[the second embodiment]
Then, second embodiment of the present invention is described with reference to the accompanying drawings.
Additionally, the difference of the second embodiment and above-mentioned first embodiment is only to receive state grade calculating part
The computational methods receiving state grade of 47.Therefore, the structure of wrist-watch 1 of band GPS, handling process and above-mentioned the
One embodiment is identical, so omitting detail explanation.
The state grade calculating part 47 that receives of the second embodiment is receiving the satellite-signal of more than 1 and is being less than
During regulation number, count after the signal intensity of insufficient amount of satellite-signal is set as supposition signal intensity the most set in advance
Calculate and receive state grade.
Additionally, the process of the second embodiment is with the satellite-signal receiving more than 1 as condition.Therefore, exist
When regulation number was exactly the survey of 1 originally in the case of pattern, received satellite-signal number will not be produced less than regulation
The state of number.Therefore, the process of the second embodiment is applied to the satellite-signal received in the case of location pattern
It it is the situation of 1～3.Table 2 illustrates the concrete example of the computational methods receiving state grade in the second embodiment.
[table 2]
In the second embodiment, from " 20,16,12 ", select the supposition signal intensity of not enough satellite-signal,

In the case of 1 satellite-signal, continue directly to be able to receive that the probability of satellite-signal also compares when receiving
High.Therefore it is presumed that signal intensity is set to the value " 20 " higher than the signal intensity " 0 " when cannot receive.
On the other hand, when not enough satellite-signal number increases by 2 or 3, the probability of these satellite-signals can be received
Also reduce.Therefore it is presumed that signal intensity is reduced to " 16 " when not enough satellite number is 2, reduce when for 3
To " 12 ".
Further, receive state grade display part 48 use second hand 121 show reception state grade calculating part 47 counted

When the meansigma methods of a little signal intensitys is " 45 ", it is set as supposing signal intensity by its value of 50% i.e. " 23 ".
Even if in such second embodiment, it is also possible to play the effect effect as above-mentioned first embodiment
Really.
Additionally, as shown in table 2, when the satellite-signal number received in location pattern is below 3, above-mentioned
First embodiment receives state grade be also greatly reduced.Therefore, the most likely can give and be difficult to directly
Connect the impression continued to, thus interrupt receiving.
On the other hand, in this second embodiment, setting value 20 is utilized to supply the vacation of the satellite-signal that can not receive
Determine signal intensity, so compared with the location pattern of the first embodiment, it is possible to show that reception state grade shows higher
Show.Especially, in the case of receiving 3 or 2 satellite-signals, it is calculated and be shown and passes through to continue directly to receive
And the probability obtaining position-detection information receives state grade accordingly.Therefore, the user that observation reception state grade shows continues
The probability that continued access is received uprises, it is thus achieved that the probability of position-detection information also is able to improve.
[the 3rd embodiment]
