Line 75:

* [[BeiDou]] Coordinate System, China Terrestrial Reference Frame (CTRF) 2000 = ITRF97 at epoch 2000.0; own implementation.

* [[GLONASS]] [[PZ-90|PZ-90.11]] is nominally its own system, but is quite close to ITRF and uses many of the same techniques.<ref name=gtrf/>

National systems:

* United States: WGS 84 (see above); domestic use is mainly based on [[NAD 83]] instead.

* China: CTRF 2000 per above.
