In the analysis of passive radar using GSM signal as illuminator of opportunity, the Ambiguity function of GSM signal is investigated.

As a complicated communication signal GSM signal is of great measurement significance.

The design of an intelligent monitor system for distribution transformer based on GSM communication is introduced.

Aimed at several communication means used between the Remote Terminal Unit(RTU) for hydrological and central station transmitting data, this paper analyses the characteristics of these means, introduces GSM communication and GSM short messaging service(SMS).

With the GSM cellular engine embeded into the measurement and control system and specially designed software and hardware, the wireless computer measurement and control system that utilizes GSM communication net to transfer and receive instructions and data settles the above problems completely.

The maintenance of automatic weather station in the form of GSM short message;

Development of Message Management System Based on GSM Short Message;

This paper presents the main architecture of a vehicle monitoring and dispatch system,which is recently developed with three kernel technologies,which are GPS receivers,the GSM communication network and the GIS software, as its technical basis.

The measurement system of channel flow based on GSM short message service;

With the rapid development of mobile communication service in the world,GSM short message service has have broad users because of its characteristics of fast convenience and low price.
