Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio apparatus used in the field of radio communication, for example, using a satellite to synchronize the transmission timing of radio waves transmitted from a radio base station.

[0002]

2. Description of the Related Art FIG. 4 is a schematic diagram of a conventional radio apparatus. In FIG. 4, reference numeral 1 denotes a wireless device, which includes a transmitting antenna 2, a GPS antenna 3, a transmitter 4, and a GPS receiver 5. The transmitter 4 transmits a signal modulated by a predetermined modulation method on a carrier having a predetermined frequency, and the transmission antenna 2 radiates the carrier into the air. The GPS antenna 3 receives a signal transmitted from the satellite S. The GPS receiver 5 receives signals transmitted from a plurality of satellites S6 to S8 that transmit information to the ground, and receives the received data. This is to extract more positional information and time information.

As a procedure for installing the wireless device 1 having the above-described configuration, the GPS receiver 5 is automatically transmitted from the satellite S when the wireless device 1 is turned on after the wireless device 1 is attached to a predetermined place. To start receiving signals. The operator waits until the GPS receiver 5 receives the necessary number of signals from the satellites S after turning on the power of the wireless device 1 and the acquisition of the satellites is completed. Confirmation of the start-up completion in which the GPS receiver 5 captures the required number of satellites S is performed by lighting an operation confirmation LED or the like in the wireless device 1. Then, when the start-up of the GPS receiver 5 is completed, the transmitter 4 included in the wireless device 1 starts the transmission operation according to a predetermined protocol.

[0004]

However, in the wireless device 1 configured as described above, it is necessary to first select a place where the GPS receiver 5 can capture a predetermined number or more of the satellites S in the installation stage. is there. However, it takes about several minutes for the GPS receiver 5 to capture more satellites S than necessary and complete the start-up operation. Therefore, if the selection of the construction place of the wireless device 1 is inappropriate,
Since the satellite S cannot be captured, the GPS receiver 5 cannot be activated, but at this time, the operator cannot activate the GPS receiver 5 due to a failure of the wireless device 1 or the satellite S is poorly received due to a problem in the construction place. There is a problem in that it is not possible to easily determine whether the system cannot be started because it cannot be performed, or whether the startup operation is simply taking a long time. Therefore, regardless of whether the installation location is an appropriate location or not, the worker must be there for a while after the installation, so that when installing the wireless device 1, a very long installation time is required. As a result, the work efficiency was not excellent.
