[edit] Accuracy
What is the todays standard accuracy of a DME?
According to the DME section of the 2001 Federal Radionavigation Systems (2001 FRS) publication released by the DOD and DOT, Page 3-29:
Accuracy (2 sigma)
- Predictable - The ground station errors are less than ±0.1 nm. The overall system error
(airborne and ground RSS) is not greater than ±0.5 nm or 3 percent of the distance, whichever is greater.
- Relative - Although some errors could be introduced by reflections, the major relative
error emanates from the receiver and flight technical error.
- Repeatable - Major error components of the ground system and receiver will not vary
appreciably in the short term.
