Inertial Navigation Systems (INS) a
re alternatives to GPS that operate using linear \;accelerometers and gyroscopes to calculate the user&rsquo\;s
position\, orientation\, and velocity using \;no external reference. Optical Sagnac gyroscopes are part of mod
ern day INS and are limited \;by thei
r ability to measure small rotations as they need a very large enclosed ar
ea. The Bragg \;Interferometer Gyrosc
ope in a Time Orbiting Potential Trap (BIGTOP) is a rotation detector 
\;using a Bose-Einstein Condensate (BEC)
to execute two Sagnac interferometers in a magnetic \;
span>trap. BIGTOP is an improvement upon a previous iteration
of a dual Sagnac interferometer \;whi
ch demonstrated rotation sensing. We have achieved atom interferometry wit
h BIGTOP and \;reached a Sagnac area
of 8 mm2 using multiple orbits\, an improvement by a factor of 16.&nbs
p\;Additionally\, we have taken our first
large dataset over the course of 24 hours\, which can be \;used to analyze the stability of our system. In tan
dem with BIGTOP\, we have also worked to \;characterize and operate a compact atom chip interferometer system b
uilt by Cold Quanta (CQ<
span style="font-size:11.0pt">system). We report
BIGTOP results\, progress with the CQ system\, and future work.
