@Martain2 could you give us information on Beidou [2] NAV signal, although I find this particular information about signal "could not be guaranteed" to be BS clearly Beidou has become successful competitor.

American website Defensenews.com reported in early May that Pakistani military experts were in favour of using the Chinese system, even though the availability of the signal could not be guaranteed in case of conflict.

i dont think you are understanding the "could not be guaranteed" part correctly.

it means that china reserves the right to disable service in a given area at will(similar to gps, which was block in the 2008 russia-georgia war region) it does not mean that there isnt coverage, it just means china can shut off that coverage at will. hence no guarantees


also heres an interesting piece on the signals

You want guarantee? Build your own GPS system...

But not every countries has the mean(financial and technology) to do it. Only a few chosen one can do it.
 
BUT you have to know that Chinese "Beidou (Compass) ~ Pakistan" vs "US GPS ~ Russia" are two very different scenarios. Jargons are standard contractual wordings.
