  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 • Service available through the life of legacy 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

  5. Characteristics

  6. Service Availability *Development of an LRD service on JPSS-1was suspended in 2011. 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 Use of the 137 -138 MHz frequency band on future NOAA polar-orbiting satellites has not been considered. • 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

  8. HRPT Service The HRPT service will be continuous through the end-of-life of the POES spacecraft. • Equipment • 1.1 meter (or larger) parabolic dish • Antenna positioner and control hardware including azimuth and elevation rotators • Feedhornand 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 http://www.noaasis.noaa.gov/ NOAASIS/ml/manulst.html for list of vendors

  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)

  11. Summary of JPSS Direct Readout Plan (con’t) The key differences in the mission architecture from S-NPP are in bolded text below SMD - Stored Mission Data, HRD – High Rate Data, T&C – telemetry and Command,

  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 • 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 http://www.wmo.int/pages/prog/sat/satellitestatus.php • Equipment • Cost • X-band only $250K+ (USD) • L-band/X-band $400K+ (USD) • Equipment Information • Visit any satellite receiver manufacturer • See http://www.noaasis.noaa.gov/ NOAASIS/ml/manulst.html for list of vendors

  14. Low Rate Data (LRD) Service • 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. • Equipment • Equipment Configuration • Similar to Metop AHRPT terminal • Data Format • CGMS Global Specifications for AHRPT • Cost • LRD $100K+ (USD)

  15. HRPT Transition The meteorological X-band (7.75 – 7.90 GHz) has been selected for EPS-SG direct broadcast. . • 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 http://www.noaasis.noaa.gov/NOAASIS/ml /manulst.html for a list of vendors

  16. HRPT Transition • Transition to LRD • Equipment Upgrades • 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 http://www.noaasis.noaa.gov/NOAASIS/ml/ 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 137.1 – 137.937 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 User impacts of no L-band service on JPSS-2 and beyond are requested.
