EMI/RFI Upchannel Reporting Checklist Checklist Number

OPWS-07C (1 Apr 08)

This checklist outlines information personnel report to the GSSC upon encountering an Interfering Signal (IS) that affects the User Signal performance. Use this checklist to report EMI on any spectrum; each spectrum will fill out information as applicable.

For commercial upchannel reporting, fill out ALL lines; for UHF upchannel reporting, fill out only the lines with an asterisk (*).

Commercial SATCOM Owner-Operator will IMMEDIATELY and FIRST contact the GSSC to report the collected information.
