What is Online Positioning User Service?

Online Positioning User Service (OPUS) allows users to submit their RINEX (Receiver Independent Exchange) format GPS data files online to the National Geodetic Survey (NGS), where the data will be processed to determine a position using NGS computers and software.

What is Opus in surveying?

OPUS is a popular NGS tool which helps survey-grade GPS users tie their local surveys to the National Spatial Reference System. By leveraging the processing software used to manage the Continuously Operating Reference Station (CORS) network, OPUS improves raw GPS results to within a few centimeters of accuracy.

What is NGS opus?

What is OPUS? NOAA’s Online Positioning User Service (OPUS) provides free access to high-accuracy National Spatial Reference System (NSRS) coordinates. OPUS uses software which computes coordinates using the NOAA CORS Network (NCN).

How long does opus take?

Although your unique treatment session will depend on your skincare goals and which areas, you’ll have treated, Opus Plasma treatments can take between 15 and 30 minutes. This may also be longer or shorter depending on if you opt for a topical anesthetic or treat multiple areas in the same treatment.

What is Rinex data?

In the field of geodesy, Receiver Independent Exchange Format (RINEX) is a data interchange format for raw satellite navigation system data. The RINEX format is designed to evolve over time, adapting to new types of measurements and new satellite navigation systems.

Which is are GNSS?

GNSS stands for Global Navigation Satellite System, and is the standard generic term for satellite navigation systems that provide autonomous geo-spatial positioning with global coverage. Common GNSS Systems are GPS, GLONASS, Galileo, Beidou and other regional systems.

How accurate is Opus?

OPUS-RS (rapid static) is designed to meet that requirement, producing coordinates with an accuracy of a few centimeters from user data sets spanning as short as 15 min.

What is Auspos?

AUSPOS is a free online GPS data processing facility provided by Geoscience Australia. AUSPOS works with data collected anywhere on Earth. You can submit dual-frequency geodetic quality GPS RINEX data observed in a ‘static’ mode to the GPS data processing system.

Does Opus plasma tighten skin?

Opus Fractionated Plasma can also improve skin textures to make your skin feel smoother and softer to the touch. If you struggle with sagging or drooping skin, Opus Fractionated Plasma works as a skin-tightening procedure to improve skin laxity and give it a more taut appearance.

How do I use Rinex files?

Specify where to save the raw data file: Click the browse button, navigate to a folder on your computer, then type a name for the raw data file. Click the save button. Turn on the raw data messages: Select “Raw Data (RINEX)” from the settings dropdown menu. Click the Apply button.

Which is better GPS or GNSS?

GNSS and GPS work together, but the main difference between GPS and GNSS is that GNSS-compatible equipment can use navigational satellites from other networks beyond the GPS system, and more satellites means increased receiver accuracy and reliability.
