There are lots of ways of determining where you are in space. You can use RADAR ground stations to track you, or you can use the positions of various stars. I'm not sure why you have such a hard time understanding that.
Hm, you are orbiting in space turning at high speed all the time and you use RADAR ground stations to track you and stars for position, so you know when to blast away to the Moon or Mars.
But this is what we do on seagoing ships to go from one port to another, but we are not blasting away into space.
I think you mix things up. Navigation at sea is different from human space travel. At sea the position of the ports on Earth are fixed and your speed is quite low and you can change course quite easy to adjust your trajectory. In space the ports are not fixed but orbiting all the time so you have to ensure they are there when you arrive. Different ball game.
Have you ever shot skeet? Hitting a moving target is tricky, but not impossible. The distances involved in going to the moon or Mars means that you have plenty of time en route to make any necessary course corrections. It's not as if the wind or currents will take you off course or anything.
I have done military service in the Royal Swedish Navy 1965/70 including a lot of training shooting with various weapons. Objective was to wipe out the enemy soldiers in front of me or to kill a single enemy with a shot between his/her eyes or ... my weapon ... to blow up an enemy ship with a sea mine killing thousands and sinking plenty enemy goods. I loved it!
The targets were always moving ... but not very fast ... but there was no time to correct anything. If I didn't shoot first, the risk was that I was shot. But I was never afraid. If you are in the military biz killing is part of it. The reward is being admired by our female helpers - the lottas.
Have you ever done anything military? Training killing people?
But you are off topic. Topic is my Challenge - a peaceful manned trip to Mars and Moon. Do not change the subject with your nonsense. Skeet! Weekend fun!
So poor Heiwa can not figure out how to calculate a rendezvous between two objects. Is the math too hard for you? It just involves distance, velocity and time which should be rather easy for an engineer to calculate.
So you were in the Kustjδgarna? I am guessing your memory is failing you again and your service and training did not focus on ground combat. You maybe went to a firing range once to twice a year. My guess the focus would have been only on side arms.
Are you so disappointed in your life that you got to make things up and greatly embellish your past?
How about telling me the requirements for getting evidence you can afford to pay if someone wins your "challenge"?
Is e-mailing you for the information enough? Do I have to call, show up at your lavish apartment, mail you something?
I would review Keplers laws again. You seem to fail to understand what they say. Space travel is orbits and Kepler's laws are about how all orbits work. With those laws a person can determine the velocity needed to get into a certain orbit and what happens if you change the velocity while in a certain orbit.
I would also suggest you review what delta-v is and why it is so important when it comes to space travel.
Then learn a little something about celestial navigation, radar, radio telemetry, doppler effect, measuring angles, geometry, trigonometry and how they relate to navigation and getting something's fix.
