MIDlet Satellite is created to allow user of a mobile device viewing current weather situation through satellite image adapted for device's display. Its creation was based on a wisdom that one picture can speak better than 1000 words.
Satellite image shows almost entire Europe allowing MIDlet to be used outside of the borders of Croatia. Tourists or others planning trips around Europe could find it interesting.Except viewing current situation user can see satellite image animation for the last 4 hours. By getting access to such information user him/herself can predict shall the weather change or will it remain the same.The source of the satellite images is EUMETSAT.

After starting the MIDlet user gets a menu from which he can choose 2 views of the satellite images, settings, help or information about the MIDlet (Picture 1).
First option provides animation of the 8 satellite images taken in the last 4 hours. Viewing weather development through a longer time interval can help user predict weather be like in the next couple of hours. After requesting data (Picture 2) and choosing connection type (Picture 3) downloading animation to the mobile device takes a while.
The second option on the menu allows user to view the latest available satellite image.This satellite image is being refreshed every half an hour so the data user gets describes current weather conditions pretty accurately (Picture 4). Timestamp on the images is in UTC (GMT).

The third option are the settings where user can choose the size and quality (resolution) of images displayed. It is recommended to choose the settings first, before requesting satellite images.
Image size can be set as small or normal and image quality as low, medium or high. By choosing smaller picture with lower quality download time for the file is reduced and vice versa. If using default setting (size "normal" and quality "medium") it will take about 80 seconds to download image animation and 20 seconds to download last image (depending on the quality of connection and device). It is necessary to save new settings after altering them (Picture 5).


Installing MIDlet on a mobile device:

There are several ways of installing MIDlet on a mobile device, depending on Internet access possibilities and mobile device features.
1. Download to the mobile device directly from wap or html pages
It is necessary to establish Internet connection with a mobile device. If the device can access html pages user types address and chooses download .jar and .jad files. If the device does not support html user can access wap pages (satellite.wml). After downloading these files user can start using MIDlet.
2. Transfer of files from computer or another (mobile) device using IrDA or Bluetooth (recommended)
MIDlet can be transferred from one to another (mobile) device using IrDA or Bluetooth if both of the devices support it. All that is necessary is having .jad and .jar files on one of those devices. For example one can download .jad and .jar files from html pages to notebook and afterwards transfer them to the mobile device using IrDA.


Before trying MIDlet on a mobile device user can check its functionality on a cell phone microemulator on this web page. For microemulator test user must have installed JVM from Sun jre 1.4.2 or higher.
Credits go to Bartek Teodorczyk for his great MicroEmulator and Bertil Gralvik for the excellent tutorial and skin at Skinning the MicroEmulator.
