Abstract
This paper presents a globe coverage of constellation satellite in one revisit and the regional coverage at defined latitude. This constellation seems to be very close to optimal under the maximum revisit time comparing to the results in other papers. They are produced easily by using tables and data achievements. These satellites are fully connected by crosslinks sweeping the Earth. This model is more optimal comparing to the conventional constellations that distribute satellites evenly in the space. Since satellites on the LEO orbit are side by side, in most cases, they can maintain communication continuously. This special feature allows all satellites in the constellation connecting ground at any time when a satellite is available to the stations. Length of the crosslink is allowed to reject location connection or real-time data transmission. For example, six satellites in the constellation cover the whole Earth within one revisit time and all the data are collected by two Earth stations for keeping continuous coverage. Thus, the adjacent satellites may be more efficient and provide more coverage.
Highlights
Studies have shown that Walker constellations with given (T/P/F) parameters are optimal for global comprehensive coverage
The results indicate that the efficiency of polar COB constellations is better, there may be certain conditions that the continuous coverage of crosslink goes towards global returns
In order to compare the performance of GA and Walker constellations mentioned above, let us take the examples of optimizing MRT values in Reference [3]
Summary
Studies have shown that Walker constellations with given (T/P/F) parameters are optimal for global comprehensive coverage. One advantage of this configuration is that the latitude and longitude coverage is done at the same time and there is user access to all satellites at one time) is the second method that neighboring satellites are arranged with overlap coverage. Another aspect that will be investigated is close proximity of satellites that makes time to paint the ground In this analysis, the establishment and optimization of two constellations COF and COB will be discussed. This makes it an ideal global cover across the globe
