The every kind of satellite-signal received is numeral by the equal corresponding conversion of analog signal by the satellite-signal detection device 300
Signal, in order to subsequently analyze the satellite-signal.
Step S130, extracts the physical features of every kind of data signal.
In embodiments of the present invention, temporal signatures, the frequency domain of every kind of data signal are extracted respectively using signal extracting algorithm
Feature, and the temporal signatures and frequency domain character of every kind of data signal are extracted simultaneously.Wherein, by extracting every kind of data signal
Temporal signatures extract the energy response of the data signal, and the numeral is extracted by extracting the frequency domain character of every kind of data signal
The spectrum energy distribution character of signal, meanwhile, by extracting the temporal signatures and frequency domain character of every kind of data signal simultaneously, so as to
Judge in follow-up analysis.By this signal extracting algorithm to realize quick processing respectively to a variety of data signals, accelerate
Processing speed.It is the step for the method that a kind of satellite-signal provided in an embodiment of the present invention is transmitted safely specifically, refer to Fig. 3
The schematic flow sheet of rapid S130 sub-step, step S130 includes：
Step S131, extracts the temporal signatures of every kind of data signal, and the temporal signatures include the data signal
Time-domain power and receive the deflection of the satellite-signal.
In embodiments of the present invention, use
The time-domain power of every kind of data signal is taken, wherein, in represents the data signal of temporal signatures to be extracted, and Avg is represented
The average value of time-domain power, RMS represents the root mean square of time-domain power.Pass through the time-domain power and numeral letter of the data signal
Number reach that Time Calculation goes out the deflection of the corresponding satellite-signal of the data signal.Especially by InitDevice＆Set

WhileExtract the frequency domain character of every kind of data signal.
The physical features of every kind of data signal are sentenced by step S140 according to default convolutional neural networks model
Break to determine whether the data signal is signal to attack.
The default convolutional Neural networking model is trained by a large amount of known satellite-signals, i.e., a large amount of by collection
The physical features of known satellite-signal, include the temporal signatures and frequency domain character of the corresponding data signal of satellite-signal, to big
The physical features of the known satellite-signal of amount are trained, and then the satellite-signal newly received can be told according to training result are
No is signal to attack.Therefore, the physical features of the every kind of data signal of the default convolutional neural networks model to newly receiving enter
Row judges, to determine whether the data signal is signal to attack.
Step S150, if one or more of which data signal is signal to attack, the numeral to being determined as signal to attack
Signal carries out Information recovering to send the corresponding satellite-signal of non-attack signal to the smart machine, in order to user security
Check current satellite signal.
If current one or more data signals are signal to attack, show this one or more data signals be corresponding to defend
Star signal is dangerous, then needs to carry out Information recovering to the data signal for being currently determined as signal to attack, to ensure that user receives
To the satellite-signal of safety.In embodiments of the present invention, to being determined as that the data signal of signal to attack carries out the side of Information recovering
Formula has two kinds,
One of which Information recovering mode is：
According to the confidence levels pre-seted from the non-attack signal of a variety of data signals, confidence levels highest is selected
The corresponding satellite-signal of non-attack signal send to smart machine so that user security checks satellite-signal.Specifically,
As changed the numeral formed by gps signal, GLONASS signal and Big Dipper signal respectively when a variety of data signals
Signal, when the corresponding data signal of gps signal therein is judged as signal to attack, then from the corresponding number of GLONASS signal
According to the confidence levels pre-seted in word signal and the corresponding data signal of Big Dipper signal both non-attack signals, selection
The corresponding satellite-signal of confidence level highest non-attack signal is sent to smart machine, and the confidence levels of the satellite-signal can be with
It is configured as needed, i.e., user can be configured as needed.When in GLONASS signal and Big Dipper signal, the Big Dipper
When the confidence levels of signal are higher than the confidence levels of GLONASS signal, then prioritizing selection is by the corresponding numeral of Big Dipper signal
Signal is converted to after satellite-signal, is sent to smart machine, so that safe satellite-signal can be viewed by obtaining user, is unlikely to
By the satellite-signal steal information of others attack.
Another Information recovering mode is：
, according to the confidence levels pre-seted, confidence levels highest will be selected in the non-attack signal of a variety of data signals
The corresponding satellite-signal of non-attack signal with the power emission more than signal to attack to the smart machine, to suppress described attack
Signal is hit in order to which user security checks current satellite signal.
Specially：If the satellite-signal detection device 300 receive satellite-signal include gps signal, GLONASS signal with
And Big Dipper signal, the data signal that wherein gps signal is converted into is judged as signal to attack, then from GLONASS signal and north
According to confidence levels in bucket signal, confidence levels highest non-attack signal is selected, if the confidence levels of Big Dipper signal
Higher than the confidence levels of GLONASS signal, then by Big Dipper signal with satellite-signal corresponding more than signal to attack, i.e. GPS letters
Number power emission to smart machine, to suppress gps signal, in order to which user can receive safe satellite-signal, this information
The mode of recovery is applicable to a range of satellite-signal attack.In addition, whether the interval scheduled time detects signal to attack
In the presence of if signal to attack is present, continuing the corresponding satellite-signal of confidence levels highest non-attack signal with more than attacking
The power emission of signal is hit to smart machine, in embodiments of the present invention, is set at interval of half an hour, once attack is believed for detection
Number whether also exist.If signal to attack is not present, satellite-signal is normally pushed into smart machine, in order to which user checks.
Step S160, if a variety of data signals are not signal to attack, according to a variety of numerals pre-seted
The confidence levels of signal, the corresponding satellite-signal of data signal described in selection confidence levels highest is launched to the intelligence
Equipment.
If in a variety of data signals not being signal to attack, the GPS letters that such as the satellite-signal detection device 300 is received
Number, the data signal that is converted into GLONASS signal and Big Dipper signal be not signal to attack, then according to a variety of data signals
Confidence levels, the corresponding satellite-signal of selection confidence levels highest data signal, i.e. gps signal, GLONASS signal
And one kind in Big Dipper signal, send to smart machine, in order to which user checks.
