Dear all,
Our HADES-D satellite has been commissioned. After a trial period in which its behavior has been tested at the radioelectric, systems, and energy performance levels, the FM repeater is left active for general use.
Almost certainly, HADES-D appears to be NORAD object 58567. Some of the TLE databases have already included it.
1 58567U 23174CY 23350.05493917 .00017045 00000-0 92316-3 0 9990 2 58567 97.4794 62.4136 0016027 150.3868 209.8275 15.14574024 5799
We remember that the repeater works with FM/FSK (MSK144 has been tested too) with an uplink frequency of 145,875 MHz and a downlink frequency of 436,663.5 MHz (a bit lower than the 436.666 MHz expected). We have been able to verify that the modulation is more appropriate by narrowing the bandwidth, so it is recommended to use NFM in those devices allowing it.
AMSAT-EA is drafting a use and operation manual, which will be published shortly and which will indicate in detail some of the characteristics of the satellite and its working modes. Although it is not definitive, Amsat-EA is considering some special operating options such as reserving a day of the week exclusively for digital communications following the example we know with the AO-92.
Finally, please, remember that, as far as we know, HADES-D is the first satellite with FM repeater service mounted on a pocketqube platform. This standard is the smallest in terms of normalized satellite sizes. HADES-D size is 8x5x5 cm. Its panel surface and battery size are much smaller than the rest of the satellite repeaters in use, so HADES-D is not comparable to most of them either in radiated power or signal strength. HADES-D should be considered a QRP satellite.
