Schwerpunkte

  • Link Budgets & RF Performance: Margen, Availability, Worst-Case, Sensitivitäten
  • Interference & Spectrum: Co-channel/Adjacent, PFD/EIRP, operational constraints
  • Ground Segment: Teleports, Antennen, Feed/BUC/LNB, Waveguide, switching/redundancy
  • Measurements: G/T, EIRP, spectral regrowth, carrier metrics, pointing/polarization
  • IVA/Acceptance: Kriterien, Test Outline, Evidence Pack, Issue- & Punch-List

Engineering Output (abnahmefähig)

  • Traceable Link Budget Evidence Pack (Annahmen, Margen, Worst-Case)
  • Interference Assessment (Szenarien, Ursachen, Mitigation, Betriebsregeln)
  • Ground Segment Notes (Interfaces, Redundanz, Monitoring, Ops constraints)
  • Acceptance Evidence Pack (Criteria, Test results, deviations, closure)
  • Troubleshooting Log (hypotheses → tests → results → fix)

When to involve me

Typische „Symptome“, bei denen externer RF-/Acceptance-Support schnell wirkt:
  • Link Budget „ok“, Feldperformance nicht reproduzierbar
  • Interferenz / Degradation ohne klare Root Cause
  • Acceptance Gate: Kriterien/Evidence nicht sauber definiert
  • Teleport/Redundanz-Änderungen → unerwartete Nebenwirkungen
  • Terminal/Site Integration: pointing/pol, margins, repeatability issues
Link Budgets & Availability (DE) — engineering-grade

Ziel: Link Budgets, die in der Realität tragen. Fokus auf Traceability, Sensitivitäten, Worst-Case und operational constraints.

Inputs
Band, waveform/modcod, payload constraints, terminal class, antenna sizes, rain region, ops concept
Checks
clear-sky margins, fade margins, implementation losses, pointing/polarization loss, adjacent interference headroom
Outputs
Evidence Pack: assumptions, equations, parameter table, scenarios, sensitivity summary, conclusions

Beispiel-Gliederung Evidence Pack:

1) Assumptions & constraints 2) Parameter table (traceable) 3) Clear-sky performance 4) Availability (rain/fade) + margins 5) Worst-case scenarios (pointing/pol/impl losses) 6) Sensitivities (dominant drivers) 7) Conclusions + engineering recommendations
Interference & Spectrum (DE) — Analyse & Mitigation
  • Scenario-based assessment: co-channel/adjacent, intermod, cross-pol, out-of-band emissions
  • Metrics: C/N, C/I, Eb/N0, ACPR/ACLR, spectral regrowth, EVM (je nach System)
  • Operational constraints: PFD/EIRP limits, pointing windows, polarization plan, guardbands
  • Mitigation: filtering/linearization, power backoff, carrier plan, alignment, coordination

Ergebnis: dokumentierter Mitigation-Plan (technical + operational) inkl. Evidence.

Ground Stations / Teleports (DE) — Antenna/Feed, Redundanz, Ops
  • Antenna & feed chain: feed/OMT, waveguide, LNB/BUC/SSPA, LO stability, gain flatness
  • Pointing/polarization: alignment procedure, verification, drift, cross-pol isolation checks
  • Redundancy: 1+1 / N+1, switching logic, failover criteria, alarms, recovery
  • Monitoring: carrier metrics, spectrum monitoring, alarms, trend analysis, maintenance windows

Rahmenbedingungen: Engagement & Commercials.

IVA / Acceptance Support (DE)
  • Acceptance criteria: thresholds, availability targets, operational constraints
  • Test outline: scenario matrix, measurement method, pass/fail, tooling
  • Evidence pack: results, deviations, justification, closure actions
  • Handover readiness: ops notes, monitoring, maintenance, escalation paths

Next step

Engineering output (acceptance-ready)

  • Traceable Link Budget Evidence Pack (assumptions, margins, worst-case)

When to involve me

Typical “symptoms” where focused RF/acceptance support pays off quickly:
  • Link budget “fine”, field performance not reproducible
  • Interference/degradation without clear root cause
  • Acceptance gate: criteria/evidence not defined properly
  • Teleport/redundancy changes → unexpected side effects
  • Terminal/site integration: pointing/pol, margins, repeatability issues
