Summary

Exciting new additions and updates with new material on Non-GEO and Q/V bands, which are hot topics Previously titled: Satellite Link Budget Training Using SatMaster Software.

Description

Link budgets are the standard tool for designing and assessing satellite communications transmissions at all orbits and frequencies, considering radio-wave propagation, satellite performance, terminal equipment, radio frequency interference (RFI), and other physical layer aspects of fixed and mobile satellite systems. Our principal software tool for this course is SatMaster Pro, a low cost application for Microsoft Windows. The format and content of the link budget must be understood by many engineers and managers with design and operation responsibilities. SatMaster is a highly-recognized yet simple to use PC-based software tool offered through the web by Arrowe Technical Services of the UK. This three-day course reviews the principles and use of the link budget along with hands-on training in SatMaster 10, the latest version, for one- and two-way transmission of digital television; two-way interactive services using very small aperture terminals (VSATs); point-to-point transmission at a wide range of data rates; and interactive communications with mobile terminals. Services at UHF, L, S, C, X, Ku, Ka, Q and V bands to fixed and mobile terminals are considered. The course includes several computer workshop examples to enhance participants’ confidence in using SatMaster and to improve their understanding of the link budgeting process. Participants should gain confidence in their ability to prepare link budgets and their facility with SatMaster. Examples from the class are employed as time allows. The course notes are provided. Have a Windows OS laptop in class with SatMaster 10 software. It can be purchased directly from www.satmaster.com (a discount is available to registered attendees).

The course notes are provided. All Virtual Live Webinar attendees must purchase and install the software prior to class.

Course Outline:

Day 1 Principles of Satellite Links and Applicability of SatMaster

  • Standard ground rules for satellite link budgets
  • Frequency band selection:, L, S, C, X, Ku, Ka, Q and V bands
  • Satellite footprints (EIRP, G/T, and SFD) and transponder plans; application of on-board processors (channelizers and regenerative repeaters)
  • Propagation considerations: the isotropic source, line of sight, antenna principles
  • Atmospheric effects: troposphere (clear air and rain) and ionosphere (Faraday and scintillation)
  • Rain effects and rainfall regions; use of the built-in ITU-DAH and Crane rain models
  • Modulation systems (QPSK, OQPSK, MSK, GMSK, 8PSK, 16 QAM, 32 APSK and higher)
  • Forward error correction techniques (Viterbi, Reed-Solomon, BCH, Turbo, and LDPC, turbo and concatenated codes)
  • Transmission equation and its relationship to the link budget
  • Introduction to the user interface of SatMaster
  • File formats: antenna pointing, database, digital link budget, non-GEO, and digital processing/regenerative repeater link budget
  • Built-in reference data and calculators
  • Example of a digital GEO one-way link budget (DVB-S2) using equations and SatMaster

Day 2 Detailed Link Design in Practice: Computer Workshop

  • Earth station block diagram and characteristics
  • Antenna characteristics (main beam, sidelobe, X-pol considerations, mobile antennas)
  • HPA characteristics, intermodulation and sizing, uplink power control
  • Link budget workshop example using SatMaster: GEO Single Channel Per Carrier (SCPC) with multi-carrier backoff
  • Transponder loading and optimum multi-carrier backoff; power equivalent bandwidth
  • Review of link budget optimization techniques using the program’s built-in features
  • Computing the uplink EIRP and transmit power; uplink power control (UPC)
  • Interference sources (X-pol, adjacent satellite interference, adjacent channel interference, co-channel interference from other beams)
  • Earth station power flux density limits and the use of spread spectrum for disadvantaged antennas

Day 3 Consideration of Interference, Non-GEO, and Workshop in Digital Link Budgets

  • C/I estimation and trade studies
  • Performance estimation for carrier-in-carrier (Paired Carrier Multiple Access) transmission
  • Non-GEO systems and how SatMaster can be used for “snapshot” analysis
  • Example: LEO link budget based on OneWeb system. Use of batch location files to prepare link budgets for a large table of locations
  • Case study from the class using the above elements and SatMaster
