层密度的探测,包括1个15公斤重的纳米卫星(PN-1A),和3个相同重5公斤的皮卫星(PN-1B,-1C,-1D),上面载有GNSS接收机、SLR反射器及VLBI信标及大气密度探测器。

Headline Details: 

CAMSAT is working closely with DFH Satellite Co. Ltd which is Chinese governmental aerospace contractor to build six satellites and all involved in amateur radio. A U/V mode linear transponder, a two meters CW telemetry beacon and an AX.25 19.2k, 9.6k and 4.8k baud GMSK telemetry downlink will be attached in each of the six satellites, each set of amateur radio equipment will have the same technical characteristics, but operates on different frequencies of 70cm band uplink and 2m band downlink. In addition, CAMSAT is also assisting other three agencies to complete another three satellites. 


The nine satellites are described: 

CAS-3A: A micro-satellite for atmospheric physics experiments and amateur radio missions. Planned to be 398x398x398mm dimension regular square shape and approx. 25kg mass with three-axis stabilization system. Two daughter satellites CAS-3E and CAS-3F will be piggybacked on top of the satellite. 

CAS3A-1024x482.jpg

CAS-3B, CAS-3C and CAS-3D: Three identical micro-satellites for atmospheric physics experiments and amateur radio missions. each satellite will be 246x246x246mm dimension regular square shape and approx. 10kg mass with three-axis stabilization system. 

CAS3B-1024x482.jpg

CAS-3E and CAS-3F: Two identical Cubesats for amateur radio mission only. Planned to be 116x116x116mm dimension regular square shape and approx. 1.5kg mass. They will be piggybacked on CAS-3A satellite and separated after CAS-3A gets into orbit.
