A reference system in GNSS is needed to establish a common framework for determining the positions of satellites and receivers on Earth. This system provides a consistent coordinate system that allows accurate positioning and navigation globally. Without a reference system, it would be challenging to interpret and use the satellite data collected for navigation purposes.
European GNSS Agency was created in 2004.
The ILS Z is an Instrument Approach Procedure which requires a GNSS capability to be executed. Though the the ILS information regarding the Localizer (Runway axis) and Glide Slope are the same for the any ILS, this one demands that before joining the ILS itself the aircraft has to fly through waypoints that can only be flown using the GNSS capabilities of the aircraft. Besides that, the Missed Approach segment of the procedure also requires GNSS capability. Note: GNSS stands for Global Navigation Satellite System.
A frame of reference is a system used to define location or state for physical objects. A reference frame is a system of objects that are not moving with respect to one another.
There is no path to ground. IE: You need to ground the generator using a ground rod.
The Global Positioning System (GPS) is a space-based global navigation satellite system (GNSS) that provides location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites.Car GPS helps to track the location of the car.

There are no common 4-letter anagrams. The letters can spell the acronym gLAB (GNSS-LAB) which is a software suite developed for use with the Global Navigation Satellite System.
To identify and objects location you need three pieces of information. These are a reference point, a distance from the reference point, and a direction from the reference point.
A frame of reference in physics, may refer to a coordinate system or set of axes
If the reference points are not correct, the location of any coordinate will be incorrect.
