When a satellite rotates around Earth at the same rate it rotates giving it a "fixed" location in the sky from a ground station.
What is Geo-Synchronous Orbit?
100
This device amplifies the signal and downconverts it to L-Band.
What is the LNB
100
This light blinks when it has Rx Lock and is lit solid when it has Tx Lock.
What is the SAT light?
100
This is powered on after the circuit breakers during the power on procedure.
What is the UPS?
100
This is the direction the trailer should face when setting up.
What is the equator?
200
Type of polarization used in Ka frequency band.
What is Circular?
200
This device displays the signal in a graph format, power by frequency, for the purpose of analysis.
What is spectrum analyzer?
200
Direct connections between Traffic Terminals (TTs) in the Linkway network allowing the passage of data communications without the need for Hub-routing.
What are Permanent Virtual Circuits (PVC)?
200
This is used to determine how level the STT is.
What is the bubble level (or ACU tilt screen)?
200
This is centered on the spectrum analyzer to to prove you're on the satellite.
What is the beacon frequency?
300
Varying one or more properties of a medium to encode information onto it.
What is modulation?
300
This device is utilized to manipulate the direction of the antenna.
What is Antenna Control Unit (ACU)?
300
This burst begins network synchronization, establishes a timing reference, and tells traffic terminals when the Acquisition Burst slots are.
What is the Reference Burst?
300
These are the steps to load the bootfile into the Linkway modem.
From the TDMA screen -> Browse -> Locate and Select Bootfile -> OK -> Load Bootfile
300
This is used to get the information about the satellite and to configure the FDMA modem.
What is the Satellite Access Authorization (SAA) or a cutsheet?
400
Three bits of data are represented per symbol in this type of modulation.
What is 8PSK?
400
This device is connects nearly all equipment to the laptop for monitor and control.
What is the Port Server?
400
Representation of signal quality by dividing the number of error bits received by the total amount of bits received.
What is Bit Error Rate (BER)?
400
The frequency entered into the Linkway modem when the SAT controller gives you a frequency of 14.32175 GHz during peak and poll.
What is 1271750000 (1.27175 GHz)?
400
Programmed into the ACU, used to locate satellites, displayed as signal strength.
What is the beacon frequency?
500
Frequency manipulation via a mixer is a process known as this.
What is heterodyning?
500
This device combines and divides L-Band signals.
What is the IFSPU?
500
The Linkway modem is considered transmit sync'd when three of these bursts are received in the correct time slots.
What is the Acquisition Burst?
500
The receive IF frequency of the transmitted IF frequency of 1150 MHz.
What is 1150 MHz?
500
RxRFFreq field in the bootfile tells the modem to find this.
