Two angles and a distance are meaningless unless you know the origin point. What you are referring to is charting a course from your location to a known point. So, to ID a location, what you want is three coordinates in X, Y, and Z, or have it as angle 1, angle 2, and distance from a common reference point (nearest star for items in orbit around a star, the main planet for items that belong to a planetary system. Of course, with orbits, those will change over time as well. This means you need to also know the orbit of the object in the system. If that object is in orbit around the star, it's just one orbit you need to worry about. If it's in orbit around a planet in the system, you need to know the orbit of the planet, and the object around the planet if you want to get to it on one jump. This mean that if you want to get to a particular place, in one jump, you need to know everything about that system (assuming semi-real orbital mechanics are implemented).
Example, you want to get to the Big Benny's broadcast location in Yela, and you are starting from ArcCorp.
First, you need to know where Crusader is in relation to ArcCorp. Then where Yela is in relation to Crusader, then were the Big Benny's vending machine is in it's orbit of Yela. As you can see, it's getting very complex.
Now, a better method would be to use a "beacon" system. Hopefully, they will allow private beacons that are shared only by Orgs or by groups of people. This would allow someone to find a location, drop a beacon that will float along with the location in question (share orbital space) that only responds to a valid code, then does a quick encoded broadcast that allows you to find and then QD to that location directly as long as you have an unobstructed path.
Also, considering the distances involved, trying to find a specific location and QD to it by referencing a distance from a star or even a planet will be very difficult to attempt. Getting within 20 miles of a specific location without a beacon to lead you in when you are talking millions of miles will be close to impossible. The Earth is 93 million miles from the sun (about 150 Million Kilometers) with both values being rounded a bit. Getting within 20 miles will be a the noise level for most distances within a star system.
Now, that's just my 2 credit's worth, but I am not sure the system...as initially stated...will work. Maybe there is something that can work, but it might require some find tuning and a lot of math behind it.
