How do you do the orbital rendezvous?
For orbital rendezvous to occur, both spacecraft must be in the same orbital plane, and the phase of the orbit (the position of the spacecraft in the orbit) must be matched. For docking, the speed of the two vehicles must also be matched. The “chaser” is placed in a slightly lower orbit than the target.
How do I use Hohmann transfer?
The orbital maneuver to perform the Hohmann transfer uses two engine impulses, one to move a spacecraft onto the transfer orbit and a second to move off it….Application to interplanetary travel.

Orbital radius (AU) | 1.52 | |

from LEO | 3.6 |
What is rendezvous proximity operations?
The Aerospace Corporation defines RPO as two or more satellites in space matching their plane, altitude and phasing (rendezvous). Often, the proximity operation involves a maneuver that causes purposeful physical contact between two satellites. This subset of RPO is known as docking.
What is the first international space rendezvous?
Fifty years ago, the two-tiered NASA mission Gemini 7/6A made history by proving that two independently launched spacecraft piloted by astronauts could meet up while orbiting Earth. Humankind’s first rendezvous in space happened Dec. 15, 1965.
How do I make my KSP dock easier?
Click on your own docking port and select “control from here.” Then click on your target’s docking port and select “set as target.” That is all. Turn the camera sideways and watch the amazing spectacle of your two ships docking effortlessly.
How do you transfer fuel in KSP?
To transfer fuel you will have to dock your vessels. This can be done either using docking ports on both vessels or a “grabbing unit” aka the “claw” on one of them. You will also need to have at least one upgrade of the science facility back at the Kerbal Space Center to enable resource transfer.
How does a low thrust engine perform a Hohmann transfer orbit?
Low-thrust engines can perform an approximation of a Hohmann transfer orbit, by creating a gradual enlargement of the initial circular orbit through carefully timed engine firings. This requires a change in velocity (delta-v) that is greater than the two-impulse transfer orbit and takes longer to complete.
What is the Hohmann transfer?
The transfer itself consists of an elliptical orbit with a perigee at the inner orbit and an apogee at the outer orbit. The fundamental assumption behind the Hohmann transfer, is that there is only one body which exerts a gravitational force on the body of interest, such as a satellite.
How does orbit ratio affect Δ V for second burn?
For higher orbit ratios the Δ v required for the second burn decreases faster than the first increases.
What is the speed of geostationary transfer orbit?
Consider a geostationary transfer orbit, beginning at r 1 = 6,678 km (altitude 300 km) and ending in a geostationary orbit with r 2 = 42,164 km (altitude 35,786 km). In the smaller circular orbit the speed is 7.73 km/s; in the larger one, 3.07 km/s.
