📋 Audit Checklist: itu-r SNG Field Operations

Field Security Audit // Node_Operational
Completion_Index0%

Terminal Technical Compliance

item_em-0

Modulation & Error Correction: Confirm the use of coherent QPSK modulation. Verify that Forward Error Correction (FEC) is active (e.g., Viterbi, Reed-Solomon).

item_em-1

EIRP & Peak Control: Verify that the e.i.r.p. (Equivalent Isotropically Radiated Power) is within the satellite operator's limits. Digital EIRP Limit: Confirm that digital SNG levels are lower than equivalent analogue carriers.

item_em-2

Off-Axis Emission: Audit the sidelobe suppression levels to ensure they meet the itu-r S.524 mask.

item_em-3

Cross-Polarization: Confirm that cross-polarization isolation is >30dB to prevent interference with adjacent satellite transponders.

Operational & Coordination Security

item_em-4

ATIS (Automatic Transmitter Identification System): Verify that the SNG.1070 ATIS signal is active and correctly identifies the operator.

item_em-5

Access Coordination: Confirm that a satellite "line-up" was performed with the satellite control center (SCC) before full-power transmission.

item_em-6

Auxiliary Circuits (Order-Wire): Verify that a secondary communication channel (GSM, Landline, or separate Sat circuit) is available for coordination.

Rapid Deployment Verification

item_em-7

Time-to-Air: Audit the setup time (Target <15 mins).

item_em-8

Environmental Resilience: Verify terminal weatherproofing and power stability (UPS/Generator).

item_em-9

Safety Verification: Confirm that the RF "Hazard Area" is cordoned off to prevent human exposure to the main beam.
