EmilHOST
However, when I asked the question, you know, "What makes JTTY better than, let's say, PSK31?" And I got quite a screen full of, uh, items.
EmilHOST
Uh, the modulation type is 4GSK versus the phase shift keying of, uh, PSK, the BPSK and the QPSK, if you remember.
EmilHOST
And the bandwidth, about 125 k- uh, hertz instead of 31 hertz, even though they had different sizes of the BSKs and PSKs.
EmilHOST
One of them was 125, I think.
Will RogersHOST
Each of the three Erminas II spacecraft will transmit telemetry and science data from onboard radiation sensors and triaxial accelerometers, gyroscopes and magnetometers, downlink SSDB images, and provide a digipeter and store and forward functions, allowing licensed amateurs to use the satellites as relays to communicate with one another worldwide.
Will RogersHOST
Only non-proprietary open-source and documented protocols will be used, including CC-SDS telemetry, a CW beacon with callsign identification, SSDV, and AX25 along with in-flight experiments using GFSK, GMSK, and BPSK modulation at data rates from 600 to 19,200 BPS and both CC-SDS and IEEE 802.15.4 framing.
Will RogersHOST
The IARU has coordinated the following frequencies.
Will RogersHOST
ERMINAZ 2U will operate in the UHF amateur satellite band on 435.900 MHz, while ERMINAZ 2V and ERMINAZ 2X will operate in the VHF band on 145.920 MHz and 145.960 MHz, respectively.
