4 Background Current Direct Readout Services:
Automatic Picture Transmission (APT) Service Analog service operational on POES spacecraft Service available through the life of legacy spacecraft Low Resolution Picture Transmission (LRPT) EUMETSAT replaced analog APT with the digital LRPT on Metop-A LRPT on Metop-A interfered with the sounder, turned off in 2007 LRPT is not available on Metop-B/C High Resolution Picture Transmission (HRPT) Digital service operational on POES spacecraft Advance High Resolution Picture Transmission (AHRPT) EUMETSAT replaced HRPT with the AHRPT with Metop-A Metop-A AHRPT service limited operation since 2007 Metop-B AHRPT is full global operation

6 Service Availability APT HRPT LRPT AHRPT LRD HRD POES YES NO Metop Meteor M FY-3 S-NPP JPSS-1 NO* JPSS-2 *Development of an LRD service on JPSS-1 was suspended in Currently, JPSS is not planning to implement L-band capabilities on JPSS-2 and beyond and is studying the impacts on users.

7 APT Service Service Transition
APT service WILL BE available until end-of-life of POES spacecraft , NOAA’s future polar-orbiting satellites will NOT support an APT or APT-like service, A likely alternative is the Low Resolution Picture Transmission (LRPT) service Available on Roshydromet Meteor-M/MP series satellites Use of the MHz frequency band on future NOAA polar-orbiting satellites has not been considered.

8 HRPT Service Equipment
1.1 meter (or larger) parabolic dish Antenna positioner and control hardware including azimuth and elevation rotators Feedhorn and quadrature combiner Low noise amplifier Wide band receiver Demodulator Bit-synchronization board Personal Computer Software for image ingest, processing, and display Cost Complete system: $50K+ (USD) Visit any satellite receiver manufacturer See NOAASIS/ml/manulst.html for list of vendors The HRPT service will be continuous through the end-of-life of the POES spacecraft.

9 Summary of JPSS Direct Readout Plan
JPSS Level 1 Requirement document provides the basis for the planned support of the direct readout community with direct broadcast from JPSS-1 and JPSS-2 JPSS-1 will provide HRD (High Rate Data) broadcast containing sensor data JPSS-2 will provide HRD broadcast and the NOAA JPSS Office will finalize decision to not implement LRD (Low Rate Data) broadcast after studying user impacts. The JPSS HRD broadcasts (JPSS-1,JPSS-2) will contain all of the sensor data necessary for the field terminal user community to produce a full set of data records (Mission Support Data will be available by internet) Any potential JPSS-2 LRD broadcast would contain the necessary sensor data for the field terminal user community to produce a prioritized set of data records

10 Summary of JPSS Direct Readout Plan (con’t)
JPSS will not perform encryption of the direct broadcast JPSS will provide the necessary inputs (for the field terminal user community to produce the data records) on a web portal Algorithms & Software, Data Processing Framework, Mission Support Data (MSD), Field Terminal Hardware Specifications, Test Products Users will be notified of any updates to these products Software and algorithm updates are JPSS configuration control board (CCB) managed JPSS will provide additional services to the field terminal user community HRD downlink status (post-pass) & mission status notifications Help desk for user support (TBD)

12 High Rate Data (HRD) Service (con’t)
Registration of X-band Stations The X-band range (7.75 – 7.90 GHz) is shared between Meteorological Satellites and Point-to- Point Radio Links on ground. To protect against Potential Interference from Point- to-Point Radio Links it is strongly recommended to register X-band Direct Readout Reception Stations with the national Radio Frequency Authorities; Before selecting a location for a new X-band Direct Readout Reception Station it is advisable to carry out a Radio Frequency Survey to identify any existing sources of interference.

13 High Rate Data (HRD) Service
Equipment Cost X-band only $250K+ (USD) L-band/X-band $400K+ (USD) Equipment Information Visit any satellite receiver manufacturer See NOAASIS/ml/manulst.html for list of vendors The HRD service will be continuous through S-NPP and JPSS-1/2. A HRD service will be available on several future international polar-orbiting constellations. See

14 Low Rate Data (LRD) Service
Equipment Equipment Configuration Similar to Metop AHRPT terminal Data Format CGMS Global Specifications for AHRPT Cost LRD $100K+ (USD) An L-band service will not be available on S-NPP and JPSS-1. EPS-SG has excluded the transmission a (very) reduced amount of data in L-band in parallel, for cost reduction and performance reasons. The 1695 – 1710 MHz band covering the US states will be shared with commercial broadband services.

15 HRPT Transition Transition to HRD
It will not be possible to upgrade an existing HRPT station to use the S-NPP/JPSS HRD Old equipment not compatible Requires a new X-band field terminal Other systems that don’t meet those requirements Replacement of demodulator and potentially other components; Software upgrades to handle S-NPP/JPSS instrument data and other S-NPP/JPSS specific aspects Station Cost X-band only $250K+ (USD) L-band/X-band $400K+ (USD) System information Visit any satellite receiver manufacturer See /manulst.html for a list of vendors The meteorological X-band (7.75 – 7.90 GHz) has been selected for EPS-SG direct broadcast. .

16 HRPT Transition Transition to LRD Equipment Upgrades Data Format
Similar to HRPT to Metop AHRPT upgrades Data Format CGMS Global Specification for AHRPT Station Cost L-band only $100K+ (USD) L-band/X-band $400K+ (USD) Equipment Information Visit any satellite receiver manufacturers See manulst.html for a list of vendors

17 Summary A summary of the spacecraft services and field terminal changes are listed below: METOP Constellation LRPT: APT Service replaced the failed LRPT in the AM orbit; LRPT is not available on METOP-B/C; AHRPT: New format requires upgrades to existing HRPT field terminals or purchase new station. POES Constellation APT: Frequency change in the – MHz frequency band; HRPT Service remains unchanged; APT/HRPT services are available until POES end-of-life. S-NPP/JPSS Constellation APT service will not be available; HRPT will not be available and might be replaced with the LRD broadcast, which would require L-band field terminal upgrades; LRD will not be available on S-NPP or JPSS-1; a final decision on JPSS-2 will be made after studying the impacts of no LRD on users. HRD service requires a new X-band field terminal.

18 Summary of Direct Readout Services
Satellite/Series Time Period Type of Service (1) Frequency Band Nominal Freq Range & Data Rate NOAA 1983 – 2013+ APT VHF 137 MHz; 33 Kbps HRPT (3) L-band 1698, , or 1707 MHz; 665 Kbps METOP-A/B present AHRPT (3) 1701/1707 MHz; 3.5 Mbps LRPT 137/139 MHz; 75 Kbps S-NPP present HRD (2) X-band 7812 MHz; 15 Mbps JPSS-1 FF-1 A-DCS 1705 MHz; 1.5 Mbps JPSS-2 LRD (TBD) 1703 MHz (TBD); 3.8 Mbps 1. All services are Digital, except NOAA APT which is Analog Contains Full Resolution Imagery Data 3. L-band Full Resolution Imagery ends with NOAA-19 circa 2013, but continues with METOP-B. Data rate for METOP-C is uncertain. User impacts of no L-band service on JPSS-2 and beyond are requested.
