Exhibit D Description of Application Ligado hereby requests an extension of the license term of MSAT-2 for one year, through December 31, 2018. Ligado has launched and commenced operations of SkyTerra 1, the replacement satellite for MSAT-2, and most customers have been transitioned to SkyTerra 1. 1 However, some customers continue to receive service on MSAT-2 and have asked that Ligado continue to provide service on MSAT-2. MSAT-2 remains operational and, in addition, is a suitable back-up satellite for SkyTerra 1 customers, 2 some of which provide service to government and public safety entities. Further, Ligado has confirmed that, at the conclusion of the requested extension period, MSAT-2 will have sufficient fuel to de-orbit to a disposal altitude that complies with the Inter-Agency Space Debris Coordination Committee standard, as stated in the MSAT-2 orbital debris mitigation plan. 3 The proposed extension therefore would not impact the orbital debris mitigation plan for the satellite. The Commission previously has granted similar requests to extend the license term of MSAT-2, 4 and granting the instant request similarly would serve the public interest. 1 See Report No. SAT-00759 (Feb. 18, 2011). 2 See Annual Satellite Status Report, Call Signs AMSC-1 and S2358 (June 29, 2012) (documenting the transition of SkyTerra 1 customers to MSAT-2 when unusually intense solar activity temporarily impacted operations of SkyTerra 1). 3 See IBFS File No. SES-MFS-20070530-00731, Technical Narrative at 35-36. 4 See Stamp Grant, IBFS File No. SAT-MOD-20151218-00083 (granted Feb. 11, 2016); Stamp Grant, IBFS File No. SAT-MOD-20141212-00128 (granted May 14, 2015); Stamp Grant, IBFS File No. SAT-MOD-20131204-00143 (granted Feb. 11, 2014); Stamp Grant, IBFS File No. SAT-MOD-20121128-00203 (granted Jan. 24, 2013).
