PRELIMINARY

OMES SSCO Robotic Servicing

Period of Performance: January 1, 2017 – December 31, 2017

Background

The Satellite Servicing Capabilities Office (SSCO) has a dual strategy to enable a future U.S. industry for the servicing of satellites:

1 Advance the state of robotic servicing technology to enable the routine servicing of satellites that were not designed with servicing in mind.

2 Position the U.S. to be the global leader in in-space repair, maintenance and satellite disposal.

This RTO will focus on the capabilities and skills required to perform on-orbit servicing for a well-known GSFC satellite case, Global Precipitation Mission (GPM).

For this RTO the spacecraft performing the on-orbit servicing shall be called Servicer 1. The Offeror shall demonstrate competencies for service scenarios including:

1. Proximity operations

2. Rendezvous and capture

3. Examine and inspect for probable causes for failures; and repair with

Servicer 1, sustain in mode for follow-on robot servicer or de-orbit decision (in communication with customer)

4. Refueling

5. De-orbit for demise with controlled re-entry

Task Description

Design and develop a mission, Servicer 1, which captures the Global Precipitation Measurement (GPM) spacecraft with an option to repair, refuel or de-orbit with a controlled re-entry to non-populated regions of Earth. The following URL contains relevant information for GPM.

http://www.nasa.gov/sites/default/files/files/GPM_Mission_Brochure.pdf https://directory.eoportal.org/web/eoportal/satellite-missions/g/gpm

Design the following mission components:

1. High level mission requirements

2. Concept-level design of a flight module that captures GPM satellite

(assume cooperative, i.e. target is under control and all instruments are http://www.nasa.gov/sites/default/files/files/GPM_Mission_Brochure.pdf https://directory.eoportal.org/web/eoportal/satellite-missions/g/gpm safed) The flight module is defined as the components of Servicer 1 used to perform on-orbit servicing and does not include the Servicer 1 bus or the satellite being serviced.

a. Include list of trade studies with recommended solutions for approaches and hardware to accomplish this task.

b. Identify single-point failures and rationale for redundancy or no redundancy

3. Mission Operations Concept

a. Include a mission timeline

b. Develop a proximity operations plan with focus on GN&C sub-system definition

c. Develop a rendezvous and capture operations plan with focus on robotic system definition. Also, describe any operational constraints on GPM

d. Develop a refueling plan

e. Develop a plan to examine and inspect GPM for probable causes of failures. Develop a plan to repair with Servicer 1, sustain in mode for follow-on robot servicer or de-orbit decision

f. Develop ground operations concept for telemetry, tracking and control

4. Identify key enabling technologies for this mission and its development plan to i) Complete the task and/or ii) Make the existing approaches more efficient and/or iii) Minimize significant risks to GPM
