“…All corrections complete… …Now running the final self-diagnosis…”
“The control AI has cleared all check items. 440 seconds remaining until the completion of the satellite self-diagnosis program.”
While listening to reports from Akane and Olive, Eve gazed at the satellite orbital map.
The satellite group that constitutes the Ground Positioning System, launched the other day, was finally about to begin operation.
All of these GPS satellites are set in geostationary orbit, that is, orbiting above the equator in synchronization with the planet’s rotation. Each satellite maintains a communicable distance from each other while emitting accurate position information signals.
The objective of this mission is to ensure that at least four signals can be received from any location on the planet.
Apart from the poles, the accuracy near the equator is within a few centimeters. In the future, by adding satellites to quasi-zenith orbits, global accuracy can be ensured.
“…Diagnosis complete…”
“Self-diagnosis of all GPS satellites completed. All functions are green. The control AI has sent permission to transmit GPS signals.”
“…Signal received… …No problems…”
And all of the GPS satellites made by
Weak GPS signals rained down from above the equator to the entire globe.
Of course, the signal strength is suppressed to the limit.
Even with considerably sensitive detection, it would only be perceived as a few more bright stars in the sky.
“You said the signal strength can be adjusted, right?”
“Yes. The strength can be temporarily increased when operating in areas where signal strength is needed. We can respond according to the situation.”
For example, in a forest covered with trees. If the signal is blocked by thick trunks and weak radio waves cannot cope, it may be possible to use it by temporarily sending a stronger signal.
“Alright, alright. This will prevent us from getting lost on the ground. What’s next…?”
“Laser communication satellites are being deployed sequentially. We are building an environment where real-time communication can be maintained in the assumed activity area.”
“…We’re also increasing the number of surveillance satellites and observation satellites…”
Fully utilizing the expanded launch site, artificial satellites are being launched one after another.
These automated machine groups, manufactured with the best of
“At least, no obstacles that would hinder our activities have been found in the satellite orbit. Satellite deployment will continue until the planned number of units is reached.”
“Thank you, ＜Ringo＞. For now, that’s going well. …What about the other continents?”
“Yes! Onee-sama! Asahi will report!”
When Eve brought up the next topic, Asahi raised her hand with a flourish and stood up energetically.
At the same time, a map of the planet was projected into the air.
It was a spherical map to accurately display the distances of each location.
“We are releasing observation buoys into the surrounding oceans! We are having the surveillance satellites take regular pictures to create ocean current maps! Well, we’ve roughly figured it out, so I think it’s about time to send out the battleships!”
“Hmm… Compared to before, the number of shooting opportunities has increased dramatically, hasn’t it?”
“Satellite images? Hmm, that’s right. I think it’s probably increased by about 10,000 times.”
“Are there any traces of marine Threat Creatures?”
“Ah.”
In response to Eve’s question, Asahi displayed several images in rapid succession. It seemed she had pulled them from storage.
“Honestly, there’s nothing that clearly identifies them yet! But there are a few suspicious ones… around here!”
What was displayed was an isolated island floating on the sea.
Surrounded by cliffs, with gentle hills, and entirely covered with plants.
At first glance, it looked like an ordinary island.
“This island is clearly moving… At first, I thought it was a floating island, but there are a lot of rocks visible, and it sometimes goes against the ocean current! So, the conclusion is that it’s probably a huge turtle or something!”
“A turtle…?”
A giant creature, so large that it could be mistaken for an island, freely moving around the sea.
That was the conclusion that Asahi had reached after continuing surveillance.
“Well, it’s almost on the opposite side from here, so we’re just keeping an eye on it! We’ve found quite a few Threat Creatures like this island!”
It seems that several similar islands have been found in the archipelago around the opposite side of the planet from where
“Geez… This planet is still dangerous…”
“I agree with that! Also, marine Threat Creatures cannot be observed from satellite images unless they float on the surface of the sea! There are a few images with huge whale-like shadows, but that’s it! By the way, the estimated total length was 850m!”
“850m…?”
“That’s just the shadow that’s visible! It might be even bigger!”
At least 850m in a whale-like shape. No matter how easy it is for marine life to grow large, it’s a size that’s hard to believe.
It is far larger than the Fortress
“It’s bigger than the ＜Odin＞-class being built! Well, this is also quite far from
“So we need to be on alert… Well, the more satellites we have, the easier it will be to be on alert, right?”
“Yes, Onee-sama! Olive Onee-sama has calculated that! We will be able to monitor the entire globe 24 hours a day!”
“…Buoy.”
Eve approached Olive, who turned around and made a “buoy” shape with her right hand to show off, and stroked her head. Olive puffed air out of her nose, looking satisfied.
Eve was also satisfied to see her younger sister like that.
“The resolution during surveillance and the target frequency band will be greatly improved, so I think we will be able to proceed with the selection of target continents! In particular, we will be able to continuously monitor infrared at night, making it easier to infer the level of civilization!”
“The construction of the Great Battleship is also going smoothly. According to the schedule, hmm, 1,150 hours left…?”
“Approximately 48 days, Onee-sama!”
“Oh, about that much. We can finally increase our intercontinental bases…”
A large-scale dispatch fleet centered on the Great Battleship. The schedule for its departure has been firmly established, and the process is progressing smoothly.
Construction of a surveillance system, operation of GPS, and laying of a global communication network.
Since everything relies on satellites, everything depended on whether the satellite orbit could be used safely.
And so far, it seems to be progressing smoothly.
Whether this is because the concealment measures are working well, or whether there really are no threats in the satellite orbit is unknown.
“We are proceeding with the selection of the next landing point! We will narrow down some candidates and measure the degree of threat in the surrounding area! We plan to have the analysis completed in about 30 days!”
“So we can decide where to advance around that time.”
“Yes, Onee-sama! We plan to narrow down the candidates to 2-3! From there, we will consider the merits and demerits and have Onee-sama make the decision!”
Selecting the optimal landing point from a large amount of information would be easy for AIs like Asahi.
But the Commander is Eve, and she is human (probably).
Humans have emotions and may choose options that are not the optimal solution.
And the AIs of
Of course, if they wanted to, they could observe all of her constituent materials and construct a precise simulation model.
However, the Superintelligence of
They judged that they could not properly process the raison d’être of serving Eve.
Therefore, from now on, they will continue to faithfully carry out the imperfect instructions given by Eve.
Ringo-chan and the others are also independent Sentient Entities with limited resources.
As long as they use arithmetic units that require reward systems, they must continue to deal with desires.
