As rideshare launches become more commonplace, secondary payloads continue to be challenged by the limited choice of orbits, upper stage restart capability and risk-adverse nature of primary payloads to allow for flexibility in the deployment sequence. The result is that a secondary payload's final orbit is limited by its host and the propulsion capability of the individual spacecraft, particularly so for cubesat class passengers. Many of these challenges can be met through the use of a propulsive rideshare adapter or Orbital Maneuvering Vehicle (OMV). In addition, the use of an OMV to act as both a long-term host for payloads, as well as a traditional tug, has enabled novel mission concepts such as hub and spoke architectures for communications and data processing functionality for distributed sensing systems.

Moog has analyzed, developed and supported numerous missions employing OMV functionality. In this paper a number of case studies are described to illustrate the utility, value and flexibility of the OMV as a mission enabling technology. Cases examined include:

  • Accelerated deployment of a smallsat constellation, which results in the optimal satellite placement (revenue generation) in less than half the time of a traditional (passive) deployment.
  • A joint operational heliophysics and technology demonstration mission at the Earth-Sun L1 point piggybacking from a rideshare GTO launch opportunity.
  • A scenario to ferry multiple small payloads to Low Lunar Orbit (LLO) from earth orbit.
  • The performance of small satellite technology continues to improve at an exponential pace but, if small satellites continue to compromise optimal orbit for general space access, true potential cannot be fulfilled. In each of the scenarios identified, the particular use of an OMV gives rise to a number of shared launch opportunities that would not have previously been considered and improves the overall access to space for rideshare passengers.



    Christopher Pearson is a Senior Mission and Payload Engineer at Moog based in Golden, Colorado and has worked on a diverse set of military, commercial and scientific programs. Chris is currently leading development of the Moog family of Orbital Maneuvering vehicles but continues to assist customers mature mission concepts and conduct system design trades supporting projects. Chris holds a Bachelors degree in Mathematics as well as Masters degrees from Cranfield University, Imperial College London and Colorado University.

    Christopher Loghry is Space Systems Engineer supporting Moog's Space Sector with background in spacecraft propulsion. He joined Moog in 2012 as part of the AMPAC In-Space Propulsion (ISP) acquisition. He has supported the ISP business in addition to the larger Space business. He currently works for the Chief Technologist in an engineering role supporting propulsion, launch vehicle, and spacecraft missions particularly the Advanced Missions and Science (AMS) group. Prior to joining Moog, he worked for Lockheed Martin for seven years performing spacecraft propulsion system integration and test (I&T) operations including launch site propellant loading. This included many unique or first of their kind programs like AEHF, SBIRS, MUOS, JUNO, GRAIL, and several other commercial and military spacecraft. He received his Bachelor's of Science in Engineering (BsE) from Purdue University with a major focus in Aerospace Propulsion and a minor in Nuclear Engineering.

    Hallie Walden is the Director of Integrated Systems at Moog. She joined Moog in 2012 with the acquisition of Broad Reach Engineering. At Broad Reach Engineering she held the position of Director of Space Systems. Prior to Moog, Hallie was a Program Manager and an Advanced Systems Manager for Ball Aerospace Technologies Corp. - National Defense Systems in Broomfield, CO. In these roles she managed a number of programs that involved new product and new technology development for spacecraft and payload applications. She led the successful capture for a number of programs including small spacecraft and payload Prior to Ball, Hallie performed thermal and thermodynamic analyses at Lockheed Martin Space Systems in Littleton, CO and Allied Signal Aerospace in Torrance, CA for spacecraft, launch vehicles, fuel cell power systems, and heat exchangers. She taught thermodynamics courses for undergraduate Mechanical Engineering students at California State University, Long Beach. Hallie received a B.S. in Mechanical Engineering from Stanford University in 1986. She received her M.S. in Mechanical Engineering from Stanford University in 1988 with emphasis in thermodynamics and fluid mechanics.

    Joe Maly is a senior member of the Moog CSA technical staff and is Moog's ESPA Product Manager. He joined CSA in 1987 and since 1993 has led flight hardware and vibration suppression programs. Experienced in both analytical and experimental methods of structural dynamics, Joe has developed vibration suppression hardware for space structures, aircraft, medical equipment, and semiconductor manufacturing equipment. He was Principal Investigator for the development of ESPA, and he led the flight hardware program for the Hubble Space Telescope Solar Array Damper. Currently Joe is leading the Orbcomm Generation 2 (OG2) Satellite Dispenser team supporting the launch of multiple satellites with ESPA on Falcon 9 to populate the OG2 constellation.

    Len Zima is a Senior Space Systems Engineer supporting Moog's Space Access and Integrated Systems Business Unit with over 20 years experience in space system design, propulsion, fluids and mechanisms. He joined Moog in 2007 as part of Space Team Engineering supporting ARES / Constellation business capture and program execution. He was the lead project engineer for the concept, design and development of the J2X Main Engine Valve Actuators. Prior to joining Moog, he worked at Carleton Technologies, Inc. as the Engineering Product Manager for Shuttle Environmental Control and Life Support Systems (ECLSS) and Extravehicular Mobility Unit (EMU) Life Support SubSystem (LSS) for the Space Suit Assembly (SSA). Len started his career as a flight range safety analyst at VAFB, CA supporting Atlas, Delta, Minuteman and Bomarc missions before returning to school to pursue a MS degree in physics. He worked throughout the 1980's at Bell Aerospace-Textron on various programs including concept development for Peacekeeper Deep Based Weapons Systems (DBWS) and the Air Force Gravity Gradiometer Surveillance System (GGSS). He received his Bachelor's of Science in Aerospace Engineering (BsAE) from SUNY at Buffalo with a minor in advanced engineering mathematics.

    Marissa (Brummitt) Stender is a Systems Engineer for Moog Space and Defense. Within the Integrated Systems group she supports proposals, studies, and mission design, including the Orbital Maneuvering Vehicle. Before joining Moog, Marissa was the lead systems engineer for Surrey Satellite Technology US's Orbital Test Bed (OTB) mission. Ms. Stender received her bachelor of science and master of science degrees in Aerospace Engineering from California Polytechnic State University San Luis Obispo (2011). At Cal Poly, Marissa participated in the CubeSat Program and gained nanosatellite integration and test experience collaborating with the Naval Postgraduate School's (NPS) Space Systems Academic Group.

    Steve Witkowski is Sr. Market Manager for the Civil Segment of the Space Access and Integrated Systems Business Unit. He joined Moog in 1997 managing Intl Programs in the Space Products Division. Since this time he has worked in the Domestic and International Space Exploration and Launch Vehicle Markets leading efforts on such programs as Ariane 5, Vega, Altas V, Delta IV, Pegasus, Taurus, RL10, ISS, Mars Lander, SLS, Orion, Commercial Crew and Cargo, and ISS. Currently he is working business development and customer relations efforts associated with NASA and its efforts on the Journey to Mars, International Space Station, Space Exploration and Technology Development.
