Spacecraft RF Communications Training
Spacecraft RF Communications Training Course Description
This three day Spacecraft RF Communications Training is intended for practicing systems engineers who want to learn how to apply model-driven systems Successful systems engineering requires a broad understanding of the important principles of modern spacecraft communications. This three-day course covers both theory and practice, with emphasis on the important system engineering principles, tradeoffs, and rules of thumb. The latest technologies are covered.
This course is recommended for engineers, managers, and scientists interested in acquiring an understanding of satellite communications, command and telemetry, and tracking. Each participant will receive a complete set of notes.
Important systems engineering principles and latest technologies for spacecraft communications.
Design drivers for today’s command, telemetry, communications, and processor systems.
RF link budgeting principles.
Important effects of noise, radiation, bit errors, and spoofing.
Low noise receiver analog and digital design
Error control channel coding
Application of Kalman filtering to spacecraft tracking.
Satellite types and configurations
With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
