【實用工具app】HAB Modem and Tracker|最夯免費app-綠色工廠好玩App

Ground tracking app for high altitude balloons, complete with RTTY modem, offline mapping, online distributed listener integration, chase car location reporting and more.

Connecting a SSB radio to the audio in of your device will allow for payloads transmitting RTTY to be decoded and displayed on the map. The decoded data is uploaded where it can be also viewed at http://spacenear.us/tracker/ along with data from other listeners. Positions from other listeners are also downloaded so that balloons can be tracked without being able to receive the radio signals. When enabled, the location of the user can also be uploaded and displayed on the online map.

The app supports multiple balloons at once, and includes graphing for received data. The modem is automatic, only the baud rate needs setting, while signal is located and tracked automatically.

Offline mapping is provided by mapsforge, and maps can be downloaded from http://download.mapsforge.org/maps/

Most devices allow audio input via the combined headset connector. A cable is needed to convert between the combined headset connector and a connector for audio input. Suitable cables are hard to come by, and so it may be easiest to make a cable manually. For a pinout of the combined headset connector referring to http://pinoutsguide.com/HeadsetsHeadphones/samsung_moment_pinout.shtml
