奥米加A是与罗兰相类似的双曲线无线电定位系统。其主要特点是用10～30kHz的非常低的频率工作,整个系统共有八个发射站,其中七个站1978年使用,第八个站1979或1980年使用。覆盖范围达到地球90％以上。苏联有一类似的系统,同样在10～14kHz频率范围内工作。不过这个系统共有四个发射站,每个站的发射功率比任何一个奥米加站都高,看来主要是覆盖印度洋和北冰洋这一地区。奥米加用于军事地面车辆的优点是: (1)该系统是世界范围的系统,大约覆盖整个地球90％;
Omega A is a hyperbolic radio positioning system similar to Roland. Its main feature is to use a very low frequency of 10 ~ 30kHz work, the entire system has a total of eight transmitting stations, of which seven were used in 1978, the eighth station in 1979 or 1980 to use. Coverage of more than 90% of the earth. The Soviet Union has a similar system, the same frequency range of 10 ~ 14kHz work. However, the system has a total of four transmitting stations, each transmitting at a higher power than any of the Omega stations, and appears to cover mainly the Indian Ocean and the Arctic. The advantages of Omega for military ground vehicles are: (1) The system is a worldwide system that covers approximately 90% of the Earth’s entire surface;
