Design and develop a star tracker (using interferometery fringe methodology
developed by NASA's Jet Propulsion Laboratory (JPL)) that is extremely
accurate, light weight and consumes little power as compared to current
commercial products. The developed star tracker will be designed for potential
deployment on the Trident II (D5) weapons system and for astronomical data
collections (including measures of stellar photometry, variability, and astrometry)
that are used by the Navy.
Current commercial star trackers’ size, weight, and power (SWaP) needs preclude
the Navy from considering deploying these star trackers to the Trident II
weapon system. Acquisition of an accurate, low-weight, small, and
power-efficient star tracker would allow strategic weapon systems to be
deployed with less expensive maintenance cost while also providing weapons
system designers options to increase weapon system performance with less
expensive hardware cost and maintenance. Furthermore, the new developed star
tracker could assist in exo-atmosheric astronomical data collections needed for
Navy, DoD and other commercial utility. The innovation needs to leverage
already developed techniques by NASA JPL into a hardware electronics
instruments package that is portable for missile and spacecraft environments.
The Navy expects the star tracker to be no bigger than 64 cubic inches, weigh
no more than 500 grams, and powered for at least two hours, and that new technology
will demonstrate calibration of star tracker focal planes up to 100 times more
accurate than current commercial capability. The star tracker will be expected
to interface with navigation systems that will be matured through the proposal
cycle. Power range for the star tracker should be 5W, or under, of navigation
Develop and define a concept design for a star tracker that employs a NASA JPL
interferometric fringes technique to measure stars extremely accurately. Ensure
that the star tracker will be very small in size and will require low amounts
of power. Work with the Navy to fully understand and document the star tracker
SWaP and accuracy requirements since the star tracker is to be no bigger than
64 cubic inches, weigh no more than 500 grams, and powered for at least two
hours, and that the accuracy of the star tracker to be up to 100 times more
accuracy than current technology with pointing accuracy of 0.04 arc seconds.
Identify risks in the proposed concept. Develop Phase II plans that include
ways to mitigate those risks.
Produce and deliver a prototype star tracker. Assist the Navy in setting up the
prototype star tracker for Hardware-in-the-Loop (HWIL) testing that emulates
missile and space craft environments; and includes trouble shooting plus
resolving implementation and execution issues. Establish feedback loop with the
Navy for implementing changes due to prototype testing.
DUAL USE APPLICATIONS: Deliver to NSWCDD/USNO a refined star tracker manufacturing
prototype that the Navy can test for its function and portability in their
land-based HWIL testing facilities. Provide design and test cases that
demonstrate that the star tracker's accuracy is 100 times current technology
(based on JPL's techniques); and is small, lightweight, and portable according
the requirements matured in Phase I. Assist the Navy in setting up the star
tracker manufacturing prototype for HWIL testing that emulates missile and
space craft environments; and will include trouble shooting plus resolving
implementation and execution issues. Support field qualification testing with
Navy hardware and software applications. This product would support commercial
aerospace space navigation, telescope pointing and tracking.
