  to promote ma rket entry, regulatory certainty, and spectrum efficiency. The Commission adopts 
rules clarifying protection obligations between non - geostationary satellite orbit, fixed -satellite

protections to a sunset period, and requires all NGSO FSS operators licensed or granted market 
access in the United States to coordinate with each other in good faith.  
DATES: Effective 20 July 2023, except for the amendment to Sec. 25.261 in  amendatory instruction

announcing the effective date of Sec. 25.261 in instruction 4.
