SPE-5 Lidar Error Analysis.
All analysis was performed using data provided to SNL in June, 2016.
Uncertainty, sensitivity, and error analysis and visualization of high-dimensional Input-output models
Our motivation was to explore high-dimensional input-output data space; create complex simulation models; respond to a lack of analysis tools; and create a systematic, step-by-step analysis process.

Mission SL-3 (AS 207/CM 117/IMU 31) G and N error analysis (Skylab 3)
Data are presented on G and N system performance and operation for the CM. Data of measured CM IMU test data are included.
Simulated trajectories error analysis program, version 2. Volume 2: Programmer's manual
A series of three computer programs for the mathematical analysis of navigation and guidance of lunar and interplanetary trajectories was developed. All three programs require the integration of n-body trajectories for both interplanetary and lunar missions. The virutal mass technique is used in all three programs. The user's manual contains the information necessary to operate the programs. The input and output quantities of the programs are described. Sample cases are given and discussed.
Mission SL-4 (AS 208/CM 118/IMU 34)G and N error analysis (Skylab 4)
Data on the gyro and navigation system performance and operation for the command module are presented. Each reported failure was analyzed with respect to its likelihood of occurence in flight and its impact on the mission.
A highly efficient error analysis program for the evaluation of spacecraft tests of general relativity with application to solar probes
A computer program is described which can be used to study the feasibility of conducting relativity experiments on a wide range of hypothetical space missions, and a few applications are presented for solar probes which approach the Sun within 0.25 to 0.35 AU. It is assumed that radio ranging data are available from these spacecraft, and that accuracies on the order of 15 meters can be achieved. This is compatible with current accuracies of ranging to Mariner spacecraft. At this level of accuracy, the range data are sensitive to a number of effects, and for this reason it has been necessary to include a total of up to 23 parameters in the feasibility studies, even though there are only two parameters of real interest in the relativity experiments.
