1616

❖ Telemetry receiver requirements and features described in this presentation are not

necessarily in every industry receiver, and final receiver requirements must be tailored to

each customer’s unique specifications

❖ Critical receiver parameters applicable to every telemetry receiver include:

- Front End RF filtering and signal conditioning for optimum NF, ACI and Spurious

Response

- IF filtering (SAWs and FIRs) for capturing 99% of bandpass energy and optimized

rejection of unwanted IF signals in the bandpass

- Linear, precise and scalable AGC outputs matching receiver dynamic range and antenna

tracking interface, with fast AGC time constants for optimum data quality and slower AGC

time constants for antenna tracking

- Linear 70 MHz IF outputs for antenna G/T measurements (analog 70 MHz preferable)

- Multi-Mode FPGA demodulator with AGC, dynamic range input and baseband FIRs that

provides BER performance per IRIG

- AM outputs with selectable output impedance and low pass filtering for optimum

processing of antenna error correction signals

❖ Other receiver features (Diversity Combiner; Pre-d record and playback; 70 MHz playback;

AE; DQM; FEC decoders; STC; eye, constellation & spectral displays; bit sync; frame sync;

BERT; PN Generator; BIST and TMoIP) are becoming more and more the norm as a

function of ongoing Range Modernization programs and emerging technologies

R300 SERIES TELEMETRY RECEIVER FEATURES v Non-Windows OS

o NASA Spread Spectrum o Adaptive Equalization o Data Quality Encapsulation/Metric o SOQPSK-STC & SOQPSK-LDPC

v Built-In-Self-Test (BIST) with Bit Sync/Frame Sync and BERT v Multi-Channel TM over IP v Dual 7” Touch Screens for Command and Status v Dual Redundant “Hot Swappable” Power Supplies

v Fully Compatible with all SEMCO Legacy Receivers

DESCRIPTION - SEMCO's 3U R300 Series Telemetry Receivers are IRIG 106-‐17 Tier II phase noise compliant and offer state-‐of the art demodulation capabilities in RF tuning bands from 70 MHz to 5250 MHz. The R300 is fully compatible with and designed to operate side-‐by-‐side SEMCO legacy receivers. Built-‐In-‐Self-‐Test (BIST), Bit Sync/Frame Sync/BERT – The BIST provides for an embedded P/L/S/C Band RF source and, when coupled with the embedded bit sync/frame sync/BERT and PN Generator, provides for BER and other critical IRIG 118 testing, + background health and diagnostics testing. STC & LDPC Feature -‐ SEMCO’s current demodulator technology is supports all current IRIG modulation modes, including Space Time Coding (STC) & Low Density Parity Check (LDPC). STC is offered in SOQPSK-‐STC format, while SOQPSK-‐LDPC FEC includes user-‐selectable IRIG block sizes, coding rates and both IRIG and CCSDS de-‐randomization. Adaptive Equalization and Data Quality Encapsulation/Metric -‐ Additional R300 Series features include Adaptive Equalization (AE) f o r improved receiver performance in selective multi-‐path environments; Data Quality Encapsulation (DQE)/Data Quality Metric (DQM) supporting Best Source Selection by embedding data quality information within PCM/FM and SOQPSK-‐TG formats; as well as true analog I and Q outputs for BSS applications NASA Spread Spectrum Capability – Constellation program crew vehicle support including the Forward SS-‐UQPSK link and the Return DG1 Modes 1, 2 & 3 links. TM over IP – Multi-‐CH TM over IP provides IRIG 218 or CH 10 compatible packetized baseband video data via Ethernet. Operating Environment and IA Compliance -‐ The R300 uses a hardened operating environment and “DMZ Buffer” design technology (Ethernet-‐to-‐Serial Adapter with Secure Shell (SSH) protocol) for secure Ethernet connection to isolate the embedded ARM Processors from the outside world. This ensures DSIA IA compliance. However, migrating to this environment does not limit the abilities of the local or remote user. Remote control via Ethernet is still available and using optional AES encryption on the remote message data can provide additional enhanced security. Local and Remote Control Features -‐ Local control has been enhanced by the use of dual 7” LCD touch screens. The user can always view status and configuration of the unit while controlling options and set-‐ups using the second touch screen for data entry. Eye Pattern, Constellation and Spectrum displays are available while the unit is operating. Remote (Network) control capability is available using the System Level Telemetry Software (SLTS) Program.

Conversion and Upgrade of Legacy SEMCO Telemetry Receivers To the Next Generation 3U RC300-2 Receiver

SEMCO is actively engaged in several major telemetry receiver conversion and upgrade programs at several U.S. Flight Test Ranges. These ranges have been successfully supported by SEMCO legacy telemetry receivers for the last 20+ years, and their design architecture supports the ability to be converted and upgraded to SEMCO’s next generation, fully IA compliant non-Windows-based RC300 Receiver. Importantly, this conversion and upgrade is accomplished at 1/2 to 2/3 the cost of a new receiver, resulting in substantial savings to the ranges. This conversion and upgrade include the latest IRIG features and performance demanded by current and emerging telemetry technologies and requirements, as well as additional advanced features developed by SEMCO. Each range selects from the following features and technologies based upon their defined requirements: • RF Tuning (200-1150, 1415-2485 and 4400-5250 MHz) • 16 IF SAW Filters with 8 IFBW values (300 kHz to 40 MHz) + 15 IF FIR Filters per data rate/demod + Auto • 15 Baseband FIR Filters + Auto presented to the user as a function of data rate input and demodulator format • 3 user-switchable analog and digital demodulators, each with 6 outputs (2 analogs, 1 Clock, 3 Data) • PCM/FM, NTSC Video, legacy (PM, BPSK and A/U/S/O/QPSK), IRIG 106-19 Tier 0 Trellis FM, Tier I SOQPSK-

TG and Tier II Multi-h CPM, PM/PSK (SGLS) and FM/FM Subcarrier, FM/FM Sub-carrier, GMSK, Spread Spectrum and Coherent AM demodulation

• Multi-channel Embedded Stand-Alone Bit Sync/Frame Sync/BERT/PN Generator with int. and ext. switching • 3 Channel IRIG 218 and CH10 TMoIP • Adaptive Equalization (AE) and Data Quality Encapsulation/Metrics (DQE/DQM • Low Density Parity Check (LDPC) and Space Time Coding (STC) • Viterbi and Turbo Forward Error Correction (FEC) • Built-In-Self-Test with embedded Modulated RF BIT Source/BERT • 2 scalable AGC outputs and 1 AM antenna tracking output per channel (CH1/2 and Combiner) • Eye Pattern, Constellation, Spectral Sweep and Eb/No displays for each installed demodulator • Both Local GUI control and remote control via Ethernet. • A user-switchable 70 MHz Playback feature + Multi-channel pre-d recording and playback (75 kHz to 15 MHz) The RC300A-2 has two 7” touch screens for control and display, dual redundant power supplies, local GUI interface control and remote (network) control using its own fully IA-compliant, non-windows-based embedded LINUX ARM processors. The RC300-2 is fully compatible with all functional and operational interfaces currently employed at the Flight Test Ranges, and the rear panel design and reference designators are fully compatible with the convention currently employed in all TM ground station receiver installations.
