Information for Radio Amateurs

Two Line Elements (TLE)

The NORAD-ID of SONATE-2 is 59112 and its international designator is 2024-043Q. Current TLE information can be found on the CelesTrak website.

Telemetry Downlink

During passes over our ground stations in Germany the telemetry downlink of SONATE-2 will be activated.

• Frequency: 437.025 MHz
• Modulation: 9k6 G3RUH GMSK (F1D)
• Protocol: AX.25

The protocol format used for encoding the telemetry frames can be found >>here<<.
Recorded AX.25 frames can be forwarded to sonate-2@uni-wuerzburg.de

CW Beacon

SONATE-2's CW Beacon is only sporadically used mainly during LEOP for launch object identification. If activated, a beacon with the callsign of the satellite DP0SNX is transmitted at regular intervals as CW Morse code.

• Frequency: 145.840 MHz
• Modulation: Morse code CW (A1A)
• Interval: 30 sec

APRS Digipeater

The APRS digipeater on SONATE-2 operates in half-duplex operation. The digipeater is only active when published below. When activated, it will transmit a greeting message every 2 minutes. Make sure to include SONATE-2's callsign DP0SNX in the APRS route.

• Frequency: 145.825 MHz Up/Down
• Modulation: 1k2 AFSK (F2D)
• Protocol: AX.25
• TX Power: 500mW

Activation Schedule [Last Update: 09/08/2024]

The APRS digipeater on SONATE-2 was active at the following times. Times in the future show planned activation slots. Due to unforeseen circumstances, the planned times can also change at short notice. The begin of an APRS event is usually announced on our X account @JMUSpace.

SSTV Downlink

Regular downlinks of SSTV images captured by SONATE-2's on-board cameras are planned. The SSTV downlinks are only active during the times when published below. Only a single images is transmitted at the specified timestamps (all in UTC).

• Frequency: 145.880 MHz
• Modulation: Martin M1 SSTV FM (F3F)
• TX Power: 500mW

Transmission Schedule from 05 – 08/07/2024 in UTC [Last Update: 05/07/2024]

The following table shows the UTC times of the planned SSTV transmissions of SONATE-2. A single image is transmitted once at these times. Due to unforeseen circumstances, the scheduled times may change at short notice. The begin of a SSTV event is usually also announced on our X account @JMUSpace.
