In October 1957, the world's first artificial satellite was launched by the former Soviet Union, successfully opening up a new era of human beings entering a space science and technology. At the same time, this kind of science and technology that moves radio navigation sources from ground navigation towers to satellites and uses satellites to position and navigation not only caused a sensation around the world, but also attracted high attention from various world power departments and accelerated the development of satellites.

The Doppler Navigation System (DPL), the first generation of satellite positioning system in the United States, was developed by American scientist Middle Kirit in the 1960s.

However, this positioning system has a disadvantage, which is that it cannot monitor the movement of aircraft and rockets, and can only monitor relatively large ground targets.

So if Chen Yanlong’s previous smartphone redemption system did not have the authority to redeem more advanced positioning systems and satellites, then Chen Yanlong would definitely not have redeemed this Doppler navigation system.

Instead, it is exchanged for the US GPS satellite navigation and positioning system, Russia's GLONASS satellite navigation and positioning system, and Europe's Galileo satellite navigation and positioning system, which are famous satellite positioning systems.

Because the GPS satellite navigation and positioning system in the United States has 28 satellites (4 of which are spare), while the GLONASS satellite navigation and positioning system in Russia has 21 satellites, and 3 are spare. The Galileo satellite navigation and positioning system in Europe has 27 working satellites, and 3 of them are spare.

But Chen Yanlong now has only Doppler navigation system (5-7). If you compare this, you can know the strength between them.

After Chen Yanlong sent telegrams to Keseling and Denitz, he immediately brought his guards to Alfred Jodel, director of the Operations Bureau of the Supreme Command of the German Army, General Zeitzler, Chief of Staff, Goebbels, German Propaganda Minister, German Minister of Defense Keitel, and the commander-in-chief of the Reserve. He went to the Sixth Institute of the Ministry of Defense that Chen Yanlong secretly established, and also established a space laboratory called Jinlilai Satellite Launch Center.

There, German rocket experts Weiner von Braun, Hermann Obert, as well as Lieutenant Colonel Becker, the director of the German Army's Quartermaster, and Huberts Straghold, the "father of aerospace medicine", led a large number of scientists and astronauts, commanders, pilots, ship engineers and flight engineers, mission experts and payload experts and other satellite staff were waiting for Chen Yanlong's arrival.

"Have our satellites been launched?"

As soon as he arrived, Chen Yanlong immediately asked German rocket expert Weiner von Braun.

"Yes! Head of State! Two Doppler navigation systems have been launched, and all other equipment have been installed!"

Von Braun immediately agreed respectfully.

"How is the personnel training? Especially those equipment are familiar with how to operate?"

Chen Yanlong continued to ask.

And under the leadership of von Braun, a large group of them entered the Kinley Satellite Launch Center for a visit.

As soon as he entered this launch center, all the officers beside Chen Yanlong were shocked and stunned, as if he was in a dream, and it was not real at all.

"What is this place! The equipment here is very advanced!"

"I have never seen such advanced equipment before, why have I never heard of the head of state building such a place!"

German Defense Minister Keitel, who was beside Chen Yanlong, was the first to stare at the shocked eyes, staring at all the advanced satellite equipment around him with wide eyes, and said in shock.

As for Alfred Yodel, director of the Operations Bureau of the Supreme Command, General Zeitzler, Chief of Staff, and Goebbels, the German Propaganda Minister; and Paul Haussel, the commander-in-chief of the Reserve, a large group of officers had not yet reacted from the shock for a while.

"All personnel, including the aerospace personnel, have already trained according to the instructions of the head of state, and have been training for more than 12 hours a day."

"So many people are gradually familiar with operating the advanced equipment here, but it will take a long time to be very proficient, because these aerospace technology training is the first time in human history, and no one has ever tried it before, so I hope the Head of State can give us more time!"
