This article describes how to create the J2ME tracking application to be installed on J2ME capable phones with an internal GPS receiver. The application will utilize the Location API available on GPS enabled phones, read the GPS location data at a specified interval, send the data via HTTP connection to a specified server.
Here is the application looks like.

Covert GPS tracking devices have made it very easy for others to track your movements without you knowing about it. There are some steps, you can take that will allow you to regain some of your privacy.
The first step is to determine of you are truly being monitored with a GPS tracking device. In order to do this, you have to physically locate the device in the vehicle, or on the equipment. You would have to know what a GPS tracking device would look like as well as where to look. Most people don’t know what a GPS tracking device looks like so many people could be looking at one and not even know it. Also, they are small enough to be hidden in the darnedest places. Most people don’t have experience in looking for these types of devices so it becomes more difficult know where or how to look for a GPS device as well. To easily overcome both of these problems, you can hire a private investigator to do a search for you, or if you want to keep it on the down low and not leave any paper trail of your search, you can buy a GPS tracking detector device and sweep any car, or equipment yourself for any GPS tracking devices.

Generally, a Real-time system utilizes a wireless network to allow you to receive your information and view the location of your asset in real-time. Real-time GPS tracking is becoming the standard for companies or individuals who wish to use a GPS locator device for tracking fleet vehicles as well as tracking assets (trailers, generators, heavy equipment).
The U.S. Satellite network was developed by the US military but now it is opened to the private sector.
Each of these solar powered satellites circles the globe making two complete rotations every day. Anywhere on Earth, there are at least four satellites "visible" in the sky.

In order to be able to utilize Google Map API for our web application, we need to get the API Key. It can be obtained for free from Google website. This Key will be valid for one URL only, so each time we move the application to another server, we need to obtain a new key for that server URL.
The Key can be obtained from this URL:
http://www.google.com/apis/maps/signup.html
Then, a page similar to the following will appear:
In the previous article we have discussed the global architecture of the GPS Tracking system which consists of the Tracking Device and Monitoring Application. In this article we will discuss about the GPS Tracking Application Monitoring.
Pada artikel sebelumnya telah dijelaskan bagaimana arsitektur global sistem GPS Tracking yang terdiri dari Tracking Device dan Aplikasi Pemantau. Pada artikel ini dibahas mengenai Aplikasi Pemantau GPS Tracking. Read more…
Sistem terdiri dari Tracking Devices yaitu alat yang secara periodik atau berdasarkan kondisi tertentu mengirimkan informasi posisinya pada saat itu. Informasi posisi diperoleh dari perhitungan data yang diterimanya dari satelit GPS yang senantiasa ada setiap saat. Pada seri artikel ini kita akan menggunakan handphone Nokia N95 yang telah dilengkapi dengan GPS receiver built in, dan membuat program J2ME sehingga hanphone dapat berfungsi sebagai GPS Tracking Device.

Untuk dapat menggunakan Google Map API pada suatu aplikasi, kita perlu mendapatkan Key yang bisa diperoleh secara gratis dari Google. Key ini hanya berlaku untuk satu URL, jadi setiap kali kita pindahkan aplikasi tersebut dari suatu server ke server lain, maka kita perlu mendapatkan key lainnya untuk server tersebut. Read more…
