基于Android的航迹指示仪的设计与实现

The Design and Implementation of Track Indicator Based on Android Platform

基于Android平台,利用GPS定位技术和百度地图开源SDK,设计了一款能够预先设定轨迹以及进行轨迹记录和保存的软件.该软件通过百度地图API进行地图显示,可根据需求通过经纬度坐标预先设定轨迹,并实时记录使用者的移动轨迹,与预设轨迹进行对比,当偏离预设轨迹一定范围时会有语音以及文字提醒.软件采用SQLite轻型数据库存储预设轨迹与记录的轨迹内容.经过测试,该软件简便易用,能够准确地记录轨迹,满足航空测磁对于航迹规划和航迹记录的需求.

Based on the Android platform,using GPS positioning technology and the open source SDK of Baidu Map,a software that can set track in advance and record the track is designed.The map is displayed through the Baidu Map API.It can set the track in advance by the latitude and longitude coordinates according to the demand,and record the user＇s moving track in real time.It can be compared with the presupposition track,and there will be voice and word reminding when the track is deviated from a certain range.SQLite lightweight database is used to store the preset track and record track content.Test results show that the software is simple and easy to use,and can accurately record the track.The software can meets the aviation magnetic measurement demand for track planning and track recording.
