(Caveat) I'm more familiar with satellite-based navigation systems. Beidou/Compass is another out of China. India has their own navigation system called IRNSS or NAVIC as of 2016. There are an additional bunch of augmentation systems, known as SBAS, in operation around the world. QZSS from Japan, WAAS in the USA, EGNOS in Europe. Some places also have differential GPS satellites in orbit, like MTSAT in Japan.
