Xing Baohua understood. Indeed, sometimes it's easier to communicate over the phone. A face-to-face meeting is part of showing sincerity. By observing facial expressions and body language, one can gain a comprehensive understanding of a person's sincerity or hypocrisy.
After seeing Captain Han off, Xing Baohua began to carefully examine the data he had retrieved from Chief Engineer Gao.
He was thinking about the weight of the CPU, motherboard, memory, etc. The core component, in essence, is a super-powerful server.
The motherboard has many integrated chips, and following the Iridium approach, it's practically useless. It cost a lot of money, the equipment is outdated, and even now, let alone ten years of use, it will lose most of its functions after five years. The only thing it can still use is to make a satellite phone or something.
Xing Baohua's proposed civilian satellite design might draw inspiration from a small part of the Iridium satellite, but its main structure will be developed in-house. It needs ample memory to ensure smooth network connectivity and requires a large number of memory addresses.
For a single star, at least 200,000 connection ports need to be set up to avoid lag.
The network speed cannot be designed according to the 2G speed; we need to think about 3G. However, the technology cannot be improved to the speed of 3G, so we need to redevelop the firmware.
This is a technology that will be advanced ten years from now. When this technology becomes widespread, the stars in the sky will have reached the end of their lifespan.
Wouldn't that be too wasteful? So, how about using 2G technology to create 2.5G?
This is a viable option. It involves upgrading 2G technology, which can be done without using it initially. After a certain period, the driver in the old firmware can be upgraded via software.
The hardware cannot be upgraded, but the firmware can be changed via remote data.
Just like we're using Windows 11 now, could mainstream XP machines from over a decade ago also use Windows 11?
Theoretically it's possible, but in practice it's just so-so.
The speed won't be too fast, so you won't notice the lag to some extent. However, if you use current Win11-era programs, you'll see lag, slowdowns, and even crashes or blue screens.
Incompatible!
There are also those TV boxes. No matter which operator you use, they will give you a TV box, and you have to pay a deposit of 100 yuan for it.
As times have changed, that thing has become obsolete. What to do? Modify the system and upgrade the firmware.
It can be transformed into a home karaoke room where you can watch TV, play games, and sing karaoke.
This thing is basically an emulator installed on the existing system. It uses the emulator to achieve multiple functions.
Flashing a device carries risks; only those with strong hands-on skills and a good understanding of the process can do it.
Flashing a device requires disassembling it and finding the shorting point. The shorting point requires an engineering cable, which is a cable with a built-in port driver. When you short it, it will show the required port, and you need to start flashing data from this port.
Normally, data cables won't show up; this is called a hidden port.
Firmware is a system package that includes a lot of pre-written software. If you don't follow the steps, flashing the firmware will brick your device.
Once the bricks stop working, the equipment is useless.
These are the same operations as flashing the operating system on mobile phones back in the day. Especially with BlackBerry and Motorola, people would flash their phones all the time, creating all sorts of versions, from streamlined to advanced, from official to downgraded.
Apple does the same thing, just with a different name: jailbreaking.
Why do so many people persist in flashing ROMs? Especially those who are only half-baked, partly for fun, and partly to learn some technical skills.
You haven't even figured out how to root your device, and you want to flash it for fun? You'll only end up with the same old thing.
In the end, I still want to revert to the official version.
Upgrading satellite firmware is basically just patching some things; the hardware is still the same. In other words, it's optimizing the system.
To achieve ideal data on the existing hardware, it's a software matter, involving optimization in various aspects from the system to drivers, which requires a high level of technical expertise.
If you want to flash firmware on a satellite that's already in space, there won't be enough data cables to cut from space anymore, so remote control is required.
Xing Baohua's team is capable of doing this, but this method of operation is prone to leaving loopholes.
Another issue is the security measures for encrypted data. Currently, these are all limited by equipment, so they are all roughly the same in terms of cracking.
Xing Baohua recalled seeing a communications soldier being interviewed who said, "Can the enemy crack our military's encryption?"
The communications soldier, with a mocking expression, said that the other party was researching how to crack encryption methods and would be more suited to researching time machines.
The words were arrogant, but half were true and half were exaggerated.
The truth is, it would take the enemy several years or even decades to crack it, a process during which we would have already updated our encryption system several generations ago.
The enemy spent so much time cracking it, but it was completely useless.
Cracking requires a short process, just like when you enter a dynamic password, it expires after 60 seconds. If you want to crack it, you need to crack it within 60 seconds. Is it still useful after two days?
Exaggeration is meant to scare the other party, and it's even said to 99% of people who don't understand. Those who truly understand the technology won't come out to prove it.
As long as the device can be cracked quickly enough, it is still achievable.
But it's unknown how many years it will take to build such a powerful device, so talking about it is pointless.
If the enemy dares to prove they can crack it in a short time, it means they have such a device.
This kind of reminder is so helpful. I know you've already done it, so I'll change it, okay?
Xing Baohua was drawing when he had nothing to do. He would first come up with a direction and then adjust the structural diagram.
