  1. Communications: Technical Review February 5, 2013 Kevin Briglia Nathan Smith Pye Pye Zaw

  2. Technical Summary • Requirements • Updated requirements • Changes in requirements • Concept of Operations • Overview • Surface • Antenna Descriptions • S-Band • Ka-Band • Data • Storage • Compression • Power requirements

  3. Updated Requirements

  4. Changes in Requirements • Fundamental changes between preliminary and mature communication subsystem basic requirements include the following: • Generalization of implementation statements • Combination of similar requirement statements • Added verification and rationale statements to complement each requirement • Driving / stationary versus day / night • Direct to Earth

  5. Concept of Operations: Overview

  6. Concept of Operations: Surface Operations

  7. Antenna 1 • Ka-Band • High bandwidth • High gain • Highly directional • Steerable • Discrete transmission intervals • Large data packages • Heritage • MSL HGAS (X-band) • Scale for Ka-band • 6.6 kg gimbal • 1.4 kg array

  8. Antenna 2 • S-Band • Low bandwidth • Low gain • Omnidirectional • Transmits and receives continuously • Simple commands • Heritage • MSL RLGA (X-band) • Scale for S-band • 0.4 kg

  9. Data Compression mage compression comparison Data Storage • Data types • Images • Science Data • Telemetry • Transmission • Around or faster than 500 bps to 32 Kbps. Table 1. Comparison of file types and compression for images (Avosto).

  10. Power Requirements • Descent Stage • 175.2 W total • 11.4 W for X-band operations • Surface Operations • Up to 62.9 W total • 11.3 W for X-band operations • Heritage • MSL Specifications • Nominal Bus Voltage (28.0 V) • DC
