The traditional global navigation satellite system is susceptible to the interference and the shelter and the inertial navigation error is accumulated. Based on the MEMS technology, combining the chip-scale atomic clock and the MEMS inertial measurement unit with the receiver of the global navigation satellite system, a micro positioning navigation and timing unit is formed. The atomic clock of the unit provides the precision clock signal, the unit broadcasts the positioning navigation and timing signal and the PNT nets are constructed. The units can be carried by micro-satellites or UAVs. The number of the units for the micro positioning navigation and timing system can be freely chosen and the arrangement can be freely configured. The micro positioning navigation and timing system can overcome the problems of the traditional PNT methods and change the pattern of the PNT., authors=YOU Zheng, MA Lin, authorsList=YOU Zheng, MA
