    dct:description "<p>We propose to perform a study and experimental demonstration of Optical Clock Technology for enhanced Coherent Optimetrics, and ultra-high precision time and frequency transfer. In coherent optimetrics configuration, the system will be locked to an Optical Clock to demonstrate <strong>nm</strong> range and ranging rate performance. In time and frequency transfer mode, an optical frequency comb will be lock the Optical Clock to demonstrate an unprecedented precision time and frequency transfer&nbsp;to remote satellite (such as TDRS). It makes precision time and clock available on any satellite without having to&nbsp;carry bulky optical clock source on board. This dual technology, <strong>coherent optimetrics</strong> and <strong>precision optical clock time frequency transfer</strong> will greatly advance the state of art on ranging, clock and timing in space. Greatly benefit both Gravitational [3] and Planetary [4] sciences. This technology development is leveraging the vast technology progress in the fields: <strong>a.</strong> High speed coherent optical communication (Telecomm) (&gt;100GBPS) with photonic integrated circuit (PIC) and high speed analog and digital electronics . &nbsp;<strong>b. </strong>Low noise laser source &nbsp;and optical clock development&nbsp;from both gravity wave measurement (LISA) and optical clock research. <strong>c. </strong>optical frequency comb development for high precision metrology, spectroscopy, etc . This proposal also leverages last couple of years&rsquo; project &ldquo;High Precision RF Ranging and Range Rate Measurements over Optical Carrier and Laser Communication in Cubesat Platform&rdquo;, and &ldquo;Coherent Optimetric Measurements and Optical Communication&rdquo;. The success of this study will provide platform with both ranging over continuous optical phase (~nm error) and high precision optical frequency transfer (relative frequency error of 10<sup>-17</sup>). It will be game changing technology with such high precision ranging and high bandwidth communication. It will service both science and NAV/COMM at a new level of ranging precision and comm capacity. It will also advance the state-of-the-art for the optical comm system with high bandwidth and high precision ranging. It will be an enabler for precision formation flying missions that include: virtual sensors, sensor webs, large-number-multi-spacecraft distributed mission, autonomous rendezvous &amp; docking; and enabler for gravitational based small-sat scientific missions.</p>" ;
