6A Flashcards
___ ___ is the result of successfully connecting two or more satellite terminals where data or voice orderwire are passed over a satellite channel without significant degradation.
Link establishment
This is the first step in establishing a link.
Satellite tracking
In order to move on to transmitting and receiving frequencies we need to make sure that we are aimed at our assigned satellite. There are a number of tracking principles that can be utilized by antennas, but what’s important is that we are peaked on the ___ ___.
satellite’s downlink
The most efficient way to ensure we are peaked on a satellite’s downlink is to lock onto the satellite’s ___.
beacon
One purpose of a ___ is to serve as a basic identification mark to let you know you are on the correct satellite.
beacon
Once you have moved your antenna in azimuth and elevation to find the satellite, you can verify that you are on the right satellite by using the ___ and a ___.
beacon
spectrum analyzer
Once the beacon is found, many systems have ___ ___ ___ to lock onto the satellite’s beacon.
automatic tracking systems
A ___ uplink and downlink happens once we are peaked onto the satellite’s location.
nominal
This is where we can successfully acquire a communications channel using transmit and receive principles without error.
Nominal Uplink and Downlink
___ is the transmit signal we are sending from our terminal.
Uplink
___ is what we are receiving from the satellite
Downlink
In order to ensure that our uplink and downlink is ideal, ___ ___ must take place.
power balancing
This takes place following a successful communications link that is established over a
satellite connection.
Positive Control
Positive control takes place following a successful communications link that is established over a satellite connection. Actions that take place during this phase of link establishment are required link status reporting and…?
Authorized Service Interruptions (ASIs)
ASIs are ___ link outages that are either performed by the STEP site or at the user’s terminal.
scheduled
