real-time GPS-datareceiving in buildings.The system consists of a High-Gain GPS-antenna for outdoor,a precisely amplifier with a helix-typ GPS-sending antenna and an integrated electronic power regulator.This enables all kinds of L1-band GPS-systems to receive an goodsignal indoor.The repeated signal could be used for system test,initialisation,and product demonstartion.The input signal power at the receiving antenna is approximately 130dBm (spreading over 2MHz),so the desired signal is below the thermal noise floor.Please read this manual before installing and working with the system.For any questions please contact the technical support from aucon by Email:*************2.SafetyThis product is conform to the EU-standarts.Please note the advices below before working.Symbols used in the description:∙ This system should only be used by the configuration from the manufacturer.∙ Before turning on the system please always check the voltage.∙ Due to current regulatory considerations,GPS repeater kits are available for work inshielded environment.Please ask your federal offices if you have any questions about regulations about in your country.∙ Please not that electrostatic discharge could damage your system,so only workunder ED-proved conditions.∙ Please also install the system in a dryenvironment.Please refer to the manual!This note is veryimportant!Please note.3.Installation3.1Installation in a buildingThe GPS-Repeater AS47/48consits of a receiving gps antenna which has to be located outdoors on the roof of a building,a special HF-cable with configured length and a sending gps antenna for distributing the signal indoor.The amplifier is integrated in the antenna and works with230V AC,or7,5to9Volts,depending on your countrys power supply.Scheme for GPS-Repeatersystems AS47/AS48:3.1.1Installation of outdoor antennaBefore installing the gps outdoor antenna please check the quality of gps signal on different days,so that you could be sure to receive a good signal on this location.You should only use an location with bright view to the sky.Please note that the outdoor antenna should not be installed in sight to thesending antenna because of interferences.This interferences could shutdown the hole system.The GPS outdoor antenna(white)should be mounted on a flatsurface on the top of a roof,or if mounting on a roof is notpossible,it could be mounted on a facade(holder availableoptional).Pull the cable through the holder of antenna,before mounting.Then bolt the connector of cable together to the antenna.Mount the antenna on the metal stand.Mount the metal stand on a flat surface.3.1.2Laying of cablesIf you install the cable,please note that there should be no strain on the cable.The cables should be mounted in a cable channel or with clamps.Ensure also that the cables have a bending radius which is big enough.A big,heavy cable with a big diameter (like f.e.AIRCOM Plus or ECOFLEX10/15)should not give a compressive load to other parts of the system like splitter(see below).So tighen the cables on the connectors to the splitters that the compressive load is minimized.Use the right cables depending on the scheme of your spezial configuredgps repeater system,do not exchange the specific cables.Ensure that theholes for the cables are big enough because the connetcors are mostlybigger than the cables.Example:Connecting an Aircom Plus cable to an GPS splitterby TNC-connector.Tighen the connectors only by hand,do not use a spanner.If you install the system on a building which has no lightening protection yet,we also offer a lightening protection to be installed into the cable by connectors.Please use UV-protection for the part of cable which is mounted directly outside the building with a free view to the sky,to protect the cover from aging.Bending radius of HF-cables in comparison:Nr Typ of cable Diameter in mm

cylinder facing against the celing or against the testing bench.Note that the signal could be attenuated easily because of the high frequency.Only your hand in front of the repeater can attenuate the gps signal clearly.You can use a small conduit for mounting the repater on a balk(see picture)or you can also use metal bracket holder.Example in a hangar:Installation site:Please see the important notes on the additional flyer which is added to every gps repeater set.Radiating characteristics:Vertical(in sending direction)Horizontal(vertical to sending direction)bei80°bei40°bei0°Note for mounting indoor:Do not mount the sending antenna(repeater)behind a heating system or something like that.Do not mount the antennas in a direct circle to WLAN or GSM-Repeaters.Connection to the power supply:Use the power supply for 230V AC which is standart in european countries.If you need to adapt the system to your countries power supply only use 7,5to 9V DC to power up the sending e an ON/OFF Switch to power up the system and shut-off the system if you do not need it.Please note that the repeater antenna is only for indoor mounting.Activation and general conditions:Please ask your federal offices if you have any questions about regulations about gps repeaters in your country.For prejudice only the customer is liable for.The GPS-Repeatersystem needs several minutes to send with full transmitting power.If not enough transmitting power is reached after severeal minutes please check the installation of the outdoor antenna if there is free sight to the sky.Also check the indoor antenna of the right adjustment to the gps testing bench in the room.Also check the connetcors of the cable.The sending antenna should not be mounted in sight to the outdoorantenna.4.Delivery Content

三星M8800实现GPS定位导航教程

三星M8800实现GPS定位导航教程

【大硕原创】谁说小八不能定位导航?三星M8800实现GPS定位导航教程【大硕原创】三星M8800实现GPS定位导航教程(追加edenpang大侠撰写的一些使用经验)入手三星m8800之初并没有太在意小八是否有GPS定位导航的功能,被他吸引完全是高质量的摄影功能和不算太高的价格(当然不是指行货)。

然而,当把小八其他功能都挖掘的差不多的时候,网上关于小八是否有GPS模块以及是否能定位导航之争不由不让人心里痒痒,不管怎么说有GPS总是件令人愉悦的事情。

M8800原机自带了一个像垃圾一样的Google地图,其并非GPS导航,而是通过测算手机周边信号发射基站的位置来推断手机大致处于什么位置,这种定位非常不准确,而且由于每次都要在线下载地图,使得流量大增,因此Google地图可谓鸡肋中的鸡肋。

那么,M8800是否真的只能实用这种垃圾地图呢?关键在于小八有没有真正意义上的GPS模块。

事实证明,小八是有GPS模块的,这个证明的过程繁杂,在此不叙。

那么接下来就是如何通过软件实现小八的导航功能。

市面上流行的手机导航软件基本上只支持智能手机,对小八这个非智能手机来说丝毫没有可能用的上。

然而,上帝是眷顾众生滴,于是“乐图”出现了。

乐图的定位是利用软件提供地图读取,然后通过手机蓝牙与外置GPS模块连接,使得原本不具备GPS功能的手机享受这一功能。

不过由于乐图支持java,使得M8800也分享了能够使用GPS定位导航的快感。

这里有必要插叙一段,由于三星手机系统封闭,在最初的时候M8800使用乐图软件时不能读取记忆卡里的离线地图包,使得实用性大打折扣。

乐图论坛的管理员alvin注意到这一情况,经过反复测试、修改终于使m8800能够完美运行乐图导航软件并顺利读取记忆卡里的离线地图,直接为大家省了很多流量钱啊,在此谢谢alvin和乐图团队!我会一直支持乐图的!好,继续正题,首先下载m8800专用版的乐图软件(附件里有),装入手机(小八如何安装软件不在此文叙述之列,如有疑问请上网上自搜)。

GPS_NMEA-0813协议详解

GPS_NMEA-0813协议详解

GPS NMEA-0183协议详解NMEA协议是为了在不同的GPS(全球定位系统)导航设备中建立统一的BTCM(海事无线电技术委员会)标准,由美国国家海洋电子协会(NMEA-The National Marine Electronics Associa-tion)制定的一套通讯协议。

GPS接收机根据NMEA-0183协议的标准规范,将位置、速度等信息通过串口传送到PC机、PDA等设备。

NMEA-0183协议是GPS接收机应当遵守的标准协议,也是目前GPS接收机上使用最广泛的协议,大多数常见的GPS接收机、GPS数据处理软件、导航软件都遵守或者至少兼容这个协议。

NMEA-0183协议定义的语句非常多,但是常用的或者说兼容性最广的语句只有$GPGGA、$GPGSA、$GPGSV、$GPRMC、$GPVTG、$GPGLL、$GPZDA等。

下面给出这些常用NMEA-0183语句的字段定义。

协议帧总说明:该协议采用ASCII码,其串行通信默认参数为:波特率=4800bps,数据位=8bit,开始位=1bit,停止位=1bit,无奇偶校验。

帧格式形如:$aaccc,ddd,ddd,…,ddd*hh<CR><LF>1、“$”——帧命令起始位2、aaccc——地址域,前两位为识别符,后三位为语句名3、ddd…ddd——数据4、“*”——校验和前缀5、hh——校验和(check sum),$与*之间所有字符ASCII码的校验和(各字节做异或运算,得到校验和后,再转换16进制格式的ASCII字符。

)6、<CR><LF>——CR(Carriage Return)+ LF(Line Feed)帧结束,回车和换行GPGGAGPS固定数据输出语句,这是一帧GPS定位的主要数据,也是使用最广的数据。

$GPGGA,<1>,<2>,<3>,<4>,<5>,<6>,<7>,<8>,<9>,<10>,<11>,<12>,<13>,<14>*<15><CR><LF><1> UTC时间,格式为hhmmss.sss。

2021年魅蓝notegps搜星慢的解决方法

2021年魅蓝notegps搜星慢的解决方法

In fact, everyone knows what they want, but not everyone has the courage to express it.同学互助一起进步(WORD文档/A4打印/可编辑/页眉可删)魅蓝notegps搜星慢的解决方法首先科普一下 A-GPS(Assisted GPS)即辅助GPS技术,它可以提高 GPS 卫星定位系统的性能。

通过移动通信运营基站它可以快速地定位,广泛用于含有GPS功能的手机上。

GPS通过卫星发出的无线电信号来进行定位。

当在很差的信号条件下,例如在一座城市,这些信号可能会被许多不规则的建筑物、墙壁或树木削弱。

在这样的条件下,非A-GPS 导航设备可能无法快速定位,而A-GPS 系统可以通过运营商基站信息来进行快速定位。

A-GPS基本思想是通过在卫星信号接收效果较好的位置上设置若干参考GPS接收机,并利用AGPS服务器通过与终端的交互获得终端的粗位置,然后通过移动网络将该终端需要的星历和时钟等辅助数据发送给终端,由终端进行GPS定位测量。

测量结束后,终端可自行计算位置结果或者将测量结果发回到AGPS服务器,服务器进行计算并将结果发回给终端。

同时后台SP可获取位置信息为其它服务应用。

接下来进入主题我们这使用定位功能时,在有网络的情况下会打开A-gps辅助定位,这个技术需要从服务器下载星历图,现在主流的星历图服务器主要有 Google,Nokia等,魅蓝note采用的MTK的解决方案,而MTK的a-gps默认的`服务器为Google的服务器,然而Google在大陆已经被和-谐,很不稳定,有时能连上有时连不上,当连不上的时候定位系统就只能通过传统的定位方式来定位,所以就会产生搜星慢的问题(搜星慢不能怪魅族,要怪只能怪ISP 和-谐了Google)。

请看下图,Google的服务器无法pinghjg,jhhhhhhhhhhhhhhhhhhhhhh通,而诺基亚的服务器轻松ping通。

SIM7100_GPS_Application_Note_V0.01(翻译中文版)全球定位系统应用说明

全球定位系统应用说明1简介1.1概述本文给出了sim7100 GPS功能的使用。

用户可以得到关于sim7100 GPS /A-GPS功能有用的信息通过这个文件迅速。

全球定位系统的功能是提供在命令格式,他们是专为客户设计他们的全球定位系统应用程序很容易。

用户可以访问这些命令通过USB接口,GPS在与sim7100模块通信。

SIM7100 GPS特征:●支持S-GPS和A-GPS功能。

●支持GLONASS功能。

●支持单机模式,MS基础模式和MS辅助模式●支持冷启动和热启动。

●支持NMEA-0183标准的一个子集。

●支持NMEA句子NMEA端口输出。

●GPS支持(用户平面)和CP(控制平面)的方法。

●MS辅助模式支持单一固定;MS为基础的模式支持连续固定。

●如果有必要的话,支持证书。

支持GPS模块上电时自动启动,它仅支持单机模式1.2全球定位系统模式介绍在辅助模式下,当一个定位的请求发出时,有效的网络信息被提供给位置服务器,并援助来自位置服务器的请求。

位置服务器向手机发送辅助信息。

手机/移动设备测量的GPS观测值给位置服务器提供GPS测量与有效网络数据(对于给定的空中接口技术)。

位置服务器然后计算定位信息,并把结果返回到请求的实体。

在以微软为基础的模式下,位置服务器所提供的辅助数据不仅包括协助手机测量卫星信号所需的信息,还包括计算手机位置所需的信息。

因此,并不是提供全球定位系统测量值和可用的网络数据回到位置服务器,而是移动计算手机上的位置,并将结果传递给请求的实体。

在独立模式下,手机直接从GPS和GLONASS卫星解调数据。

相比辅助模式,这种模式会有点降低冷启动灵敏度,和一个较长的第一次固定时间。

然而,它不需要服务器的交互和工程网络覆盖。

GPS优先于GLONASS,所以如果GPS 具有固定的位置,导航引擎将关闭全球导航卫星系统(GLONASS),以节省电力。

如果你想要GPS和GLONASS的混合,你可以先用AT指令改变模式表1 GPS操作模式1.3.4 gpsonextra辅助文件源和政策高通所产生的援助文件和高通合作伙伴托管。

GPS设置及原理教程-如何通过修改gps.conf文件来提高搜星速度

GPS设置及原理教程-如何通过修改gps.conf文件来提高搜星速度

服务器是实时变动的哦!!
2011年1月21日星期五的活动服务器情况亚洲的:

再有就是GPS不通过差时服务器,直接通过卫星信息能自动校时,不过时间慢点而已。以上为个人推测还请高手指正。 二、加快NTP的更新速度。我的mytouch4g系统的默认NTP地址是计划(一个全球性的利用空置服务器提供免费时间服务的项目,目前在全球拥有1400多台服务器。且根据地域提供服务器池功能。)的北美服务器()。这就意味着,所用的手机,不论所处的地域和服务器实际的情况,用GPS的时候都会去连接那个地址。这种不合理的情况,造成很多非北美的用户GPS定位缓慢。知道了以上原理以后我们就可以着手修改自己的gps参数来提高定位效率了。
第二、修改的原理
基于上面的介绍分析,可以通过如下的方面来提高定位的精度和速度。1.手机所在地点的卫星信号(是指手机裸露在空旷室外,卫星信号强度可以用搜星软件来测试,我在青岛,坐车在室外基本能稳定在11颗卫星,10颗能导航的水平,更改gps.conf之后的数据,之前是9颗左右,稳定定位8颗)2.手机信号3.手机的定位软件,本人使用的是gmap5.0,破解版可导航的。4.gps参数,含在gps.conf文件内由于前3条都是自然条件是不能改变的,所以我们只能通过设置gps.conf参数来提高了,
开始正题:
第三、修改gps.conf的前提条件
1.你必须ROOT
2.装个ROOT管理器例如rootexplorer
3.先备份gps.conf文件,将文件复制到smcard(不要备份在system文件夹下,否则重启的时候有可能被自动删除的)
4.因为有ROOT权限,找到System/etc/gps.conf 这个文件,先更改权限为可写,然后长按gps.conf这个文件,选择文本编辑器打开,就可以编辑了,这个时候会提示自动备份,已经有备份可以不用管了。

小米noteGPS弱的终极解决方案

小米noteGPS弱的终极解决方案

⼩⽶noteGPS弱的终极解决⽅案⼩⽶note GPS弱的终极解决⽅案我买了⼩⽶note以后,GPS问题⼀直困扰着我。

4⽉⼊的货,GPS卫星定位困难,基本⽆法⽤,我怀疑是我的机⼦个别问题,8⽉份去上海⼩⽶之家维修,维修⼈员换了⼀个主板和液晶屏(价值1800元,属于保修期内,⼩⽶售后确实不错。

不过维修⼈员也有点不负责任,没有找到实际问题就随便把好好的主板换了,对雷布斯的财产实在是种浪费)。

但是情况并未好转。

我觉得⼩⽶note的GPS确实有问题。

我的症状是,如果⽤MIUI⾃带的硬件测试,GPS信号还是可以的。

我也⽤了AndroiTS GPS Test Pro 测试,也是OK,GPS定位稳定。

但是⼀旦切⼊导航软件:Google Map(我在国外)或Waze, GPS卫星信号就中断。

之后,属于时有时⽆状态,在开车时,这样导航是完全不能⽤的。

我的移动数据⼀直处于打开状态以接收实时地图和交通信息。

从这个症状可以判断,GPS硬件(芯⽚)应该没有问题,我⽐较怀疑GPS天线的设计有问题。

感觉⽆线数据通讯对GPS接收有⼲扰,当没有数据通讯时,GPS可以,⼀旦有数据通讯时,GPS就有问题。

我觉得⼩⽶出⼚测试时,没有考虑同时有数据通讯的情况。

我同时注意到,⽤⼿按住摄像头部分,可以接收更多的卫星信号。

经过多次尝试,最后找到了解决⽅案,⾮常简单,就是在⼿机后背左上⾓摄像头处贴⼀块铝箔。

问题就解决了,信号增强很多,⼏秒钟可以定位,我在室内(平房),开车时打开GPS导航软件和⽹络收⾳机后台下载数据,都测试了,再也没有断线的情况,⾮常稳定。

我不能确定这个⽅案是否适合所有⼩⽶NOTE,或其他型号的⼩⽶⼿机,有GPS问题的同学不妨⼀试,并回帖分享结果。

9⽉12⽇更新,版本3,美化版⽹速个⼈已成功把天线安装在后盖内,详情可看回复,我没有试成功,⼤家可以试⼀下。

为了美观,我⼜花了不少时间摸索。

铝箔的形状位置⾮常敏感,⼤多数位置效果不明显。

NMEA(National Marine Electronics Association ):美国国家海洋电子协会。

实际上应为NMEA 0183。

它是一套定义接收机输出的标准信息,有几种不同的格式,每种都是独立相关的ASCII格式,逗点隔开数据流,数据流长度从30-100字符不等,通常以每秒间隔选择输出,最常用的格式为"GGA",它包含了定位时间,纬度,经度,高度,定位所用的卫星数,DOP值,差分状态和校正时段等,其他的有速度,跟踪,日期等。

NMEA实际上已成为所有的GPS接收机和最通用的数据输出格式,同时它也被用于与GPS接收机接口的大多数的软件包里。

NMEA-0183协议定义的语句非常多,但是常用的或者说兼容性最广的语句只有$GPGGA、$GPGSA、$GPGSV、$GPRMC、$GPVTG、$GPGLL等。

下面给出这些常用NMEA-0183语句的字段定义解释。

最常用的有GPGGA和GPRMC,一般为GPGGA。

并以逗号隔开。

$GPGGA语句包括17个字段。

数据帧结构及各个字段释义如下:
$GPGGA,<1>,<2>,<3>,<4>,<5>,<6>,<7>,<8>,<9>,M,<10>,M,<11>,<12>*xx
$GPRMC语句包括15个字段。

数据帧结构及各个字段释义如下:$GPRMC,<1>,<2>,<3>,<4>,<5>,<6>,<7>,<8>,<9>,<10>,<11>,<12>*hh。
