I am not doing it for real satellites. Just a simulation.. But for simulation i need to get the circular motion and possible collision in animation view. Thats the reason i am using formulas. for example in http://www.science-animations.com/support-files/gravitasieplaneteb.swf they have done a simulation. it is not for real satellites but it follows basic physics rules(formulas)

Thank you for the nice explanation. I am considering a real system. I want to develop a simple basic simulator similar to this url http://www.science-animations.com/su...ieplaneteb.swf. That is, monitoring a satellite to avoid collision with nearby satellites/debris using basic physics formula. What way can this be handled such that it looks realistic(using physics formula) but need not be accurate?

Ok. Thank you for the reply. I am asuming that the circular orbits are perpendicular to each other(one vertical and other horizontal to earth). correct me if am wrong.. I thought that as the satellites revolve, there is change of velocity and there are chances of the 2 satellites coliding if not monitored.

Ok. Thanks a lot.. Is there any other way to check collision of 2 satellites known their initial positions, masses and initial velocity? I am trying to simulate something similar to this url http://www.science-animations.com/support-files/gravitasieplaneteb.swf.

Thank you for the reply. I am not able to understand the other forces to be included. "forgetting to include force from the primary into the integration". It would be of great help if you could elaborate on this.(as I know little physics and trying to get this working!!)

1)The satellites are revolving round the earth. I need to control the satellite 1 based on the force exerted on it by satellite 2 so that satellite 1 does not collide with satellite2. 2)The 2 satellites are in different orbits. same altitude but one orbit is vertical to the earth and other horizontal. so the satellites can collide at the intersection points.

I want to write program to find the distance between two artificial satellites in space every 't' seconds. My initial inputs are initial velocity, masses , radii, position(x,y coordinates) of both the satellites. Then using Pythagoras theorem I can find the initial distance between the 2 satellites. Then I calculate the force exerted by Satellite 1 on Satellite 2. Using Force/mass i need to find the acceleration and double integrate it to get distance between the 2 satellites. The 2 satellites are continuously revolving in 2 different circular orbit(such that they may collide). I have tried using linear acceleration = Net force/massOfSat1; angular acceleration = linear acceleration/radiusOfSat1; This formula does not give a valid distance as the distance keeps on increasing but I expect that the distance increase and decrease as it is circular motion and the satellites can come near or go far as well . I feel that I am going wrong in using a suitable formula for acceleration. Your help and suggestions will be greatly appreciated.
