AO-40 RUDAK Frequencies

The RUDAK team is working to load software, confirm RUDAK's health, and begin collecting data from the experiment modules that depend on RUDAK for communication.

During this testing phase, we invite everyone with 9k6 digital satellite capabilities to listen to RUDAK. More information about what you may hear during early operations is available on our telemetry page. Once the filesystem software is fully loaded, programs like WISP will also be useful for capturing files.

During initial testing, there will be a large number of packets in the downlinks that contain software debugging information, much of which will be turned off after the testing phase is complete.

All initial operations will use the two hardware 9k6 modems on each of the two RUDAK processors. Their downlink frequencies as used during launch integration are as follows:

			   U	     S1		S2	    X

    RUDAK A 9k6 0	436.006	  2400.768   2401.747	10451.561
            9k6 1	435.982	  2400.740   2401.720	10451.536

    RUDAK B 9k6 0	436.122	  2400.887   2401.867
            9k6 1	436.109	  2400.870   2401.847

Initial testing is focussed on RUDAK A 9k6 0 via the S2 transmitter at 2401.747 Mhz.

There is no 10Ghz downlink from RUDAK B. Instead, it has a connection to the 24Ghz transmitter, but the hardware 9k6 modems fall outside the passband, and so that downlink will only be useful once the DSP modems are in use. Likewise, the hardware 9k6 modems fall outside the V downlink passband, and so a DSP modulator will also be required for RUDAK to be heard on the 2 meter downlink.

During the testing phase, all RUDAK uplinks are reserved for use by the RUDAK team. The frequencies of the various uplinks will be broadly communicated once RUDAK is released for general use.
