Gpredict.

This seems one of the few Satellite control/prediction systems that is Open-Source (which is a shame), but it is a nice program and has been around for some time.

I will not bother selecting Satellites, updating TLE's etc - as there is plenty of help for this.

Configuring Radio Access

In the

• Edit

  • Preferences
  • Interfaces

  Add you Radio Name. Now important thing to note, the IP Address is not the IP Address of the Radio, but the IP Address of the rigctld machine.

  I entered the following

  • ConfigName EB200
  • Host localhost
  • port 4522

And that was it. Note the values localhost and port (4522) you tested earlier.

At this point you need to select your next Satellite to work, and Select Radio-Control from a menu option.

I then Engage the Radio-Control

IC 7000 Settings

Find the Model number

 rigctl -l | grep 7000

And I see

   340  Icom                   IC-R7000                0.7.0           Alpha
   360  Icom                   IC-7000                 0.7.2           Beta

OK so it is the IC-7000 - model 360.

Lets Test we can talk to it

 rigctl -m 360  -r /dev/cu.usbserial-FTDE0JY3 -s 19200

Now type f which means What frequency are you on ?

If we get the frequency on the screen .. things are looking good.

We now need to add RigCtrl-D - the Daemon, network protocol.

Testing

To start the controller then we do ...

rigctld -m 360  -r /dev/cu.usbserial-FTDE0JY3 -s 19200 --port=4532

This means we are listening on port 4532 - and will accept any IP Address.

To test this ...

 echo "f" | nc -w 1 127.0.0.1 4532

And you should see the escaped frquency. And everything is OK....

TRSP

If you select a SAT and it does not have a transponder settings (for Ham 99% are like this)

Do not fear this is what a TRSP file looks like

[Mode V Digitalker (Voices Messages and Telemetry)]
DOWN_LOW=145950000
MODE=FM

[Mode V Imaging (Robot 36 SSTV from onboard cameras)]
DOWN_LOW=145950000
MODE=SSTV in FM carrier

[Mode V Telemetry (1000 baud (400 baud backup))]
DOWN_LOW=145920000
MODE=BPSK 1000 bps

[Mode U/V (B) Linear Transponder]
UP_LOW=435742000
UP_HIGH=435758000
DOWN_LOW=145922000
DOWN_HIGH=145938000
INVERT=true

[Mode V TLM Beacon (CW-2, BPSK-1000)]
DOWN_LOW=145919000
MODE=CW

[Mode V TLM Beacon (CW-1, BPSK-400)]
DOWN_LOW=145939000
MODE=CW

It needs to be named NOAA-Number.tsp i.e. 123456.trsp

and placed in ~/.config/Gpredict/trsp
