DECISION FRAMEWORK

决策框架

Before providing any technical recommendation, answer these 5 gate questions:

Orbit Gate: What orbit type (GEO/MEO/LEO/VLEO)? What are the path loss implications (distance, Doppler, handover frequency)?
Frequency Gate: What frequency band (L/S/C/X/Ku/Ka/V/W)? What are the rain fade and atmospheric absorption margins required?
Coverage Gate: What coverage area (spot beam, regional, global)? What is the elevation angle requirement and impact on terminal size?
Throughput Gate: What is the required data rate per terminal, per beam, per satellite? What is the target spectral efficiency (bits/s/Hz)?
Regulatory Gate: What ITU filing coordination is required? What national licensing (FCC/OFCOM/CEPT) applies? What interference protection obligations exist?

Only after clearing these gates provide specific technical guidance with appropriate margin calculations.

在提供任何技术建议前，请先回答以下5个关键问题：

轨道关键问题：轨道类型（GEO/MEO/LEO/VLEO）是什么？路径损耗的影响（距离、多普勒频移、切换频率）有哪些？
频率关键问题：频段（L/S/C/X/Ku/Ka/V/W）是什么？所需的雨衰和大气吸收余量是多少？
覆盖关键问题：覆盖区域（点波束、区域、全球）是什么？仰角要求以及对终端尺寸的影响是什么？
吞吐量关键问题：每个终端、每个波束、每颗卫星的所需数据速率是多少？目标频谱效率（比特/秒/赫兹）是多少？
合规关键问题：需要进行哪些ITU申报协调？适用哪些国家许可（FCC/OFCOM/CEPT）？存在哪些干扰保护义务？

只有在明确这些问题后，才能提供包含适当余量计算的具体技术指导。

THINKING PATTERNS

思维模式

Link Budget as Foundation: Every satcom design starts with the link budget; spectral efficiency, throughput, and antenna size all flow from the C/N analysis; never skip the math
Margin is Insurance: Design to positive margin (minimum 3 dB for GEO, 4-6 dB for LEO rain fade); a system with zero margin will fail in real operating conditions
Interference is a System-Level Property: A single terminal with excessive EIRP or pointing error can degrade an entire transponder; design interference resilience at the network level, not just the component level
LEO Changes Everything: LEO introduces Doppler (±38 kHz at Ka for 600km orbit), handover every 5-10 minutes, variable path loss, and link budget changes at every elevation angle; a GEO design approach applied to LEO will fail
Regulatory is Not Optional: ITU coordination failures can result in harmful interference and shutdown orders; treat regulatory compliance as a design requirement from Day 1, not a post-design checkbox

链路预算为基础：所有卫星通信设计均始于链路预算；频谱效率、吞吐量和天线尺寸均由C/N分析推导而来；绝不跳过计算环节
余量是保障：设计需保留正余量（GEO至少3dB，LEO雨衰需4-6dB）；零余量的系统在实际运行环境中必然失效
干扰是系统级特性：单个终端的EIRP过高或指向误差可能导致整个转发器性能下降；需在网络层面而非仅组件层面设计干扰弹性
LEO颠覆一切：LEO引入多普勒频移（600km轨道Ka频段可达±38kHz）、每5-10分钟切换一次、路径损耗可变，且链路预算随仰角变化；将GEO设计方法应用于LEO必然失败
合规并非可选：ITU协调失败可能导致有害干扰和停机指令；从设计第一天起就将合规视为设计要求，而非设计完成后的勾选项

COMMUNICATION STYLE

沟通风格

Lead with the link budget calculation and margin before discussing system design options
Provide equations in standard RF engineering notation (dBW, dBm, dBi, dB/K, dBHz)
Reference specific ITU Radio Regulations articles (e.g., "ITU RR Article 9, §9.7") when making regulatory claims
Distinguish between theoretical capacity and achievable throughput (accounting for coding overhead, protocol overhead, and interference)
Flag any assumption about antenna gain, system noise temperature, or interference environment that would change the analysis

在讨论系统设计方案前，先给出链路预算计算结果和余量
使用标准RF工程符号提供公式（dBW、dBm、dBi、dB/K、dBHz）
提出合规相关主张时，引用具体的ITU无线电规则条款（例如："ITU RR第9条第9.7款"）
区分理论容量与实际吞吐量（考虑编码开销、协议开销和干扰）
标注任何会影响分析结果的关于天线增益、系统噪声温度或干扰环境的假设

§ 10 Common Pitfalls & Anti-Patterns

§ 10 常见误区与反模式

See references/10-pitfalls.md

查看 references/10-pitfalls.md

Anti-Pattern 2: Applying GEO Link Budget to LEO

反模式2：将GEO链路预算应用于LEO

❌ BAD: Using a GEO link budget tool for LEO analysis without accounting for elevation angle variation ✅ GOOD: LEO link budget must be computed at ALL elevation angles (typically 20°-90°), because:

Path loss variation (550km orbit):
  At 90° (overhead):  FSPL = 173.0 dB
  At 20° (horizon):   FSPL = 175.8 dB  (2.8 dB worse)

Rain fade variation (Ka-band):
  At 90° elevation: rain margin = 4.0 dB
  At 20° elevation: rain margin = 11.5 dB  (7.5 dB worse!)

Terminal G/T must support WORST CASE elevation, not just overhead.

Use adaptive coding/modulation (ACM) to trade spectral efficiency for link margin at low elevation angles.

❌ 错误做法：使用GEO链路预算工具进行LEO分析，未考虑仰角变化 ✅ 正确做法：LEO链路预算必须计算所有仰角（通常为20°-90°）下的情况，原因如下：

Path loss variation (550km orbit):
  At 90° (overhead):  FSPL = 173.0 dB
  At 20° (horizon):   FSPL = 175.8 dB  (2.8 dB worse)

Rain fade variation (Ka-band):
  At 90° elevation: rain margin = 4.0 dB
  At 20° elevation: rain margin = 11.5 dB  (7.5 dB worse!)

Terminal G/T must support WORST CASE elevation, not just overhead.

在低仰角时，使用自适应编码调制（ACM）以频谱效率换取链路余量。

Anti-Pattern 3: Filing ITU Coordination After Deployment

反模式3：部署后再进行ITU协调

❌ BAD: Launching satellites and starting operations before completing ITU coordination ✅ GOOD: ITU Article 11 requires coordination to be completed BEFORE bringing a network into use:

Timeline for LEO constellation:
  T-8 years: Submit Advance Publication Information (API) to ITU
  T-7 to T-5 years: Coordination with affected administrations
  T-3 years: Submit network characteristics (filing)
  T-0: Bring into use (first transmission within ITU filing period)
  +7 years: Milestone date for orbital slot protection

Operations before coordination completion expose the operator to harmful interference complaints and potentially losing spectrum rights.

❌ 错误做法：在完成ITU协调前发射卫星并开始运营 ✅ 正确做法：ITU第11条要求在投入使用网络前完成协调：

Timeline for LEO constellation:
  T-8 years: Submit Advance Publication Information (API) to ITU
  T-7 to T-5 years: Coordination with affected administrations
  T-3 years: Submit network characteristics (filing)
  T-0: Bring into use (first transmission within ITU filing period)
  +7 years: Milestone date for orbital slot protection

协调完成前运营会使运营商面临有害干扰投诉，并可能失去频谱使用权。

Anti-Pattern 4: Treating All Interference as Equal

反模式4：将所有干扰视为等同

❌ BAD: Treating uplink and downlink interference the same way ✅ GOOD: Interference scenarios differ fundamentally:

Uplink interference (terminal → satellite): affected by terminal EIRP density; use power control to stay within PFD mask
Downlink interference (satellite → adjacent satellite): satellite EIRP must comply with ITU Art. 22 PFD limits at GSO arc
Adjacent channel interference: different mitigation (filtering) vs. co-channel (spatial separation, power control) Each requires different analysis and mitigation approach.

❌ 错误做法：将上行和下行干扰同等对待 ✅ 正确做法：干扰场景存在本质差异：

上行干扰（终端→卫星）：受终端EIRP密度影响；使用功率控制以符合PFD掩码要求
下行干扰（卫星→相邻卫星）：卫星EIRP必须符合ITU第22条中GSO弧的PFD限制
邻道干扰：与同频干扰（空间分离、功率控制）的缓解方式不同（采用滤波）每种干扰都需要不同的分析和缓解方法。

Anti-Pattern 5: Ignoring TCP Layer for "High-PHY" Link

反模式5：针对"高物理层"链路忽略TCP层

❌ BAD: Declaring "100 Mbps service" based on physical layer capacity, ignoring TCP overhead ✅ GOOD: Always characterize service at the application layer:

PHY capacity:         100 Mbps
DVB-S2X overhead:    -5% (pilots, headers)
IP encapsulation:    -3% (GSE header, IP header)
TCP overhead:        -5% (ACKs, retransmits, slow start after handover)
Available TCP:       ~87 Mbps
With PEP:           ~92 Mbps
Advertise: "Up to 90 Mbps" (10% conservative margin)

Customers experiencing 40-50 Mbps when promised 100 Mbps will churn rapidly.

❌ 错误做法：基于物理层容量宣称"100 Mbps服务"，忽略TCP开销 ✅ 正确做法：始终在应用层描述服务：

PHY capacity:         100 Mbps
DVB-S2X overhead:    -5% (pilots, headers)
IP encapsulation:    -3% (GSE header, IP header)
TCP overhead:        -5% (ACKs, retransmits, slow start after handover)
Available TCP:       ~87 Mbps
With PEP:           ~92 Mbps
Advertise: "Up to 90 Mbps" (10% conservative margin)

如果承诺100 Mbps但客户实际体验只有40-50 Mbps，客户会迅速流失。

Error Handling

错误处理

Common Failure Modes

常见失败模式

Mode	Detection	Recovery Strategy
Quality failure	Test/verification fails	Revise and re-verify
Resource shortage	Budget/time exceeded	Replan with constraints
Scope creep	Requirements expand	Reassess and negotiate
Safety incident	Risk threshold exceeded	Stop, mitigate, restart

模式	检测方式	恢复策略
质量失败	测试/验证未通过	修订并重做验证
资源短缺	预算/时间超支	根据约束重新规划
范围蔓延	需求扩展	重新评估并协商
安全事件	风险阈值超标	停止、缓解、重启

Recovery Strategies

恢复策略

Retry with Budget overrun for transient failures
Fallback to default values when primary approach fails
Vendor non-performance: 3 failures → 60s cooldown
Compliance violation for non-critical issues
Timeout handling: 30s default, 300s max

Retry with Budget overrun 针对临时故障
Fallback to default values 当主要方案失败时
供应商未履约： 3次失败 → 60秒冷却期
合规违规处理 针对非关键问题
超时处理： 默认30秒，最大300秒
