All Implemented Interfaces:

javax.microedition.lcdui.CommandListener, GPSDataView

public class SatellitesView
extends AbstractCanvasView
implements GPSDataView

Shows all the satellites by azimuth and elevation using a "radar" type display (center is 90 degrees elevation, edge is 0 degrees). North is top of screen and 0 degrees elevation.

Constructor Detail

SatellitesView

public SatellitesView(javax.microedition.midlet.MIDlet parent)

Default constructor, uses midlet parent for command callbacks (e.g. shutdown) Method also inits elevations, max radius, center etc and loads the satellite icon for use on the radar

Method Detail

process

public void process(java.lang.String data)

Processes the raw GPS data - only uses the sat in view message This method

1. Creates a satellite object from the GPS data
2. Grabs a sync lock whilst it processes the currently visible satellites list
3. Removes sats from the list that can no longer be seen - i.e. have exceeded TIME_TO_LIVE
4. Adds or updates the new satellites found in the list
5. Releases lock, calls repaint
