What is the orbit to determine?

In astronomy means determining the orbit to predict the way the objects in the universe are orbital. There are several methods to perform these predictions. The initial method of determining the orbit is the simplest method and requires two measurements to find the direction and speed of the orbital body. The smallest square method is more accurate, but requires many estimates of the same orbit to create a direction, speed and orbit. The sequential processing method is the most accurate and requires many estimates of the orbit error from previous models. This method creates new orbital models that take into account several factors that cause orbit error, such as small collisions with space dust. Orbit error can cause major problems in the GPS system and need to be monitored constantly. The grounds planned for a collision are expected to be predicted with the nebomertodes of the determination of bital before the impact.

initial orbit determination was used throughout history and many astronomers were developed SamAfter all. It was used by Johannes Kepler to derive his three laws of planetary movement. The first exact model of the Orbit for the Mars planet was also developed by the initial determination of the orbit.

Od té doby, co byl poprvé vyvinut Carlem Friedrichem Gaussem v roce 1801, nahradila metoda nejmenšího čtverce použití počátečního stanovení orbity. The orbital period is a complete loop of orbit. Metoda nejmenšího čtverce ukazuje, že mezi úplnými orbitálními obdobími se vždy existují chyby, které se tvoří kvůli neznámým silám a interakcím obíhajícího těla během cesty. The initial determination of orbit does not take into account previous data. It is only the first step in the modern determination of the orbit, because the smallest square method calculates the error in orbit.

S. S.SEMBLY Method of processing is the most advantageous for computer modeling. With this method and Sherman's sentence astronomers develop orbital models using computersTo find future position, speed, direction and orbital errors with very limited data. Sherman's sentence requires another mathematical step towards the sequence method called linearization.

Complicated mathematical and extensive data needed for the use of the sequence method are often not available, so astronomers create estimates for the sequence method. This reduces the difficulty of determining the orbit, but slightly increases the orbit error. This process is called referring to the estimate of the status. Astronomers use a link to estimation and linearization of the condition only if the orbital data they study are too small to use non -linear sequence methods.
