Problems solved by technology

[0002] At present, the existing satellite signal measurement devices do not provide independent power supply. Before measuring satellite signals, they must be connected in series between the satellite antenna and the receiver. The basis of the satellite cannot be accurately positioned
The existing satellite signal measurement device must lead the power supply to the satellite antenna, which brings great inconvenience to the user's use and operation
[0003] At present, in the transmission of satellite signals, most of the transmissions use digital signals, so the existing satellite signal measurement devices for finding satellites by measuring analog signals no longer meet the requirements of current applications

Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0042] figure 1 It is a block diagram of the digital star finder of the present invention, as figure 1 shown, including:

[0043] The signal acquisition unit 101 is configured to acquire the satellite identification to be found from the outside, and send the satellite identification to the main control unit 100 . The satellite identification can be letters or numbers entered through a peripheral keyboard, such as a satellite name; or the longitude and latitude of the location of the digital star finder can be obtained from the outside, such as input through a peripheral keyboard;

[0044] The main control unit 100 is used for controlling each component unit in the digital star finder and coordinating the work among the units. The main co...

Abstract

The invention discloses a portable frequency-spectrum digital star finder, which has main functions of finding a satellite position, and providing the exact satellite position when satellite antennas are installed. The portable star finder is provided with power supply units that bring great convenience for users to use and operate. The digital star finder presets a great number of satellite channel meters for the users to use; the users can measure satellite signals only by choosing names of the satellites, thereby avoiding preliminary work of searching the satellite channel meters. The digital star finder further provides satellite antenna parameters obtained according to local latitude and longitude, thereby ensuring that the users conveniently realizes the initial location to the positions of the satellite antennas, increasing star-finding speed, and downloading latest satellite channel data from instrument websites at any time, so as to ensure that the instrument storage data is consistent with the satellite channel parameters.

Description

technical field [0001] The invention relates to satellite signal measurement technology, in particular to a portable frequency spectrum digital star finder. Background technique [0002] At present, the existing satellite signal measurement devices do not provide independent power supply. Before measuring the satellite signal, they must be connected in series between the satellite antenna and the receiver. The basis of the satellite cannot be accurately positioned. The existing satellite signal measuring device must lead the power supply to the satellite antenna, which brings great inconvenience to the use and operation of the user. [0003] At present, most of the satellite signal transmissions use digital signals, so the existing satellite signal measurement devices that measure analog signals to find satellites no longer meet the requirements of current applications. Contents of the invention [0004] In view of this, the main purpose of the present invention is to pr...
