Pressumably, some reference point must be used - for example, two distant stars or galaxies, the Sun and a distant star, etc.
On the Earth the directions are relative to the surface of the earth. EG noth south etc etc. The speed too is relative. Once you leave the relativity of the Earth, the directions North , south etc become un usable. There would be no Gyroscopic compass. So The space map is to be imagined in 3D. Once you leave the earth's gravity you are pretty much on your own. on the Space map of 3D the transit line show directions. .....
This is pretty much my imagination .

RossIn space travel, coordinates are typically determined by using a system such as celestial coordinates, which locate objects in space based on their positions relative to celestial bodies. Direction is determined using navigation systems like star trackers or gyroscopes, which provide orientation references such as the positions of stars or the Earth's magnetic field. These systems help spacecraft navigate accurately through space.

Which direction do microwaves travel?
Microwaves travel in a straight line and propagate through space or materials when emitted by a source such as a microwave oven. Their direction can be altered by reflection, refraction, or absorption.
What direction does electromagnetic waves travel?
Electromagnetic waves travel in a transverse direction, which means they propagate perpendicular to the oscillating electric and magnetic fields. This allows them to travel through space at the speed of light in a straight line.
Is space a vector or scalars?
Space is a vector because it has both magnitude (size) and direction. It is commonly represented in three dimensions with x, y, and z coordinates.
Are needed to describe a vector?
To describe a vector, you need both magnitude (size or length) and direction. In a 2D plane, this could be represented as an arrow with a certain length and direction. In a 3D space, it would require three coordinates to pinpoint its position and orientation.
How can you describe position?
Position refers to the location or placement of an object or person relative to other objects or a reference point. It can be described using coordinates, such as latitude and longitude on a map, or in terms of distance and direction from a specific point or landmark. Position is essential in navigation, physics, and many other fields to determine location in space or on a surface.
