Description

Positioning signal receiver and its operating method TECHNICAL FIELD [POSITIONING SIGNAL RECEIVER AND OPERATING METHOD THEREOF}

Various embodiments disclose an electronic device capable of receiving a positioning signal (eg, a global navigation satellite system (GNSS) signal) and an operating method thereof.

Recently, electronic devices may use a global positioning system (GPS), a global navigation satellite system (GLONASS), a BeiDou navigation system, and/or a Galileo position system based on a global navigation satellite system (GNSS) technology. For example, a GNSS may represent a system that provides positioning information about the location, altitude, and/or speed of an object on the ground using an artificial satellite orbiting space. The electronic device may provide a positioning service (or a location based service (LBS)) by obtaining location information through more satellites based on GNSS technology.

In general, the GNSS may use specific signal carrier frequencies for a positioning signal (or a location signal). For example, GPS may currently use an L1 signal (or frequency) of about 1575.42 MHz and an L2 signal of about 1227.6 MHz at frequencies in the GHz range. Recently, an L5 signal of about 1176.45 MHz can be used as an extension of GPS. For example, a GNSS receiver is being implemented to receive GNSS signals in multiple frequency bands in order for the GNSS receiver to operate more stably in a noisy or blocked environment. For example, the GNSS receiver (or an electronic device including the same) may receive an L1 signal and an L5 signal for a positioning service.

For example, the GNSS receiver may receive both the L1 signal and the L5 signal so that the L1 signal can be used when the L5 signal is not available. Such a GNSS receiver may use separate antennas and analog circuits to receive both the L1 signal and the L5 signal. The GNSS receiver can be integrated into various electronic devices such as mobile phones, smart phones, tablets, or netbooks. For example, the electronic device may be equipped with an L1 antenna for receiving an L1 signal and an L5 antenna for receiving an L5 signal. Through this, the electronic device receives a GNSS signal (eg, L1 signal and L5 signal) in a dual band of multiple frequency bands (eg, L1 band of about 1575.42 MHz and L5 band of about 1176.45 MHz), A positioning signal with high accuracy can be obtained. In general, the L5 signal of the L5 band of about 1176.45 MHz may have higher accuracy than the L1 signal of the L1 band of about 1575.42 MHz, and the L5 antenna of the electronic device (or GNSS receiver) has the reception performance of the positioning signal compared to the L1 antenna. This can be high. However, while the L5 antenna of an electronic device (or GNSS receiver) has excellent linearity and improves reception performance, it may be sensitive to a noise environment due to its high frequency characteristics, and the antenna performance (e.g.: The reception rate) may be deteriorated (or performance deteriorated). For example, the performance of the L5 antenna may be deteriorated in a situation where interference occurs, such as when a user grips or contacts a part where the L5 antenna is mounted (or positioned) in an electronic device. May acquire a positioning signal using an L1 antenna having a relatively low performance.

In the related art, an electronic device uses an L1 antenna instead of an L5 antenna when the performance of the L5 antenna deteriorates. For example, in the case of an L5 antenna, it is possible to secure performance (e.g., positioning accuracy) through technical advantages such as bandwidth and transmitted power, while various factors such as interference and/or noise make the L5 antenna May not work properly. Conventional electronic devices use only the L1 antenna instead of the L5 antenna when the performance of the L5 antenna cannot be secured, and the relative performance is relatively low (e.g., relatively low bandwidth and low transmission power) compared to the L5 antenna. Performance degradation) Due to positioning based on the L1 antenna, positioning accuracy may not be ensured.

In various embodiments, in the first antenna and the second antenna for receiving the positioning signal, when the performance of the first antenna with relatively good performance is deteriorated, the reception performance corresponding to the first antenna using the second antenna Disclosed is a method and apparatus capable of maintaining the

In various embodiments, a first antenna including a first characteristic (eg, an L5 antenna) and a second antenna including a first characteristic and a second characteristic (eg, a dual band (eg, L1+L5) antenna) are used. Disclosed is a method and apparatus capable of providing accuracy in positioning measurement based on designing and changing the characteristics of the second antenna or switching characteristics between the first and second antennas when the performance of the first antenna deteriorates. .
