S.A.T. Instruction Manual
* DO NOT ATTACH THE S.A.T. TO YOUR YAESU ROTATOR
UNTIL YOU COMPLETE THE CALIBRATION STEPS DESCRIBED
BELOW
Introduction
The S.A.T. is a novel and completely self contained device used to predict and track satellite passes
while simultaneously controlling an antenna rotator and tuning a transceiver. Once connected to
mobile device or computer through it's built it WiFi, all control is performed through any web
browser.
Get Familiar
LCD
The built in LCD displays information depending on the state of the S.A.T. For example, the IP address,
serial number and firmware version are displayed when the S.A.T. is idle. When actively tracking, the
satellite name, azimuth, elevation, range and range rate and AOS/LOS is shown. Other status message
are also available such as during TLE and firmware updates.

PORTS
The ports for connecting power, the rotator and your radio are location along to the top of the S.A.T.
Use the guide to identify the various connections.
RADIO CI-V CONNECTION
The RIG CONTROL port on your S.A.T. plugs into your radio with the provided Tip-Ring-Sleve cable.
Refer to the images on the right to find the CI-V or Remote jack on your radio. The correct jack has
been highlighted in violet.

ROTATOR CONNECTION
Plug the Mini-DIN connector into the S.A.T. and the full size DIN connector to the back of the rotator
control box. Refer to the image for the correct port.
* Do not connect the rotator until you read the calibration procedure below.

Apply Power and Boot
Attach USB
Your S.A.T. is powered by 5V through any standard USB port. Using the provided Micro-USB cable,
attached your S.A.T. to a USB port. Since the S.A.T. is an extremely low power device, almost any USB
power source will work including computers and laptops and of course, cell phone/mobile device
chargers.
The S.A.T. will immediately power on when power is applied.

The LCD will light up and the S.A.T. will beep once or twice while it's initializing.
Connect to the S.A.T.
Determine IP Address
During startup the S.A.T. will try to connect to a WiFi network if one has been configured. If it cannot
connect to a WiFi network then it will beep twice and start its internal WiFi Access Point. In this case
the LCD will display an IP address of 192.168.4.1.
Connect to the S.A.T. Access Point
Using your mobile device*, search for available WiFi network. If the S.A.T. is in Access Point mode then
an access point with the name CSN_SAT_XXXX will be available. The XXXX is the serial number of the
S.A.T. (older firmware versions had an access point name of Rotator_XXXX).
Connect your mobile device to that access point. (Some devices will complain that this access point
will not provide internet access. This is normal and you should allow the connection if prompted.)
* Any device that supports Wifi and has a web browser will work such as cell phones, tablets,
computers and laptops.

Open the Dashboard
Using your mobile device's web browser, navigate to the IP address displayed on the LCD screen. For
example: http://192.168.4.1
The S.A.T. dashboard will open on your device.

The S.A.T. Dashboard
The S.A.T. dashboard is seperated into four main areas.
Track Panel
While tracking, this panel displays essential satellite information and current antenna position
information. Current wind speed and direction is also displayed for your location.
Entering a satellite name or catalog number into the Name box and clicking Search will start tracking

the entered satellite, if it's found in the loaded TLE file.
The Satellite Status link will open the Amsat Satellite Status Page in a new window .
The SatNOGS link will open the excellect SatNOGS map for the currently tracked satellite.
Available Buttons:
NEXT PASSES - Predict and display current and future passes.
VIEW ALL - View the entire set of satellites stored in the S.A.T.
CONTINUOUS - Continue tracking the selected satellite even after LOS. A green button indicates
Continuous mode is active. A red button means Continous mode is not active.
SCHEDULE - Enable/Disable satellite schedule mode. See SCHEDULE section below for details.
READY - Move the antenna to the Ready position
PARK - Move the antenna to the Park position
ANT ENABLE - Enable or disable the rotator. Green to enable the rotator and red to disable. When
disabled, no movement commands will be sent to the rotator.
STOP - Stop all movement and tracking
Map & Chart Panels
Worldmap
This is a full color map display. With this style of display you can see the satellite location above the
Earth and it current track. In the lower left is a graphical display of the current antenna position.
In the bottom right of the map is a little icon that will toggle the ground track display on and off
when clicked.

Polar
The polar view takes some getting used to but contains a lot of useful information. The outer ring is
horizon and the center is directly overhead. North is towards the top. This display shows the satellite
track across the sky as well as the AOS and LOS azimuth and current antenna position. The color of
the track indicates if the satellite is in sunlight or shadow - yellow for sunlight and green for shadow.
The antenna indicator changes color if the rotator is in flipped/reverse mode - purple for reverse and
orange for normal. You can click and drag in that view to rotate the North orientation.
Ground View
This view simulates the observer standing on the ground and looking towards the satellite's current
postion. A compass is displayed along the bottom to indicate direction. With this view you can follow
a satellite as is rises above the horizon and travels across the sky until it sets. The track across the sky
is displayed as well as the current antenna position. The color of the track indicates if the satellite is in
sunlight or shadow - yellow for sunlight and green for shadow.

Radio Panel
Displays radio controls and available satellite transponders.
Top Row Buttons:
ENABLE - Enable or disable rig control. A Green button means the rig is enabled and will be
controlled. If red then it will not.
LOCK VFO - The S.A.T. keeps the uplink frequency in step with the downlink as you make changes
with the VFO knob. Disabling this lets you tune the downlink without affecting the uplink. (Generally
not needed if your radio has an RIT control).
CENTER - Sets the frequencies back to the transponder center frequencies. Basically resets any
changes you have made by turning the dial.
ADD - Allows you to add a transponder that is not listed.
Below the buttons are the radio controls:
POWER - Sets the radio power.
TBW - Sets the transmit bandwidth.
TX PL - Sets the TX PL tome.
MAIN - Sets the MAIN band mode.
SUB - Sets the SUB band mode.
The next area show the details of the currently selected transponder. The transponder name,
frequencies adjusted for doppler shift and curent doppler shifts are displayed.
Below the active area are the available transponders for the currently tracked satellite. Clicking on a
transponder name will make it active and will configure the radio modes, if the modes are known. In
the event that the SatNogs frequency is incorrect, you can change a frequency directly by clicking
directly on it.
