Abstract

The invention discloses a global navigation satellite system GNSS of a mobile terminal, and the mobile terminal. The GNSS comprises an external GNSS antenna and the mobile terminal, wherein the external GNSS antenna is used for receiving GNSS positioning signals, the mobile terminal comprises an antenna interface connected with the external GNSS antenna, a tuner which is connected with the antenna interface and is used for adjusting a resonant point of the external GNSS antenna, and a base-band processor which is connected with the tuner and is used for positioning according to the GNSS positioning signals. According to the global navigation satellite system GNSS of the mobile terminal, and the mobile terminal, the resonant point of the external GNSS antenna is adjusted through the tuner, an optimal GNSS positioning standard combination is selected, gain of the GNSS positioning signals can be effectively improved, limits of a clearance area on GNSS antenna performance are solved, and thereby positioning accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a global satellite navigation system (GNSS) system of a mobile terminal and a mobile terminal. Background technique [0002] GNSS (Global Navigation Satellite System) can have multiple standards, such as Beidou, Galileo, GLONASS, GPS, etc. The frequency of GNSS positioning signals is mainly around 1.5G ~ 1.6GHz. However, due to the limitation of the mobile phone clearance area, the antenna efficiency or gain of each system may be different. Some systems have high efficiency and some have low efficiency, which may cause certain systems to be unable to obtain services. Contents of the invention [0003] The object of the present invention is to solve one of the above-mentioned technical problems at least to a certain extent. [0004] Therefore, the first object of the present invention is to propose a GNSS system for mobile terminals, which can increase the gain of GNS...
