Excellent program. I will be using it in a ham radio training course and with students in a ham radio club at school. We hope to be able to apply for and be granted an ISS scheduled contact. Your program will be used for some of the science projects leading up to the application and, if granted, to control the radio(s) and rotor during the contact.

What map projection is the program coded to use? I have several .bmp images of world maps (high resolution with political boundries) but they do not give the same relative image as the maps you have available.

YOU RULE!! Really a great program! I know you don't ask for money in return but as soon as I can, (I'm on a fixed income and disabled) I intend to send a few bucks to you for the cause:-) I sent a post card from Virginia USA today.

Like the look of the program, but, when looking at ISS I get different results to NASA's realtime tracking map. Which is right?

It would be nice to have Orbitron translated to... Os X for Mac users. No more emulators, please.

is it possible to run more than one driver as an DDE client ?
I have a running rotor-control driver and I need another driver for the radio control and I want to run both drivers with orbitron data.

tnx ... Philipp.

is there still a driver existing, running CAT-interface for Yaesu FT-736 ?? Or code for other TRX-interface written as an myDDE client?

tnx info

Philipp, dl4abr.

MR, There is NO easy way to calculate lat/lon data from TLE. Using of SGP/SDP models are required to get LOC/VEL ECI vectors, then some math to transform these vectors to data you need. Please find some source code at

Marco, As I see Kansas City Tracker rotor control is not supported by WiSP DDE Client. So there can be problem to use this one with Orbitron. Seems that someone should write driver for it :)

Its great Program thanx for keeping it free. I was wondering if it was possible to show math equations used. Like if i want to calculate latitude and longitude from TLE. What equations i need to use? I tried using some formulas i found in some books but my answers just dont match with the programs. :(

Hi Sebastian,

is there a way to control a Kansas City Tracker rotor control board from Orbitron?

I apologize if the answer is already online... I have not found it.

kev, is the master source of TLE. is only redistributor. So may contain a bit newer data. It can be important to use for Shuttle TLE or so :)

awesome program and very easy to use! i was just wondering what is the difference between the tle files provided by space-track and those by celectrack? is the difference in quality or quantity and why should i set up an account via space-track because the default in orbitron works just fine.(because the registration page is not secure and they do ask for personal info)

Hi Sebastian - very nice job ;-)
sorry for asking that, maybe can find a early respons.
how can make communication between Winrotor interface and Orbitron software. I'm not expert on that and speaking very bad english !

Salomão, Yes, feel free to create your own TLE files and load it. Please make sure, you obey TLE files specification.

LOve the web-site . postcard to follow . I am in the satellite communications business - sales and service . ( sat. radio , tv , telephone and internet . As well as GPS tracking systems )
I told one of my suppliers about your website . He was excited and decided to add your website to his newsletter that he sends to his satellite internet resellers . ( aka Direcway )

Ahhh, I now see that the TS-2000 simply does not allow both A and B radios to be on the same band, at least in SAT mode. I now must update the firmware for PL tone in SAT mode too!

A new challenge or two is good!

Very nice program. My card will be sent.

Using WiSP DDE from another app works in most cases (better than in intended app!) but does not use correct uplink freq for ISS. It defaults to 29.5 FM and when I try to force 145.99 from the dropdown it either does not change the uplink frequency. Is this data stored where I can correct it? Thanks

Gooooooood Work
It's a nice piece of software.

Just wondering:
Can I create a new file with two line elements, and place it on the "tle" folder and select it?
I may be doing it the wrong way.

Keep up the good work!
I'll be sending you my card next Monday.

Paul, Pocket PC version is not in planned now. No motivation to make such one, no hardware ;)
