Course Description

This two and a half-day course is targeted at military operators, testers, and planners involved in specification, operations, planning, evaluation, testing, and use of military GPS user equipment. The course level assumes attendees do not have deep familiarity with satellite-based navigation (satnav) or GPS, or with electrical engineering principles and concepts. Important principles and concepts are conveyed without resorting to deep mathematics or theory. Extensive examples that employ simple back of the envelope calculations are used to equip attendees with the tools needed for understanding and assessing various aspects of military user equipment capabilities. Extensive use of practical examples allows attendees to apply the concepts in practice. Note: This course is restricted to employees of U.S. government agencies and their U.S. government contractors.

Materials You Will Keep

  • Electronic course notes in color, including review questions and solutions that will be addressed during the course, will be provided on a CD-ROM. Bringing a laptop to this class is highly recommended for taking notes using the Adobe Acrobat sticky notes feature; power access will be provided.
  • A black and white hard copy of the course notes will also be provided.

Book Allowance

  • Book allowances for on-site group contracts, if any, are negotiated as part of the contract. For your allowance, we encourage you to consider the new book by John Betz, Ph.D., Engineering Satellite-Based Navigation & Timing: GNSS, Signals, & Receivers, Betz. Wiley-IEEE Press, 2015.

Day 1 Morning

Introduction (1 hour)
GPS, satnav, and other current and prospective sources of position, velocity, and time, with their strengths and limitations. Shows why GPS and satnav will remain essential for decades to come.

Satnav and GPS Fundamentals (2 hours)

  • Basics of how satnav works. Construction of signals, receiver functions, jamming and spoofing, positioning and timing errors, GPS details including differences between civil and military signals, overview of foreign satnav systems.

Day 1 Afternoon

Military Signals and Receivers (1 hour)

  • Frequency bands, overview of P(Y) and M signals, binary offset carrier (BOC) spreading modulations, types of military receivers, receiver operating states, channel states.

Decibels (0.5 hours)

  • Refresher on decibels, dBW, dBm. Rules of thumb, examples, and tricks in using decibels for engineering calculations. Practical examples.

Receiver Performance Measures (1.5 hour)

  • Effective C/N0, spectral separation coefficients (SSCs), J/S, Eb/N0, tolerable jamming power (TJP). What they mean, why they are important, how they are interrelated, how they are used, with practical examples.

I appreciate the style of instruction Dr. Betz brings to the classroom. Very clear and easy to understand, willing to answer any questions and review class concepts or other concepts to establish foundation needed to understand class material. Dr. Betz presented a foundation of what the jamming side of the 746th Test Squadron works with and needs to understand in order to develop tests of devices under different types and conditions of jamming.

Dr. Betz was absolutely effective with well organized notes, good use of examples, nice balance between explaining different levels of materials.

I learned J/S versus TJP; best ways to stress ADAPs; best wave forms to stress receivers.

I am still incredibly new to the subject so I came in fairly blind, but I feel that the course was still excellent and gave me a great breadth of info from which I can now work forward.

I DEFINITELY recommend Course 335. It outlines much of what we do in our organization and how it impacts the world around us. Presents ideas of how to continue in an ever-changing technological world.

Course 335 is excellent for analysts and test managers. To gain an understanding of why things are done in a test and understanding when talking to analysts/interpreting results.

The end-to-end examples in 335 were extremely helpful and the topics leading up to them were set up well. I would recommend this course to our instrumentation engineers that work with the jammers, design and build them.
