S, the composite antenna 1 for radio beacons, the light receiving section 2, and the light projecting section 3 are incorporated in a head unit 4 which is a storage case.

Signals such as GPS, radio beacons, and optical beacons transmitted and received by the head unit 4 are connected to the control unit 8 via the coaxial cable 5. An amplifier 6 for GPS and a data decoder 7 are provided in the control unit 8. The data decoder 7 includes a reception data decoder for radio beacons and optical beacons, a data encoder for transmitting optical beacons, an interface, and a microcomputer.

The output of the amplifier 6 is the GPS antenna output 10
Is connected to the GPS antenna input section of the navigation unit, and the reception data of the radio wave beacon and the optical beacon, the transmission data of the optical beacon, and the like are transmitted to the VICS terminal 9
It is connected to the navigation unit via and communicates. This allows the navigation unit to display latitude, longitude, altitude, time, speed, road traffic information, and the like.

FIG. 2 shows the details of the head unit 4. First, the GPS system is composed of an antenna element 12, a low noise amplifier 13, a bandpass filter 14, and amplifiers 15 and 16 in the 1.5 GHz band. There is.

The received radio wave from GPS is -100 dBm.
Because of the following weak radio waves, a low noise amplifier 13 having a low noise figure (NF) is provided in the preceding stage, and a bandpass filter 14 is inserted to avoid interference from other systems. Further, the amplifiers 15 and 16 have a function of ensuring the amplification degree necessary for keeping the NF low and compensating for the loss due to the coaxial cable.

Next, the radio beacon system is composed of a 2.5 GHz band antenna element 17, a low noise amplifier 18, and a band pass filter 19. Here, similarly to GPS, since the received radio wave is a weak radio wave of about -90 dBm, the low noise amplifier 13 having a small noise figure (NF) is provided in the preceding stage, and the bandpass filter 14 for avoiding interference from other systems is provided. I'm inserting it. However, compared to GPS, the strength of the received radio waves is high,
Although the amplifier after the bandpass filter 14 is omitted, the amplifier may be inserted in the same manner as the GPS system depending on the loss of the coaxial cable or the like. Here, the antenna element 12 of GPS and the antenna element 17 of the radio beacon are shown independently in the figure, but in this embodiment, these are combined antennas.

The first feeding method for compounding the antenna elements is a method for feeding one element at the same point and receiving different frequencies from one element.

The optical beacon type light emitting section is composed of a light emitting diode 25, a driver 26, a pre-driver 27 and a band pass filter 28. The band-pass filter 28 has a frequency band different from that of the band-pass filter 22 of the light receiving section, and functions to separate the transmission signal transmitted from the control unit 8 from other reception signals. The separated transmission signal is waveform-shaped by the pre-driver 27, and the light-emitting diode (LED) 25 is passed through the driver 26.

After the direct current component is cut by the direct current blocking capacitors 29, 30, 31, 32, it is coupled to the coaxial cable 5 via the mixer 33a and connected to the control unit 8. At this time, the mixer 33a has a function of matching the input / output impedances of the transmission / reception signals and coupling them to the coaxial cable 5.

On the other hand, a DC voltage is supplied from the control unit 8 to the coaxial cable 5, so that the above-mentioned radio wave reception signal and optical transmission / reception signal are superposed on this DC component and controlled by the coaxial cable 5.

The head unit 4 serves to supply power to the entire head unit 4.

The GPS reception signal separated by the distributor 33A is connected to the navigation unit via the amplifier 16A for compensating for the relay loss in the control unit 8 and the DC blocking capacitor 32. If the relay loss is small, the amplifier 16A may be omitted, and at this time, the amplifier 16A is directly connected to the navigation unit via the DC blocking capacitor 32A by a coaxial cable or the like.

The received signal of the radio beacon separated by the distributor 33A is input to the radio beacon signal demodulation unit 36,
Here, the data signal is demodulated, and the data processing unit 39 reproduces the data. The received signal of the optical beacon also demodulates the data signal in the optical signal demodulation unit 37 in the same manner as the radio beacon,
The data processing unit 39 reproduces the data. On the other hand, the transmission signal of the optical beacon is obtained by modulating the data processed by the data processing unit 39 into a data signal by the optical signal modulation unit 38 and distributing the data to the distributor 33A.
