AMSAT-DL'S ERMINAZ satellites have completed frequency coordination with
the IARU.
The ERMINAZ mission is a syndicated multi-PocketQube mission with a total
of 7 PQs under the leadership of AMSAT-Germany, which also holds the launch
contract with RFA under DLR support. The project is in collaboration
between AMSAT-DL, AMSAT-EA (Spain), ESERO-Germany (Bochum Observatory) and
Libre Space Foundation (Greece). The mission is to promote, advance and
develop knowledge about space and amateur radio. ERMINAZ-1U & ERMINAZ-1V
will transmit telemetry, images, provide a digipeat/store/forward
functionally to all radio amateurs worldwide. ERMINAZ-1U will operate in
the UHF amateur satellite band, while ERMINAZ-1V will operate in the VHF
amateur satellite band. Only non-proprietary, open source and documented
protocols, accessible to radio amateurs, will be used. This includes CCSDS
telemetry, CW beacon, SSDV images, digipeater, AX.25 und possibly other
modes. Telemetry and sensor data from radiation sensor and triaxial
accelerometer / gyroscope / magnetometer will allow any radio amateur to
participate by extending his knowledge about space. In addition, a
digipeater and store & forward function will allow licensed radio amateurs
to use ERMINAZ-1U/1V as a relay to communicate with other radio amateurs
worldwide. The mission will conduct several experiments with different
types of modulations, bandwidths, data rates and framing schemes: GFSK with
data rate from 9600 up to 19200 GFSK with data rate from 9600 up to 19200
bits/s GMSK with data rate from 9600 up to 19200 bits/s BPSK with data rate
from 9600 up to 19200 bits/s QPSK data rate from 19200 up to 38400 bits/s
Frames will using three different framing schemes configurable upon the
mission requirements: CSDS (residual or suppressed carrier) or IEEE
802.15.4 (preamble, sync) or AX.25. Planning a launch by RFA-Rocket Factory
Augsburg AG from SaxaVord Spaceport into a 500km polar orbit not earlier
than August 2024 together with UNNE-1 (HADES-E) and MARIA-G (HADES-F) from
AMSAT-EA and QUBIK 5 from LibreSpace.
Up and downlinks on 145.965 MHz (ERMINAZ-1V) and 435.775 MHz (ERMINAZ-1U)
have been coordinated.
