Satellite signal source pointer type wristwatch

Abstract

The invention discloses a satellite signal source pointer-type watch and relates to a watch, comprising a watch shell, a dial plate and pointers; the interior of the watch shell also comprises a mini-type satellite signal receiver, a microprocessor, one or more mini-type reduction boxes, and an information window which displays time, latitude and longitude coordinates, altitude, movement velocity and direction information; the mini-type satellite signal receiver is electrically connected with the microprocessor; the microprocessor is electrically connected with the drive of the mini-type reduction box(s); the output shaft of the mini-type reduction box is connected with the pointers. The dial plate is provided with scales for the pointers to indicate hour, minute and second. The satellite signal source pointer-type watch has the advantages that the watch receives signals without regional restriction and has small interference; besides, the watch has simple time calibration, accurate timing and small size, which can time, latitude and longitude coordinates, altitude, movement velocity and direction, and has other functions.

Description

Technical field [0001] The present invention relates to a watch, in particular to an analog watch. Background technique [0002] Watches, as chronographs, have a long history. In order to pursue the accuracy of timekeeping, new watches are emerging one after another. RCC radio-controlled watches are an example. The RCC radio wave watch refers to a watch that can receive the standard time message sent by the ground timing base station for timing calibration. The ground timing base station transmits the standard time by carrier wave, referred to as RCC. The shortcomings of the RCC radio wave watch are: 1. Although the radio wave watch It has automatic calibration and correction of time error, but because the signal source it receives is the radio wave signal emitted by the ground transmission tower, its coverage radius is about 1500 kilometers, the coverage area is limited, and the signal is easily affected by the geographical environment, such as mountains. The influence of the bu...

The RCC radio-controlled watch refers to a watch that can receive the standard time message sent by the ground timing base station for timing calibration. The ground timing base station sends the standard time in the form of a carrier wave, referred to as RCC. The disadvantages of the RCC radio-controlled watch are: 1. Although the radio-controlled watch It has automatic calibration and correction of time error, but because the received signal source is the radio wave signal emitted by the ground transmission tower, its coverage radius is about 1500 kilometers, the coverage is limited, and the signal is easily affected by the geographical environment, such as high mountains The impact of the building makes the strength of the signal attenuate with the farther the transmission distance. The remote area from the signal source will not be able to receive the signal normally. Even in the area where the signal radiates, the signal will be interfered or have no signal due to complex terrain. resulting in signal receiving dead angle

2. The RCC time service system uses the long-wave frequency band between 40KHZ and 100KHZ as the carrier. This frequency band also happens to be the frequency band of many interference sources: such as: household appliances in people's daily life, switching power supply; industrial substations, frequency conversion Devic...
