租借GPS或者北斗系统？
到目前为止，人类还没有在太空打过一枪一炮。
我估计WW-III,可能会在太空发起攻击。想想，如果刚一开战，军方的GPS卫星全部都被
土共的火箭军射下来，这个仗还怎么打？
T-99直接在圣地亚哥登录，沿着I-10一直平推到迈阿密。
Tu-160直接到纽约下蛋。
三胖到夏威夷去阅兵。
太可怕了。 |

IGS - Inertial Guidance System
Tercom - Terrain Contour Matching
GPS - Global Positioning System
DSMAC - Digital Scene Matching Area Correlation
The IGS is a standard acceleration-based system that can roughly keep track
of where the missile is located based on the accelerations it detects in the
missile's motion (click here for a good introduction). Tercom uses an on-
board 3-D database of the terrain the missile will be flying over. The
Tercom system "sees" the terrain it is flying over using its radar system
and matches this to the 3-D map stored in memory. The Tercom system is
responsible for a cruise missile's ability to "hug the ground" during flight
. The GPS system uses the military's network of GPS satellites and an
onboard GPS receiver to detect its position with very high accuracy.
Once it is close to the target, the missile switches to a "terminal guidance
system" to choose the point of impact. The point of impact could be pre-
programmed by the GPS or Tercom system. The DSMAC system uses a camera and
an image correlator to find the target, and is especially useful if the
target is moving. A cruise missile can also be equipped with thermal imaging
or illumination sensors
