Global Positioning System (GPS) Based Auto-Synchronous Clocks have atomic clock
|
| accuracy without the need to ever program or set them. The clocks have a unique feature |
| whereby they use GPS satellite signals to automatically configure themselves. Since
there |
| is no charge for using GPS satellite signals, the clocks have zero maintenance costs
and
|
|
ensure a perpetually accurate time.

 |
Traditionally, for public areas like railway stations and bus-stands, a master slave
|
| configuration for clocks has been used. In these obsolete systems, the master clock
is
|
| closely monitored by staff for its accuracy and the slave clocks are periodically
|
| synchronized with the master clock. The traditional master-slave configuration requires a
|
| wired communication network which has its own installation costs and maintenance cost,
|
| making the total capital cost and maintenance cost of the system much higher.
|
|
|
With the fall in cost of GPS hardware, GPS clocks cost nearly same as traditional clocks |
| but have no network and/ or maintenance requirements. The clocks come with a battery |
| back up which take care of any power outages and ensure a 24X7 operation.
