Artificial Satellite

In the context of spaceflight, a **satellite** is an object that has been intentionally placed into orbit. These objects are called **artificial satellites** to distinguish them from natural satellites such as Earth's Moon.

## Chronology

As a result of its transfer to the New World, all satellites owned by Japan were lost, making some technologies such as the GPS unusable.

However, satellites are a necessity for a modern society, and the hostile situation of the New World makes the deployment of satellites an urgency, especially for the JSDF. And since Japan is the only country in the New World that possess space technology, they have to launch large number of satellites alone.

As of April 25, 1642 (3 years after the transfer of Japan), it has been confirmed that Japan had launch and deployed 4 reconnaissance satellites, but other satellites are still unconfirmed

On Earth, Japan deployed 2 types of satellites to monitor North Korea. An optical and an radar. The optical satellite have better image resolution but the radar can see through clouds, that's why they are deployed on pairs. Camera technology is improving year by year, so the resolution is getting higher and higher. In the past, a unit of 1 meter was the best, but now it is said that the resolution is 50 to 30 cm or less, and some of them are about 10 cm. The resolution of radar is about one-fifth to one-tenth that of optical satellites, but recent ones have a resolution of 1 meter or less. Due to budget limitations Japan is probably bellow great powers like USA, Russia and China, but still among the top countries.

Future plans includes the establishment of the Japanese GPS for civilian and military application. It is targeted for utilization within 3 years (5 years in the Web Novel) after the Japanese-Parpaldian War. In addition to this, Japan is planning to establish a 24/7 surveillance system using reconnaissance satellites that acts as an early warning system, in preparation for the return of the Ravernal Empire which is confirmed to have ICBM technology and have no qualms of using it indiscriminately.

It is stated in the Light Novel that the New World is unfavorable for launching satellites than Earth and all concerned Japanese agencies are forced to modify their rocket, the H-IIB and all of their calculations for a successful launch.

### Thrust-to-Weight Ratio problem

The New World is confirmed to be larger than Earth, and this make that there is a significant decrease in the Thrust-to-Weight Ratio. The concerned Japanese agencies are forced to make new calculations and modify the H-IIB rockets in rush in order to make the launch successful. With this, it is expected to make Japan a new model of launch vehicles to avoid these problems in the future. It is target to use 3 years after the Japan-Parpaldia War.

## Service History

First used during the Japanese-Parpaldian War, the Japanese diplomat Yanagida showed photos captured by the then-recently launched satellites to the Mu ambassador about asking permission to use the airport Mu built in Altaras Kingdom. This shocked the Mu ambassador. The same reaction also happened during the meeting of the HME officials when they presented the map of the world that acquired during their research in Japan because it showed the location of the Gra Valkas Empire. It made Emperor Mirishial VIII even more interested in Japan as they had something that is similar to the Mystar of the Ravernal Empire.

During the Japanese-Parpaldian War, it located the naval base of the Parpaldia Empire along with the images from the RF-4E.

In addition, it discovered that the Annonrial Empire is a very advanced magic-based civilization and is more than what they show to the New World. It also reveals magic battleships and a national power that can rival the Holy Mirishial Empire.

In Nihonkoku Shoukan Gaiden 2, it revealed traces of civilized fire in the Grameus Continent, a continent thought to be a No Man's Land. Later the source of those fire found out to be the Esperanto Kingdom, a kingdom found by the Interracial Alliance that went to Grameus 10,000 years ago to destroy the then-slumbering Demon Lord Nosgorath. After the C-2 crash, Japan launched a satellite that is intended to monitor solar weather.

During the Great Naval Battle of Japan, Prime Minister Yomoya expressed the urgency to launch more satellites since the current 4 satellites of Japan can't monitor the GVE Great Fleet's movement in real time situation.
