Worldwide Satellite Communication Services II (WSCS II)

Statement of Need

1. Introduction

The Office of Satellite and Product Operations (OSPO) is an organizational component of NOAA’s National Environmental Satellite, Data and Information Service (NESDIS). The OSPO has operational responsibility for the Satellite Operations Control Center (SOCC) at Suitland, MD and Command and Data Acquisition Station (CDAS) at Wallops, VA, and Fairbanks, AK to command and control the satellites, to track the satellites, and to acquire their data.

This contract provides communications services supporting the U.S. Polar Weather Satellite programs including the Department of Defense’s Defense Meteorological Satellite Program (DMSP); the Department of Commerce’s Polar-orbiting Operational Environmental Satellite (POES) systems, Geostationary Operational Environmental Satellite (GOES) systems and GOES Data Collection System (DCS); and, European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) Meteosat Second Generation (MSG) satellites Japan Meteorological Agency (JMA) Multi-functional Transport Satellite (MTSAT) satellites. This contract is administered by the General Services Administration (GSA), Federal Acquisition Service, Region 1, with the Contracting Officer Representative (COR) support coming from the Office of Satellite and Product Operations (OSPO), under the U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), National Environmental Satellite Data, and Information Service (NESDIS).

2. Scope

The communications services encompass all necessary ground segment terminals and the equipment and space segment assets to provide the links listed in Section 3, below, as well as in Attachment A. The existing data links supporting DMSP, POES, GOES, METEOSAT, and MTSAT for command and control and data routing to the data processing nodes and user communities are set forth in the Attachments. The required services are “turn-key” command and control and Data Routing and Retrieval (DR&R) communications systems, services, and maintenance. Turn-key services comprise all segments of the infrastructure required to relay the data from the Data Stream Sources to the Data Stream Destination Sites, including; proposed fiber relay systems, proposed satellite uplinks (e.g., ground station facilities and associated electronics), the domestic satellite transponders, and the satellite links to users either directly or through a teleport facility, including all equipment necessary at the users’ site.

A multicast link with simultaneous broadcast capability to multiple users (see Figures 1, 2, 3, 4 and 5 in Attachment A) is highly desirable. This desired capability applies to all links. All services being offered shall include, within its “turn-key” definition, all necessary user site equipment, including maintenance and support. Services for all links shown in Figures 1, 2, 3, 4 and 5 in Attachment A shall be fully operational and begin service not later than August 1, 2014.

Circuits are required to support the operational DMSP, POES, GOES, METEOSAT, and MTSAT satellite constellation, as well as services that include, but not limited to METEOSAT and the GOES Data Collection System (DCS). Command & Control links and data links shall be relayed/transmitted in real-time, from the remote ground stations to the customers’ processing and exploitation locations, (e.g., NESDIS, Air Force Space Command (AFSC), Air Force Weather Agency (AFWA), and Fleet Numerical Meteorological and Oceanographic Center (FNMOC), etc.). Data paths, service point locations and data rates are identified in Attachment A, as well as in Section 3, below. There is a requirement that the GOES DCS DOMSAT Ku- Band service, currently transmitted from the Wallops CDAS, maintains compatibility with the DCS DOMSAT receive systems in the field. The RF and data protocol specifications needed to ensure the backwards compatibility with the DOMSAT user receive terminals, which are not a part of this procurement, are identified in Attachment B. There is also a requirement to assume the maintenance responsibilities for a GFE receive antenna, located in Kaena Point, HI;

maintenance specifications are identified in Attachment C.

The GOES DCS DOMSAT Ku-Band Link Requirements

Primary Site - Wallops CDAS, Va.

Backup Site – Suitland NSOF, Md

The GOES DCS DOMSAT link provides a communication service as a point-to-multi-point simplex 56kbit single channel satellite service operating over the Ku-band. The communication service shall be provided to operational downlink sites (the downlink sites already exist and are not a part of this procurement) located within the 48 contiguous states and shall require no modifications to either the software or hardware at these downlink sites. Each downlink site has a

Prodlin 1.8 meter antenna connected through a low-noise block down converter (LNB) to a

ComStream DBR401 demodulator (or equivalent, e.g. the Adaptive Broadband SDM-300L which is a plug-in replacement for the ComStream DBR401 in the existing downlink sites). The communication service must also support the data transfer protocol currently being used (see

Appendix X).

The data to be broadcast will originate at the NOAA/CDA Station at Wallops Island, Virginia, and so all transmission equipment must be located and maintained there. A downlink receive system is required at the NOAA/CDA station for monitoring the performance of the uplink.

Performance

The RFQ BER requirements shall apply to the 1.8m DCS receive antenna system.

Current DCS DOMSAT RF Parameters

1. Circuit#: 8819

2. Data Rate: 56 Kbps

2. Satellite: SES-1, Located at 101deg West

3. Satellite transponder: Ku Transponder 14

4. Downlink Frequency: 11997.525 MHz

5. Downlink Polarity: Horizontal Polarization

Backup Service

The current DCS DOMSAT system provides for a backup DCS DOMSAT transmit/ receive antenna system located at the NSOF in Suitland, Md. location. This system functions as a backup to the Wallops primary system and operates over the same satellite link, transmit frequency and with the same availability as the Wallops system. The Contractor shall be responsible for enabling or disabling the transmitters at either site, within 15 minutes following a request from NOAA..

GOES Data Collection System (DCS) Domsat Data Stream Format

DOMSAT is a point-to-multipoint broadcast, and thus no responses are sent from the receiver to the broadcaster. Three nested protocols are used to transfer DOMSAT messages. The broadcast data are encoded using:

1. HDLC Lap-B frame

2. X.25 Information Packets

3. Custom DOMSAT Message Protocol

4. DOMSAT Packet

5. DOMSAT Message

The figure on the following page illustrates the nesting. This figure is followed by a description of each layer.

1. HDLC (LAP-B) Frames

Frames are encoded using a non-standard subset of HDLC LAP-B.

The HDLC address field must always be 1 (or error is assumed and packet is ignored).

The HDLC Control field must always be 0 (or error is assumed and packet is ignored). The high-order bit being 0 indicates that only HDLC information frames are broadcast. Note that the

3-bit sequence number fields and the poll/final bit are always 0. The receiver should not attempt to perform sequence checking or any other processing using these fields.

Zero-bit insertion is used (standard HDLC) and a standard CRC16 is contained in the last two bytes of data.

Each HDLC frame contains an X.25 Packet with a maximum length of 256 bytes.

2. X.25 Packets

Packets are encoded using a non-standard subset of X.25.

The first byte contains various flag bits and a group number. This byte will always have a value of 0x10 (or error is assumed and packet is ignored).

The high-order bit (bit 7) contains 0, meaning that only data packets are sent (never an interrupt packet or a control packet)

Bit 6 always contains 0. No processing should be done on this bit.

Bits 5 and 4 always contain 01, indicating that a single byte follows the channel number containing sequence numbers and the 'more bit'.

The low-order 4 bits always contain the group number 0.

The X.25 channel field will always be 0. Combined with the 0-group number this means that all data travels on logical circuit 0.

The 3rd byte contains receive/send sequence numbers and the 'more bit'. The sequence numbers are always 0. The receiver should not attempt to perform sequence checking using these values.

The 'more bit' (bit 4) is used to indicate the end of a complete DOMSAT message:

More=1 means that the message is not yet finished. The receiver should expect more packets to construct the complete aggregate message.

More=0 means that this is the last packet for a DOMSAT message. The receiver can now process the complete message.

Each X.25 packet contains one DOMSAT packet with a maximum length of 253 bytes.

3. DOMSAT Packet Protocol

a. DOMSAT Packet

Each DOMSAT packet starts with a 2-byte (16-bit) message sequence number. The number is big-endian (i.e. the first byte is the high-order byte). In general, sequence numbers increment with each complete DOMSAT message (which may be composed of multiple packets).

Individual packets within a message will have the same sequence number.

Following the message sequence number is a single byte containing:

A 'Retransmitted Message' Flag (high bit).

A seven-bit packet sequence number.

The packet sequence number starts at 1 for the first packet within each message and increments until the complete message is received. There can be a maximum of 64 packets making up a complete DOMSAT message. Hence the largest

DOMSAT message can by 64 packets times 250 bytes per packet equals 16000 bytes.

The Retransmitted-Message flag is 0 if this is the first time that this message has been transmitted over DOMSAT. It is 1 if this message has been previously transmitted. Messages are retransmitted in response to a manual user request.

The 16-bit message sequence number starts with 0 (when DAPS is re-booted or a fail-over occurs) and continues to increment. It wraps from 65,535 to 0 and continues to increment.

A DOMSAT packet contains up to 250 bytes of DOMSAT message data.

b. Complete DOMSAT Messages

A complete DOMSAT message is constructed by concatenating the data fields of successive

DOMSAT Packets. The maximum message size (imposed by NESDIS, not by the protocol) is

16,000 bytes.

DOMSAT messages begin with a 37 byte ASCII text header followed by variable length data.

The header has the following structure:

8 hex digit DCP Address

YYDDDHHMMSS - Time the message arrived at the Wallops receive station. The day is represented as a three digit day of the year (Julian day).

1 character failure code

2 decimal digit signal strength

2 decimal digit frequency offset

1 character modulation index

1 character data quality indicator

3 decimal digit GOES receive channel

1 character GOES spacecraft indicator ('E' or 'W')

2 hex digit uplink carrier status

5 decimal digit message data length

The NOAA MTSAT Antenna Maintenance Requirements

Kaena Point Air Force Base, Hi

NOAA/NESDIS has installed an antenna ground station at the Kaena Point Air Force Base, Oahu, Hawaii, to receive L-Band data from the MTSAT, a Japanese geostationary satellite located at 140 degrees east. The MTSAT data is received and then provided to the Kaena Point DOMSAT facility for transmission to the Continental United States, through a 3.5 MBPS service (current circuit

#50372A) To ensure reliable operation of the NOAA MTSAT ground station data downlink, antenna maintenance has been provided by a contractor, through an annual support contract. Responses to the

RFQ shall propose annual support for this antenna, as an option.

The NOAA MTSAT ground station component specifications to be considered in the proposal are:

- 3.8 meter Patriot antenna receive system, model PRT-380AZKP. Antenna is fitted with

Quorum L-Band .38 Scalar Feed: part no. 990005903. Mounted to the feed is a Quorum

LNB ESD 1691.0-137.5: part no. 990005501. Connecting the downconverter signal to the receivers and providing power to the LNB are two 150 foot runs (one spare) of Belden 9913F

RG6 coaxial cable. The primary cable also provides DC power to the LNB that originates in the MTSAT receiver. Mounted between the LNB and the RG6 cable is a lightning protection device, Polyphaser Model RGT Gas Tube. Lastly, there is a Quorum MTSAT receiver, part

no. 990009425.

The following antenna maintenance services are to be included in the proposal:

- A 24x7 Help Desk including phone support in the event of a MTSAT data interruption or degradation observed at the user end

- On-site dispatch to make necessary repairs and restoration of service at a best effort basis

- Regular antenna re-points to achieve optimum reception of signal from the MTSAT spacecraft

- Capability of performing remote diagnostics to routinely check antenna equipment specifications

- Replacement of faulty antenna components as soon as possible using accessible spare parts inventory locally at the site

- Required performance specifications are:

o The bit error rate is no more than 1X10^7 over 24-hours o Quality data to be available at a minimum of 99.5% (based on nominal MTSAT dissemination schedule) of the time
