PREDICTED STEERING COMMAND
SMARTCLOCK TECHNOLOGY Integrated with the quartz oscillator, SmartClock greatly enhances the performance of the 58503B GPS time and frequency reference receiver under both locked and unlocked conditions. In the locked condition, it has all the desirable short-term stability attributes of a stateof-the-art quartz oscillator, but it is drift free. In the event the GPS reference is lost, the combination of the quartz oscillator and SmartClock delivers performance which approaches the performance of rubidium oscillators.
SATSTAT PROGRAM The Symmetricom 58503B comes with a Windows® 3.1 program called “SatStat” which displays important internal parameters. SatStat operates on any PC which can run Windows 3.1 programs and which has a serial interface available.

Users can send text IM in a chat like way, call a contact by phone or even send an SMS to a contact.Moreover, the position of each contact can be seen on the map at any time and it is continuously updated. jChat 1.3 has been tested on the first Android phone: the TMobile G1 phone.Android jChat 1.3 setupIn order to be able to start and use the jChat 1.3 application, a few configuration steps are required. Setting the phone numberjChat 1.3 application uses the phone number as the agent ID of each contact. When running of the real phone the application tries to retrieve the real phone number using the Android API. If for some reason the phone number cannot be retrieved it must be set using the Jade Setting dialog (see Connecting to JADE)Due to some API changes from Android SDK 0.9 to 1.0, phone number customization is no more possible on the emulator. In this case, jChat 1.3 uses the emulator default telephone number and appends a random integer to ensure the uniqueness when using multiple instances of the phone emulator.Customizing the GPS location providerjChat 1.3 allows to a user to see both his position and his contact’s on a map. To do so, a mocked GPS location provider is used. jChat 1.3 used a mocked GPS service running on the phone.Since Android SDK 1.0 removed the API used by the location provider service, this solution is no more applicable.To send custom tracks to jChat 1.3 you can use the custom LocationProvider tool that is provided under/tools directory in the source tree.Please note that this tool is a standard J2SE application using Java 1.5 and swt, which has been written using the same libraries used by the ddms tool provided with Android SDK.You can easily build and run this new tool by using ant with the provided build.xmlFigure 1To do so, you have to:∙Go to <JCHAT-SOURCES-BASEDIR>\tools\LocationControlTool folder on a command shell∙Edit the build.properties file, setting android-sdk-folder property to the path of your Android 1.0 SDK∙Type ant at the shell prompt∙You should be able to see the LocationControl tool GUI.∙Launch an emulator. As soon as the emulator connects to adb, you should be able to see it in the Available Devices panel.∙Click on the emulator icon in Available Devices panel.∙Click on the Load KML… and choose a KML track file to import. You should now be able to see all the positions in the track. Please note that the KML parser only looks for data inside<coordinates> tag inside <MultiGeometry> element.Any other data shall be ignored!∙You are able to set Loop Mode (locations will be fired from beginning to end and back forever) by clicking the Loop Mode enabled checkbox.∙You are able to set the delay in milliseconds between the firing of two consecutive positions in the track, by setting it in the checkbox∙If you press the Play Route button, the default gps provider on the emulator shall begin to receive position updates. If you start jChat, you should be able to see you own position changing over time in the map tab.∙You are able to stop the update anytime by pressing Stop Route button. You are also free tolaunch a second emulator instance and send updates to it by clicking on its icon in AvailableDevices and repeating the procedure. You should be able to handle multiple emulator instances with different data playing at the same time.If you close the tool window, all the running updates shall be stopped.Launching JADE main containerTo be able to run jChat 1.3, a JADE Leap main container must be launched.A JADE Leap container MUST be running when jChat 1.3 connects to it, otherwise the application will hang.These are the steps that should be executed:1.Download the last JADE-Leap sources from 2.Unpack the sources somewhere3.Build JADE Leap for J2SE following the instruction provided with JADE sources. If the build issuccessful, a JadeLeap.jar file is available.unch a JADE Leap main container, together with JADE RMA GUI issuing the following commandjava -cp <PATH_TO_JADE_LEAP>\JadeLeap.jar -Djade_domain_df_autocleanup=true jade.Boot -guiPlease note that the option -Djade_domain_df_autocleanup=true is necessary to correctly cleanup the DF agent.Using Android jChat 1.3Connecting to JADEThe first step for using jChat 1.3 is the connection to a JADE Leap main container running on a host machine (local or remote). Please note that (differently from jChat 1.0) before connecting to Jade the screen will appear black. The GUI SHALL become visible only after a successful connection to Jade Leap.The default host machine and the port for the main container are specified on strings.xml file during compilation (this is the default value).Figure 2To change these settings perform the following steps (see Figure 1):1.Press the MENU key on the emulator2.Choose Settings3.Insert the needed settings (hos t and port and phone number if empty). You are also able to selectthe desired location provider (on a real phone you can use the GPS or the network if GPS is notavailable, on the emulator just select gps for the mocked provider). Remember that the localhost address on Android emulator is 10.0.2.2. jChat 1.3 shall now remember the settings you choose in the Jade Connection settings menu storing them as a preference, so you don’t have to enter them any time you launch the application4.Press Close button5.Press the MENU key on the emulator6.Choose Connect to Jade!If running on a real phone remember that your host must be visible through the network used (3G or wifi).If the connection to Jade platform is successful you should be able to see the new agent running on Android emulator into Jade Remote Agent Management GUI.Figure 3The name of the new agent should be the same as the phone number of the phone.Knowing jChat 1.3 tabsThe main screen is divided into two different tabs, providing contacts information in different visual ways. The Contact tabFigure 4The contact tab contains a list of all currently available contacts.Any contact can be online (connected to our JADE Leap platform) or offline.Online contacts are shown in blue, while offline contacts are shown in red.For each online contact the distance in km between the phone owner and the contact is shown.The map tabFigure 5The map tab shows the position of each online contact on a map and continuously updates their position.Each contact is visible as a pin of different colors: the phone owner can see his own position as a yellow pin, while others contacts are shown as blue pins.Maps can be seen both in traditional map mode and in satellite mode: the user is able to switch between the two modes using the switch button placed right above the map.Picking contactsTo be able to communicate with others, users must first select contacts (“picking”).You can pick one or more contacts in both contact tab and map tab.In contact tab, you have to click on the checkbox beside each contact. In map tab you simply click on the pin representation of the contact.Figure 6Please note that contact selection is local to the map (you cannot begin selecting contact in a tab, then switch to the other tab and continue selection).After contacts selection, you can decide how to interact by pressing for some seconds the emulator selection button and choosing the desired option from the context menu that will popup.Interacting with contactsUsers can communicate with contacts in three ways: SMS, phone calls or chat sessions.Sending an SMS to one or more contactsAfter choosing to send an SMS message, user will be redirected to the SMS sending screen. Obviously a message can be sent to more than one contact at the same time.Figure 7Here he will be able to enter the message text and to send it.Message shall be split into chunks if too long and sent to the desired contact/s.Please note that at the moment the emulator does not support SMS sending emulation, so nothing shall be received. The SMS sending process is mocked and it always succeeds. SMS sending process is real on the G1 hardware.Calling a contactIf you choose to call a contact, the calling screen shall appear and the call shall start.Figure 8Obviously, the phone call is totally mocked on the emulator while it is a real phone call on the G1.If you try to call more than one contact at the same time (by selecting many contacts and choosing Call from context menu) a message shall appear warning that only one contact can be called at the same time.Starting a chat sessionWe define chat session as a group of two or more contacts talking together.A chat session can be started by the phone owner (by selecting contacts and choosing Chat from the context menu) or by another contact that wants to talk with the phone owner himself.Figure 9If the user chooses to start a chat session, the chat screen shall appear. In this screen you will be able to see the list of the other session participants, to enter a text message, to send it and to see a list of all the conversation messages with timings.Using the status bar to browse chat sessionsWhenever a chat message is received from another contact, a toast notification is shown and a persistent notification is added to the status bar. Also starting a new session adds a new persistent notification.In this way the user can switch between many different ongoing conversations by using the status bar.Figure 10These are the required steps:1.Drop down the Android status bar. The list of active sessions' notifications shall appear. Please notethat you’ll have a notification for each ongoing chat session, it does not matter who started theconversation.2.Choose the session you’re interested in and click on its notification.3. A new chat session shall start (or the session switches to the new one if a chat session was alreadyopened)Each time a conversation notification is selected the chat session is redrawn.Closing a chat sessionTo close a chat session, simply press the cross button next to the send button in the chat screen.Figure 11Please note that the emulator’s BACK key will simply close the chat screen but the session will remain open (all conversation messages will be kept) and the user will be able to restore it by choosing the notification on the status bar.After choosing the cross button the session will be removed and all previously sent messages will be lost. G1 specific notesAll the selection operations must be performed by touching the screen device. The long press event for showing the Call/Chat/SMS menu must be performed by pressing a selected name for a long time in the contacts tab and by pressing the trackball in the map tab.Figure 12Entering text requires a rotation of the screen for using the QWERTY keyboard (G1 has no virtual keyboard).When screen is rotated, the height available for lists of elements (message list in the chat or contacts list in the Contact tab) is reduced.Figure 13If you want to see the full list contents, you have to scroll by moving your finger up or down on the screen.Compiling and signing jChatIn order to compile jChat you have to create a new Android Project using Eclipse, assuming that you have installed the ADT plugin in your Eclipse environment. Using the new Android Project wizard, select the “Create from existing source” and set the Location field to the directory where you downloaded jChat (i.e. C:\myprojects\jChat). For further details on how to create an Android project can be found on the Android site (/android/index.html).After the project has been created, you must set the following dependencies:∙Project→Properties→Java Build Path: select the Libraries tab then Add External JARs and move to the jChat directory select into the lib directory the JadeLeapAndroid.jar library.jChat uses the MapView in order to access the Google Maps data, so we registered the MD5 fingerprint of our debug certificate, used to sign the jChat application, to obtain a Maps API Key. Then the Maps API key reference has been added in the jChat/res/layout/homepage.xml in the MapView declaration. When you run or debug your application, ADT signs the .apk with the debug certificate and installs it on the emulator/phone. So if you want to enable your jChat project to access the Google Maps data you have to: ∙Register your debug certificate to the Google Maps service following the instructions provided at the Android site (/android/index.html) and then set your Maps API Key into the MapView declaration in <yourPath>/jChat/res/layout/homepage.xml.FAQQ: Can I have different instances of the emulator running jChat ?A: If you want to run different jChat instances you still should use the command:emulator –data <PATH_TO_IMAGE>\userdata2.imgQ: I launch the application but when I choose Connect to Jade from the menu, the application hangs. Why?A: Probably you forgot to launch a JADE Leap main container. A main container is needed for the application to start.Q: Sometimes I got a message saying “Error sending broadcast null” when closing the application. Why? A: This seems to be a known bug of Android emulator when shutting down the location update.LEGAL INFORMATIONTerms and Conditions of usejChat is an open source project supported by Telecom Italia S.p.A.

ChatGPT技术在智能地图导航中的应用指南

ChatGPT技术在智能地图导航中的应用指南随着科技的不断发展，智能地图导航成为人们日常出行的重要工具。

传统的导航系统往往只提供简单、固定的路线规划，而现在，随着人工智能的快速发展，一种新的技术——ChatGPT技术，正逐渐应用于智能地图导航中。

它基于语言模型，能够更好地理解用户的需求，提供更加智能化和个性化的导航服务。

一、ChatGPT技术简介ChatGPT是OpenAI公司开发的一种自然语言处理技术，它基于深度学习模型，并且通过与大量的训练数据相互学习，从而能够理解和生成人类的语言。

ChatGPT技术可以像人类一样进行自然语言的交流，因此在智能地图导航中具有广泛的应用前景。

二、智能地图导航的现状和问题在现有的智能地图导航系统中，用户一般通过输入地址或关键词来获取路线规划和导航指引。

然而，很多时候用户的需求不仅仅是简单的路线规划，他们可能还想了解更多的信息，比如路况、停车场情况、周边景点等。

传统的导航系统难以满足用户的多样化需求，这就给ChatGPT技术提供了一个优化和改进的空间。

三、ChatGPT技术在智能地图导航中的应用1. 个性化路线推荐通过ChatGPT技术，智能地图导航可以更好地理解用户的出行需求和个人偏好，从而为用户提供更加个性化的路线推荐。

系统可以根据用户的输入和历史数据，推荐适合用户的行车路线，并且考虑到用户的时间、交通状况、需求等因素。

2. 实时路况信息ChatGPT技术可以使导航系统能够通过自然语言交互的方式获取实时的路况信息。

用户可以通过语音或文字询问当前的交通情况，导航系统则会根据用户的问题进行解析，并提供准确的实时路况反馈。

这样，用户可以更好地了解交通状况，优化出行计划。

3. 个性化停车场推荐在城市出行中，找到合适的停车场始终是一个令人头疼的问题。

通过ChatGPT 技术，智能地图导航可以根据用户的需求和偏好，推荐附近的停车场信息。

用户可以询问某个地点附近的停车场情况，系统将根据用户的问题进行解析，并提供相应的停车场推荐，比如价格、停车位数量、地理位置等。

Selective Availability (S/A)
The Defense Department dithered the satellite time message, reducing position accuracy to some GPS users. S/A was designed to prevent America’s enemies from using GPS against us and our allies. In May 2000 the Pentagon reduced S/A to zero meters error. S/A could be reactivated at any time by the Pentagon.
