Abstract

The invention provides a satellite searching system and a satellite searching method with a satellite signal mistake-locking prevention function, and relates to the communication field of the satellite. The satellite searching system comprises a microprocessor MCU unit, a high frequency head, a frequency converter, a demodulator and a positioning module; the high frequency head receives a satellite signal transmitted by an antenna feed source; the frequency converter performs amplifying and down conversion on the signal output by the high frequency head; the demodulator demodulates the signaloutput by the frequency converter into a standard transmission signal according to the transmission standard (DVB-S, DVB-S2, ABS-S) of the satellite signal; and the MCU unit obtains a signal quality value of the current satellite signal from the demodulator and drives the positioning module according to the signal quality value to enable the antenna to search the satellite automatically so as to complete satellite signal locking. By virtue of the satellite searching system, the problem of easy mistake locking (the antenna plane of the satellite antenna is not aligned to the corresponding satellite) of the automatically tacking satellite antenna can be solved, so that the satellite searching system can be applicable to a vehicle platform and a shipborne platform, and is low in use cost, simple in control, convenient to operate and high in stability.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to a star-seeking system and a star-finding method for preventing mislocking of satellite signals. Background technique [0002] With the continuous development of the RV industry and the improvement of people's living standards, the demand for RVs is also increasing. At the same time, it drives the demand for vehicle-mounted satellite antennas and puts forward higher requirements for product quality and ease of use; enterprises It is necessary to continuously improve the quality of products to improve the viability of products in the market. [0003] Most of the existing technical solutions for automatic tracking satellite antennas use the signal voltage of tracking satellites to lock satellites; by cooperating with hardware amplifiers, a threshold voltage is set, and when the detection is higher than the threshold value, it is considered that the antenna has found a satellit...
