本发明涉及通信技术领域，尤其涉及一种全球定位系统启动方法及用户终端。The invention relates to the field of communication technology, in particular to a method for starting a global positioning system and a user terminal.
背景技术Background technique
全球定位系统(Global Positioning System，GPS)是一个中距离圆型轨道卫星导航系统。GPS可以为地球表面大部分地区提供准确的定位、测速和高精度的时间标准。随着GPS技术的成熟，越来越多的用户终端(如智能手机)上设置有GPS模块，这给用户的生活带来了极大的方便。然而实践中发现，用户在开启用户终端中的GPS模块进行导航时，在导航过程中，经常会出现GPS掉星的情况，比如：GPS模块搜索到的卫星数量从10掉到0，这种情况下GPS模块无法对用户终端进行定位，通常需要用户手动重启GPS模块后才可以实现定位。如果在导航过程中，出现GPS掉星的次数很多，用户就需要多次手动重启GPS模块以实现定位，这使得GPS定位的效率较低。The Global Positioning System (GPS) is a medium-distance circular orbit satellite navigation system. GPS can provide accurate positioning, speed measurement and high-precision time standard for most of the earth's surface. With the maturity of GPS technology, more and more user terminals (such as smart phones) are equipped with GPS modules, which brings great convenience to users' lives. However, it has been found in practice that when the user turns on the GPS module in the user terminal for navigation, the GPS often loses satellites during the navigation process. For example, the number of satellites searched by the GPS module drops from 10 to 0. The GPS module cannot locate the user terminal, usually the user needs to manually restart the GPS module before positioning can be realized. If during the navigation process, there are a lot of GPS star drop times, the user needs to manually restart the GPS module many times to achieve positioning, which makes the efficiency of GPS positioning low.

具体实施方式detailed description
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
本发明实施例公开了一种全球定位系统启动方法及用户终端，可以提高全球定位系统定位的效率。以下分别进行详细说明。The embodiment of the invention discloses a global positioning system starting method and a user terminal, which can improve the positioning efficiency of the global positioning system. Each will be described in detail below.
为了更好的理解本发明实施例公开的一种全球定位系统启动方法，下面对本发明实施例适用的网络架构进行描述。In order to better understand a method for starting a global positioning system disclosed in the embodiment of the present invention, the network architecture applicable to the embodiment of the present invention is described below.
请参见图1，图1是本发明实施例公开的一种定位系统的架构示意图。如图1所示，该定位系统包括用户终端以及多个卫星。其中，用户终端可以包括但不限于智能手机、笔记本电脑、个人计算机(Personal Computer，PC)、个人数字助理(Personal DigitalAssistant,PDA)、移动互联网设备(Mobile Internet Device，MID)、智能穿戴设备(如智能手表、智能手环)等各类用户终端。其中，该用户终端上安装有全球定位系统(GlobalPositioning System，GPS)模块和辅助全球定位系统(Assisted Global PositioningSystem，AGPS)模块，卫星是指围绕一颗行星轨道并按闭合轨道做周期性运行的人造天体。需要说明的是，图1所示的卫星的数量并不局限于4颗，还可以包括比图1所示的更多或更少的卫星。Please refer to FIG. 1 . FIG. 1 is a schematic structural diagram of a positioning system disclosed in an embodiment of the present invention. As shown in Fig. 1, the positioning system includes a user terminal and multiple satellites. Wherein, the user terminal may include but not limited to smart phones, notebook computers, personal computers (Personal Computer, PC), personal digital assistants (Personal Digital Assistant, PDA), mobile Internet devices (Mobile Internet Device, MID), smart wearable devices (such as Smart watches, smart bracelets) and other user terminals. Among them, the user terminal is installed with a Global Positioning System (Global Positioning System, GPS) module and an Assisted Global Positioning System (Assisted Global Positioning System, AGPS) module. celestial body. It should be noted that the number of satellites shown in FIG. 1 is not limited to four, and may include more or fewer satellites than those shown in FIG. 1 .
图1所示的定位系统通常由24颗卫星组成。其中，工作卫星21颗，备用卫星3颗，平均分布在6个轨道上，每个轨道4颗卫星，在半径26560千米的近圆形轨道上运行，运行周期11小时58分钟。空间卫星系统保证地面上任何地点，任何时间都可以观测到4颗以上的卫星，并接受到卫星携带的无线电发射机连续播放的GPS导航信号。用户终端可以通过GPS模块捕获到按一定卫星截止角所选择的待测卫星，并跟踪这些卫星的运行。当用户终端捕获到跟踪的卫星信号后，即可测量出接收天线至卫星的伪距离和距离的变化率，解调出卫星轨道参数等数据(即星历数据)。根据这些数据，用户终端中的处理器就可按定位解算方法进行定位计算，计算出用户终端所在地理位置的经纬度、高度、速度、时间等信息。The positioning system shown in Figure 1 usually consists of 24 satellites. Among them, there are 21 working satellites and 3 spare satellites, which are evenly distributed in 6 orbits, with 4 satellites in each orbit, operating in a near-circular orbit with a radius of 26,560 kilometers, and the operation period is 11 hours and 58 minutes. The space satellite system ensures that more than 4 satellites can be observed at any place on the ground at any time, and the GPS navigation signals continuously broadcast by the radio transmitter carried by the satellites can be received. The user terminal can capture the satellites to be measured selected according to a certain satellite cut-off angle through the GPS module, and track the operation of these satellites. After the user terminal captures the tracked satellite signal, it can measure the pseudo-range and distance change rate from the receiving antenna to the satellite, and demodulate the satellite orbit parameters and other data (namely ephemeris data). According to these data, the processor in the user terminal can perform positioning calculation according to the positioning solution method, and calculate the longitude, latitude, altitude, speed, time and other information of the geographic location of the user terminal.
其中，用户终端也可以通过AGPS模块获取到星历数据。具体的，可以通过AGPS服务器与用户终端的交互获得用户终端的参考位置，然后通过移动网络(如GSM/GPRS、WCDMA和CDMA2000网络)将该用户终端需要的星历数据和时钟等辅助数据发送给用户终端，以辅助用户终端的GPS模块进行定位。Wherein, the user terminal can also obtain the ephemeris data through the AGPS module. Specifically, the reference position of the user terminal can be obtained through the interaction between the AGPS server and the user terminal, and then send the ephemeris data and clock and other auxiliary data required by the user terminal to the mobile network (such as GSM/GPRS, WCDMA and CDMA2000 network) to The user terminal is used to assist the GPS module of the user terminal in positioning.
然而，用户在开启用户终端中的GPS模块进行导航时，在导航过程中，经常会出现GPS掉星的情况，比如：GPS模块搜索到的卫星数量从10掉到0，这种情况下GPS模块无法对用户终端进行定位，通常需要用户手动重启GPS模块后才可以实现定位，这使得GPS定位的效率较低。However, when the user turns on the GPS module in the user terminal for navigation, during the navigation process, the GPS often loses satellites. For example, the number of satellites searched by the GPS module drops from 10 to 0. In this case, the GPS module The user terminal cannot be positioned, and the positioning can only be realized after the user manually restarts the GPS module, which makes the efficiency of GPS positioning low.
在图1所描述的定位系统中，在全球定位系统GPS模块处于开启状态的情况下，用户终端可以通过GPS模块搜索卫星，获得第一GPS卫星列表，该第一GPS卫星列表用于存储第一卫星信号信息；进一步地，用户终端可以根据第一卫星信号信息，判断GPS模块当前是否处于无效定位状态；若GPS模块当前处于无效定位状态，用户终端可以重启GPS模块。可见，通过本发明实施例，用户终端可以实时根据接收到的卫星的卫星信号信息来自动判断GPS模块当前是否处于无效定位状态，若GPS模块当前处于无效定位状态，表明当前出现了GPS掉星的情况，用户终端可以自动重启GPS模块，而不用用户手动重启，就可以实现对用户终端的定位，从而可以提高全球定位系统定位的效率。In the positioning system described in FIG. 1, when the GPS module of the global positioning system is turned on, the user terminal can search for satellites through the GPS module to obtain the first GPS satellite list, which is used to store the first GPS satellite list. Satellite signal information; further, the user terminal can judge whether the GPS module is currently in an invalid positioning state according to the first satellite signal information; if the GPS module is currently in an invalid positioning state, the user terminal can restart the GPS module. It can be seen that through the embodiment of the present invention, the user terminal can automatically determine whether the GPS module is currently in an invalid positioning state according to the received satellite signal information in real time. If the GPS module is currently in an invalid positioning state, it indicates that there is currently a GPS missing In some cases, the user terminal can automatically restart the GPS module without the user manually restarting, so that the positioning of the user terminal can be realized, thereby improving the efficiency of positioning by the global positioning system.
基于图1所示的架构，本发明实施例公开了一种全球定位系统启动方法。请参见图2，图2是本发明实施例公开的一种全球定位系统启动方法的流程示意图。如图2所示，该方法可以包括以下步骤。Based on the architecture shown in FIG. 1 , the embodiment of the present invention discloses a global positioning system startup method. Please refer to FIG. 2 . FIG. 2 is a schematic flowchart of a method for starting a global positioning system disclosed in an embodiment of the present invention. As shown in Fig. 2, the method may include the following steps.
201、在全球定位系统GPS模块处于开启状态的情况下，用户终端通过GPS模块搜索卫星，获得第一GPS卫星列表。201. When the GPS module of the global positioning system is turned on, the user terminal searches for satellites through the GPS module, and obtains a first GPS satellite list.
本发明实施例中，用户终端可以通过GPS模块搜索用户终端上空的卫星，接收搜索到的卫星所发送的信号，并分析每颗卫星的发送信号的频率、编号、运行轨迹，最终锁定卫星，获得第一GPS卫星列表，该第一GPS卫星列表用于存储第一卫星信号信息，该第一卫星信号信息可以包括卫星的标识、卫星的数量、每颗卫星所发送的信号强度值等信息。In the embodiment of the present invention, the user terminal can search for satellites above the user terminal through the GPS module, receive the signals sent by the searched satellites, and analyze the frequency, serial number, and running track of each satellite's sent signal, and finally lock the satellite to obtain A first GPS satellite list, the first GPS satellite list is used to store first satellite signal information, and the first satellite signal information may include information such as satellite identification, number of satellites, and signal strength value sent by each satellite.
202、用户终端根据第一卫星信号信息，判断GPS模块当前是否处于无效定位状态，若是，执行步骤203，若否，结束本流程。202. The user terminal judges whether the GPS module is currently in an invalid positioning state according to the first satellite signal information. If yes, execute step 203. If not, end this process.
本发明实施例中，第一卫星信号信息包括搜索到卫星的第一卫星数量以及每个卫星发出信号的信号强度值。In the embodiment of the present invention, the first satellite signal information includes the first number of satellites that have been searched for and the signal strength value of the signal sent by each satellite.
作为一种可选的实施方式，用户终端根据第一卫星信号信息，判断GPS模块当前是否处于无效定位状态的方式可以为：As an optional implementation manner, the method for the user terminal to determine whether the GPS module is currently in an invalid positioning state according to the first satellite signal information may be as follows:
判断第一卫星数量是否大于或等于最小卫星数量阈值；judging whether the first number of satellites is greater than or equal to the minimum number of satellites threshold;
若是，确定信号强度值大于最小信号强度阈值的卫星的第二卫星数量；if so, determining a second number of satellites with signal strength values greater than a minimum signal strength threshold;
判断第二卫星数量是否小于最小卫星数量阈值；judging whether the second number of satellites is less than the minimum number of satellites threshold;
若是，确定GPS模块当前处于无效定位状态。If yes, determine that the GPS module is currently in an invalid positioning state.
在该可选的实施方式中，GPS模块对用户终端进行定位时至少需要4颗卫星，故最小卫星数量阈值可以为4，当用户终端判断第一卫星数量大于或等于最小卫星数量阈值时，用户终端可以统计信号强度值大于最小信号强度阈值(如8)的卫星的第二卫星数量，并进一步判断第二卫星数量是否小于最小卫星数量阈值，若是，表明信号强度较大的卫星比较少，不足以用于GPS模块对用户终端进行定位，此时，用户终端可以确定GPS模块当前处于无效定位状态。其中，可选额，若判断第一卫星数量小于最小卫星数量阈值，也可以确定GPS模块当前处于无效定位状态。In this optional implementation, the GPS module needs at least 4 satellites when positioning the user terminal, so the minimum satellite number threshold can be 4. When the user terminal judges that the first satellite number is greater than or equal to the minimum satellite number threshold, the user The terminal can count the number of second satellites whose signal strength value is greater than the minimum signal strength threshold (such as 8), and further determine whether the number of second satellites is less than the minimum satellite number threshold. If so, it indicates that there are fewer satellites with higher signal strength. The GPS module is used to locate the user terminal. At this time, the user terminal can determine that the GPS module is currently in an invalid positioning state. Wherein, optionally, if it is judged that the number of the first satellites is less than the threshold of the minimum number of satellites, it may also be determined that the GPS module is currently in an invalid positioning state.
203、用户终端重启GPS模块。203. The user terminal restarts the GPS module.
本发明实施例中，用户终端根据第一卫星信号信息，判断GPS模块当前处于无效定位状态，表明当前出现了GPS掉星的情况，用户终端可以自动重启GPS模块，而不用用户手动重启，就可以实现对用户终端的定位。In the embodiment of the present invention, the user terminal judges that the GPS module is currently in an invalid positioning state according to the first satellite signal information, indicating that the GPS module is currently out of order, and the user terminal can automatically restart the GPS module instead of manually restarting the user. Realize the positioning of the user terminal.
在图2所描述的方法流程中，在全球定位系统GPS模块处于开启状态的情况下，用户终端可以通过GPS模块搜索卫星，获得第一GPS卫星列表，该第一GPS卫星列表用于存储第一卫星信号信息；进一步地，用户终端可以根据第一卫星信号信息，判断GPS模块当前是否处于无效定位状态；若GPS模块当前处于无效定位状态，用户终端可以重启GPS模块。可见，通过本发明实施例，用户终端可以实时根据接收到的卫星的卫星信号信息来自动判断GPS模块当前是否处于无效定位状态，若GPS模块当前处于无效定位状态，表明当前出现了GPS掉星的情况，用户终端可以自动重启GPS模块，而不用用户手动重启，就可以实现对用户终端的定位，从而可以提高全球定位系统定位的效率。In the method flow described in FIG. 2 , when the GPS module of the global positioning system is turned on, the user terminal can search for satellites through the GPS module to obtain a first GPS satellite list, and the first GPS satellite list is used to store the first Satellite signal information; further, the user terminal can judge whether the GPS module is currently in an invalid positioning state according to the first satellite signal information; if the GPS module is currently in an invalid positioning state, the user terminal can restart the GPS module. It can be seen that through the embodiment of the present invention, the user terminal can automatically determine whether the GPS module is currently in an invalid positioning state according to the received satellite signal information in real time. If the GPS module is currently in an invalid positioning state, it indicates that there is currently a GPS missing In some cases, the user terminal can automatically restart the GPS module without the user manually restarting, so that the positioning of the user terminal can be realized, thereby improving the efficiency of positioning by the global positioning system.
基于图1所示的架构，本发明实施例公开了一种全球定位系统启动方法。请参见图3，图3是本发明实施例公开的另一种全球定位系统启动方法的流程示意图。如图2所示，该方法可以包括以下步骤。Based on the architecture shown in FIG. 1 , the embodiment of the present invention discloses a global positioning system startup method. Please refer to FIG. 3 . FIG. 3 is a schematic flowchart of another method for starting a global positioning system disclosed in an embodiment of the present invention. As shown in Fig. 2, the method may include the following steps.
301、用户终端在全球定位系统GPS模块处于开启状态的情况下，通过GPS模块搜索卫星，获得第一GPS卫星列表。301. When the GPS module of the global positioning system is turned on, the user terminal searches for satellites through the GPS module, and obtains a first GPS satellite list.
302、用户终端获取第二GPS卫星列表。302. The user terminal acquires a second GPS satellite list.
本发明实施例中，第二GPS卫星列表用于存储第二卫星信号信息。该第二GPS卫星列表用于存储第二卫星信号信息，该第二卫星信号信息可以包括卫星的标识、卫星的数量、每颗卫星所发送的信号强度值等信息。In the embodiment of the present invention, the second GPS satellite list is used to store the second satellite signal information. The second GPS satellite list is used to store second satellite signal information, and the second satellite signal information may include information such as satellite identification, number of satellites, and signal strength value sent by each satellite.
可选的，用户终端获取第二GPS卫星列表的方式具体可以为：Optionally, the manner in which the user terminal acquires the second GPS satellite list may specifically be:
从GPS模块中获取第二GPS卫星列表；或，Obtain a list of second GPS satellites from the GPS module; or,
向辅助全球定位系统AGPS模块发送第二GPS卫星列表获取请求，并接收AGPS发送的第二GPS卫星列表。Send a second GPS satellite list acquisition request to the assisted global positioning system AGPS module, and receive the second GPS satellite list sent by the AGPS.
在该可选的实施方式中，一旦GPS模块定位成功，在的内存中就会保存短效星历数据，即：定位的经纬度、海拔、定位位置上空卫星的数量和轨迹以及预测四小时之内这些卫星的位置。当用户终端在下一次需要定位时，就可以直接从GPS模块中读取这些短效星历数据，就可以不用计算卫星的轨道，只需要简单的分析处理这些短效星历数据，就可以锁定卫星，从而可以缩小搜索定位卫星的范围而加快搜索到对应的定位卫星，缩短搜索卫星的时间，加快定位速度。In this optional implementation, once the GPS module is positioned successfully, the short-term ephemeris data will be saved in the memory of the GPS module, that is: the longitude and latitude of the positioning, the altitude, the number and trajectory of the satellites above the positioning position, and the prediction within four hours. the positions of these satellites. When the user terminal needs to locate next time, it can directly read the short-term ephemeris data from the GPS module, without calculating the orbit of the satellite, and only need to simply analyze and process the short-term ephemeris data to lock the satellite , so that the scope of searching for positioning satellites can be narrowed to speed up searching for corresponding positioning satellites, shortening the time of searching for satellites, and speeding up the positioning speed.
然而，GPS模块保存的短效星历数据并不是长期有效，当时间超过最小时间阈值(如4小时)，或者距离上一次定位的距离超过最小距离阈值(如1000公里)，GPS模块保存的短效星历数据就失效了，此时，GPS模块也会自动清空保存的短效星历数据。However, the short-term ephemeris data saved by the GPS module is not valid for a long time. When the time exceeds the minimum time threshold (such as 4 hours), or the distance from the last positioning exceeds the minimum distance threshold (such as 1000 kilometers), the short-term ephemeris data saved by the GPS module The short-term ephemeris data will become invalid, and at this time, the GPS module will automatically clear the saved short-term ephemeris data.
