Telescope remote control method based on iridium star point-to-point communication mode

Abstract

The invention relates to a telescope remote control method based on an iridium satellite point-to-point communication mode, which is characterized in that the method comprises the following steps: an iridium MODEM is connected with a local control host of the telescope by a standard RS232 interface; a remote control host can be provided with a common MODEM or the iridium MODEM; the remote controlhost can establish a communication link with the local control host by the way of dialing a special number of the iridium MODEM at the local control host; after the communication link is established,the two parties mutually send control orders and state information to carry out the telescope remote control. The telescope remote control method overcomes the control difficulties of control systemsof unattended astronomical telescopes in sparse and remote areas, and solves the following technical problems: the local control host carries out the remote awakening, over-weak and signal discontinuity of the iridium satellite signal, reliability of observation pictures and low cost return. The control system can form a technical proposal with practical useful values by using the iridium communication system.

Description

technical field [0001] The invention relates to a control method, in particular to a telescope remote control method based on the iridium point-to-point communication mode. Background technique [0002] With the impact of human beings on the natural environment, more and more telescope sites tend to be located in remote areas with few people. These areas have a good atmospheric environment, less pollution, and no light pollution, but there are also problems such as inconvenient transportation and communication difficulties. For example, on January 12, 2008, the Antarctic telescope CSTAR developed by the Nanjing Institute of Astronomical Optics Technology of the Chinese Academy of Sciences was transported to the Antarctic with China's 24th Antarctic scientific research ship, and successfully arrived at Ice Dome A, the highest point in the Antarctic inland. The installation has now been successfully completed . Areas like Antarctica are not suitable for human habitation, and...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned Iridium communication system cannot be simply and directly applied to the control of astronomical telescopes, because there are several technical problems:

[0006] 2. Since the telescope is located in the South Pole, even the signal of the Iridium satellite here is very weak, and the signal tends to be intermittent

In this case, if the ordinary point-to-point communication method cannot meet the communication requirements of the astronomical telescope control

[0007] 3. Due to the limitation of communication bandwidth, the signal is easy to be interrupted, and the communication cost of Iridium is very high. If the observation pictures are sent back in a normal way, the cost may be very high and the efficiency is not high

[0008] Utilizing the Iridium communication system to solve the unattended astronomical telescope control problem needs to solve the above-mentioned technical difficulties, but there is no effective solution in the prior art
