16 Satellite Users Conference 11 April, 2013 Non Export-Controlled Information Simulator Delivery and Training Approach Marlin Perkins of SPSD is the POC for simulator loans. Selection of order will be based on first come, first served, and customer readiness to receive units. Simulator will be shipped from the Omaha, Nebraska Harris facility. Upon arrival, Harris will provide a trainer who will assist in unpacking and training in use. The borrower will have a period of time with simulator, not to exceed 90 days. After completion, borrower will pack and ship simulator back to Harris in Omaha. Harris will receive simulator, re-baseline and make available to the next borrower. 16

17 Satellite Users Conference 11 April, 2013 Non Export-Controlled Information Summary GRB allows real time distribution of all Level-1b GOES-R data products for direct read out users. Direct Readout users need to upgrade their equipment for GOES-R: – Significant increase in data rate!!! – New data format!!! GRB down link specifications and data format specifications have been published. GRB simulators will be available in 2013 for Direct Broadcast reception equipment development and testing. Updates to be posted on the GOES-R web site: – 17

23 Satellite Users Conference 11 April, 2013 Non Export-Controlled Information HRIT/EMWIN Downlink Characteristics Coding – BPSK – Convolutional rate ½ code with constraint length 7 concatenated with Reed Solomon (255,223) with Interleave = 4. – Square Root Raised Cosine filtering using an Alpha factor of 0.3. – The resulting “Necessary Bandwidth” for this signal will be MHz. Modem Required The predicted C/No is in the range of 63 to 67 dB Maximum Demodulator Required – Eb/No is 4.6 dB for a BER of 1x10 -8 after decoding. Minimum Antenna System – At 5 degree elevation, the minimum antenna is 1.2 meter. – At 10 degrees or more elevation the minimum size is 1.0 meter. – Using a LNA or LNB with a system noise temperature of about 200 K will provide a G/T of 1.0 dB/K or -0.3 dB/K respectively. 23

24 Satellite Users Conference 11 April, 2013 Non Export-Controlled Information Planned HRIT/EMWIN Resources for Users Technology Demonstration Program GOES-R Program undertook a project to show that relatively inexpensive receivers designed for the new service could: – Support HRIT/EMWIN and all of the predecessor services – Software Defined Radio Receiver could consist of a modest amount of hardware (an antenna, low noise amplifier and a computer interface). – Design that is available to all users, hobbyist and manufacturers, with the software available to anyone at low or no cost. – Info on the GOES-R HRIT/EMWIN Users Page 24
