Claim:
1. An inertial measurement apparatus based on atom interferometry and comprising: a vacuum chamber; a plurality of atom interferometers including at least a first atom interferometer and a second atom interferometer, the first atom interferometer being configured to generate a first measurement corresponding to a common inertial input based on a first atom sample, and the second atom interferometer being configured to generate a second measurement corresponding to the common inertial input; and a plurality of atom capture sites housed within the vacuum chamber, the plurality of atom capture sites including at least a first atom capture site and a second atom capture site, the first atom capture site being configured to capture the first atom sample and to provide the first atom sample to the first atom interferometer, and the second atom capture site being configured to recapture the first atom sample from the first atom interferometer, following the first measurement, and to provide the first atom sample to the second atom interferometer, the second atom capture site being further configured to capture a second atom sample different from the first atom sample and to provide the second atom sample to a respective atom interferometer of the plurality of atom interferometers.
