Radio telemetry is used in many remote monitoring and remote control applications, such as in environmental monitoring, pollution monitoring, weather forecasting, and other applications. In typical applications sensors are used to collect data and this data is then transmitted to a remote receiving station where it is analysed. This paper outlines the basic principles of the radio telemetry systems and gives an example to show how such a system can be designed and used in teaching the principles of radio telemetry. The designed system is based on a popular microcontroller.

This paper introduces the implementation of Industrial Telemetry and control networks over GSM-SMS (Short Message Service). A GSM (Global System for Mobile Communication) modem TC35 and microcontroller is integrated to complete data acquisition and communication to the control center. SMS is cost-efficiency means to transfer data and control information over the GSM networks. Design of the data acquisition terminal and framework of the telemetry control system is present; the system has come into use in industrial sections.

This paper describes an electronic system for telemetry and control applications of distributed systems. It consists of a portable electronic circuit (portable module) that can be connected up to various types of sensors depending on the application to be used in each case, together with a mobile-telephony communications system. Different portable modules can be used to build up a communication network governed by a central control unit (personal computer and communications system); communication can be established from the control centre with any portable module for sending or receiving information; it is also possible to modify the application programme executed in each portable module by the teleprogramming of the microcontroller system built into the latter circuit. Two applications of the network as set up are shown: analysis and transmission of a patient's electrocardiogram and the sending of a low-resolution video signal.

In these times of Faster, Better, Cheaper (FBC) spacecraft, Spacecraft Operations Automation is an area that is targeted by many Operations Teams. To meet the challenges of the FBC environment, the Mars Global Surveyor (MGS) Operations Team designed and quickly implemented two new low-cost technologies: one which monitors spacecraft telemetry, checks the status of the telemetry, and contacts technical experts by pager when any telemetry datapoints exceed alarm limits, and a second which allows quick and convenient remote access to data displays. The first new technology is Automatic Alarm Notification (AAN). AAN monitors spacecraft telemetry and will notify engineers automatically if any telemetry is received which creates an alarm condition. The second new technology is Web Telemetry Display (WTD). WTD captures telemetry displays generated by the flight telemetry system and makes them available to the project web server. This allows engineers to check the health and status of the spacecraft from any computer capable of connecting to the global internet, without needing normally-required specialized hardware and software. Both of these technologies have greatly reduced operations costs by alleviating the need to have operations engineers monitor spacecraft performance on a 24 hour per day, 7 day per week basis from a central Mission Support Area. This paper gives details on the design and implementation of AAN and WTD, discusses their limitations, and lists the ongoing benefits which have accrued to MGS Flight Operations since their implementation in late 1996.

A core temperature telemetry system is described which includes a transmitter and circuitry for signal reception, noise elimination and computer interfacing. The system is inexpensive (less than $50), easily constructed, reliable, portable, and has proven to be sensitive to rapid fluctuations in core temperature.
