Chapter 1374 GPS Satellite Guidance Technology

Back at the Observatory, the meals delivered from the base just arrived.Everyone immediately ate a little bit, and then took the time to rest.However, Jiang Chen did not take a break, but began to discuss the next test work with a group of testers.In terms of itself, if the normal test procedure is followed, this kind of test work will often last for a long time.But now, because of the arrival of Director Song and the others, in order to take care of them, the time of the whole test was arranged very tightly, which brought a lot of pressure.And now he wants to use this little time to sort out the next test work in detail to ensure that the next work can be carried out smoothly.

At two o'clock in the afternoon, the testing work continued.The first is to test the guided bomb before. Although the guided bomb is to be tested this time, it is divided into different models.There are laser irradiation guidance, TV image guidance, inertial guidance, infrared guidance and satellite positioning guidance.Although there is no satellite guidance equipment in China, in order to test this technology, the R&D personnel chose the old American GPS satellite navigation technology for navigation and positioning.Of course, what they use is only public civilian signals, and there is still a certain gap between the military signals used by the old US troops.

"Xiao Jiang, is the guided bomb going to be tested next?" Director Song sat down and said with a smile.

Jiang Chen nodded and said, "Yes, the first thing we want to test is this guided bomb. If time permits, we will also test the gliding guided bomb today."

"Oh, that's it, then I'll just wait and see." Director Song said with a smile.

Jiang Chen smiled and nodded at Chang Qing, "Get ready to start!"

"Yes!" Chang Qing understood, then grabbed the transmitter and said, "Hongyan No. [-], here is yellow sand, here is yellow sand."

"This is Hongyan No. [-], Huangsha, please tell me."

"No. [-] ammunition test, you can start. Repeat, you can start!"

"Huang Sha received it, and the No. [-] ammunition test has officially begun."

"Xiao Jiang, tell us about the content of this test." Director Song said to Jiang Chen with a smile.

Okay, Jiang Chen nodded and said to everyone: "This time, we are mainly testing guided bombs with four guidance technologies. The first two are the laser irradiation guidance and TV image guidance mentioned earlier. The guidance methods all rely on the guidance of the optical detection and targeting pod. The latter two do not rely on the optical detection and targeting pod. The first is infrared tracking guidance, which uses infrared guidance technology to guide the bomb , used to attack ground targets. The other is GPS satellite guidance technology, which uses GPS satellite positioning system for guidance.”

"GPS satellite guidance, is this the old American satellite positioning system?" Deputy Chief Zhao responded.

Jiang Chen nodded and said: "That's right, it's this positioning system, and the positioning guidance technology in this area is also the cutting-edge technology in the world. We also want to conduct related tests. However, the system we use in this place It’s just their civilian signal, and we don’t use the military signal that is actually used for their weapon guidance, so there may be some deficiencies in accuracy.”

Zhao Vice #长 nodded and asked Jiang Chen: "I remember that you launched two navigation satellites a while ago, why, can't you?"

Hehe, Jiang Chen shook his head with a smile and said: "We have launched two navigation satellites, but they are only in the initial testing stage, and the technology is not mature enough. Besides, these are just two satellites. The service window and positioning accuracy are not enough for further application. It can only be used as an experimental platform to explore related technologies. And a GPS satellite positioning system like this one is developed by 24 or more navigation satellites in orbit. The global navigation network formed. So in this respect, we still have a big gap. So we use GPS satellite guidance technology this time to verify the feasibility of this technology and related experimental parameters, and do a good job for our follow-up further experiments. Prepare."

Well, everyone nodded after listening.At this time, the voice of Hongyan No. [-] came from the radio: "Huangsha, Huangsha, this is Hongyan No. [-]."

"This is Huangsha, Hongyan No. [-], please tell me."

"I'm about to reach the sky above the target area, requesting permission to attack!"

Chang Qing looked at Jiang Chen, and with Jiang Chen's nod, Chang Qing replied: "Hongyan No. [-], I am Huang Sha, and I approve the attack according to the predetermined plan."

"Hongyan No. [-] received it, and launched an attack according to the predetermined plan!"

"Here we come!" Someone shouted, and then everyone quickly picked up the binoculars and began to observe.I saw an An-12 transport plane flying towards the shooting range in the distance.As time progressed, the plane got closer and closer. Suddenly, when it was about to reach the sky above the target, several bombs were dropped from the wing pylons of the transport plane, and then quickly fell to the ground.

boom!boom!Boom! After seven or eight seconds, there were bursts of explosions, and then a burst of smoke rose.Because of the cover of smoke and dust, Jiang Chen and the others could not see the result of the attack for the time being.But Hongyan No. [-], which was circling in the sky, had good news:
"Huangsha, Huangsha, this is Hongyan No. [-]. Now report the battle situation. Two laser-guided bombs and two TV-guided bombs have all hit the targets, and the damage effect is good."

"Yeah,,," the crowd applauded and cheered.

"This is Huangsha, Hongyan No. [-], continue to attack!" Chang Qing held back his excitement and continued to order.

"Hongyan No. [-] received it, continue to attack!"

Then Hongyan No. 20 dropped bombs several times, dropping both infrared-guided bombs and GPS-guided bombs, but the effect was not as good as the previous two.The first is infrared guidance. To put it bluntly, it is to find a heat source to attack.But it may be due to the weather, or it may be a malfunction of the bomb itself, so this time the two bombs using infrared guidance technology did not hit the intended target.In addition, there are GPS-guided bombs. This time, the two bombs using this GPS-guided technology also deviated far from the target, and both exploded at a place more than [-] meters away from the target.It can be seen that the accuracy of civilian signals during this period is still very limited, far inferior to the accuracy of military signals.However, it can also be seen that GPS technology in this period still has a long way to go compared with later generations, and this just gave Jiang Chen confidence.Because although in this respect, compared with others, they are still far behind.But in Jiang Chen's view, this gap is not so far away.As long as you work hard, at least the current version of the Beidou satellite navigation system will never be inferior to GPS in the near future.
