Previously called the CORS Time Series Tool, it computes and displays the daily residuals for up to 50 stations within the NCN as both individual time series and collectively on an interactive map. The mean, standard deviation, and root-mean-square (RMS) error of the residuals are also provided in a summary table that is available for download. This tool is optimized for plotting 30 to 90 days of data, but can be customized for other time frames. The earliest start date currently available is October 27, 2018, which is the completion date of the Mult-Year CORS Solution 2 (MYCS2<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Flnks.gd%2…>) and the first date coordinates from that solution are available. The end date can be as recent as 3 days before the present day. This 3 day time lag is so that the final orbits can be used in the network adjustment to create the daily solutions.

Station velocity estimates from GNSS time series are the backbone of defining stable global and regional reference frames that enable high precision positioning. Noise in the GNSS time series degrades the position observations and increases the uncertainty in the station velocity estimates. The source of the noise can be related to the instrument and processing strategies used, or can be from environmental sources such as the atmosphere and hydrological effects. This webinar will provide an overview of the types of noise present in GNSS time series and its effect on the velocity estimation. There will also be a discussion on the potential sources of noise, using GNSS time series in the Great Lakes region as an example of the effect of atmospheric and hydrological related noise. *Technical Content Rating: Intermediate - Some prior knowledge of the topic is helpful. ________________________________ As a reminder, the NGS Webinar Series the NGS Webinar Series <https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Flnks.gd%2…> hosts presentations on various topics related to NGS programs<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Flnks.gd%2…>, projects, products and services to educate constituents about NGS activities. * View our upcoming webinar schedule<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Flnks.gd%2…> * View recordings of previous webinars<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Flnks.gd%2…> * Have a question?
