望远镜的曝光时间计算器对于远程观测以及不熟悉整个观测系统的观测人员尤为重要,因为它可以帮助观测者制定合理的观测计划。设计并实现了高美古2.4m望远镜系统的曝光时间计算器(exposuretimecalculator,ETC),它可以根据望远镜及其终端设备的参数,通过计算给出待测天体曝光时间的参考值。这为观测者了解现有条件下极限观测能力,设置曝光时间或者是给定星等和曝光时间计算信噪比提供了依据。将ETC计算结果与实际测光标准星的数据进行了比较,结果表明ETC对测光标准星的计算结果是可靠的。 相似文献

利用怀柔三通道太阳磁场望远镜对太阳进行多层次同步观测可以同时获得日面不同层次的活动图像,这对于更好的理解太阳物理有着重要意义.本文基于怀柔三通道太阳磁场望远镜开发了在局域网内能够对三通道CCD进行同步观测的远程终端观测系统,并通过此系统实现了怀柔基地三通道望远镜和小磁场望远镜的协同观测.系统设计采用vc.net集成开发环境,使用TCP/IP协议,通过套接字网络编程,对三通道太阳望远镜的三个CCD进行同步远程控制,目前系统已经在局域网内实现了图像数据和相机控制命令的传输等远程观测功能,大大降低了观测成本,并取得了初步的观测结果. 相似文献

LAMOST(大型多天体分光望远镜)建成后将成为世界上视场最大、光谱观测效率最高的4m级口径以上的光学望远镜。它将要同时高效地观测4000颗星的光谱,这对网络控制系统的设计是巨大的挑战。该文主要从LAMOST网络控制系统构建的角度介绍了系统如何在大数据量、多任务的情况下实现各子系统控制、环境监测、授时和无线远程监控等功能,叙述了在该系统中运用的实时分布式操作系统、实时数据库,全球定位系统(GPS)和全球移动通讯系统(GSM)等多项技术. 相似文献

丽江2.4 m望远镜在卡塞格林焦点上安装多个观测设备,为了最大限度地提高望远镜的观测效率,需要实现对各终端控制系统的集成控制。原有的多波段测光系统的控制程序不具备集成化的条件,需要对其进行集成化开发以满足要求。借鉴云南暗弱天体光谱成像仪和望远镜的控制系统,在Linux系统下对多波段测光系统的控制系统进行重新开发,设计并完成了3个主要部分:观测控制程序、设备控制程序和设备数据库,成功实现了多波段测光系统、云南暗弱天体光谱成像仪与望远镜统一的控制模式,使其具备与其它设备控制系统集成的能力,满足多终端集成控制的要求。 相似文献

RTS2 (Remote Telescope System 2) is a highly modular open source telescope and observatory management software package. It evolved from RTS, which was developed in Python to control a telescope aimed at observing optical transients of γ ray burts. The development of a network system capable of operating robotic telescopes is both difficult and complicated. Along with continued software development one must be concerned with maintaining operations and obtaining results. This is a review of experiences gained building a network of robotic telescopes. It focuses on describing which issues are important during development of the robotic observatory software and requirements for future development of the RTS2 package.

FAST(The Five-Hundred-Meter Aperture Spherical Radio Telescope) is an under-building radio telescope which will be the largest single dish in the world. Through the study of the central control system, in accordance with the actual operation of the telescope and observation process, this article introduces the physical models for engineers and observers, the central control system architecture design, basic support modules and the necessary interfaces. We simulated observation control process and telescopes monitoring and control process, and took Active Reflector System as a subsystem example to complete the control system design and implementation using EPICS (Experimental Physics and Industrial Control System). The Central control system, with active reflector systems, feed supporting system has been taken to an integration test at Miyun model. In the case of the normal operation of the various sub-systems of the Miyun model by the central control system, a coordinated control is achieved. 相似文献

The characteristics of OSIRIS (Optical System for Imaging and low-Resolution Integrated Spectroscopy), an instrument for imaging
and low resolution spectroscopy proposed for the GTC 10m telescope, are described. OSIRIS is a multi-purpose instrument that
incorporates in a "classical design" several innovations, already tested in 4m-class telescopes, that will provide a powerful
first light instrument for the GTC.

The U.S. Air Force Phillips Laboratory will build the 3.63 m Advanced Electro Optical System (AEOS) telescope on Haleakala, Maui. The Institute for Astronomy will participate in this project and will develop astronomical instruments optimized for using the AEOS telescope in survey projects. As part of this instrument development program 1024×1024 HgCdTe near-infrared detector arrays will be developed at the Rockwell International Science Center. 相似文献

The Taiwan Oscillation Network (TON) is a ground-based network to measure solar intensity oscillations to study the internal structure of the Sun. K-line full-disk images of 1000 pixels diameter are taken at a rate of one image per minute. Such data would provide information onp-modes withl as high as 1000. The TON will consist of six identical telescope systems at proper longitudes around the world. Three telescope systems have been installed at Teide Observatory (Tenerife), Huairou Solar Observing Station (near Beijing), and Big Bear Solar Observatory (California). The telescopes at these three sites have been taking data simultaneously since October of 1994. Anl – v diagram derived from 512 images is included to show the quality of the data. 相似文献

We outline the basic idea of an automatically working telescope based on inexpensive commercially available hardware components. A new generation of the control software is proposed which makes the full remote control of the telescope via Internet network possible - without human factor. The main scientific goal is to provide quasisimultaneous optical data for gamma-ray satellite projects such as CGRO, HETE, INTEGRAL etc. The telescope will automatically investigate the positions of high energy sources such as GRB and AGNs, at optical wavelengths. The automatically operated burst alert telescope is expected to improve our knowledge of these astrophysical objects. The proposed experiment is different from the OTM Optical Transient Monitor which is monitoring experiment unrelated to satellite data. The system can be also applied in other areas of astronomy and astrophysics as well as provide sky patrol. 相似文献

A new architecture is presented for a Networked Signal Processing System (NSPS) suitable for handling the real-time signal processing of multi-element radio telescopes. In this system, a multi-element radio telescope is viewed as an application of a multi-sensor, data fusion problem which can be decomposed into a general set of computing and network components for which a practical and scalable architecture is enabled by current technology. The need for such a system arose in the context of an ongoing program for reconfiguring the Ooty Radio Telescope (ORT) as a programmable 264-element array, which will enable several new observing capabilities for large scale surveys on this mature telescope. For this application, it is necessary to manage, route and combine large volumes of data whose real-time collation requires large I/O bandwidths to be sustained. Since these are general requirements of many multi-sensor fusion applications, we first describe the basic architecture of the NSPS in terms of a Fusion Tree before elaborating on its application for the ORT. The paper addresses issues relating to high speed distributed data acquisition, Field Programmable Gate Array (FPGA) based peer-to-peer networks supporting significant on-the fly processing while routing, and providing a last mile interface to a typical commodity network like Gigabit Ethernet. The system is fundamentally a pair of two co-operative networks, among which one is part of a commodity high performance computer cluster and the other is based on Commercial-Off The-Shelf (COTS) technology with support from software/firmware components in the public domain. 相似文献

A first generation sodium Laser Guide Star Adaptive Optics System(LGS-AOS) was developed and integrated into the Lijiang 1.8 m telescope in 2013. The LGS-AOS has three sub-systems:(1) a 20 W long pulsed sodium laser,(2) a 300-millimeter-diameter laser launch telescope, and(3) a 37-element compact adaptive optics system. On 2014 January 25, we obtained high resolution images of an mV8.18 star,HIP 43963, during the first light of the LGS-AOS. In this paper, the sodium laser, the laser launch telescope,the compact adaptive optics system and the first light results will be presented. 相似文献
