  The X-ray Navigation and Autonomous position Verification (XNAV) is tested
which use the Crab pulsar under the Space Test Program that use starlight
refraction. It provide the way that the spacecraft could autonomously determine
its position with respect to an inertial origin. Now we analysis the
sensitivity of the exist instrument and the signal process that use radio
pulsar navigation and discuss the integrated navigation which use radio pulsar,
then give the different navigation mission analysis and design process
basically which include the space, the airborne, the ship and the land of the
planet or the lunar. Our analysis show that we will have the stability profile
(signal-to-noise is 5) that use a 2 meters antenna observe some strong sources
of radio pulsar in 36 minutes which based on the today's technology. So the
pulsar navigation can give the continuous position in deep space, hat means we
can freedom fly successfully in the solar system use celestial navigation that
include pulsar and traditional star sensor. It also can less or abolish the
dependence to Global Navigation Satellite System (GNSS) which include GPS,
GRONSS, Galileo and BeiDou et al.
