本App提供了在iOS平台上查看APRS地图数据的功能。 由国内hamclub.net提供实时APRS数据服务，极速查看APRS站台位置信息，避免访问国外服务器的龟速等待。 APRS是自动位置报告系统(Automatic Position Reporting System)的缩写，是一项业余无线电活动内容。由美国业余无线电爱好者Bob Bruninga(WB4APR)创建。全世界各地的业余无线电用户通过无线电波，把各个站台、位置、气象等实时信息发布到APRS网络上。 The "APRS Map Viewer" app is designed to provide a utility for HAM to view their APRS/HAM stations on map in a simple/focused way. Users could get the stations callsign, transmitting power,moving track and speed/altitude from the map by tapping the marker if available. Also user could get the latest received aprs log message in the detail view for diagnosing.
