AMDL is one of the first companies to bring GPS technology into India. Strategic Electronic Division (SED) started representing GPS manufacturers as well as providing customized solutions since 1994. Recognizing its experience in developing GPS based solutions, the Department of Electronics awarded a project to develop a GPS based Vehicle Monitoring System. This project known as DPTIS was successfully completed in the year 1999.

Since then SED has not looked back. Today, SED is known for its support and service capability.

SED's constant search for the best technology products has resulted in its representing many internationally reputed product manufacturers for diverse applications like Timing, military navigation, Ionospheric research, personal navigation, Survey GPS, embedded GPS applications, Microwave products etc.

GPS - An Introduction

It is said that after the invention of computer, the most widely used innovation is the satellite based navigation system called the Global Positioning System (GPS). Though originally developed for the control, guidance and navigational applications of US military, in a very short span of time this technology has pervaded almost every aspect of human life.

GPS technology is based on a constellation of 24 satellites revolving in 6 orbits. These satellites transmit very precisely time synchronized signals using which GPS receivers are able to compute their position to a very high degree of accuracy. In addition to position, GPS receivers are capable of providing high stable and accurate time information.
