Modification Application of Orbcomm License Corp.
IBFS File No. SAT-MOD-20110801-00141
Call Sign: S2103
Dear Mr. Sonnenfeldt and Mr. Goodman:
On August 1, 2011, Orbcomm License Corp. filed the referenced application to modify
the license for Orbcomm's non-voice, non-geostationary, low-Earth orbit (Little LEO) satellites.
Pursuant to Section 25.112 of the Commission's rules,1 we are dismissing the application as
incomplete. Furthermore, we ask that in any re-filed application, Orbcomm address a number of
questions which, while not grounds for dismissal, will facilitate Commission processing of the
Section 25.114(d)(14)(ii) requires an applicant to indicate that the "space station operator
has assessed and limited the probability of accidental explosions during and after completion of
mission operations." Orbcomm's application indicated that Orbcomm "believes there is virtually
no possibility" that its spacecraft will explode on-orbit,2 but did not indicate whether that belief
was based on a formal assessment. In any re-filed application, please indicate whether Orbcomm

for filing, any space station application that is not substantially complete, contains internal inconsistencies, or does
not substantially comply with the Commission's rules.

has completed a failure mode verification analysis concerning accidental explosions, and provide
a copy of that analysis.3
Section 25.114(d)(14)(iv) requires an applicant to disclose the "quantity of fuel--if any--
that will be reserved for post-mission disposal maneuvers." The Commission has indicated that
disclosure statements must indicate the "amount of fuel, in kilograms, that is intended to be
reserved to accomplish post-mission disposal, as well as the methodology used to derive the
quantity, including the methods used to determine and address fuel gauging uncertainty."4
Orbcomm's application did not specify the quantity of fuel reserved, instead indicating that
"sufficient" fuel would be reserved,5 and did not address fuel gauging uncertainty.
Although not a basis for dismissal, we request that any re-filed application provide the
following information:
Concerning collision avoidance between the Orbcomm spacecraft and the
International Space Station, please provide an organizational point of contact within NASA with
respect to the operator-to-operator coordination described at Exhibit B, Page B-4 of the
application narrative.
Concerning collision avoidance between the second stage of the Space X launch
vehicle and the International Space Station, please indicate whether Orbcomm or its launch
provider are undertaking operator-to-operator coordination with NASA, and in particular with
respect to operations of the second stage following separation of the Dragon capsule.
Please provide additional information and explanation of the statement, on the
twenty-second page of the application narrative, that "there will be no formal and active collision
avoidance monitoring systems in place for the OG2 satellites." In particular, please indicate
whether Orbcomm considers its coordination with NASA and the Joint Space Operations Center
described at Exhibit B, Page B-5, as an informal coordination, and provide any other information
concerning the nature, extent, and duration of the coordination with NASA and JSPOC.
Please indicate whether, given the "enhanced satellite maneuvering capabilities"6
of the Orbcomm OG2 satellites, Orbcomm intends, during orbit raising and at its operational
orbit, to undertake collision avoidance maneuvers in the event a high risk of collision is
identified and confirmed. Please indicate whether any fuel has been budgeted for such
Concerning atmospheric re-entry of the OG2 satellites, Orbcomm estimates a risk
of casualty per satellite of 3.9 in 10,000. This exceeds the acceptable risk of 1 in 10,000
specified in the U.S. Government Orbital Debris Mitigation Standard Practices. The application
also indicates that Orbcomm's analysis is based on "conservative assumptions" that "several of

the more dense components" of the spacecraft will reach the surface of the Earth, but that "it is
very likely none of the disposed satellite mass will survive re-entry."7 The application did not
provide any factual information or analysis in support of this assertion. Please provide any such
supporting factual information and analysis, and, if appropriate, revise Orbcomm's overall risk
assessment accordingly. Orbcomm may also wish to discuss possible insurance arrangements in
connection with atmospheric reentry of the OG2 satellites.8
Concerning the second stage of the SpaceX launch vehicle, please describe the
post-mission disposal plan for this space object, including whether it will be disposed of through
controlled atmospheric re-entry. In the event disposal will be through controlled re-entry, please
provide the projected geographic region of the debris field of the surviving components and
fragments, if any, and any measures taken to forewarn people who are likely to be in the
geographic region during the time period of the re-entry. In the event disposal will be through
uncontrolled re-entry, please provide a projection of orbital lifetime and, for re-entry:
a. An estimate of the number of components and fragments, and their estimated
dimensions and mass, likely to survive to the Earth's surface.
b. An estimate of the probability of human casualty resulting from surviving
components and fragments of the satellite.
c. A full description of the assumptions and parameters used in developing the
Accordingly, pursuant to Section 25.112(a) of the Commission's rules,9 and Section
0.261 of the Commission's rules on delegations of authority,10 we dismiss the modification
application of Orbcomm License Corp., without prejudice to re-filing.11
