DCS (GOES Data Collection System)

• DCS receives a combined 34K messages an hour from our GOES-16 (East) and GOES-17 (West) satellites.

• DCS has several different mechanisms for data retrieval provide by NOAA.– DADDS (DCS Administration and Data Distribution System)– NWSTG (National Weather Service Telecommunication Gateway)– DOMSAT (Service ending 14 May, 2019)

– LRGS (Local Readout Ground System)– HRIT (High Rate Information Transmission)

LRGS Information

LRGS Information

LRGS Servers• There are several LRGS Servers. They are at

different locations across the country.

LRGS Monitoring GUI

User Account Setup

• Call a DCS operator at 757-824-7450 to begin the process for account set up.

• Have available the following:– Name– Email Address– Organization– Telephone Number– Preferred 6-character user name

Important Note

• Your DADDS account and your LRGS account are different.

• DADDS and LRGS are two separate systems and the usernames are not interchangeable.

User Account Set Up

• Must be a unique username.– We will check to see if you username is

available.– Currently, once you establish your password

there is no requirement to change it.– Once your account is established, it will be

immediately available on CDADATA. Your credentials will propagate to the other LRGS machines within 30 minutes.

Password Convention

• An initial password is generated by a GUI interface located at Wallops.

• The DCS operator will provide your new password over the phone.

• You may choose to keep this password or change it at you leisure.

• IT security requirements will not let us email you the password at this time.

Password Convention• NOAA CITR-021 Password Requirements

– Passwords must contain at least 12 non-blank characters– Password must contain 3 of the following four character classes:

upper case letters, lower case letters, digits, special characters.– Passwords cannot contain the user name or any dictionary word

or acronym that is 5 characters or longer– When changing a password, you cannot reuse any of the last 8

passwords, or any password that was set in the past 2 years.

Password Convention• Users can change their passwords if so desired.• The instructions are found in the Client User

Guide provided on the download page.• Additionally, we cannot see your password once

it has been initially created. If you forget, you will have to call the Wallops DCS help desk to have a new one created.

Downloads

• You do not need to login to your DADDS account to download the client

• Go to our web page for the download link• DCS1.NOAA.gov, DCS2.NOAA.gov• Download the user manual first and read

the particulars for your particular application

• Download the client software

LRGS Support

• Wallops has very limited support for LRGS• It’s a free OpenDCS suite developed to

give users another option for data retrieval.

• At Wallops we issue passwords for the system, keep the interface servers running and ensure DCS data is flowing to the LRGS’s.

LRGS Support

• Wallops staff does not help with installation of the client software. We provide a secure download of the latest client and user guides.

• Users should coordinate with their system administrator for installation help.

LRGS Support

• If you have detailed LrgsClient questions, contact Cove Software, LLC for specific application support. Cove’s phone number is listed in the last page of the user manual.
