Generically, such systems are called global navigation satellite systems (GNSS).
See: GNSS
There are multiple GNSS in operation for Earth, including Russia's GLONASS, China's BeiDou, and Europe's Galileo. They work similarly to GPS and NavIC, but each is operated separately.
Phones and other devices can use multiple GNSS simultaneously to improve location accuracy and speed.
