Specification for GPS & MSF Clock Drivers
Drivers can be provided for most types of Clock devices. There are several ways to handle automatic date and time updates as follows:
- Many devices are supplied with their own synchronization software which directly sets the computer clocks. Whilst these have their uses they are often installed as services running invisibly in the background which makes it difficult to disable them when needed.
- Commercial clocks normally have an output port either a comm port or USB port that program developers can connect to. Data is often output as a text stream and can be easily read and processed.
- Time Servers are often used on large systems where numerous computers and LAN based devices need to be kept in sync.
Correct installation is the key to good time signal reception. This is particularly important for the GPS clocks as the arial must be able to receive signals from as many satellites as possible. There is usually a minimum number of satellites required, and will be specified by the manufacturers. This can often be between 8 and 12. If these are not available the time updates can fail.
QSL have developed a number of clock applications that allow time updates to be controlled and distributed to other devices when required.
