I think the FT-5 and LS-6 are operational. LT-3 might be as well.
I suppose Chinese JDAMs use Beidou . Article on wikipedia (yeah , I know it is not a very reliable source ) mentions that military service with 10cm accuracy is not yet operational . Is this true ?
Global system (BeiDou Navigation Satellite System or BeiDou-2)
Description
Accuracy
Coverage polygon of BeiDou-2 in 2012.
BeiDou-2 (formerly known as COMPASS)[32] is not an extension to the older BeiDou-1, but rather supersedes it outright. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit satellites for backward compatibility with BeiDou-1, and 30 non-geostationary satellites (27 in medium earth orbit and 3 in inclined geosynchronous orbit),[33] that will offer complete coverage of the globe. There will be two levels of service provided; free service to civilians and licensed service to Chinese government and military users:[14][34]
The free civilian service will have a 10 meter location-tracking accuracy, will synchronize clocks with an accuracy of 10 ns, and measure speeds within 0.2 m/s.
The restricted military service will have an accuracy of 10cm.[35][36] To date, this service has been granted only to the People's Liberation Army and to the Military of Pakistan.[37] The military signal will be available to the Pakistani Armed Forces from June 2013.[38]
The licensed service will be more accurate than the free service, can be used for communication, and will supply information about the system status to the users.
