Q: What is telemetry ?

Telemetry is the remote measurement or the remote collection of data which can be physical, environmental or biological.
Telemetry is typically used to gather data from distant, inaccessible locations, or when data collection would be dangerous or difficult for a variety of reasons. In telemetry, specialized instruments perform measurements of physical quantities, and store or transmit the resulting signal - sometimes after some initial signal processing or conversion.

Telemetry saves time, reduces overheads, improves customer satisfaction, provides additional selling features and in many applications has a rapid payback. The low cost of ownership coupled with the expertise of Powelectrics ensures a cost effective and reliable solution is always available.

Q: What is telematics ?

The word has a few uses but more commonly, telematics have been applied specifically to the use of Global Positioning System technology integrated with computers and mobile communications technology in automotive navigation systems.

Most narrowly, the term has evolved to refer to the use of such systems within road vehicles, in which case the term vehicle telematics may be used.

Vehicle telematics systems may be used for a number of purposes, including collecting road tolls, managing road usage (intelligent transportation systems), pricing auto insurance, tracking fleet vehicle locations (fleet telematics), recovering stolen vehicles, providing automatic collision notification, location-driven driver information services — and more particularly, dedicated short range communications DSRC in-vehicle early warning (car accident prevention) notification alerts.
Vehicle telematics systems are also increasingly being used to provide remote diagnostics; a vehicle's built-in system will identify a mechanical or electronic problem, and the telematics package can automatically make this information known to the vehicle manufacturer service organization. The telematics monitored system is also capable of notifying any problems to the owner of the vehicle via e-mail. Other forthcoming applications include on-demand navigation, audio and audio-visual entertainment content.

But the telematics industry is not limited to automotive applications. Other applications are being studied or developed for monitoring water and air pollution, for medical informatics and health care, and for distance learning. Many European countries are developing uniform policies to integrate telematics applications into government, business and education.
