Accuracy analysis in support of the global quality assessment of MISR georectified radiance product
Instantaneously, the nine pushbroom cameras of the Multi-angle Image SpectroRadiometer (MISR) instrument view the Earth at nine discrete angles, ranging from forward 70 deg, 60 deg, 45 deg, 25 deg, nadir, to symmetric aftward angles in the along-track direction.

The JPL Hg(sup +) Extended Linear Ion Trap Frequency Standard: Status, Stability, and Accuracy Prospects
Microwave frequency standards based on room temperature (sup 199)Hg(sup +) ions in a Linear Ion Trap (LITS) presently achieve a Signal to Noise and line Q inferred short frequency stability. Long term stability has been measured for averaging intervals up to 5 months with apparent sensitivity to variations in ion number/temperature limiting the flicker floor.

Accuracy of the Residual Delay Absolute Phase Algorithm
Interferometric synthetic aperture radar (IFSAR) has become a useful technology for producing high-quality topographic maps. These measurements are required to reconstruct the three-dimensional coordinate of a point in an IFSAR image: the range, azimuth and elevation. The first is obtained by timing the return of the radar pulse, the second by measuring the doppler shift, and the last by measuring the phase difference between the signals received at two displaced antennae.
