NGSO Popularity Raises Questions About Place for GSO, FCBA Panelists Say

As the number of nongeostationary orbit satellites (NGSOs) in orbit or planned for launch rises, the role of geostationary orbit satellites (GSOs) is coming into question. "Over time, we'll see a shift" to NGSOs, Whitney Lohmeyer, OneWeb communications systems and regulatory engineer, said Friday as the FCBA's International Telecommunications Committee held a brown bag lunch panel talk about NGSO regulatory issues. Most services that a GSO satellite can provide, an NGSO can do as well but with lower latency, Lohmeyer said. However, said panelist Audrey Allison, Boeing director-frequency management, "we're not getting out of [the GSO] business. [NGSO] is an important supplement." But, she said, that GSO companies like EchoStar are investing in NGSOs "is pretty telling." GSO fits some niches, like video distribution, better than NGSO, said panelist Suzanne Malloy, O3b vice president-regulatory affairs. "The introduction of a new technology doesn't mean everything old is retired," Malloy said. A Boeing NGSO system is in the design stage now with the idea that holders of existing fixed satellite service spectrum allocations could be getting more use out of that spectrum through NGSOs, Allison said. OneWeb expects the first launches of its 648-satellite constellation to start in 2017 and has applications worldwide with numerous nations for the 50-150 gateways it needs, Lohmeyer said. It also is working on developing a terminal that operates both with GSOs and NGSOs, she said: "It'd be ideal, but it's challenging." And O3b has 12 NGSO satellites in orbit serving more than 40 customers in 20-plus countries, and is planning for eight more satellites, Malloy said. When asked about regulatory reforms the panelists would like to see, Malloy said the FCC's Part 25 rules tend to be both GSO-oriented and "very specific" on technical issues like antenna performance, which complicates changing the rules as NGSO regulations would have to be just as granular. Allison said Boeing's "particular pet peeve" is wanting to see better rules regarding milestone compliance -- an issue the Satellite Industry Association also brought up in an ex parte filing posted Tuesday in docket 12-267 (see 1509230022). SIA called on the FCC to simplify the critical design review (CDR) milestone, saying the routine submission requirement of CDR information both prolongs review and raises the danger of inadvertent disclosure of sensitive competitive information.
