If you process your data in less than 24 hours after collection, OPUS will use Ultra-Rapid orbits. While most CORS are archived within 30-minutes past the hour, some aren't available until the next day. Wait a day before submitting your file: OPUS will use the best CORS and orbits available at the time you upload your data.Observe on a different day, at a different time of day.To maximize independence between observations: Observe again: A second independent observation which yields a similar solution is an easy way to increase confidence in your results.'Evaluation of the Online Positioning User Service for Processing Static GPS Surveys: OPUS-Projects, OPUS-S, OPUS-Net, and OPUS-RS,' ASCE Journal of Surveying Engineering, 145(3): 05019002. See Gillins, D.T., Kerr, D., and Weaver, B. Please note: this figure is a result of a published regional study,ДЄnd the performance of OPUS may be slightly better or worse in your geographic location. The figure below shows the correlation between session duration and accuracy. Observe longer: A longer session provides OPUS a better opportunity to accurately fix ambiguities and mitigate multipath error.Improving your OPUS results: Follow these guidelines to improve the quality of your OPUS solution: Our experiments indicate that the actual error is less than these estimated accuracies more than 95 percent of the time. Rapid-Static: The best estimates of coordinate errors are the standard deviations reported by single baseline analysis.One advantage of peak-to-peak errors is that they include any error from the CORS (base station) coordinates. Static: For each coordinate (X, Y, Z, О¦, О», h, and H), static processing provides the range of the three individual single baselines,Д¬alled peak-to-peak errors.Local multipath or adverse atmospheric conditions may also negatively impact your solution. User errors (such as misidentification of antenna or ARP height) cannot be detected. However, estimating the accuracy for a specific solution is difficultД«ecause formal error propagation is notoriously optimistic for GPS reductions. Under normal conditions, most positions can be computed to within a few centimeters. Rapid-static processing has stricter requirements for data continuity and geometry in some remote areas of the country OPUS-RS may not work. Rapid-Static: Files that are 15 minutes to 2 hours in duration are processed using RSGPS rapid-static software.Your coordinates are the average of three independent, single-baseline solutions, each computed by double-differenced carrier-phase measurements from one of three nearby CORSs. Static: Files that are 2 to 48 hours in duration are processed using PAGES static software.Caution! If you choose to set a profile, your selections will override the optimized defaults for all subsequent uploads.Дepending on the duration of your data file, OPUS will use either static or rapid-static processing:.Subsequent uploads will require only your email and a data file to apply your customized defaults.If you choose to set a profile, OPUS will save your email, antenna type and height, and options used.Choose your State Plane Coordinate System ( SPCS) zone.Select additional options By clicking the 'Options' button, you can: Your OPUS solution will be sent to this address when processing is complete.ДҐ. See antenna calibration for a drawing of the ARP for your antenna (usually the center of the base or tripod mount). Enter your ARP heightД®nter the vertical height (in meters) of your Antenna Reference Point ( ARP) above the mark. Choosing an incorrect antenna may result in a height error as large as 80 cm and a horizontal error up to 1 cm. Correctly selecting your antenna will help OPUS apply the appropriate antenna calibration model to counter the unique measurement biases inherent in each antenna's design. To find the correct antenna type, browse antenna calibrations. OPUS accepts all mask angles, but only satellites more than 10В° above the horizon are used.OPUS decimates all recording rates to 30 seconds.OPUS only uses GPS observables (even if the file contains other GNSS observables).For compressed files: all files must share the same antenna type and height Compressed UNIX, gzip, pkzip, and Hatanaka formats.Record data at intervals of 1, 2, 3, 5, 10, 15, or 30 seconds.Files under 2 hours must include both P2 observables and either P1 or C1 observables.Include a minimum of 15 minutes and maximum of 48 hours of data, not crossing UTC midnight more than once.Include static data only (the antenna must remain unmoved throughout the observing session).
