## Abstract

Currently, Globalstar, Inc. (Globalstar) operates a Mobile- Satellite Service (MSS) system in the 1610-1626.5 MHz band (Big LEO L- band) and the 2483.5-2500 MHz band (Big LEO S-band). Globalstar, a code division multiple access (CDMA) system, is authorized to operate an ancillary terrestrial component (ATC) in the 1610-1615.5 MHz and 2487.5-2493 MHz segments of the Big LEO bands. By this decision, the Federal Communications Commission (Commission) increases the spectrum in which Big LEO MSS systems using CDMA technology operate ATC. As a result, the Commission increases the spectrum in which Globalstar may operate ATC in the Big LEO L-band to include the 1610-1617.775 MHz band, an increase of 2.275 megahertz, and in the Big LEO S-band to include the 2483.5-2495 MHz band, an increase of six megahertz.
