1
00:00:00,000 --> 00:00:02,240
為什麼中國要急著搞自己的星鏈

2
00:00:02,240 --> 00:00:04,440
很多人以為那只是上網工具

3
00:00:04,440 --> 00:00:06,280
其實它背後的意義

4
00:00:06,280 --> 00:00:07,600
很多人都想簡單了

5
00:00:07,600 --> 00:00:08,700
此前我們講過

6
00:00:08,700 --> 00:00:10,860
朱雀三號可回收火箭時提到過

7
00:00:10,860 --> 00:00:13,400
中國現在全力發展可回收火箭

8
00:00:13,400 --> 00:00:15,180
不只是爲了商業航天

9
00:00:15,180 --> 00:00:16,980
包括我們自己的星鏈計劃

10
00:00:16,980 --> 00:00:19,220
也就是千帆星座項目

11
00:00:19,220 --> 00:00:20,960
也在排隊等著推進

12
00:00:20,960 --> 00:00:21,660
實際上

13
00:00:21,660 --> 00:00:24,000
今年年初千帆星座項目

14
00:00:24,000 --> 00:00:27,860
就已經向全國商業航天企業公開招標

15
00:00:27,860 --> 00:00:31,060
這也是為什麼今年多家民用航空企業

16
00:00:31,060 --> 00:00:34,720
集中發展可回收火箭的一個重要的推動因素

17
00:00:34,720 --> 00:00:35,680
簡單來說

18
00:00:35,680 --> 00:00:38,440
千帆星座是一項龐大的工程

19
00:00:38,440 --> 00:00:39,280
未來幾年

20
00:00:39,280 --> 00:00:41,720
中國計劃發射上千顆衛星

21
00:00:41,720 --> 00:00:43,360
在近地軌道上

22
00:00:43,360 --> 00:00:45,640
鋪出一張巨大的通信網

23
00:00:45,640 --> 00:00:48,980
它的目標是打造中國版的星鏈

24
00:00:48,980 --> 00:00:51,739
構建我們自己的全球互聯網系統

25
00:00:51,739 --> 00:00:52,519
那問題來了

26
00:00:52,519 --> 00:00:54,660
為什麼我們現在這麼急呢

27
00:00:54,660 --> 00:00:56,860
這就要從星鏈本身來談起了

28
00:00:56,860 --> 00:00:57,600
過去

29
00:00:57,600 --> 00:00:58,880
很多人以為

30
00:00:58,880 --> 00:01:01,060
星鏈只是馬斯克的一個商業項目

31
00:01:01,060 --> 00:01:04,260
是個高價且信號號不穩定的衛星上網服務

32
00:01:04,260 --> 00:01:05,660
但在俄烏戰爭之後

33
00:01:05,660 --> 00:01:08,600
星鏈的真正威力被世界看到了

34
00:01:08,600 --> 00:01:11,220
當烏克蘭的地面通信被炸斷時

35
00:01:11,220 --> 00:01:13,340
星鏈衛星立刻頂上

36
00:01:13,340 --> 00:01:16,160
給烏軍提供了持續的網路服務

37
00:01:16,160 --> 00:01:17,660
俄軍想干擾

38
00:01:17,660 --> 00:01:19,560
卻發現根本干擾不了

39
00:01:19,560 --> 00:01:20,060
結果

40
00:01:20,060 --> 00:01:22,520
烏軍能隨時傳回前線影象

41
00:01:22,520 --> 00:01:24,100
協調無人機攻擊

42
00:01:24,100 --> 00:01:26,720
而俄軍在沒有實時網路的情況下

43
00:01:26,720 --> 00:01:28,840
信息傳輸慢半拍

44
00:01:28,840 --> 00:01:31,080
戰場態勢一度被壓制

45
00:01:31,080 --> 00:01:31,600
可以說

46
00:01:31,600 --> 00:01:35,080
俄軍雖然擁有裝備與兵力的壓制

47
00:01:35,080 --> 00:01:37,820
可幾年下來遲遲打不開局面

48
00:01:37,820 --> 00:01:41,140
其實星鏈在背後起了很大的作用

49
00:01:41,140 --> 00:01:42,260
從那一刻開始

50
00:01:42,260 --> 00:01:44,080
全世界都明白了一件事

51
00:01:44,080 --> 00:01:46,300
通信站已經延伸到了太空

52
00:01:46,300 --> 00:01:48,200
我們日常使用的網路

53
00:01:48,200 --> 00:01:49,940
都是依賴地面設施

54
00:01:49,940 --> 00:01:51,880
電腦網路靠光纖

55
00:01:51,880 --> 00:01:54,200
手機和WiFi靠信號塔

56
00:01:54,200 --> 00:01:56,440
但只要離開信號覆蓋範圍

57
00:01:56,440 --> 00:01:56,700


58
00:01:56,700 --> 00:01:57,540
比如深山

59
00:01:57,540 --> 00:01:58,440
沙漠

60
00:01:58,440 --> 00:01:59,320
海上

61
00:01:59,320 --> 00:02:00,000
極地

62
00:02:00,000 --> 00:02:02,280
手機立刻就會變成擺設

63
00:02:02,280 --> 00:02:03,900
而低軌衛星通信

64
00:02:03,900 --> 00:02:05,660
就是爲了解決這個問題

65
00:02:05,660 --> 00:02:07,000
它的原理很簡單

66
00:02:07,000 --> 00:02:08,940
只要天上衛星足夠多

67
00:02:08,940 --> 00:02:10,920
就能實現無縫覆蓋

68
00:02:10,920 --> 00:02:12,040
無論你在高空

69
00:02:12,040 --> 00:02:12,840
海上

70
00:02:12,840 --> 00:02:13,600
還是沙漠

71
00:02:13,600 --> 00:02:14,780
都能連上網

72
00:02:14,780 --> 00:02:16,160
尤其是未來5G

73
00:02:16,160 --> 00:02:17,240
6G時代

74
00:02:17,240 --> 00:02:19,080
網路速度越來越快

75
00:02:19,080 --> 00:02:20,740
延遲要求越來越低

76
00:02:20,740 --> 00:02:23,020
而傳統信號塔功率有限

77
00:02:23,020 --> 00:02:24,160
覆蓋範圍小

78
00:02:24,160 --> 00:02:26,680
低軌衛星正好能補上這個短板

79
00:02:26,700 --> 00:02:29,399
比如臺灣這樣的島嶼地區和島嶼環境

80
00:02:29,399 --> 00:02:31,579
雖然無線網路密度很高

81
00:02:31,579 --> 00:02:33,899
但它最大的風險不在地面

82
00:02:33,899 --> 00:02:35,119
而在海底電纜

83
00:02:35,119 --> 00:02:36,839
一旦電纜被切斷

84
00:02:36,839 --> 00:02:38,220
整個島的網路

85
00:02:38,220 --> 00:02:38,959
金融

86
00:02:38,959 --> 00:02:39,619
通信

87
00:02:39,619 --> 00:02:40,839
都會陷入癱瘓

88
00:02:40,839 --> 00:02:43,359
那如何保證在最極端的環境下

89
00:02:43,359 --> 00:02:45,899
在島內也能及時保持通訊呢

90
00:02:45,899 --> 00:02:48,320
低軌道通信衛星就能發揮作用

91
00:02:48,320 --> 00:02:51,140
其實類似事件以前就發生過

92
00:02:51,140 --> 00:02:52,200
2006年

93
00:02:52,200 --> 00:02:54,739
恆春地震引發海底泥石流

94
00:02:54,959 --> 00:02:56,339
旅送海峽的幾條

95
00:02:56,700 --> 00:02:57,760
電纜被衝斷

96
00:02:57,760 --> 00:03:00,140
結果東亞和歐美的通信

97
00:03:00,140 --> 00:03:01,359
全都受到影響

98
00:03:01,359 --> 00:03:03,980
連銀行跨境結算都中斷了

99
00:03:03,980 --> 00:03:06,000
可見一旦電纜出問題了

100
00:03:06,000 --> 00:03:07,640
影響則是全球性的

101
00:03:07,640 --> 00:03:09,239
所以說低軌衛星

102
00:03:09,239 --> 00:03:11,299
不僅是上網的備用方案

103
00:03:11,299 --> 00:03:13,019
更是一種戰略保險

104
00:03:13,019 --> 00:03:15,339
除了本身的通訊作用

105
00:03:15,339 --> 00:03:16,839
像星鏈這樣的衛星

106
00:03:16,839 --> 00:03:18,120
還有一個重任

107
00:03:18,120 --> 00:03:20,839
就是爭奪有限的低軌道資源

108
00:03:20,839 --> 00:03:23,239
目前全世界航天國家

109
00:03:23,239 --> 00:03:25,120
都在搶佔這片新高地

110
00:03:25,120 --> 00:03:26,679
SpaceX的星鏈專案

111
00:03:26,680 --> 00:03:28,260
發展速度快得驚人

112
00:03:28,260 --> 00:03:31,040
從2020年正式提供服務

113
00:03:31,040 --> 00:03:33,220
到去年發射了2000顆衛星

114
00:03:33,220 --> 00:03:34,640
25萬用戶

115
00:03:34,640 --> 00:03:35,560
到今年8月

116
00:03:35,560 --> 00:03:38,200
衛星數量翻倍到4500顆

117
00:03:38,200 --> 00:03:39,700
使用者超過200萬

118
00:03:39,700 --> 00:03:41,920
而馬斯克的目標是發射

119
00:03:41,920 --> 00:03:43,620
4.2萬顆衛星

120
00:03:43,620 --> 00:03:45,440
這個數字意味著什麼

121
00:03:45,440 --> 00:03:47,540
意味著未來的地球上空

122
00:03:47,540 --> 00:03:49,340
會被它的衛星包網

123
00:03:49,340 --> 00:03:51,380
它可以讓任何一個國家斷網

124
00:03:51,380 --> 00:03:52,740
也能在戰爭中

125
00:03:52,740 --> 00:03:54,280
維持某一方的通訊

126
00:03:54,280 --> 00:03:55,920
這是徹底的網路霸權

127
00:03:55,920 --> 00:03:56,660
更重要的

128
00:03:56,660 --> 00:03:59,320
美國政府已經開始用星鏈

129
00:03:59,320 --> 00:04:00,220
做戰略佈局

130
00:04:00,220 --> 00:04:02,420
星鏈不只是互聯網公司

131
00:04:02,420 --> 00:04:05,000
它在技術上與美軍系統相容

132
00:04:05,000 --> 00:04:06,859
五角大樓正在測試

133
00:04:06,859 --> 00:04:08,620
如何通過星鏈衛星傳輸

134
00:04:08,620 --> 00:04:09,320
加密軍令

135
00:04:09,320 --> 00:04:10,100
換句話說

136
00:04:10,100 --> 00:04:12,700
星鏈成了美國的軍民合用系統

137
00:04:12,700 --> 00:04:13,960
中國當然不可能

138
00:04:13,960 --> 00:04:15,660
眼睜睜地看著別人

139
00:04:15,660 --> 00:04:16,980
壟斷太空通訊

140
00:04:16,980 --> 00:04:19,219
如果未來所有關鍵通信

141
00:04:19,219 --> 00:04:21,120
都繞不過美方的衛星網路

142
00:04:21,120 --> 00:04:22,320
那我們的軍用

143
00:04:22,320 --> 00:04:24,500
民用網路都將受制於人

144
00:04:24,500 --> 00:04:26,600
所以中國必須要有

145
00:04:26,660 --> 00:04:27,860
自己的星鏈

146
00:04:27,860 --> 00:04:28,660
這件事

147
00:04:28,660 --> 00:04:29,800
事關國家安全

148
00:04:29,800 --> 00:04:31,300
再看現實層面

149
00:04:31,300 --> 00:04:33,460
我們現在的千帆星座專案

150
00:04:33,460 --> 00:04:36,100
目標是發射上千顆衛星

151
00:04:36,100 --> 00:04:37,560
先覆蓋亞太

152
00:04:37,560 --> 00:04:38,760
再擴展到全球

153
00:04:38,760 --> 00:04:40,060
這個項目背後

154
00:04:40,060 --> 00:04:41,820
不只是科技公司

155
00:04:41,820 --> 00:04:43,700
還有航天科技集團

156
00:04:43,700 --> 00:04:46,400
航天科工等大型央企在參與

157
00:04:46,400 --> 00:04:47,560
問題在於

158
00:04:47,560 --> 00:04:50,020
要鋪設這樣一個龐大系統

159
00:04:50,020 --> 00:04:51,800
發射頻率必須高

160
00:04:51,800 --> 00:04:53,300
成本必須低

161
00:04:53,300 --> 00:04:55,160
這就需要可回收火箭

162
00:04:55,160 --> 00:04:56,020
這也是為什麼

163
00:04:56,020 --> 00:04:57,060
朱雀三號

164
00:04:57,060 --> 00:04:57,760
天龍

165
00:04:57,760 --> 00:04:58,620
長征八號

166
00:04:58,620 --> 00:04:59,419
改進型

167
00:04:59,419 --> 00:05:00,880
這些民用回收火箭

168
00:05:00,880 --> 00:05:02,280
都在加速的原因

169
00:05:02,280 --> 00:05:03,880
有了可回收火箭

170
00:05:03,880 --> 00:05:06,080
我們就能像space x那樣

171
00:05:06,080 --> 00:05:08,380
低成本批量發射衛星

172
00:05:08,380 --> 00:05:10,219
有了自己的低軌網路

173
00:05:10,219 --> 00:05:12,979
我們才能真正實現全球通信自主

174
00:05:12,979 --> 00:05:14,859
另外還有一個鮮為人知的

175
00:05:14,859 --> 00:05:17,719
現在中美在試圖爭奪金融話語權

176
00:05:17,719 --> 00:05:20,419
尤其是美國要維持金融霸權

177
00:05:20,419 --> 00:05:22,620
中國要推行人民幣國際化

178
00:05:22,620 --> 00:05:24,419
而像星鏈衛星技術

179
00:05:24,419 --> 00:05:25,859
也能參與到金融話語權

180
00:05:26,020 --> 00:05:27,060
的爭奪中

181
00:05:27,060 --> 00:05:29,020
比如2025年9月

182
00:05:29,020 --> 00:05:32,120
space x就有計劃開發晶片

183
00:05:32,120 --> 00:05:33,979
支援星鏈手機支付

184
00:05:33,979 --> 00:05:35,219
有評估認為

185
00:05:35,219 --> 00:05:38,280
得益於其全球衛星網路的優勢

186
00:05:38,280 --> 00:05:42,080
星鏈計劃有潛力結合加密貨幣技術

187
00:05:42,080 --> 00:05:45,780
推出全球加密支付或衛星結算系統

188
00:05:45,780 --> 00:05:49,080
如果星鏈未來綁定美元結算系統

189
00:05:49,080 --> 00:05:51,419
那全球交易的基礎設施

190
00:05:51,419 --> 00:05:53,359
就又落在美國手裡

191
00:05:53,359 --> 00:05:55,080
而中國自己的星網

192
00:05:55,080 --> 00:05:55,719
同樣

193
00:05:55,720 --> 00:05:58,280
完全可以以人民幣為結算基礎

194
00:05:58,280 --> 00:06:00,920
這就意味著中國能在太空層面

195
00:06:00,920 --> 00:06:03,420
建立一個去美元化的新通道

196
00:06:03,420 --> 00:06:05,620
所以當我們發問

197
00:06:05,620 --> 00:06:08,660
為什麼中國要急著搞自己的星鏈時

198
00:06:08,660 --> 00:06:10,520
其實背後的問題是

199
00:06:10,520 --> 00:06:12,480
未來的全球通信權

200
00:06:12,480 --> 00:06:13,820
金融結算權

201
00:06:13,820 --> 00:06:15,120
信息主導權

202
00:06:15,120 --> 00:06:16,520
究竟掌握在誰手裡

203
00:06:16,520 --> 00:06:18,260
從太空到地面

204
00:06:18,260 --> 00:06:19,960
從晶片到網路

205
00:06:19,960 --> 00:06:21,780
從火箭到衛星

206
00:06:21,780 --> 00:06:24,420
中國正在加速打通整個鏈條

207
00:06:24,420 --> 00:06:25,720
千帆星座的背後

208
00:06:25,720 --> 00:06:30,320
折射出的是一個國家在信息時代的安全自主權
