Satellite Communications Training | Crash Course Description

Satellite Communications Training crash course focuses on satellite communications payloads, systems engineering and architecture of satellite systems including application requirements such as digital video and broadband media, mobile services, IP networking and UDP/TCP/IP services, concept of operations, identifying end-to-end.satellite payload requirements and constellation.

Customize It:

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.
