Dear Community, We've been working with USRP and Gnu Radio for various tasks in our Cubesat project for some time now. Recently we thought of using the set-up (Linux Ubuntu, USRP (1) and Gnu Radio / GRC) for receiving, decoding and recover data from our ground based payload. We are not flying the USRP onboard our satellite but want to use it for the in-field test of the ground based payload. Through-out the project we've been searching for any BPSK receiver (anything like: an off-the-shelve radio, add-on modules for existing radios, DIY radio kit or perhaps USRP and Gnu Radio). Nothing. Yes, I have searched this forum for previous posts (I found 89 threads on BPSK), none of them have a solution/design. I seriously doubt that making a regular BPSK receiver that goes all-the-way, i.e. recovers the transmitted data has ever been done. We haven't found any trace of anything be it commercial, research or DIY.
Desperate times calls for desperate measures. If you can make a BPSK receiver that will run in Gnu Radio (preferably GRC as I'm not a programmer) I will buy you a cake of your own choice from one of the internet cake delivery companies. If you want "1. prize details" have a look at our webpage with the offer: http://www.dtusat.dtu.dk/index.php?id=112 Dead-line is 11. May 2009 - after that the conclusion is: BPSK is not an I.R.L. thing but merely a mathematical curiosa and we'll go for one of the more ordinary modulations. Questions are off course welcome. PS: The transmitter run at 868 MHz.
