MIL-STDS and PTTI - What's Available and What Needs to be Done
Abstract
The systems developer who needs PTTI capability has relatively little guidance in the form of military standards, particularly for systems using atomic clocks or other sources of very precise time and frequency. This paper will discuss the existing standards, including MIL-STD-188-115, MIL-F-2991 (EC), and DOD-STD-1399. These documents were written several years ago and do not always reflect current practice or take advantage of more recent technology improvements. User needs have also changed over the years and some of those needs such as more detailed time codes are not being met. We will summarize what's available and what's good and bad about it. The second part of the paper will make suggestions about what should be done in the future to promote and facilitate good PTTI design practice. Topics will include clock performance parameters, environmental considerations, time codes, signal isolation and time dissemination.
